nadezda [96]

Answer:

2

Step-by-step explanation:

Method- 56-25=31-25=6

I subtracted 25 until I cant no more so I only did it 2 times so 2 quarters are in the piggy bank.

Quarters-2

Then since the remainder was 6 that means there was only 1 penny and 1 nickel.

Pennies- 1

Nickels-1

WINSTONCH [101]

An expression is defined as a set of numbers, variables, and mathematical operations. The value of b for which the expression x² + bx + 18 can be factored is 9.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The value of b for which the given expression x² + bx + 18 can be factored is 9. This will make the expression factored as (x+3) and (x+6).

Thus, the value of b for which the expression x² + bx + 18 can be factored is 9.

Which is not an equation of the line that passes through the points (1, 1) and (5, 5)?
nydimaria [60]

Answer:

Any equation of the line that is different from y=x is the solution to the problem.

Step-by-step explanation:

step 1

Find the slope of the line that passes through the points (1, 1) and (5, 5)

m=(5-1)/(5-1)=1

step 2

Find the equation of the line into slope point form

y-y1=m(x-x1)

we have m=1

(x1,y1)=(1,1)

substitute

y-1=(1)(x-1)

y=x-1+1

y=x

therefore

Any equation of the line that is different from y=x is the solution to the problem.

U(x)=-2-2x+7 please help
Black_prince [1.1K]
<span>Simplifying u(x) = -2 + -2x + 7 Multiply u * x ux = -2 + -2x + 7 Reorder the terms: ux = -2 + 7 + -2x Combine like terms: -2 + 7 = 5 ux = 5 + -2x Solving ux = 5 + -2x Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Divide each side by 'x'. u = 5x-1 + -2 Simplifying u = 5x-1 + -2 Reorder the terms: u = -2 + 5x-1</span>
