Answer:

3

Step-by-step explanation:

We can use the formula of slope to find this answer.

The formula to find the slope is y2-y1/x2-x1.

The slope of line ST is 1/5: 2-0/5-(-5);   2/10=1/5

We know that for two lines to be perpendicular, they have to have reciprocal opposite slopes. For example, if the slope of a line is 2/1 then the slope of a line perpendicular is -1/2.

Therefore, the perpendicular line should have a slope of: 1/5------>-5

To find which answer it is, follow the steps below:

y2-y1/x2-x1

plugin known values

-2-y1/0-(-1)

-2-y1/1

In order to make this -5, y1 needs to be 3

-2-3/1=-5

3 is the correct value

The value of y is 3.

The slope of a line is a measure of its steepness.

Given:

Ware( -1, y)

Now,

slope of line ST =2-0/5-(-5)

slope=1/5

As two lines to be perpendicular, they have to have reciprocal opposite slopes.

Thus, the perpendicular line slope =-5

Now, y2-y1/x2-x1

= -2-y1/0-(-1)

= -2-y1/1

= -2-3/1

=-5

hence, the value of y is 3.

Step-by-step explanation:

do an opposite angle to get the top of the left triangle so it will be 28

Given:

The equation is

[tex]4(2x-3)-(mx+5)=5x+b[/tex]

To find:

The values of m and b.

Solution:

We have,

[tex]4(2x-3)-(mx+5)=5x+b[/tex]

Using distributive property, we get

[tex]8x-12-mx-5=5x+b[/tex]

On combining like terms, we get

[tex](8-m)x+(-12-5)=5x+b[/tex]

[tex](8-m)x-17=5x+b[/tex]

On comparing both sides, we get

[tex](8-m)=5[/tex]

[tex]-m=5-8[/tex]

[tex]-m=-3[/tex]

[tex]m=3[/tex]

And,

[tex]b=-17[/tex]

Therefore, m = 3 and b = 17.

The sum the model below represents will be 4 + (negative 7) = negative 3. Option A is correct.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, the expression is 4 positive tiles and 7 negative tiles. We have to apply summation for the given expression,

Expression is the combination of constants and variables with mathematical operators.

The model is algebraically solved as,

=4+(-7)

= -3

Thus, the sum the model below represents will be 4 + (negative 7) = negative 3. Option A is correct.

Answer:

x + 7 = 14  //  x - 5 = 2  //  x - 9 = -2  //  3x - 15 = 6 … (x = 7)

2x - 1 = 7  //  2x - 5 = 3 … (x = 4)

2x - 3 = 3  //  2x + 5 = 11  //  4x + 2 = 14  //  2x + 1 = 7 … (x = 3)

12x - 3 = 24  //  4x - 1 = 8 … (x = 9/4)

Answer:

72

Step-by-step explanation:

-2 x -4 = 8

8 x 9 = 72

Hope this helps! Please mark Brainliest!

Answer:

72 = Positive

Step-by-step explanation:

The property we use,

→ Associative property

Now the product will be,

→ (-2 × -4) × 9

→ 8 × 9 = 72

→ -2 × (-4 × 9)

→ -2 × (-36) = 72

Then the required sign is,

→ Positive (+ve)

Hence, the product is 72.

The answer to this problem is 35 :)

Answer:

35

Step-by-step explanation:

(-2,-1) to (3,-1) is 5 units which is the length, and (-2,6) to (-2,-1) is 7 units which is the height, so using the formula for perimeter: length x height, 5 x 7 = 35

Answer:

2 inches of snow was left on the ground

Step-by-step explanation:

To calculate the amount of snow on the ground we can take it one step at a time. Since there was no snow on the ground we can start at a level of 0. Then it snowed until 6 inches of snow had fallen, so we can add that to our total.

0 + 6 = 6 inches

Next, it snowed for 2 more hours at a rate of 2 inches per hour, meaning we multiply this by 2 hours and add to the total amount of snow that was already on the ground.

(2*2) + 6 = 10 inches

Lastly, the sun came out and melted the snow on the ground for 2 hours at a rate of 4 inches per hour. Since it is melting the snow, this means that it is subtracting the snow from the total. So we would have to multiply the rate (4 inches per hour) by the number of hours and then subtract that from the amount of snow on the ground.

10 - (4*2) = 2 inches

Answer:

  (-6, -4)

Step-by-step explanation:

If you're going to use technology to answer your questions, you may as well use appropriate technology: a graphing calculator. It shows the solution to the system is the ordered pair (-6, -4).

__

The first of the given equations can be solved for y, then that used to substitute for y in the second equation.

  y = 5x +26

  2x -7(5x +26) = 16

  2x -35x -182 = 16

  -198 = 33x . . . . . . . . add 33x-16

  -6 = x . . . . . . . . . . . . divide by 33

  y = 5(-6) +26 = -4 . . . find y

The solution is (x, y) = (-6, -4).

Answer:

length: 15 units

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Take a look at the slope-intercept form of the equation .

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

Slope of 9/7 and y-intercept of 1/3 means replace m which is slope and c is the y-intercept which becomes

[tex]y=\frac{9}{7}x+\frac{1}{3}[/tex]

now we take LCM of 7 and 3 which becomes

[tex]y=\frac{27x+7}{21}[/tex]

and then,

[tex]21y=27x+7[/tex]

so A is our Answer

if arrange the equation accordingly
