It's saying that the polynomial can be factored into a perfect square (x + 5)(x+5) because when you multiply it, you get x² + 5x + 5x + 25 or x² + 10x + 25 so the factored form can be rewritten as (x + 5)² because it can be multiplied by itself to get the polynomial listed, so a = x and b = 5

Solve system by substitution x-5y=18 2×+6y=4

vfiekz [6]

Algebra Calculator
I will solve your equations by substitution.12y=4;x−5y=18
Step: Solve 12y=4for y:12y/12=4/12(Divide both sides by 12)y=13Step: Substitute 1/3 for y in x−5y=18:
x−5y=18
x−5(1/3)=18
x+−5/3=18(Simplify both sides of the equation)
x+−5/3+5/3=18+5/3(Add 5/3 to both sides)
x=59/3
Answer:x=59/3 and y=1/3

Shawn uses 45N of force to stop the cart 1 meter from running his foot over. How much work does he do?

zalisa [80]

Answer:

$\boxed {\boxed {\sf 45 \ Joules}}$

Step-by-step explanation:

Work can be found by multiplying the force by the distance traveled in the direction of the force.

$W=F*d$

The force is 45 Newtons.

The distance traveled is 1 meter.

$F=45 \ N \\d= 1 \ m$

Substitute the values into the formula.

$W=45 \ N * 1 \ m$

Multiply.

$W=45 \ N*m$

1 Newton meter is equal to 1 Joules.

Therefore our answer of 45 Newton meters is equal to 45 Joules.

$W= 45 \ J$

The work done is 45 Joules.

What does g(n) equal

NikAS [45]

We are given the function:
g(n) = $3 (\frac{7}{5} )^n$

We need to find what g(-3) equals.

What the question is asking is what is the resulting value after you plug in -3 as n to the function. Meaning you replace the n that is in the function with -3.

g(-3) = $3( \frac{7}{5})^{-3}$

Remember back to the order of operations.

Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

For this problem we can keep the fraction as it is (unless you are permitted to use a calculator... if that is the case then just plug all that into a calculator) and keep going to the exponent.

Negative exponents make fractions FLIP. So our fraction will look like this: $(\frac{7}{5})^{-3} = (\frac{5}{7})^{3}$

Now that we have it without the negative exponent we need to distribute the cubed power to each number in the fraction (which is essentially the same as saying this: $\frac{5}{7}* \frac{5}{7}* \frac{5}{7}$ )

$\frac{5^{3}}{7^{3}} = \frac{125}{343}$

We ARE NOT done! We still have this left:
g(-3) = $3 \frac{125}{343}$
Multiplying by 3 you get the following:

$\frac{375}{343}$

So what does g(-3) equal? This right here:

$\frac{375}{343}$
