Letter a.
Y= will produce a parabola opening up or down.

The x coordinate of the vertex is switched to be outside the parenthesis, y coordinate is inside

The function is given by the formula f(x)=3x+2.

Naily [24]

Answer:

(a) f(7) = 23

(b) x = 13/3

Step-by-step explanation:

Step 1: Define

f(x) = 3x + 2

(a) f(7) is x = 7

(b) f(x) = 15

Step 2: Substitute and Evaluate

(a) f(7) = 3(7) + 2

f(7) = 21 + 2

f(7) = 23

(b) 15 = 3x + 2

13 = 3x

x = 13/3

Find the value of r so the line that passes through each pair of points has the given slope.

3241004551 [841]

Answer:

r = 1

Step-by-step explanation:

slope = change in y / change in x, so:

change in y / change in x = 2/3

5 - r / 7 - 1 = 2/3

5 - r / 6 = 2/3

$\frac{5-r}{6}=\frac{2}{3}$

now solve this equation.

first, multiply both sides by 6 to get rid of the fraction:

$5 - r = 4$

subtract 5 from both sides

$-r=-1$

multiply both sides by -1

$r=1$
