Answer:
2b - 15
Step-by-step explanation:
b - 7 + b - 8
You combined the two b's correctly, but didn't combine the two constants, -7 and -8.
Those combine to -7 + (-8) = -7 - 8 = -15, so the final answer is
2b - 15
you have -7 and are subtracting 8 more, so you are moving 8 units left on the number line, so it has to get more negative.
Answer:
j=12
Step-by-step explanation:
j+7=19
j+7−7=19−7
j=12
answer:j=12
Answer:
around 4.1
Step-by-step explanation:
Using Pythaogrean theorem we get <em>sqrt 32</em> or <em>4sqrt2 </em>for the diagonal of the square.
To get x we can use Pythagorean theorem again to set up an equation,
32 + x^2 = 49
This gives us x = <em>sqrt17,</em> which is approximately 4.1231 or around 4.1
84,000 in standard form is 8.4 x 10^4
Using the stated transformation, the graph of g(2x) is given at the end of the answer.
<h3>Horizontal stretch and compression</h3>
An horizontal stretch or an horizontal compression happens when a constant is multiplied at the domain of the function, as follows:
g(x) = f(ax).
The definition of stretch or compression depends on the value of the constant a, as follows:
- If a > 1, it is a compression by a factor of 1/a.
- If a < 1, it is a stretch by a factor of 1/a.
In this problem, the rule is:
f(x) = g(2x).
Meaning that f(x) is an horizontal compression by a factor of 1/2 of g(x), and then the vertices are given as follows:
That is, in each vertex, the x-coordinate was divided by 2, and thus the graph with these vertices is given at the end of the answer.
