Answer:y=2x+4
explanation:
−10x+5y=20
Step 1: Add 10x to both sides.
−10x+5y+10x=20+10x
5y=10x+20
Step 2: Divide both sides by 5.
5y=10x+20
5. 5
Y=2x+4
Answer: 81280
Step-by-step explanation:
From the question, we are informed that there are 635,000 residents in Jones County and 12.8% are under the age of 5.
The number of residents that are under the age of 5 will be calculated as:
= 12.8% × 635000
= 0.128 × 635000
= 81280
Answer:
Step-by-step explanation:
Keep in mind that we want to eliminate the radical from the denominator. Note that the denominator is equal to
8^(1/4) = (2^3)^(1/4).
If we multiply the entire given expression by 2^(1/4), we get:
2^(1/4) √10
----------- * -----------------
2^(1/4) (2^3)^(1/4)
or
2^(1/4) √10 2^(1/4) · √10 2^(1/4) · 10^(2/4)
----------- * ----------------- = ---------------------- = ---------------------------
2^(1/4) (2^3)^(1/4) 2^(1/4 + 3/4) 2
2^(1/4) · 10^(2/4) 2^(1/4) · 100^(1/4) 200^(1/4)
= ------------------------------ = -------------------------- = --------------------
2 2 2
This result is the same as the first answer choice:
fourth root of 200 over 2
36
+57
------
93
On a number line: Start at 0. Count forward until you reach 36. Once you've reached 36, Mark it. Then you go forward 57, from the mark you made at 36. You should end up on 93 on the number line.
Answer:
d. 18x^3-27x^2y
Step-by-step explanation:
(3x)^2(2x-3y)
work out the first term
9x^2(2x-3y)
distribute
18x^3-27x^2y
