Answer:

Y= X - 31.5

Step-by-step explanation:

find the gradient then the equation

Answer:

y-3 = -2/15 (x-9)

Step-by-step explanation:

First, we should find the gradient, m, which is [tex]\frac{rise (change.in.the.y.value)}{run (change.in.the.x.value)}[/tex]

This is [tex]\frac{3-5}{9-(-6)} =-\frac{2}{15}[/tex]

A linear (straight) line has a general equation y=mx+c

y = [tex]-\frac{2}{15\\}[/tex]x+c

We can rewrite the equation into the general form:

y-y1 = m(x-x1)

where y1 is the value of a y coordinate and x1 is the x value of the coordinate that the y1 value was taken from.

This stems from the idea that 0 = 0.

To make that equation true, we can make both sides equal to 0.

To do that, y - y1 has to be - and x-x1 has to be zero. m can be ignored as anything multiplied by 0 is 0.

Up until here, y1 and x1 are arbitrary constants. They are values that we have to find. However, we don't actually. We have coordinates that the x and y will equal to. (9,3)

Because 9 - 9 = 0 and 3 - 3 = 0, we can state that the value of y1 is 3 and x1 is 9.

Hence, the equation is y-3 = -2/15 (x-9)

You can rearrange the equation to make it into the form y = mx + c, but this is usually not necessary.

I hope this helped.

Answer:

D) (-2, -9)

Step-by-step explanation:

X( -11, 8)

M(-6.5, -0.5)

-11 - (-6.5) = -11 + 6.5 = -4.5

8 - (-0.5) = 8 + 0.5 = 8.5

To get from Midpoint to endpoint:

(x , y) → (x - 4.5, y + 8.5)

Y endpoint:

M(-6.5, -0.5) → (-6.5 + 4.5, -0.5 - 8.5)

Y( -2, -9)

Answer:

r = 7.3 m

Step-by-step explanation:

A = (pi)(radius)^2, so, if A = 167 m^2, r^2 is found as follows:

         167 m^2

r^2 = -------------- = 53.158 m^2

              3.14

Taking the square root of both sides, we get

r = 7.3 m

This is correct, because A = (pi)(radius)^2 becomes (3.14)(7.3 m)^2 = 167.4 m^2

Answer:

(6)=120°

(10)=72°

(20)=36°

Step-by-step explanation:

(n-2)×180°

(6-2)×180°=720°

6÷720°=120°

10÷720°=72°

20÷720°=36°

Answer:

30 pieces.

Step-by-step explanation:

According to the word problem, Alex wants to cut all six of his candy bars into fifths.

5/5 = one whole candy bar.

If there will 5 pieces for every candy bar, we can multiply 5 by 6.

5 x 6 = 30.

There will be 30 of the 1/5 size pieces.

24 im pretty sure.

Step-by-step explanation:

Answer:

exterior angle: 22.5°, interior angle: 157.5°

Step-by-step explanation:

the formula for the measure of each Interior Angle in a regular polygon: [tex]\frac{180(n-2)}{n}[/tex], n = # of sides

=> [tex]\frac{180(16 - 2)}{16}[/tex] = 157.5°

the formula for the measure of each Exterior Angle in a regular polygon: [tex]\frac{360}{n}[/tex]

=> [tex]\frac{360}{16}[/tex] = 22.5°

Answer:

17.4cm

Step-by-step explanation

17) In a triangle ABC, BC=8cm, AC=12cm and angle ABC=120

To get the length of AB, we will use the cosine rule

AB² = BC² + AC² - 2(BC)(AC) cos <ABC

AB² = 8² + 12² - 2(8)(12) cos 120

AB² = 64 + 144 - 192cos12

AB² = 208 - (-96)

AB² = 208 +96

AB² = 208 - (-96)

AB² = 304

AB² = 17.4cm

Hence the length of AB is 17.4cm

Answer:

Step-by-step explanation:

This is the sum of the first 4 terms, substitute n for each term:

4

∑   [tex]\frac{7}{n}[/tex] = 7/1 + 7/2 + 7/3 + 7/4

n=1

Correct choice is A

[tex] \displaystyle \sum^{4} _{n = 1} \: \frac{7}{n} = \: 7 + \frac{7}{2} + \frac{7}{3} + \frac{7}{4} [/tex]

Answer:

Use distance formula to find the length of the segments

1. H = (-3, 0), F = (3, 2)

2. E = (1, 4), G = (-1, -2)

3. We see the diagonals are congruent, opposite sides are parallel.

The above is the property of a rectangle

Even numbers are 2,4,6,8,10 :) ✨

Answer:

Any number that can be exactly divided by 2 is called as an even number. Even numbers always end up with the last digit as 0, 2, 4, 6 or 8. Some examples of even numbers are 2, 4, 6, 8, 10, 12, 14, 16.

Answer:

A= (-1.5, 1)
