Answer:0.64

Step-by-step explanation:

Answer:

The number is 62

Step-by-step explanation:

Let the digits of the number be T and U;

A 2 digit number is represented as: 10T + U

So,

[tex]T + U = 8[/tex]

[tex]10T + U - (10U + T) = 10 + 10U + T[/tex]

Required

Find the digit

Make U the subject in the first equation

[tex]U = 8 - T[/tex]

Substitute 8 - T for U in the second

[tex]10T + U - (10U + T) = 10 + 10U + T[/tex]

[tex]10T + 8 - T - (10*(8-T) + T) = 10 + 10(8 - T) + T[/tex]

[tex]10T + 8 - T - (80-10T + T) = 10 + 80 - 10T+ T[/tex]

[tex]10T + 8 - T -80+10T - T = 10 + 80 - 10T+ T[/tex]

Collect Like Terms

[tex]10T + 10T - T- T + 8 -80 = 10 + 80 - 10T+ T[/tex]

[tex]18T -72 = 90 - 9T[/tex]

[tex]9T + 18T = 90 + 72[/tex]

[tex]27T = 162[/tex]

[tex]T = 162/27[/tex]

[tex]T = 6[/tex]

Recall that:

[tex]U = 8 - T[/tex]

[tex]U = 8 - 6[/tex]

[tex]U = 2[/tex]

Hence, the number is 62

Answer:

y=1/2x - 7

Step-by-step explanation:

Since the lines are parallel, this means that the slopes will be the same, only the y-intercept will change. I graphed this out to find the answer.  

Answer:

the amount of each deposit is $45,555

Step-by-step explanation:

The computation of the each deposit is shown below:

Given that

Future value be $20,000

Time period = 15 × 2 = 30

And, the rate = 5% ÷ 2 = 2.5%

Now the formula is as follows

= (Future value × rate of interest) ÷ (1 + rate of interest)^time period - 1

= ($20,000 × 2.5) ÷ (1 + 0.025)^30 - 1

= $50,000 ÷ 1.0975675791

= $45,555

Hence, the amount of each deposit is $45,555

Answer:

If im correct im pretty sure its 6xy

The GCF of 18xy and 12xy is 6xy.

The largest factor that splits both numbers is said to be the greatest common factor. List the prime factors of each integer before calculating the greatest common factor.

18 and 24 share one 2 and one 3 in common.

, so 2 x 3 = 6 is the GCF of 18 and 24.

Given:

18xy and 12xy

now, factoring the above terms

18xy = 2 × 3 × 3 × x × y

12xy= 2 × 2 × 3 × x × y

So, 18xy & 12xy = 2 x 3 xy = 6xy

hence, the GCF of 18xy and 12xy is 6xy.

Answer:

the answer is 5:7

Step-by-step explanation:

as a fraction, the ratio looks like this:

1500/2100

where 1500 is the number of rolls with double prints and 2100 is the amount of rolls developed.

if you simplify the fraction, you get 5/7.

5/7 is 5:7 written as a ratio in this problem.

Answer:

y=6x-2

Step-by-step explanation:

The equation of the line is y=mx+b

FINDING SLOPE: To find the slope of a given line use the equation [tex]\frac{y2-y1}{x2-x1}[/tex]

So x1=-3, y1=-20 and x2=1, y2=4

Plug those numbers into the equation: [tex]\frac{4-(-20)}{1-(-3)}[/tex]  and we get the slope which is 6.

FINDING Y-INTERCEPT: Then we find the y intercept by plugging in our points (you can choose) I will use (1,4) and solve.

y=6x+b

4=6(1)+b

b=-2

Answer:

Read left to right

Do parenthesis first

-4 ( 1 + 5) ^2

-4 (6) ^2

Then exponent

6^2 = 6 x 6 = 36

-4 x 36 = -144

Then divide

-144 / 6 = -24

Then the next parenthesis

(42+5) = 47

-24 - 47 = -71

Step-by-step explanation:

Answer:

Part A)

The slope is 3.

Part B)

[tex]\displaystyle y-1=3(x+3)[/tex]

Part C)

[tex]\displaystyle y=3x+10[/tex]

Step-by-step explanation:

We know that the line goes through the points (-3, 1) and (-2, 4).

Part A)

To find the slope of a line given two points, we can use the slope formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Where (x₁, y₁) and (x₂, y₂) are our two points.

So, let’s let (-3, 1) be (x₁, y₁) and let (-2, 4) be (x₂, y₂). Substitute appropriately:

[tex]\displaystyle m=\frac{4-1}{-2-(-3)}[/tex]

Evaluate:

[tex]\displaystyle m=\frac{3}{-2+3}=\frac{3}{1}=3[/tex]

Hence, the slope of our line is 3.

Part B)

Point-slope form is given by:

[tex]\displaystyle y-y_1=m(x-x_1)[/tex]

Where m is our slope and (x₁, y₁) is a point.

So, let’s substitute 3 for m.

For our point, we can use either of the two given. Let’s use (-3, 1) for consistency. So, let (-3, 1) be (x₁, y₁). Therefore:

[tex]\displaystyle y-1=3(x-(-3))[/tex]

Simplify. Hence, our point-slope form is:

[tex]\displaystyle y-1=3(x+3)[/tex]

Part C)

To rewrite into slope-intercept form, we can just solve for y from our point-slope form. So, we have:

[tex]\displaystyle y-1=3(x+3)[/tex]

Distribute on the right:

[tex]\displaystyle y-1=3x+9[/tex]

Add 1 to boths sides. So, our slope-intercept equation is:

[tex]\displaystyle y=3x+10[/tex]

Answer:-6x^3y^4+8x^2y^2

Step-by-step explanation:

Given:

Rita covered 1 mile in 15 minutes.

She covered 3 miles in 30 minutes.

To find:

The rate at which she is riding.

Solution:

Let y be the number of miles covered in x minutes.

Rita covered 1 mile in 15 minutes. So, the point is (15,1).

She covered 3 miles in 30 minutes. So, the point is (30,3).

Slope of the line:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{3-1}{30-15}[/tex]

[tex]m=\dfrac{2}{15}[/tex]

Therefore, she is riding [tex]\dfrac{2}{15}[/tex] miles per minute.

Answer:

y=mx+b

Step-by-step explanation:

Answer:

y=mx+b

Explanation:

The slope-intercept formula is y=mx+b. The b represents the y-intercept, which is the point where a line on a graph meets the y-axis. The coordinates for this would be (0,b). The m represents the slope, which is the rate of change. The x represents any x variable that you plug in. The y represents the y variable.
