(c)*(d)=8*30+8*4=8*34,=>
c=8
d=34
a+b>a-b, =>a+b=d, a-b=c; =>
{a+b=34
{a-b=8, =>a=b+8 ;
(b+8)+b=34
2b=34-8
b=13
a=13+8=21
Answer: a=21; b=13; c=8; d=34.
Answer:
c
Step-by-step explanation:
a dilation with a scale factor means the image would be twice as big as the pre image
(1/2)x = 2 1/2
Solve for x by dividing both sides by 1/2.
Answer: 7
Step-by-step explanation:
f(x) 3x+1
f(2) = 3(2) +1
f(2) = 6+1
= 7
This is written in vertex form:-
y = a(x - b)^2 + c where (b, c) is the vertex.
Comparing the function in the question to the above:-
b = -2 and c = 0 so the vertex is at the point (-2, 0) answer
The y intercept occurs when x = 0 so here it is:-
-1.5( 0 + 2)^2 = -6
y intercept is at ( 0, -6) answer
