Answer: y = -220
Step-by-step explanation:
y/11 ÷ 2= -10
To find the value of y
Rewrite the equation as y/11 ÷ 2/1 = -10
y/11 × 1/2 = - 10
y/22 = -10
Multiply each side by 22 to get the value of y
y= -10 × 22
y= -220
Check:
Slot the value of y into the equation
-220/11 ÷ 2 = -10
-20 ÷2 = -10

Answer:
D (assuming f(x)=-3x^2+4x+6)
Step-by-step explanation:
Let's find f(2) and f(3).
I'm going to make the assumption you meant f(x)=-3x^2+4x+6 (please correct if this is not the function you had).
f(2) means replace x with 2.
f(2)=-3(2)^2+4(2)+6
Use pemdas to simplify: -3(4)+4(2)+6=-12+8+6=-4+6=2.
So f(2)=2
f(3) means replace x with 3.
f(3)=-3(3)^2+4(3)+6
Use pemdas to simplify: -3(9)+4(3)+6=-27+12+6=-15+6=-9
So f(3)=-9
-9 is smaller than 2 is the same as saying f(3) is smaller than f(2) or that f(2) is bigger than f(3).
Answer:
A piece of carrot cake is $4
Step-by-step explanation:
Set this up as an equation.
Let’s have “c” represent cheese cake
And “p” represent pie.
4c+p=18
7c+3p=34
I would solve this using substitution because you already have one “p” in the top equation.
Subtract the 4c and move it to the other side.
p=18-4c
Now plug the equation above into your other equation
7c+3(18-4c)=34
Distribute the 3 into 18-4c
7c+54-12c=34
Combine like terms.
54-5c=34
Subtract 54 to both sides
-5c=-20
Divide -5 to both sides
C=4
A piece of carrot cake is $4
That seems like a pretty hard question
