Trey believes there is a correlation between the number of texts sent during class and GPA. He collected data and found that the

vichka [17]

Answer: First Option

The slope is −0.4. Starting at 3.8, the GPA will decrease by 0.4 for every text sent in class.

Step-by-step explanation:

The equation of a line has the following form

$y=mx+b$

Where m is the slope of the line and b is the intercept with the axis of the y

In this case, the equation is:

$y = 3.8 - 0.4x\\\\y=-0.4x+3.8$

Observe that

$m = -0.4\\b = 3.8$

So if x represents the number of texts sent during classes, this means that $x\geq 0$

When x increases by one unit then y decreases -0.4. For example when $x=1$ then $y=3.8-0.4=3.4$

Then the greatest value it can take the GPA is 3.8. Therefore we can say that the function starts at y = 3.8.

The answer is the first option

The triangles are similar.

RSB [31]

Answer:

The value of x is 12.

Step-by-step explanation:

In order to find the value of x, we first need to find the scale factor. We can find this by dividing any side of the larger triangle with the corresponding part of the smaller triangle.

28/7 = 4

This means everything in the larger triangle is 4 times as great as the smaller triangle. Knowing this, we can set the larger hypotenuse equal to 4 times the smaller.

6x + 28 = 4(25)

6x + 28 = 100

6x = 72

x = 12
