Answer 1

Answer:

slope=-3

y-intercept=-4

Step-by-step explanation:

slope= change in y/changes in x

pick any 2 co-ordinates (i'm using (-3,5) and (-1, -1))

5--1/-3--1=6/-2=-3

substitute that into the equation y=mx+c with m being the slope

y=-3x+c

-7=-3+c

c=-4

y intercept=-4

Chloe deposits $2,000 in a money market account. The bank offers a simple interest rate of 1.2%. How much interest will she earn in 10 years

Answers

Answer:

$240.00

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 1.2%/100 = 0.012 per year,

then, solving our equation

I = 2000 × 0.012 × 10 = 240

I = $ 240.00

The simple interest accumulated

on a principal of $ 2,000.00

at a rate of 1.2% per year

for 10 years is $ 240.00.

A doormat has an area of 223 square feet. 23 of the mat is green. What is the area of the green part of the doormat?

Answers

The area of the mat is the amount of space it occupies

The area of the green part of the doormat is 148.67 square feet

How to determine the area

The given parameters are:

Area = 223 square feet

Green = 2/3 of the total area

The area of the green part is the product of the proportion of the green part by the area of mat

So, we have:

[tex]Green = \frac 23 * 223[/tex]

Evaluate the product

Green = 148.67

Hence, the area of the green part of the doormat is 148.67 square feet

Answers

The correct first step to solving the system of equations in the most efficient manner is x = -4y +19.

The given system of equations is;

[tex]\rm 3 x + 2 y = 17\\\\x + 4 y = 19[/tex]

What is the first step to solving an equation?

The first step would be to rearrange the variables in the second equation so we have a defined expression for x.

We would want to do this so we could then plug in the defined expression for x into the other equation and solve for the other variable.

x + 4y = 19

Rearrange this by getting the 4y to the other side.

We can get 4y on the other side by subtracting 4y from both sides

x + 4y - 4y = 19 - 4y

x = -4y + 19

Hence, the correct first step to solving the system of equations in the most efficient manner is x = -4y +19.

The answer is y = 1/3x + 4. -3x repricdal = 1/3. 4=1/3(0) + 4

Answer:

y=1/3x+4

Step-by-step explanation:

y=2-3x is equivilent to y=-3x+2

Here were see that the coefficient of x is -3. In order to find a line that is perpendicular to another line, we need to put the opposite sign and make the coefficient the reciprical.

So now we know that y=1/3x will be perpendicular to your line. If the point goes through (0,4) that means when x is zero, y is 4. If we plug that into our expression 4=1/3*0, we see that we need to add 4 to make this true.

So our answer is y=1/3x+4

prove by induction that 7^2n+1 +1 is divisible by 8, for all nEN

Answers

Answer:

See below.

Step-by-step explanation:

Base case:

Replace n with 1.

7^(2×1+1)+1

7^3+1

343+1

344

8 is a factor of 344 since 344=8(43).

Induction hypothesis:

Assume there is some integer n such that 7^(2k+1)+1=8n for positive integer k.

7^(2[k+1]+1)+1

7^(2k+3)+1

7^(2k+1+2)+1

7^(2k+1)7^2+1

49×7^(2k+1)+1

Induction step:

49×(8n-1)+1

49(8n)-49+1

49(8n)-48

8[49n-6]

This means 8 is a factor of 7^(2(k+1)+1)+1.

Thus, this proves for all positive integer n that 8 is a factor of 7^(2n+1)+1.

During the New Year Festive Bonanza, the price of a jacket was reduced by 30%. Find the original price of the jacket when it cost $280 in the sale.

Answers

Answer:

$400

Step-by-step explanation:

The original price of the jacket = 100%

If the jacket was reduced by 30%, then the discounted price of the jacket = 100% - 30% = 70%

Therefore, $280 = 70% of the original price.

70% = 70/100 as a ratio

Using ratios, and letting [tex]x[/tex] be the original price:

                                          280/[tex]x[/tex] = 70/100

Cross multiply:           280 x 100 = 70 x [tex]x[/tex]

                                        28000 = 70[tex]x[/tex]

Divide both sides by 70:     400 = [tex]x[/tex]

Therefore, the original price of the jacket is $400

Alternatively, divide 280 by 70 to get the cost per 1%.  Then multiply this by 100 to get the original price (100%):

(280 ÷ 70) x 100 = 400

Describe the relationship among the lengths of the segments formed by the two secants. You may use words and/or an equation.
Suppose CG=4 in., CH=5 in. and GE=6 in. Is it possible to find the length of DH? If so, show how to find the length. If not, explain why not.

Answers

It is possible to find DH based on the stated theorem

Secant-secant rule:

This rule states that if two secants are drawn from an external point to a circle, then the product of the measures of one secant's external part and that entire secant is equal to the product of the measures of the other secant's external part and that entire secant.

Mathematically:

(CG+GE)CG = (CH+HD)CH

Given the following parameters

CG=4 in

CH=5 in

GE=6 in

Substitute to check if we can find DH

(4+6)*4 = (5+DH)*5

10*4 = 25 + 5DH

40 - 25 = 5DH

15 = 5DH
DH = 3in

Therefore it is possible to find DH based on the stated theorem

One interior angle of a regular polygon is 175 degrees. What is the measure of one exterior angle? Step by step (please answer)

Answers

Answer:

Exterior angle = 185°

Step-by-step explanation:

We know that:

Interior angle = 175°Total = 360°

Solution:

Exterior angle = 360 - 175=> Exterior angle = 185°

Hence, the measure of an exterior angle is 185°.

Answer:

Step-by-step explanation:

Solution 1

Interior angle equation of the n-sided polygon:

180°(n - 2)

Since each interior angle is 175, their sum is:

180°(n - 2) = 175°n180n - 360 = 175n5n = 360n = 72

The polygon has 72 sides.

We know the sum of exterior angles of a polygon is 360.

Find the measure of each exterior angle:

360°/72  = 5°Solution 2

The sum of interior and exterior angles is 180.

Find the value of the exterior angle:

180° - 175° = 5°
