Answer:
In the last task, the result is 17+3x/6
Step-by-step explanation:
X+5/3 - 2x-7/6 + x/2
2(x+5)-(2x-7)+3x <em>/</em><em>6</em>
2x+10-2x+7+3x <em>/</em><em>6</em>
17+3x/6
I dunno this task above, I hope this one is correct :))
What is it that we need to find?
-3(-4y+3)+7y
First multiply -3 by the terms in the parentheses
-3(-4y+3) = 12y -9
Your expression now looks like
12y -9 +7y
Then combine the terms containing the variable y
12y + 7y = 19 y
Your final answer is
19y - 9 (answer choice A)
Answer:
-3
Step-by-step explanation:
4x + 25 = 13 ➡ 4x = 13 - 25 ➡x = -3
Answer: Choice B
y = (x+3)^2 - 1
==================================================
Recall that vertex form is y = a(x-h)^2 + k with the vertex being (h,k)
From the given graph, it shows that (h,k) = (-3,1) is the vertex. So we plug this pair of values into the general function above to get
y = a(x-h)^2 + k
y = 1(x-(-3))^2 + (-1)
y = (x+3)^2 - 1
which is the final answer
note: a = 1 is the case for all four answer choices, so we don't have to worry about the value of 'a'
