Answer:

y=−x+2y=4x+7   NO

y=−x+2               YES

y=4x+7            

Multiply the first equation by 4, obtaining:              4y = -4x + 8

Add the 2nd equation to this result:                          y = 4x  + 7

                                                                            --------------------

                                                                                5y = 15, and y = 3

Then, using the first equation, determine x:

y = 3 = -x + 2

      1 = -x, so x = -1

The solution is (-1, 3)

Answer: (-1; 3)

Step-by-step explanation:

y = -x + 2

y = 4x + 7

4x + 7 = -x + 2

4x + 7 + x - 7 = - x + 2 + x - 7

5x = - 5

x = - 1

y = 4(-1) + 7

y = 3

Intersection point: (-1; 3)

Answer:

The length of segment TR with T(-4,5) and R(2, -1)​ is 8.49

Step-by-step explanation:

We need to find the length of segment TR with T(-4,5) and R(2, -1)​

The length of segment can be found using distance formula.

The distance formula is: [tex]Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Putting values and finding length

We have: [tex]x_1=-4, y_1=5, x_2=2, y_2=-1[/tex]

[tex]Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance = \sqrt{(2-(-4))^2+(-1-5)^2}\\Distance = \sqrt{(2+4)^2+(-1-5)^2}\\Distance = \sqrt{(6)^2+(-6)^2}\\Distance = \sqrt{36+36}\\Distance = \sqrt{72}\\Distance=8.49[/tex]

We found Distance = 8.49

So, The length of segment TR with T(-4,5) and R(2, -1)​ is 8.49.

The  total length of a beam bridge is 168 yards. then the span between any two consecutive supports is 23 approx.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Given that the total length of a beam bridge is 168 yards.

The Total number of supports on the bridge = 1 at both end + 3 additional = (1 + 3 + 1) = 5 supports

Arch lies in between two successive supports ;

Hence, the number of archs = 5

Hence, width of arch = (5 * x) = 5x meters

Width of support = 2 meters

The Total width of support : (2 * x+ 1) = 2(x + 1) meters

Hence,  the total distance of bridge :

Total arch width + total support width

5x  + 2(x + 1) = 168 meters

5x + 2x + 2 = 168

7x = 166

x = 23 approx

Hence, the span between any two consecutive supports is 23 approx.

Answer:

60 stores

Step-by-step explanation:

Here, we want to get the total number of stores in which Esther and her 6 brothers went shopping

From the question, she shopped in 12 different stores

Each of her six brothers shopped in 8 different stores

That makes the number of stores in which the brothers shop be 8 * 6 = 48 stores

The total number of stores is thus, 48 + 12 = 60 stores

Answer:

24+15k=

Step-by-step explanation:

First we multiply the 6 to the numbers in the parentheses, so 4x6=24, and 2x6=12, making the expression look like this: 24+12k+3k=

Then we combine like terms, which would be the number that are attached to 'k'. So that makes the expression look like this: 24+15k=

I'm not sure what else you're suppose to do to create a new expression since there's nothing on the other side of the equal sign, but that's as much as the expression will simplify.

Answer:

The slope of a line that is perpendicular to the x-axis ​is undefined.

Step-by-step explanation:

We know that the x-axis is a horizontal line.

Therefore, the slope of a line that is perpendicular to the x-axis ​is undefined.

For example, the slope between (1, 2) and (1, 4) is:

Using the slope formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                 = [4 - 2] / [1 - 1]

                  = 2 / 0

                  = ∞

Simply plug in the 2 coordinates into the slope formula to find slope m. Slope and gradient is the same.

Answer:

Let "m" be the slope of the line passing through the point.

[tex]m = \frac{y_ 2 - y_1}{x_ 2 - x_1 } = \frac{( - 10 - 0)}{(5 - 0)} = \frac{ - 10}{5} = \boxed{- 2 }[/tex]
