A) f(x)=0.2x
B)f(12)=0.2(12)=2.4 dollars
The domain is the numbers you can use for x
so the domain is 4
the range is the possible y values we get from that domain
we get all real numbers because it goes up and down infinitey
domain is 4
range is all real numbers
Answer:
1/3
Step-by-step explanation:
When working with balanced expressions (stuff on both sides of the equal sign), "what you do to one side, you do to the other", which keeps it balanced.
The first thing we notice is the exponent 1/4, which is one both sides, so we can get rid of it on both sides by using the <u>reverse operation</u>.
The reverse of exponents is <u>square root</u>.
Isolate x to solve. Separate the variables and non-variables.
4x + 10 = 9 + 7x
4x - 4x + 10 = 9 + 7x - 4x Subtract 4x from both sides
10 = 9 + 3x
10 - 9 = 9 - 9 + 3x Subtract 9 from both sides
1 = 3x Divide both sides by 3 to isolate x
x = 1/3 Answer
Answer:
1⅚
Step-by-step explanation:
(3 + ⅔) ÷ 2
11/3 ÷ 2
11/3 × 1/2
11/6
1⅚
Answer: It would be area, because it involves multiplying length by width, therefore covering the inside
