Answer:
x= -3
Step-by-step explanation:
-3(x+5)=8x+18
-3x-15=8x+18
-3x (+3x) -15=8x (+3x) +18
-15=11x+18
-15(-18)=11x +18 (-18)
-33=11x
-33(divide by 11) = 11x (divide by 11)
-3=x
Answer:
depends on whether you meant (1/2)/4 or 1/ (2/4)
Step-by-step explanation:
1/2 x
---------- = -------------
4 28
Using cross products
1/2* 28 = 4x
14 = 4x
Divide by 4
14/4 = 4x/4
7/2 =x
If you meant
1 x
---------- = -------------
2/4 28
1 * 28 = 2/4 x
28 = 1/2 x
Multiply each side by 2
28*2 = 1/2x*2
56 =x
Answer:
978
Step-by-step explanation:
y= -x²+ 78x - 543
y= ax²+ bx + c
a= -1, b= 78, c= -543
max = c -(b²/4a)
= -543 -(78²/-4)
= -543 + 1521
= 978
