Answer:

y = -4

Step-by-step explanation:

5 - 7y = 33   {Subtract 4 form both sides}

   -7y = 33 -5  

     -7y = 28          {Divide both sides by (-7)

        y = 28/-7

        y = -4

Answer:

y=-4

Step-by-step explanation:

-7y=33-5

-7y=28

y=28÷-7

y=-4

Answer: 109

Step-by-step explanation: 327/3 =109

Answer: 109

Step-by-step explanation:

Look at the lowest point of the line ( the bottom of the u)

On f(x) the u is at the point (0,0)

On g(x) the u is at point ( -3,4)

This means it shifted to the left 3 units and up 4 units.

The answer is left 3, up 4

Answer:

A. left 3, up 4

Step-by-step explanation:

Answer:

n=-4/3

Step-by-step explanation:

So the equation is -2/3n+7=15

First you subtract 7 from both sides: -2/3n+7-7=15-7 : -2/3n=8

Next multiply by 1/-2 on both sides, canceling out the -2 on the left and dividing 8 by -2 on the right: 3n=-4

Next divide by 3 on both sides

Answer: n=-4/3

Step-by-step explanation:

You can use the simple interest formula here: I(interest)=P(principal amount)r(interest rate)t(years). I=Prt. So just plug in the numbers. I=90x.15x1=13.5

Answer:

(-5, -1)

Step-by-step explanation:

When two lines intersect, their x and y values are equal. So,

x = 3y - 2 must equal -7 - 2y = x

x = 3y - 2 = -7 - 2y = x

Let's look at the two middle equations and solve for y.

3y - 2 = -7 - 2y

Add 2y to both sides

5y - 2 = -7

Add 2 to both sides.

5y = -5

y = -1

Now, let's find x. You can use either equation for this step.

When y = -1, then 3y - 2 =

(3)(-1) - 2 = -3 - 2 = -5

So, x = -5, and y = -1

Thus, the answer is (-5, -1)

Answer:

the answer is going to be 203 square inches

Step-by-step explanation:

7 x 11 = 77

77 x 2 = 154

7 x 7 = 49

154 + 49 = 203

NOTICE:11.5 is useless, don't get tricked.

Answer:

Solution given:

side of base[a]=7in

height[h]=11in

slant height [l]=11.5in

THE TOTAL SURFACE AREA OF THE SQUARE PYRAMID=a²+2ah=7²+2*7*11=203in²

The total surface area of square pyramid is 203in².

Answer:

Yes , i agree with Noah that the equation would be 3(x + 7) = 57

Step-by-step explanation:

P.S - The exact question is -

To find  - Noah writes the equation 3 (x+7)=57 to represent the situation.

               DO YOU agree with him? Explain your answer.

Proof -

Yes , i agree with Noah

Because in the figure we can see that there is x written 3 times and 7 written 3 time and whole the values is equal to 57 .

Because 57 is divided into x 7 x 7 x 7

∴ we can write it as

3 times x + 3 times 7 = 57

⇒3(x) + 3(7) = 57

⇒3(x+7) = 57

Ans Noah give the same equation 3 (x+7)=57

So, I agree with Noah.

What is the importance of polynomial functions?

Polynomials are an important part of the "language" of mathematics and algebra. They are used in nearly every field of mathematics to express numbers as a result of mathematical operations. Polynomials are also "building blocks" in other types of mathematical expressions, such as rational expressions.

How these real-life applications improve or contribute to the value of life?

Since polynomials are used to describe curves of various types, people use them in the real world to graph curves. Combinations of polynomial functions are sometimes used in economics to do cost analyses, for example. Engineers use polynomials to graph the curves of roller coasters and bridges.
