Answer:
The set of transformation would prove ΔEFG ~ ΔGHI is "Reflect ΔGHI
over x = −2, and dilate ΔG′H′I′ by a scale factor of 2 from point G" ⇒
last answer
Step-by-step explanation:
To solve this we need only substitute values of u and w, and then calculate.
<span>u+5v-w = 6 + 5v - 9 = 5v +6 - 9 = 5v - 3</span>
Im pretty sure the answer is a, sorry if its incorrect.
Answer:
(a) 25
(b) (5+4)*2 +6 -2*2 -1
(c) see below
Step-by-step explanation:
(a) evaluating exponents:
6*7 -9*9 +64
Evaluating products:
42 -81 +64
Evaluating sums:
-39 +64
25
__
(b) The last three terms of the expression sum to +1, and it is fairly easy to modify the first two terms to make one term that has a value of 18. Then the expression evaluates as 18+1 = 19.
(5+4)*2 +6 -2*2 -1
__
(c) Evaluating parentheses:
= 9*2 +6 -2*2 -1
Evaluating products:
= 18 +6 -4 -1
Evaluating sums (left to right):
= 24 -4 -1
= 20 -1
= 19
