Answer:

17

Step-by-step explanation:

if a=2 then

4(2)-2x is greater than or equal to 13(2)

8-2x is greater than or equal to 26

You now have to find the smallest number that will accurately fit this equation. In this case it is 17.

8-2(17) is greater than or equal to 26

8-34 is greater than or equal to 26

26 is greater than or equal to 26

Answer:

[tex]d\approx 16.16\ units[/tex]

Step-by-step explanation:

Distance Between two Points in the Plane

Given two points A(x,y) and B(w,z), the distance between them is:

[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]

The triangle formed by the points N (7,3), 0(-8, -3), and  P(-8,-8) is shown in the image provided.

We are required to find the distance between N and O:

[tex]d=\sqrt{(-3-3)^2+(-8-7)^2}[/tex]

[tex]d=\sqrt{(-6)^2+(-15)^2}[/tex]

[tex]d=\sqrt{36+225}[/tex]

[tex]d=\sqrt{261}[/tex]

Since 261=9*29:

[tex]d=3\sqrt{29}[/tex]

[tex]\mathbf{d\approx 16.16\ units}[/tex]

Answer:

Simplifying

y = 12x + 25

Reorder the terms:

y = 25 + 12x

Solving

y = 25 + 12x

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Simplifying

y = 25 + 12x

Answer:

G is equal to (8, -11)

Step-by-step explanation:

We are given the midpoint and one end of the line segment.  We can find the other end of it by taking the distance from H to M, doubling it, and adding that to H:

[tex]G(x, y) = H(x, y) + 2(M(x, y) - H(x, y))\\\\G_x = H_x + 2(M_x - H_x)\\G_x = -4 + 2(-6 - (-4))\\G_x = -4 + 2(-2)\\G_x = -4 - 4\\G_x = 8\\\\G_y = H_y + 2(M_y - H_y)\\G_y= 3 + 2(- 3 - 4)\\G_y= 3 - 6 - 8\\G_y = -11[/tex]

So the coordinates of endpoint G are (8, -11)

Answer: n=3

Step-by-step explanation:

Understand that you need to set up a proportion before you can try to solve the question through guessing. In this case, YZ would be proportional to XY as EF is proportional to DE. You would write this as: EF/DE=YZ/XY.

Now you want to write an equation. In order to do this remember to multiply by your proportion. Here’s my equation:

5/4(4n+4)=7n-1. Now distribute:

5n+5=7n-1. Now simplify:

6=2n. Now simplify again:

n=3

Hope this helps you with your big ideas math hw!

The value of is n=3

5/4(4n+4)=7n-1.

Now distribute:

5n+5=7n-1.

Now simplify:

6=2n.

n=3

Step-by-step explanation:

Step 1:

5x - 2y = -18

x - 8y = 80

__________

Step 2:

4(5x - 2y) = (-18)4

20x - 8y = -72

Answer:

17/4 divided by 4 = 4  and 1/4

Step-by-step explanation:

In order to find the mixed number you have to divide the numerator by the denominator.

Answer: A

Explanation:

Step 1: Use the linear graph to create an equation using slope-intercept form. The y-intercept is (0,-6) because that's where the line passes the y-axis. The slope is 1/2 and that's pretty self-explanatory if you know how to find slope. The equation would be y=1/2x-6.

Step 2: Because we are looking for a line perpendicular to the linear graph, the y-intercept and slope needs to be different. If they're perpendicular, they need to intersect, so the slope needs to be the reciprocal of the original slope, 1/2. The reciprocal is -2. Your equation would be y=-2x+b, and since we don't know the y-intercept, we would leave it as b.

Step 3: Plug in the given ordered pair, (-3,-2), to get -2=-2(-3)+b. You would result with -2=6+b. Subtract 6 to both sides and you would get b=-8.
