2. Two numbers m and n have the following properties: (1) their sum is 26 and (2) n is five
more than twice m. Write a system of equations that models the two properties given (write
them with the word and between them).

3. Enter your math answer
Find the values of m and n by solving the system you wrote in question 2

Answers

Answer 1

Answer:

m + n = 26 and n = 2m + 5

m = 7, n = 19

Step-by-step explanation:

Because we know that the sum of m and n is 26, we get the first equation. For the second equation, we are told that n is five more than twice m. So we multiple m by 2 and then add 5 to that to get what n is. This is our second equation.

We plug the second equation in for n in the first equation to get

m + (2m + 5) = 26

3m + 5 = 26

3m = 21

m = 7

And then for n, we solve the first equation to get

7 + n = 26

n = 19

Answer:

9.y=Mx+b

   Y= 2/5x+4

10. y=Mx+b

     Y=4x-5

Step-by-step explanation:

Answer:

9) [tex]y=\frac{2}{5} x+4[/tex]

10) [tex]y=4x-5[/tex]

Step-by-step explanation:

Slope-intercept form is [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept, or the value of y when the line crosses the y-axis.

Question 9

[tex]y=mx+b[/tex]

The question tells us that the slope of the line is [tex]\frac{2}{5}[/tex]. Because the slope is [tex]m[/tex], plug [tex]\frac{2}{5}[/tex] into the equation as [tex]m[/tex].

[tex]y=\frac{2}{5} x+b[/tex]

Then, it tells us that the y-intercept is (0,4). Recall that the y-intercept is the value of y when the line crosses the y-axis. The value of y in the point (0,4) is 4. Because the y-intercept is [tex]b[/tex], plug 4 into the equation as [tex]b[/tex].

[tex]y=\frac{2}{5} x+4[/tex]

Question 10

[tex]y=mx+b[/tex]

First, we must calculate the slope using the slope equation:

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex] when the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

The given points are (0,-5) and (2,3). Plug those into the equation.

[tex]\frac{3-(-5)}{2-0}[/tex]

Two negatives make a positive

[tex]= \frac{3+5}{2-0}\\= \frac{8}{2} \\= 4[/tex]

Therefore, the slope of the line is 4. Plug 4 into the original equation as [tex]m[/tex].

[tex]y=4x+b[/tex]

Now, we can find the y-intercept by simply looking at the graph. The line crosses the y-axis at the point (0,-5). Therefore, the y-intercept is -5. Plug -5 into the equation as [tex]b[/tex].

[tex]y=4x+(-5)\\y=4x-5[/tex]

Use the simple interest formula to find the interest earned for $347 at 9.63% for 5 years

Answers

Answer:

$167.08

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 9.63%/100 = 0.0963 per year,

then, solving our equation

I = 347 × 0.0963 × 5 = 167.0805

I = $ 167.08

The simple interest accumulated

on a principal of $ 347.00

at a rate of 9.63% per year

for 5 years is $ 167.08.

Find the values of x and y.

Answers

Answer:

x = 67

y = 169

Step-by-step explanation:

We know that (x-1) + 52 + (y-7) = 180 because they're all on the same straight line. We also know that x-1 = 66, because they are alternate interior angles.

Solve for x:

x-1 = 66

x = 67

Now solve for y:

(67-1) + 52 + (y-7) = 180

y = 169

Find the slope-intercept form of the equation of the line which contains the points (-2, 5) and (3, 20).

Answers

Answer:

y = 3x - 11

Step-by-step explanation:

First, use the y2-y1/x2-x1 format to find the slope: 20 - 5/3 - (-2)

(Note: change 3 - (-2) to 3 + 2 to make it easier for you)

Simplify 15/5.

Your slope would be 3/1 or 3.

Now use the slope-intercept format: y = mx + b

(Use either the first point or second point, I chose the first)

5 = 3(-2) + b

Multiply 3 and -2, which is -6.Subtract 5 from -6: -6 - 5 = -11

Your y-intercept is -11.

Answer:

10/16 is not equivalent to ⅔.

⅛+¾=⅞

Step-by-step explanation:

To simplify to simplest form find the GCF for both and divide on each side.

[tex] \frac{10}{15} = \frac{2}{3} [/tex]

the GCF is 5, so you divide the numerator and denominator by 5 to get 2/3.

[tex] \frac{4}{6} = \frac{2}{3} [/tex]

When you divide the numerator and denominator by 2 (GCF) it would be ⅔.

[tex] \frac{12}{18} = \frac{2}{3} [/tex]

when you divide both the numerator and denominator by 6 (GCF) you get ⅔.

[tex] \frac{10}{16} = \frac{5}{8} [/tex]

when you divide the numerator and denominator by 2 (gcf) you get ⅝.

therefore, 10/16 is not equivalent.

[tex] \frac{1}{8} + \frac{3}{4} = [/tex]

Find the LCM

Least Common Multiple is 16.

8: 8, 16

4: 4, 8, 12, 16

[tex] \frac{2}{16} + \frac{12}{16} [/tex]

for ⅛ you multiply the numerator and denominator by 2 to get 2/16. do the same with 3/4 but with 4 to get 12/16

[tex] \frac{2}{16} + \frac{12}{16} = \frac{14}{16} [/tex]

you can simplify by dividinv both sides by 2 to get 7/8.

I owe $8500 on my credit card. The card has a promotional interest rate of 0% for 24 months. To repay the debt, I'm going to pay a fixed amount toward the balance every month.

(Select all that apply.)

Question 4 options:

D=6460+170t

Write the equation for a line that is parallel to the line y=-1/3x -4 and passes through the point (3, -1)​

Answers

Answer:

y = -1/3x

Step-by-step explanation:

Since the line has to be parallel, that means it will have the same slope. So, we use the given point and slop to solve for the new y= mx + b using the equation y - y = m( x - x)

m= -1/3    x = 3   y = -1

y + 1 = -1/3(x - 3)

y + 1 = -1/3x + 1

y = -1/3x
