Words Expression
The Value of the Expression
a. 50 times the sum of 64 and 36 ... 50 x (64+36) = 50x (100) = 5000
50 x 64 + 36 )
5000
b. Divide the difference between 1,200 and 700 by 5 ...(1200-700) / 5 = 500/5 = 100
(1,200 - 700): 5
100
C. The sum of 3 fifteens and 17 fifteens
... +
=
=
45 + 255
d. 15 times the sum of 14 and 6 ... 15 x (14 + 6) = 15 (20) = 300
e.
10 x (250 +45) ...10 times the sum of 250 and 45
f.
(560 + 440) x 14... 14 times the sum of 560 and 440
Hope this helps
Convert to vertex form
or easier
for y=ax²+bx+c
the x value of the vertex is
and the y value is found by subsituting the x value in for x
so
y=1x²+4x+11
a=1
b=4
the x value of the vertex is
the y value is found by subsituting -2 for x
y=(-2)²+4(-2)+11
y=4-8+11
y=7
the vertex is (-2,7)
