Answer:
the answer would be x=3
Step-by-step explanation:
the lines the have 1 line across it equal the same. same for the ones with 2. for example AB has one line across so it also equals CD because it has one line across (in the little octagonal shape). BC has two lines and so does AH so BC=AH
Answer:
C. log 10m is the correct answer.
Step-by-step explanation:
The laws of logarithm states that if you have:
So, comparing that to your question,
Answer:
m(c(a)) = 4.8875a can be used to find the marked-up price of a marble countertop depending on the area
Step-by-step explanation:
We are given that The cost for the raw materials of marble countertops, C s can be represented by the function c(a) = 4.25a --------1
a = area of the countertops.
we are also given that The retail markup, m, can be represented by the function m(c) = 1.15c.
We are supposed to find function can be used to find the marked-up price of a marble countertop depending on the area?
Marked up price function : m(c) = 1.15c.
Substitute the value of c form 1
Marked up price function of a marble countertop depending on the area:
m(c(a))=1.15(4.25 a)
m(c(a))= 4.8875 a
So, Option 1 is true
Hence m(c(a)) = 4.8875a can be used to find the marked-up price of a marble countertop depending on the area
<h3><u>
The equation is true.</u></h3>
10x + 5 = 8x + 2
<em><u>Subtract 5 from both sides.</u></em>
10x = 8x - 3
<em><u>Subtract 8x from both sides.</u></em>
2x = -3
<em><u>Subtract both sides by 2.</u></em>
x = -1.5
Because we are able to get a value for x, we know that the equation is true, as we can plug the value of x back into the original equation to verify.
10(-1.5) + 5 = 8(-1.5) + 2
-15 + 5 = -12 + 2
-10 = -10 √ this equation is true.
