For the value of x,

And for value of y,

[tex]9x + 3y = 15 \\ = > 3y = 15 - 9x \\ = > y = \frac{15 - 9x}{3} \\ = > y = \frac{3(5 - 3x)}{3} \\ = > y = 5 - 3x \: \: \: or \: \: \: \\ y = - 3x + 5[/tex]

Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Milan has been adding money. Write an
equation relating S to W. Then use this equation to find the total amount of money in the savings account after 17 weeks.

Answers

Answer:

Milan will have $1,370 in the account after 17 weeks.

Step-by-step explanation:

a waterslide has an angle of elevation of 20 degrees whats is the rise for a run of 2.6 m?

Answers

Answer:

Therefore, the rise will be 0.95 m

Step-by-step explanation:

As the waterslide has an angle of elevation of 20 degrees.

Ф = 20°

And we have to determine the rise for a run of 2.6 m.

All we need is to use the trigonometric ratio of tan Ф

Because

tan Ф = rise/run

As

run = 2.6 m

Ф = 20°

so

tan Ф = rise/run

tan (20) = rise/run

rise = tan (20) × 2.6

rise = 0.95 m

Therefore, the rise will be 0.95 m

what is the y-intercept of (5,8) and (12,36)

Answers

Answer:

The y intercept is (0,-12)

Step-by-step explanation:

You use the slope formula and the slope-intercept form to find the slope m and then the y intercept b.

Answer:

(0, -12)

Step-by-step explanation:

In order to find the y-intercept of the equation y = mx + b ( where m is the slope and b is the y-intercept), we first have to find the slope. We can do this by using the two points given to us.

To find the slope:

The slope is equal to: [tex]\frac{y2 - y1}{x2 - x1}[/tex]

Let's plug (5,8) and (12,36) into the equation:

[tex]\frac{36 - 8}{12 - 5}[/tex]

Now let's solve for the slope:

36 -8 = 28

12 - 5 = 7

So we get: [tex]\frac{28}{7}[/tex]

Now that we've found the value of the slope, we can put it into the equation:

y = [tex]\frac{28}{7}[/tex]x + b

To find the value of b, we can input the values of one of the given points into the equation and solve for b. Let's use (5,8):

Input the values of x and y into the equation:  8 = [tex]\frac{28}{7}[/tex](5) + b

Multiple [tex]\frac{28}{7}[/tex] by 5:  8 = [tex]\frac{140}{7}[/tex] + b

Divide 140 by 7:  8 = 20 + b

Subtract 20 from both sides of the equation to isolate b:  

8 - 20 = 20 - 20 + b

-12 = b

The y-intercept is (0, -12).

Write the polynomial form given the leading coefficient
and the zeros of the function.
1. Leading coefficient: -1; roots: 1, 1+73, 1 - 3

someone help please

Answers

Answer:

For a polynomial of any degree, with roots x₁, x₂, ...., xₙ and a leading coefficient A, we can write it as:

p(x) = A*(x - x₁)*(x - x₂)*...*(x - xₙ)

In this case, we have:

Leading coefficient = -1

Roots : 1, 1 + 73, 1 - 3

Then the polynomial will be:

p(x) = -1*(x - 1)*(x - (1 + 73))*(x - (1 - 3))

      = -1*(x - 1)*(x - 74)*(x + 2)

Now, if the roots are:

1, 1 + 73*i, 1 - 3*i

then:

p(x) = -1*(x - 1)*(x - 1 - 73*i)*(x - 1 + 3*i)

Suppose an artist is working on a painting. On Monday, he painted 1/2 of it. On Tuesday, he completed another 1/3 of the painting. What percent of the painting has yet to be done? Round your answer to the nearest whole percent.

Answers

Answer:

about 83%

Why:

1/3 + 1/2 = 0.83333333333

0.83333333333 as a percentage is 83.333333333%

Answer:

17%

Step-by-step explanation:

He completed 1/2 plus 1/3 of the painting.

The total he completed is

1/2 + 1/3 = 3/6 + 2/6 = 5/6

He needs to to 1 - 5/6 = 6/6 - 5/6 = 1/6 of the painting.

100% is the whole. He needs to do 1/6 of 100%.

1/6 * 100% = 100%/6 = 16.666...%

Anthony earned $131 in tips last night while working at the restaurant. If his tips consisted of $1 bills and $5 bills only and he counted 47 bills in total, then how many $5 bills did Anthony receive?

Answers

Answer:

21

Step-by-step explanation:

Let x = $1 bill

Let y = $5bill

Translating the word problem into an algebraic equation;

For the total number of bills;

[tex] x + y = 47[/tex] .........equation 1

For the total number of tips;

[tex] x + 5y = 131[/tex] ..........equation 2

*Solving the linear equation by using the substitution method*

Making x the subject in equation 1:

[tex] x = 47 - y[/tex] .......equation 3

Substituting "x" into equation 2;

[tex] (47 - y) + 5y = 131 [/tex]

Simplifying the equation, we have;

[tex] 47 + 4y = 131 [/tex]

[tex] 4y = 131 - 47 [/tex]

[tex] 4y = 84 [/tex]

[tex] y = \frac {84}{4} [/tex]

y = 21 (For the $5 bills).

Therefore, Anthony received 21 pieces of the $5 bills.

To find x;

Substituting "y" into equation 3;

[tex] x = 47 - 21[/tex]

x = 26 (For the $1 bill).

The length of each of the two congruent sides of an isosceles triangle is 3x - 1. The length of the third side is 2x + 1. The perimeter is 55 feet. Which equation does NOT represent the perimeter?

8x - 1 = 55

6x - 2 + 2x + 1 = 55

2 (3x - 1 + 2x + 1) = 55

2 (3x - 1) + (2x + 1) = 55

Answers

Answer: The third choice

Explanation:

This equation does not represent the perimeter.

To write the equation:

2(3x - 1) + (2x + 1) = 55
6x - 2 + 2x + 1 = 55
8x - 1 = 55

Thus, 3 of the choice represent but the the third choice didn’t appear in the equation.
