Which equation has no solution?
A.
4x - 9 = - 9
B.
x + 3x = 8x - 4x
C.
2x + 4 = 2x + 6
D.
3x + 2 = 17
2(3x + 1)-3(x + 2) = 2
Answer:
Step-by-step explanation:
2(3x+1)-3(x+2)
or,6x+2-3x+6=2
or,6x-3x=6-2+2
or,3x=6
or,x=2

At the sandwich shop, there is a sale each afternoon. A customer has a choice of
three types of bread and five different meats. Use the Fundamental Counting
Principle to determine how many combinations a customer can create ?
Answer:
15 combinations
Step-by-step explanation:
The fundamental counting principle states that if there are p ways to do one thing, and q ways to do another thing, then there are p×q ways to do both things. This means we need to multiply 3 by 5 to get the possible amount of combinations. This gets us 15. This means there are 15 combinations of bread and meat.
What are the possible degrees for the polynomial function? Help
Answer:
It is option 2 "even degrees of 6 or greater
Step-by-step explanation:
Write the equation of the function g(x) if g(x) = f(x - 3) +1 and f(x) = x3 + 1.
Answer:
Solution,
f(x) = [tex]x^{3}[/tex] + 1
Put x = x - 3,
f(x - 3) = [tex](x-3)^{3}[/tex] + 1
Now,
g(x) = f(x - 3) + 1
or, g(x) =[ [tex](x-3)^{3}[/tex] +1 ] + 1
or, g(x) = [tex]x^{3} -9x^{2} + 27x - 1 + 1+1[/tex]
or, g(x) = [tex]x^{3} - 9x^{2} +27x + 1[/tex]
Choose an equivalent ratio. 4:9
A) 27:40
B) 27:18
C) 12:27
D) 16:27
Answer:
The answer is C.
Step-by-step explanation:
The answer is C because both numbers in 4:9 can be multiplied by the same factor (3) to get 12:27, the answer. No other choice works because they require two different number factors, not just one, which means they aren't equivalent ratios to 4:9.
oh here you go theres the question
Answer:
in the first step you were supposed to multiply 3 and two not subrtract 5 and 3 because you have to multiply first according to P.E.M.D.A.S.
Step-by-step explanation:
Answer:
In the second step, the student did not complete the right steps in the right order.
Step-by-step explanation:
You should always complete equations using PEMDAS...Parenthesis, exponents, multiplication, division, addition, subtraction. The equation should look like this...
6*6 + 5 - 3 * 2
36 + 5 - 6
41 - 6

describe the transformation of the function f(x)=1/2x-2 that makes the slope two and the Y intercept -8
Answer:
Reflect over the axis of y=x-4
Step-by-step explanation:
f(x)=1/2x-2
g(x)=2x-8
axis of reflection: y=x-4

Which statements are true? Select MORE THAN ONE correct answer.
The absolute value of −9 is positive.
Since −9 is 9 units to the left of 0, ∣∣−9∣∣=−9 .
−9 is farther to the right on the number line than −10 , so ∣∣−9∣∣>|−10| .
The absolute value of −9 is equal to the absolute value of 9.

Noah was assigned to make 64 cookies for the bake sale. He made 25% MORE than that. How many cookies did Noah make? Explain how you got your answer.
PLEASE HELP MEH! WILL MARK BRAINLIEST!! DUE TODAY
Answer:
8 cookies were left after the bake sale. 72 were sold.
Step-by-step explanation:
64*1.25= 80
80*.9= 72
8
125% of 64 is equal to 80.
90% of 80 is equal to 72.
The number left was 10% of the number he made. The number he made was 125% of 64, so the number left was 8
10% × 125% × 64 = 0.125 × 64 = 8
