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

$r=1$

write The equation of the line that passes through the point parentheses (6 , 4) and is parallel to the equation 2X plus 3Y equa

aliina [53]

Answer:

2x + 3y - 24 = 0

Step-by-step explanation:

2x + 3y = 18

3y = -2x + 18

y = $\frac{-2}{3}$ x + 6

m = -2/3

y - 4 = -2/3(x - 6)

3y - 12 = -2x + 12

2x + 3y - 24 = 0

For f(x)=2x+1 and g(x)=x^2-7, find (f+g)(x) A. 2x^2-15 B.X^2+2x-6 C.2x^3-6 D.x^2+2x+8

Advocard [28]

Answer:

C

Step-by-step explanation:

(f + g)(x) = f(x) + g(x) , thus

f(x) + g(x)

= 2x + 1 + x² - 7 ← collect like terms

= x² + 2x - 6 → C
