Find the slope of the line give these two points: (0,5) and (-7, -8) *
Answer:
m=13/7
Step-by-step explanation:
the equation for slope (m) is (y2-y1)/(x2-x1)
the given points are (0,5) and (-7,-8)
we can label them:
x1=0
y1=5
x2=-7
y2=-8
now substitute into the equation
m=(-8-5)/(-7-0)
m=-13/-7
m=13/7
the slope is 13/7

After distributing, which equation is equivalent to -4(3x + 2) = 10a.-12x -8 = 10b.-12x + 8 = 10c.-12x -6 = 10d.-12x + 6 = 1
Answer:
Option A: -12x-8=10 is the correct answer.
Step-by-step explanation:
Given equation is:
-4 (3x+2) = 10
We will distribute the equation by multiplying the terms inside the brackets with -4.
Therefore,
-4*3x + 2*-4 = 10
-12x +(-8) = 10
-12x - 8 = 10
The equation -4 (3x+2) = 10 will become -12x-8=10 after distributing.
Hence,
Option A: -12x-8=10 is the correct answer.
Find the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1)
Answer:
The coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1) are [tex]\mathbf{(13,\frac{-9}{2})}[/tex]
Step-by-step explanation:
We need to find the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1)
The midpoint of line segment can be found using formula:
[tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
We have [tex]x_1=14, y_1=-8, x_2=12, y_2=-1[/tex]
Putting values and finding midpoint
[tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\Midpoint=(\frac{14+12}{2},\frac{-8-1}{2})\\Midpoint=(\frac{26}{2},\frac{-9}{2})\\Midpoint=(13,\frac{-9}{2})[/tex]
So, the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1) are [tex]\mathbf{(13,\frac{-9}{2})}[/tex]

You have to find the common difference, the term named in the problem, and the explicit formula.
Question 1
Given the sequence
31, 61, 91, 121,...
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
computing the differences of all the adjacent terms
61 - 31 = 30, 91 - 61 = 30, 121 - 91 = 30
The difference between all the adjacent terms is the same and equal to
d = 30
As the first term of the sequence is:
a₁ = 31
now substituting a₁ = 31 and d = 30 in the nth term of the sequence
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_n=30\left(n-1\right)+31[/tex]
[tex]a_n=30n+1[/tex]
Now, putting n = 36 to determine the 36th term
[tex]a_n=30n+1[/tex]
[tex]a_{36}=30\left(36\right)+1[/tex]
[tex]a_{36}=1080+1[/tex]
[tex]a_{36}=1081[/tex]
Thus, the 36th term is:
[tex]a_{36}=1081[/tex]
Question 2
Given the sequence
-34, -44, -54, -64, ...
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
computing the differences of all the adjacent terms
[tex]-44-\left(-34\right)=-10,\:\quad \:-54-\left(-44\right)=-10,\:\quad \:-64-\left(-54\right)=-10[/tex]
The difference between all the adjacent terms is the same and equal to
[tex]d=-10[/tex]
As the first term of the sequence is:
a₁ = -34
now substituting a₁ = -34 and d = -10 in the nth term of the sequence
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_n=-10\left(n-1\right)-34[/tex]
[tex]a_n=-10n-24[/tex]
Now, putting n = 26 to determine the 36th term
[tex]a_n=-10n-24[/tex]
[tex]a_{26}=-10\left(26\right)-24[/tex]
[tex]a_{26}=-260-24[/tex]
[tex]a_{26}=-284[/tex]
Thus, the 26th term is:
[tex]a_{26}=-284[/tex]

Jojo spends t minutes practicing the guitar. He spends 20 minutes less than twice that amount of time doing homework. Which expression shows the number of minutes Dion spends doing homework?
Answer: 2t - 20
Step-by-step explanation:
Jojo spends t minutes doing homework.
He then spends 20 minutes less than twice that amount of time doing homework.
For homework therefore, let us breakdown the time spent:
Spends twice the amount of time = 2tSpends 20 minutes less than twice = 2t - 20When doing homework, Jojo therefore spends:
= 2t - 20

Jesse owns a sporting goods store that sells skis and snowboards. The store earns a profit of $52 for each ski sold and a profit of $64 for each snowboard sold. If Jesse's store sells a total of 83 pairs of skis and snowboards and earns a profit of $4892 in November, how many pairs of skis and snowboards did the store sell that month
Answer:
9
Step-by-step explanation:
I multiply 52 and 83 and get 4316. 4892 - 4316 is 576. 576 divided by 64 is 9!
Answer: they sold 35 skis and 48 snowboard
Step-by-step explanation:
52 x 35 = 1820
64 x 48 = 3072
1820 + 3072 = 4892

An airplane flies at an altitude of 14,690 feet while a submarine is submerged at a depth of 521 feet below the surface of the ocean. What is the difference between these two elevations?
Answer:
15,211 feet
Step-by-step explanation:
According to the question, given data are as follows:
Airplane altitude = 14,690 feet above
Submarine depth = 521 feet below
So, let the difference between these two elevation be d,
So, we can calculate difference by using following formula:
Difference = Airplane altitude + Submarine depth
By putting the value, we get
Difference = 14,690 + 521
= 15,211 feet

A pet store decides on no longer selling Smelly Cat litter that costs s dollars per bag. In order to quickly sell the rest of its supply, it marks down the bags by 59%.
Answer:
Expanded Expression: 1s- 0.59s
Simplified Expression : 0.41 s
Discounted Price= $ 2.46
Step-by-step explanation:
Directions: Write two markup or markdown expressions for each problem below. Then substitute the given value for the variable and evaluate the expression.
The Discounted Price is found out after deducting the discount from the original price.
Let 100 be the sale price then the discount is 59 and the discounted price would be 100- 59= $41
Sale Price = $ s
Discount = 59% of $ s
Discounted Price = s- (100-59)/100*( $s) = 1s- 0.59s = 0.41 s
Expanded Expression Simplified Expression
1s- 0.59s 0.41 s
Find the sale price of the Smelly Cat litter, when the regular price was $6 per bag.
Sale Price = $ 6
Discount = 59% of $ 6
Discount= (59/100) $6= $ 3.54
Discounted Price= Sale Price - Discount= $6 - $ 3.54= $ 2.46
