Answer:
The functions each have a positive Slope
a.)True, False
Step-by-step explanation:
Function A Slope: (y2-y1)/(x2-x1) = (7-3)/(2-1) = 4
Function B Slope: Count Four Boxes up from the 2 intercepts and then 2 over --> 4/2 = 2
These are both positive but 4 does not equal 2
a.) We have just proved that they have different slopes now we must determine if they have the same b. Because we know the slope of Function A we can simply move backward to get to x=0
When X=0 y= 3-4 = -1 And because in Function B we can clearly see the b at y=4 this is false.
Hope this helps and makes you have an Awesome Day!

Let z = 8 – 3i, and z2 = a + bi. What are the values of a and b?
The values of a and b from the given complex numbers is 8 and -3 respectively.
The standard form of representing complex number is expressed as z = x + iy
Given the complex numbers z = 8 – 3i, and z2 = a + bi
To get the values of a and b, we need to compare both expressions as shown:
For the real part;
a = 8
For the imaginary part:
-3i = bi
-3 = b
Swap
b = -3
Hence the values of a and b from the given complex numbers is 8 and -3 respectively.

The domain is {x ∈ R : x ≠ 0} (where R is the set of all real numbers), since x⁶ is a non-negative number for all real numbers x.
The range is R or the interval (-∞, ∞).
During a job interview, you are asked to rate on a scale of 1 to 5 how happy you are. What type of test is the interviewer giving you
Answer:
Probably how much you want this job, if you say 0, than they are prob gonna assume you dont want to do this job, and you wont do your best. If you say 5, then you do want this job and your excited and youll give your all

Elimination Method: 6x - 4y = -24 and 4x + 5y = -2
Answer:
[tex](-2;-6)[/tex]
Step-by-step explanation:
First of all, let's rewrite the first one after dividing both sides by 2.
[tex]\left \{ {{3x-2y=-12\atop {4x+5y=-2}} \right.[/tex]
Now, let's pick one you want to eliminate.
Eliminating x: Let's multiply the first one by 4, the second by 3, and subtract one from the other. Rest is simply solving an equation in one variable
[tex]4I-3II : 12x-8y-12x+15y = -48 - (-6)\\7y = -42 \rightarrow y= -6[/tex]
Eliminating y: Let's multiply the first by 5, the second by 2, and add them together. Rest is simply solving an equation in one variable
[tex]5I+2II: 15x -10y +8x +10y = -60 +4\\23x = -56 \rightarrow x=-2[/tex]

You have 2\3 of a pizza left from yesterday. You divide it into 4 equal pieces. What fraction of the pizza is each piece?
====================================================
Explanation:
Let's say for example this pizza had 6 slices to start with. Two-thirds of this is (2/3)*12 = 4 slices. So you have 4 slices left over from yesterday. Then let's say you hand one slice to each of your four friends. Each friend would have 1/6 of the original pizza.

Find the discriminant of the quadratic equation x2 + 6x + 14 = 0 and use it to determine the number and types of solutions.
b2 − 4ac
−20; Two nonreal solutions
−20; One real solution
92; Two real solutions
92; One real solution
Answer:
-20;two nonreal solutions
Step-by-step explanation:
D=b^2-4ac=36-14*4=-20
because after that you need to write D^1/2 and D is <0,the solutions are unreal
Answer:
-20 and two nonreal solutions.
Step-by-step explanation:
The discriminant of a quadratic equation uses the equation:
[tex]b^2 - 4ac[/tex]
Where the value of this calculation can tell you what solutions there are, plug known values in:
[tex]x^2 + 6x + 14 = 0\\a = 1\\b = 6\\c = 14\\[/tex]
[tex]b^2 - 4ac\\6^2 - 4(1)(14)\\36 - (4 * 14)\\36 - 56 = -20[/tex]
As -20 < 0, this means that there is not a real solution, resulting in the first option being correct.

8x + 14 y = 4
-6x - 7y=-10
Answer:
y = -2 and x = 4
Step-by-step explanation:
8x + 14y = 4
-6x - 7y = -10
First, find the lowest common multiple of 8 and 6 (which is 24). Multiply the first equation by 3:
8x + 14y = 4
3(8x + 14y) = 3(4)
24x + 42y = 12
Multiply the second equation by 4:
-6x - 7y = -10
4(-6x - 7y) = 4(-10)
-24x - 28y = -40
Now, add the two equations together:
24x + 42y = 12
-24x - 28y = -40
24x + -24x = 0
42y + -28y = 14y
12 + -40 = -28
14y = -28
Divide both sides by 14:
14y ÷ 14 = -28 ÷ 14
y = -2
Plug this known variable back into the first equation:
8x + 14(-2) = 4
8x + (-28) = 4
8x - 28 = 4
Add 28 to both sides:
8x - 28 + 28 = 4 + 28
8x = 32
Divide both sides by 8:
8x ÷ 8 = 32 ÷ 8
x = 4
So y = -2 and x = 4.

Step-by-step explanation:

Answer:
[tex]y=-\frac{4}{3} x+4[/tex]
Step-by-step explanation:
Slope-intercept form is written in [tex]y=mx+b[/tex]
So, to solve, we must separate y onto one side and make its coefficient one.
[tex]4x+3y=12[/tex]
Subtract 4x on both sides.
[tex]3y=12-4x[/tex]
Divide both sides by the coefficient of [tex]y[/tex], which is 3.
[tex]\frac{3y}{3} =\frac{12-4x}{3}[/tex]
Simplify.
[tex]y=4-\frac{4}{3} x[/tex]
Rewrite this equation into standard form by changing the order of [tex]mx[/tex] and [tex]b[/tex]
[tex]y=-\frac{4}{3} x+4[/tex]

[tex]\\ \sf\longmapsto side^3=5[/tex]
[tex]\\ \sf\longmapsto side=\sqrt[3]{5}[/tex]
[tex]\\ \sf\longmapsto side=2.2in[/tex]
Side gets tripled
New side=2.2(3)=6.6in[tex]\\ \sf\longmapsto Volume=6.6^3[/tex]
[tex]\\ \sf\longmapsto Volume=287.4in^3[/tex]
Answer:
135 in³Step-by-step explanation:
If the side of the cube is s and volume is 5 and you triple the side then:
V₁ = s³ = 5The enlarged cube has the volume:
V₂ = (3s)³ = 3³*s³= 27s³ = 27*5 = 135 in³
