What is the answer to -3x+2y=5
3x+y=7

Answer:

Step-by-step explanation:

To find out how many miles you are going per minute you would find the unit rate. The unit rate is 3.6

You are going at 3.6 minutes per mile.

So you would multiply 3.6 by 7 to get 25.2 minutes.

Final answer:

The x-intercept of the line 5x - y = 10 is (2, 0), the y-intercept of the line 9x + 3y = -18 is (0, -6), and the equation 6x - 4y = -12 has an x-intercept at (-2, 0) and a y-intercept at (0, 3).

Explanation:

To find the x-intercept of a line, we set the value of y to zero and solve for x. For the equation 5x - y = 10, we set y to 0:

5x - (0) = 10

5x = 10

x = 2

The x-intercept is therefore the point (2, 0).

To find the y-intercept of a line, we set the value of x to zero and solve for y. For the equation 9x + 3y = -18, we set x to 0:

(0) + 3y = -18

3y = -18

y = -6

The y-intercept is therefore the point (0, -6).

For the equation 6x - 4y = -12, the x-intercept and y-intercept can be found similarly. Let's start with the x-intercept. Set y to 0:

6x - (0) = -12

6x = -12

x = -2

The x-intercept is the point (-2, 0). Now, for the y-intercept, we set x to 0:

(0) - 4y = -12

-4y = -12

y = 3

The y-intercept is the point (0, 3). Thus, for 6x - 4y = -12, the intercepts are x = -2 and y = 3.

Answer:

C) They are perpendicular lines.

Step-by-step explanation:

We first need to find the slope of the graph of the lines passing through these points using:

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

The slope of the line that passes through (−12, 15) and (4, −5) is

[tex] m_{1} = \frac{ - 5 - 15}{4 - - 12} [/tex]

[tex]m_{1} = \frac{ - 20}{16} = - \frac{5}{4} [/tex]

The slope of the line going through (−8, −9) and (16, 21) is

[tex] m_{2} = \frac{21 - - 9}{16 - - 8} [/tex]

[tex] m_{2} = \frac{21 + 9}{16 + 8} [/tex]

[tex]m_{2} = \frac{30}{24} = \frac{5}{4} [/tex]

The product of the two slopes is

[tex]m_{1} \times m_{2} = - \frac{4}{5} \times \frac{5}{4} = - 1[/tex]

Since

[tex]m_{1} \times m_{2} = - 1[/tex]

the two lines are perpendicular.

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. The number 3.636408 to the nearest ten-thousandth will be 3.636.

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.

The given decimal number 3.636408 can be written to the nearest ten-thousandth with the help of a number line. The two of the closest number to 3.636408 are 3.636 and 3.637.

Now, as it can be observed that the distance between 3.636408 and 3.636 is less than 3.636408 and 3.637.

Therefore, the number 3.636408 to the nearest ten-thousandth will be 3.636.

Since the ratio of girls and boys must be the same in each team, and all the competitors must be involved, it means that each team's ratio of boys : girls must be equal to the total ratio of Boys : Girls = 36 :27= 4 / 3.

100cm

Step-by-step explanation:

since the circumference is 20cm and formula for finding a circumference of a circle is c=2(pi)r, where r is radius and pi is constant value which is equivalent to 22/7. so the radius of 20cm circumference is 3.1847 by using this eqn c/2(pi)=r. now the calculated radius will b multiply by 5 to get 15.92cm which is put in cirumference formula i.e. c=2(pi)r we get 100cm circumference.

Answer w/ explanation:

The answer is 9.1

To round to 2 significant figures, we have to find the first significant figure. We find the first sig fig by looking for the first nonzero digit in the number (it can be before or after the decimal point), which is "9"

The next digit is "0". This will also be a significant figure in our answer.

It may seem we are done now since we found the two significant figures. However, let's look at the digit after "0" to see if we need to round up or down.

The digit after "0" is "7". Since 7 is greater than 5, we round up the "0" to a "1" in our final answer, making the answer 9.1

Side note:

The definition and concept of significant figures can be very confusing overall, so please continue to ask questions if you are still struggling with them.

Answer:

First question -> y = 2

Second question -> y = 10

Step-by-step explanation:

Step 1:  Solve y + 2 = 4

Subtract 2 from both sides

y = 2

Step 2:  Solve y - 2 = 8

Add 2 to both sides

y - 2 + 2 = 8 + 2

y = 10

Answer:

The last angle is 60 degrees

Step-by-step explanation:

All triangles add up to 180 degrees

Step 1:  Make an equation

What is the angle of a triangle if one angle is 68 and the other is 52.

68 + 52 + x = 180

Step 2:  Combine like terms

68 + 52 + x = 180

120 + x = 180

Step 3:  Subtract 120 from both sides

120 + x - 120 = 180 - 120

x = 60

Answer:  The last angle is 60 degrees

The sum of the angles in a triangle will be equal to 180°.

68 + 52 = 120°

180 - 120 = 60° (This is the 3rd angle)

Answer:  6,919,320

Answer:

6,919,320.00

Step-by-step explanation:

We can conclude -

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

y = mx also represents direct proportionality. We can write [m] as -

m = y/x

OR

y₁/x₁ = y₂/x₂

Given is a straight line.

The equation of a straight line is written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

Now, from this we get -

m = -A/B     {Slope}

c = - C/A     {y - intercept}

So, the equation will be -

y = mx + c

We can also calculate slope by -

m = (y₂ - y₁)/(x₂ - x₁)

Therefore, we can write -

m = -A/B   → unit rate of change of [y] with respect to [x].

c = - C/A   → the point where the graph cuts the [y] axis.

Equation  → y = mx + c
