1 answer:
ohaa [14]3 years ago
3 0

Answer:

C

Step-by-step explanation:

given 7 - 4(x - 1) = 20 ( Step 1 is to distribute the parenthesis )

7 - 4x + 4 = 20  ( not 7 - 4x + 1 = 20 ← - 1 is multiplied by - 4 )

Step 1 ← is incorrect → C

Find two integers whose sum is -9 and product is -10
BigorU [14]

Step-by-step explanation:

if the two integers are x and y

xy=-10

x+y=-9

x+(-10/x)=-9

x2+9x-10=0

(x-1)(x+10)=0

x=1 or x=-10

if x=1, y=-10

if x=-10, y=1

so the two integers are 1 and -10
