Answer:

<h2>Slope of Function B  = -Slope of Function A</h2>

Step-by-step explanation:

To find the right answer we need to calcultate the slope of each function.

Function A is  f(x)=-2x+1

From its expression we can deduct that its slope is m_{A} =-2 because the function is expressed in slope-intercept form where the coefficient of the <em>x </em>is the slope.

Now, function B is defined with a graph line, that intercepts points (-1,-5), (2,1) and (3,3). Using this points we can find its slope using the formula

m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} } \\m_{B} =\frac{3-(-5)}{3-(-1)} =\frac{3+5}{3+1}=\frac{8}{4}=2

So, function A has a slope of -2 and function B has a slope of 2.

Therefore, the last choice compares both slopes, because they are just opposite,

m_{B}=-m_{A}

So, the answer is

<em>Slope of Function B = -Slope of Function A</em>

Answer:

Slope of Function B = – Slope of Function A

Step-by-step explanation:

Slope of function A=-2

Slope of function B=$\frac{3-1}{3-2}=2$

PZZZ help!!!!!<br><br>25 points!
Cerrena [4.2K]

Answer:

Y=1.25x+3.50

Step-by-step explanation:

The problem is linear so it uses y=ax+b form. In this we can set the left group as x and the right group as y. Then use

(y2-y1) / (x2-x1) to find the slope. once the slope is found (1.25) we can find the y intercept by using one of our coordinates with our equation y-ax=b

12.25-1.25*7=b

b=3.5

now we put them all together to make

Y=1.25x+3.50

A shirt is reduced by 22% and now costs £12.48 - how much was it originally?
kow [346]
<span>Here is what you do.

Take the percentage you have and subtract it from 100.
100 - 22 = 78%

Now divide 12.48 by 78%

Which is a solution to the equation 3x2 + 2x − 20 = 2x2 + 15?
qaws [65]

Answer:

33/2

Step-by-step explanation:

6+2x -20= 2×2 +15

-14+2x=19

add 14 to both sides

2x=33

divide 2 in both sides

x=33/2
