Answer:

c. d. different slopes; same y-intercept

for all the equations, when x = 0, y = -2

apart from the last equation which has no x-intercept.

They have different slopes i.e

y=x-2 has a slope of 1

y=2x-2 has a slope of 2

y=x-2 has a slope of 1

y=-2 has no slope

Solve the equation 4s2+32s=60 by completing the square

lord [1]

Answer:

s = -4 ± √31

Step-by-step explanation:

Given 4 $s^{2}$ + 32s = 60

divide by 4 throughout

$s^{2} + 8s = 15\\s^{2} + 8s + (\frac{8}{2}) ^{2} = 15 + (\frac{8}{2}) ^{2}$

$(s + 4)^{2} = 31\\s + 4 = \sqrt{31}$

s = -4 ± √31

Three times the sum of a number and seven is two less than five times the number.

m_a_m_a [10]

3 (x + 7) = 5x - 2
3x + 21 = 5x - 2
3x - 5x = -2 - 21

-2x = -23
x = -23/-2
x = 23/2
