Answer:
44
Step-by-step explanation:
954/22=43.3636363636
Answer:
A
Step-by-step explanation:
you can find the vertex of each equation and then compare to the graph
x = -b/2a
A) x = -(-9)/2(1); x = 9/2 or x = 4 1/2
plug 4 1/2 into equation as 'x' to find 'y'
y = (9/2)² - 9(9/2) + 20
y = 81/4 - 81/2 + 20
y = 81/4 - 162/4 + 80/4
y = -81/4 + 80/4
y = -1/4
the only option with a vertex at (9/2, -1/4) is A
Answer:
Step-by-step explanation:
Statement is not true because
0 is not equal not 38
No x here.
7/8(x-1/2)= -49/80
Multiply the bracket by 7/8
7/8x-7/16= -49/80
Move -7/16 to other side. Sign changes from -7/16 to +7/16
7/8x-7/16+7/16= -49/80+7/16
7/8x= -49/80+7/16
Find common denominator for 7/16 which is 5. Multiply 5 for the numerator and denominator.
7(5) / 16 (5)
= 35/80
7/8x= -49/80+35/80
7/8x= -14/80
Reduce -14/80 , divide by 2
(-14) /2=7 , 80/2= 40
-14/80= -7/40
7/8x= -7/40
Multiply by 8/7
7/8x*8/7= -7/40 * 8/7
Cross out 7 and 7 , and divide by 7. Cross out -7 and 7 and divide by 7. Cross out 40 and 8 divide by 8.
x= -1/5
Answer: x= -1/5 - G.
