the answer for this is y=mx+b

Answer:

The table gives you three points that are on the line:

(-5, -7), (0, -5), (3, -3)

use any two of them to find the slope.

For the given similar polygons, the value of x equal to 30.

Two polygons are classified as similar when their angles are congruent and their sides are proportional.

If the polygons of this exercise are similar. You can write:

                                   [tex]\frac{LK}{QR}=\frac{JK}{PR}=\frac{JL}{PQ}[/tex]

Then,

                                    [tex]\frac{LK}{QR}=\frac{JK}{PR}=\frac{JL}{PQ}\\ \\ \frac{18}{12}=\frac{x}{20}=\frac{21}{14}[/tex]

It is possible to note that the scale factor is  [tex]\frac{3}{2}[/tex].  See it.

                                         [tex]\frac{18:6}{12:6}=\frac{3}{2} \\ \\ \frac{21:7}{14:7}=\frac{3}{2}[/tex]

Therefore, you can find x from:

                                      [tex]\frac{18}{12}=\frac{x}{20}\\ \\ 12x=18*20\\ \\ 12x=360\\ \\ x=\frac{360}{12} =30[/tex]

Answer:

6.8

Step-by-step explanation:

This is the answer because:

1) The square root of 46 is 6.78232998...

2) The nearest tenth of this is 6.8 because we have to round 7. Since 8 is greater than 5, we have to round 7 up.

Therefore, the answer is 6.8

Step-by-step explanation:

I hope this helps!

Answer:

-10

Step-by-step explanation:

To find the answer to -2 - 8, we have to remember that when you subtract numbers, they go towards the negatives. So, since it is -2 - 8, you basically just add together the numbers but keep the negative sign, so the answer would be:

-2 - 8 = -10

y = 3x + 2 = 3 * x + 2

point (10 ; 32) on the line ?

so here we can read : x = 10 and y = 32

if x = 10

then y has to be = 3 * 10 + 2 = 30 + 2 = 32

so yes - on the line

same reasoning for the rest

The ordered pairs which does not lie on the graph of the function are (8,13).

Function is relationship between two or more variables expressed in equal to form. In a function each value of x must have corresponding value of y.

The value which we put in the function is domain of the function and the value which we will get is known as codomain of the function.

We have been given a function y=3x+2 and we have to find the ordered pairs which does not lie on graph of function. The ordered pairs which lie on the graph must satisfy the function and the ordered pairs which does not lie on the graph must not satisfy the function.

First ordered pair is (10,32)

32=3*10+2

32=30+2

32=32

It lies on graph.

Second ordered pair is (8,13)

12=3*8+2

12=24+2

12≠26

So it does not lie on graph of function y=3x+2.

Hence the ordered pair which does not lie on the graph of function y=3x+2 is (8,13).

Substitute the values into the expression to find the perimeter.

Answer: 28cm

Step-by-step explanation:

The perimeter formula for a rectangle = 2(l + w); where:

length = 9cm

width = 5cm

P = 2(l + w)

= 2(9 + 5)

= 18 + 10

= 28cm

Therefore, the perimeter of the cheese is 28cm

Answer:

Step-by-step explanation:

Given the x-intercepts at -1 and 5, that means y=0 at x=-1 and x=5.

So (x+1) and (x-5) are root for the parabola.

y = (x+1)*(x-5)

That is the quadratic equation for Question B.

Back to A, the x-coordinate of vertex of this parabola is at x=2.

This is because the parabola is symmetrical at its vertex so the vertex must be at the mid-point between its x-intercepts, x=(-1+5)/2=2.
