Answer:

y=9

Step-by-step explanation:

4-2y+8=-6

-2y=-4-8-6

-2y=-18 divide by -2 both side

y=-18/-2

y=9

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:

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:

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:

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.

just took the test

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

Answer:

The midpoint is (-2,14) and the slope is m=1/3

Step-by-step explanation:

blue: 4x+2+7x+7+5x -4 = 16x +5

red: x+3+x+7+2x-5 = 4x -5

difference: 16x+5 - (4x -5) = 12x +10

Answer:

1: 9

2: i dont know sorry

3: 21/2

Step-by-step explanation:

1: know that the bottom portion of the triangle is 18  the bottom left is 12 and the top left is 6. Now you could say that its six because they look the same size but we cant be sure, and six isnt an option. i dont know how to solve so we're using process of elimination so bare with me. we alread have 12 and 18 and theyre way bigger, it cant be 11 because it wouldnt be that small. so in my mind its 9.  

2:  n/A

Answer:

24 im pretty sure.

Step-by-step explanation:

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)

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:

255

Step-by-step explanation:

Once split up you find the are of the rectangle which is 8*17=136

Then since the bottom line is 22, you do 22-8 to find the bottom line of the triangle.

The area of the triangle is 17*14/2=238/2

Hence, 119

Step-by-step explanation:

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
