Answer:
k = -4
Step-by-step explanation:
Given system of linear equations:
[tex]\begin{cases}4x - 8y = -3\\2x + ky = 10\end{cases}[/tex]
Rewrite the given equations so that they are in slope-intercept form.
[tex]\begin{aligned}4x-8y&=-3\\4x&=8y-3\\4x+3&=8y\\\dfrac{4x+3}{8}&=y\\y&=\dfrac{1}{2}x+\dfrac{3}{8}\end{aligned}[/tex]
[tex]\begin{aligned}2x+ky&=10\\ky&=-2x+10\\y&=\dfrac{-2x+10}{k}\\y&=-\dfrac{2}{k}x+\dfrac{10}{k}\end{aligned}[/tex]
An inconsistent system of linear equations has no solutions and therefore the lines are parallel.
Parallel lines have the same slope:
[tex]\implies \dfrac{1}{2}=-\dfrac{2}{k}[/tex]
[tex]\implies \dfrac{1}{2}k=-2[/tex]
[tex]\implies k=-2 \cdot 2[/tex]
[tex]\implies k=-4[/tex]
Answer:
The system is inconsistent if k = -4--------------------------
Inconsistent system is a system with no solutions.Parallel lines are inconsistent.Parallel lines have equal slopes but different y-intercepts.Equation in the standard form ax + by = c has:
slope = - a/b,y-intercept = c/b.Given system:
4x - 8y = -32x + ky = 10Compare the slopes of the two lines:
- 4 / - 8 = 1/2 and - 2/kWe need them to be equal:
1/2 = - 2/kk = - 4Compare the y-intercepts of the two lines:
- 3/ - 8 = 3/8 and10 / kWe need to confirm they are not same:
3/8 ≠ 10/k3/8 ≠ 10/-4, correct as positive and negative numbersConfirmed, so k = -4 is our solution.
Jim Moore opens a new savings account. He deposits $12,000 at 12% compounded semiannually. At the start of the fourth year, Jim deposits an additional $50,000 that is also compounded semiannually at 12%. At the end of six years, the balance in Jim Moore's account is
Multiple Choice

$93,932.28
$95,072.31

After six years, Jim Moore's account will have a balance of $69,341 thanks to compound interest.
What is compound interest?Interest that is added to a loan and deposit sum is known as compound interest. In our everyday lives, it is the notion that is employed the most frequently. Compound interest is calculated as a sum using the interest and principal accrued over time. Compound interest versus simple interest differ primarily in this way.
As per the given information in the question,
The account in this issue is split up into two distinct investments. The first one is for $12,000 with a 12% compound interest rate over six years. Consequently, the criteria are as follows:
P = $12,000
r = 0.12
t = 6 years.
[tex]A_1(t)=P(1+\frac{r}{n} )^n^t[/tex]
[tex]A_1(6)=12000(1+\frac{0.12}{6} )^(^2^)^(^6^)[/tex]
A₁(6) = $15219.
The value of the second investment, which is $50,000 and is likewise compounded semi-annually at 12%, will be as follows at the conclusion of the fourth year:
[tex]A_2(t)=P(1+\frac{r}{n} )^n^t[/tex]
[tex]A_2(2)=50000(1+\frac{0.12}{6} )^(^2^)^(^2^)[/tex]
A₂(2) = 54122
Hence,
A(6) = A₁(6) + A₂(2)
A(6) = 15219 + 54122
A(6) = $69341

Find the area of the circle x2 + y2 + 4x – 8y – 29 = 0. in sq.units
Answer:
A ≈ 154 units²
Step-by-step explanation:
the area (A) of a circle is calculated as
A = πr² ( r is the radius)
to calculate the area we require to know r
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
given
x² + y² + 4x - 8y - 29 = 0
collect x and y terms together and add 29 to both sides )
x² + 4x + y² - 8y = 29
obtain standard form for circle using the method of completing the square
add ( half the coefficient of the x/ y terms)² to both sides
x² + 2(2)x + 4 + y² + 2(- 4)y + 16 = 29 + 4 + 16
(x + 2)² + (y - 4)² = 49 = r² ← in standard form
Then
A = πr² = π × 49 ≈ 154 units² ( to the nearest whole unit )

How to graph:
y= 2x - 5
Answer:
see attached
Step-by-step explanation:
You want to graph y = 2x -5.
GraphOften, the easiest way to graph a linear equation in slope-intercept form is to graph the y-intercept point, then use the slope to identify one or more additional points on the line. The graph is the line through the plotted points.
Slope-intercept formThe slope-intercept form of the equation of a line is ...
y = mx +b
where m is the slope, and b is the y-intercept.
The y-intercept is the point on the y-axis where the line crosses it. The coordinates there are (0, b).
Here, we have y = 2x -5, so m=2 and b=-5. The y-intercept point is (0, -5).
The slope is the ratio of "rise" to "run" for the line. A slope of 2 means the line rises 2 units for each 1 unit it goes to the right. That means (0 +1, b+2) will be another point on the line: (1, -3).
in the context of assessing wound healing as an indicator of immune functioning, which of the following impairs the inflammatory response that initiates wound repair?
Acute ethanol exposure can hinder the early inflammatory response, which can delay wound healing.
Hemostasis, inflammation, proliferation, and remodeling are the four perfectly timed steps that make up the normal biological process of wound healing in the human body. All four phases of wound healing must take place in the right order and amount of time for healing to be successful. Numerous factors may affect one or more stages of this procedure, impairing or causing incorrect wound healing.
Each stage of wound healing has certain milestones that must occur in order for normal healing to progress. In order to identify the differences inherent in chronic wounds that prevent healing, it is important to review the process of healing in normal wounds
In summary, acute ethanol exposure can lead to impaired wound healing by impairing the early inflammatory response, inhibiting wound closure, angiogenesis, and collagen production, and altering the protease balance at the wound site.

division- answer in gallons and quarts. no fraction or decimals.
3/10gallons 11 quarts
1 gal =4 quarts
Answer:
Step-by-step explanation:
To solve this problem, we need to divide 3/10 gallons by 1 gallon, which is equal to 4 quarts.
First, let's convert the fraction 3/10 to a decimal by dividing the numerator by the denominator: 3 / 10 = 0.3
Then, we can divide 0.3 gallons by 1 gallon to get the equivalent number of gallons in quarts: 0.3 gallons / 1 gallon = 0.75 quarts
Since 1 quart is equal to 0.25 gallons, 0.75 quarts is equivalent to 3/4 of a gallon.
Finally, we can add the number of quarts given in the problem (11 quarts) to the number of quarts equivalent to the number of gallons (3/4 of a gallon, or 3 quarts). This gives us a total of 14 quarts, which is equivalent to 3 and 1/2 gallons.
Therefore, the final answer is 3 gallons and 11 quarts.

Answer: $900
Step-by-step explanation:
1 puppy cost- $150
150×6 puppies= $900 dollars
Answer:
She would make 900
Step-by-step explanation:
You can split the multiplication for example, I split the hundreds and tens. First you multiply 6 to 100. We know that 6×1=6 so we use that by taking out the two zeros in the beginning and adding them back after multiplying by 1. It would then become 6×100 ~> 6×1(⁰⁰) ~> 6 then add back the zeros which would then become 600! Now we multiply 6 to 50. We use the same method again. 6×5(⁰) ~> 30(⁰) ~> 300. Now we add those two products together. 600+300=900

A division is one of the fundamental mathematical operations that divides a larger number into smaller groups with the same number of components. How many total groups will be established, for instance, if 20 students need to be separated into groups of five for a sporting event? The division operation makes it simple to tackle such issues. Divide 20 by 5 in this case. 20 x 5 = 4 will be the outcome. There will therefore be 4 groups with 5 students each. By multiplying 4 by 5 and receiving the result 20, you may confirm this value.

In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
2/3 can of paint = 1(1/2) hours
2/3 can of paint = 3/2 hours
Multiply 2/3 on both sides.
2/3 x 2/3 can of paint = 1 hour
4/9 can of paint = 1 hour
Or
2/3 can of paint = 1(1/2) hours
Multiply 3/2 on both sides.
1 can of paint = 3/2 x 3/2 hours
1 can of paint = 9/4 hours
1 can of paint = 2(1/4) hours
Thus,
We can say that,
1 can of paint is used in 2(1/4) hours
4/9 can of paint is used in 1 hour.

find total amount to be repaid. round to nearest cent as needed.
The total amount to be repaid by Neema will be $4135.50
How to calculate the total amount?It was illustrated that Neema bought appliances that cost $3805 at an interest charge of 5% and she will pay back in two years.
Since there is a $500 down payment, the remaining amount will be:
= $3805 - $500
= $3305
Therefore, the interest will be:
= PRT
= $3305 × 5% × 2
= $330.50
Therefore, total amount will be:
= $3305 + $500 + $330.50
= $4135.50

X, Y and Z form the vertices of a triangle, where
∠
YXZ = 62°, XY = 6.1m and XZ = 7.9m.
Calculate the area of the triangle. Round your answer to 1 DP.
Answer:
Step-by-step explanation:
When sides 'z' and 'y' and included angle X is known, the area of the triangle is:
Area (∆XYZ) = 1/2 × yz × sin(X)
1/2 x 7.9 x 6.1 x Sin(62) = 21.27
