Answer:
y = 2x - 3
Step-by-step explanation:
x + 2y = 4
2y = -x + 4
y = -1/2x + 2
1 = 2(2) + b
1 = 4 + b
-3 = b
y = 2x - 3
Answer:
True
Step-by-step explanation:
We can sue the pythagorean theorem to verify. 15^2+36^2 should equal the longest side squared or 39^2. If we plug in the numbers, it checks out!
Answer:
Joe is 14.
Martha is 28.
Step-by-step explanation:
Use the variables and information from the question to make equations.
If Joe's age is half Martha's:
(1/2)m = j OR 2j = m
If their ages combined is 42:
m + j = 42
We can substitute the equation m=2j into equation m + j = 42, replacing "m".
m + j = 42 Substitute m for 2j
2j + j = 42 Combine like terms, terms with same varables
3j = 42 Divide both sides by 3 to isolate j
j = 14 Joe's age
Since j = 14, we can substitute it into equation m=2j to find "m".
m = 2j Substitute j for 14
m = 2(14) Simplify
m = 28 Martha's age
Therefore Joe is 14 and Martha is 28.
The correct answer is D. k= 3
Explain
First , point ( x,y) by factor k
It will become (x/k,y)
The vertex is (-3,-3) of f(x)
And the other vertex is (-1,-3) of g(x)
-1,-3)= (-3/3 ,3)
So the dilation factor is 3
(-1,-3) = (-3 x 1/3 ,3)
Factor is k
g(x)= f(1/3 x)
So k = 3
Because the graph have shrunk f(x) by factor 3
I Hope this make sense to you
Glad I can help you :D
