Part 1
<h3>Answer: 13</h3>
---------------------
Explanation:
We'll replace every copy of x with -3. Then use PEMDAS to simplify.
f(x) = -2x+7
f(-3) = -2(-3)+7
f(-3) = 6+7
f(-3) = 13
===========================================================
Part 2
<h3>Answer: -11</h3>
---------------------
Explanation:
We work backwards in a sense compared to what part 1 did. Instead of finding f(x) based on x, we determine what x must be for a given f(x).
We'll replace f(x) with 29 and solve for x like so
f(x) = -2x+7
29 = -2x+7
-2x+7 = 29
-2x = 29-7
-2x = 22
x = 22/(-2)
x = -11
Note how if you replaced x with -11, we'd get,
f(x) = -2x+7
f(-11) = -2(-11)+7
f(-11) = 22+7
f(-11) = 29
which helps confirm we have the correct answer.
Answer:
1. The product of thirty and eight more than fifty-two.
2. Thirty times the sum of eight and fifty-two
Step-by-step explanation:
1) 52+8 (eight more the fifty-two )
52+8 (The product of thirty and eight more than fifty-two.)
2) 52+8 (The sum of eight and fifty-two)
52+8 (Thirty times the sum of eight and fifty-two)
I converted the four months into a fraction, and got 1/3. There's 12 months in a year, and divided by 4, I got 3.
Answer:
3.5 inches
Step-by-step explanation:
We can rotate the figure to the left 90 degrees clockwise so that it becomes same orientation as the figure to the right.
Since they are similar figures, their corresponding sides are proportional.
The 4 inch side of left figure corresponds to 16 in side of right side figure.
The "?" inch side of left figure corresponds to 14 in side of right side figure.
We can replace "?" with "x" and setup two ratios and equate them:
Now, we can cross multiply and solve for x:
Hence,
the unknown side marked "?" is equal to 3.5 inches
