Answer:
y = 2/5x - 5
Step-by-step explanation:
(-10,-9) and (10,-1)
Slope: (-1 - - 9) / ( 10 - - 10)
Slope = 8/20 = 2/5
b = -9 - (2/5(10)
b = -5
The equation of the line that passes through the point (−10,−9) and (10,-1) is; y = 2/5x - 5
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Where x₁ - x coordinate, y₁ - y coordinate, m - slope
Slope: (-1 - - 9) / ( 10 - - 10)
m = Slope = 8/20 = 2/5
Now intercept;
b = -9 - (2/5(10)
b = -5
Now Write the equation as
y = 2/5x - 5
Hence, the equation of the line that passes through the point (−10,−9) and (10,-1) is; y = 2/5x - 5

3. Kenny can type 75 words in 3 minutes. What is the constant of
proportionality that relates the number of words, y, to the number of
minutes, x?
Answer:
25Step-by-step explanation:
Let this relationship be:
y = kx, where y is the number of words in x minutes.Use the given numbers to find the value of k:
75 = 3kk = 75/3k = 25Find the expression that is equivalent to:
x2 - 16x + 64
a (x – 8)(x + 8)
b (x + 8)(x + 8)
c (x + 8)^2
d (x – 8)^2
Answer:
D. (x – 8)^2
Step-by-Step Explanation:
x2 - 16x + 64:
Step 1: Use the sum-product pattern.
[tex]x^{2} -16x+64\\x^{2} -8x-8x+64[/tex]
Step 2: Common factor from the two pairs.
[tex]x^{2} -8x-8x+64\\x(x-8)-8(x-8)[/tex]
Step 3: Rewrite in factored form.
[tex]x(x-8)-8(x-8)\\(x-8)(x-8)[/tex]
Step 4: Combine to a square.
[tex](x-8)(x-8)\\(x-8)^{2}[/tex]

The two figures are similar. Find the ratios (red to blue) of the perimeters and of the areas. Write the ratios as fractions in simplest form. 6 and 11
Answer:
see explanation
Step-by-step explanation:
The perimeters of the similar figures have the same ratio as the sides.
ratio of perimeters = [tex]\frac{11}{6}[/tex]
ratio of areas = 11² : 6² , that is 121 : 36
ratio of areas = [tex]\frac{121}{36}[/tex]

Write 1/4 on the number line.
Answer:
Step-by-step explanation:
Answer:
We have to represent 1/4 in the number line .
So simply will first write it in Fraction form that is
So we have to represent it on number line .
1/4 we have to mark on the right side of number line because it is a positive number having no negative number . That is why we will mark it on the right side of the number line .
As we know the denominator is 4 so between every number we will keep four points distance.
After the zero the first point is number 1 and number 2 and number 3 and so on ...
The four points will consider number 1 , 2 , 3 , 4 and so on ...number after four points I have written 1 because there is the denominator 4 so we should keep 4 points distance in each number .
So , The number 1 we will mark and write the denominator 4

Three interior angles of a polygon are 125,140 and 160. The remain angles are 145 each. Calculate the sum of the interior angles of the polygon
Answer:
1440 degrees.
Step-by-step explanation:
125 + 140 + 160 = 425 degrees.
The remaining angles are each 145.
The exterior angles of all polygons sum to 360 .
So we have exterior angles sum of the 3 given angles
= (180-125) + ( 180-140) + (180-160)
= 55 + 40 + 20 = 115.
So the remaining vale of the sum is 360 - 115
= 245 degrees.
An internal angle of 145 will give an external one of 35 degrees.
245/35 = 7.
So there are 7 145 degree angles in the polygon.
Sum of the interior angles is therefore:
425 + 7*145
= 1440 degrees.
This is a 10 sides polygon ( a decagon).

Step-by-step explanation:
it takes a snail 10 seconds to move 1 centimeter. How far does snail travel in 2 seconds
Answer:
0.2
Step-by-step explanation:
If it takes 10 seconds to move 1 centimetres, and you want to know about 2 seconds, you can divide by 5 on both sides.
1/5 = 0.20
It takes 2 seconds to move 0.2 centimetres (aka 20 milimetres).
The snail will travel 0.2 centimetre in 2 seconds.
it takes the snail 10 seconds to move 1 centimetre. The means in every 10 seconds the snail moves 1 centimetre.
The distance the snail can cover in 2 seconds can be computed below:
10 seconds = 1 cm
2 seconds = ? cm
cross multiply
distance it takes the snail to travel in 2 seconds = 2 / 10
distance it takes the snail to travel in 2 seconds = 1 / 5
distance it takes the snail to travel in 2 seconds = 0.2 cm
Therefore, the snail will travel 0.2 cm in 2 seconds .

use the slope-intercept form to graph the equation y=7x-4.
20 pts !!!
first, let's break the equation down.
y=7x-4
-4 represents your staring coordinate, or your y-intercept. This is because -4 does not have an x after so you know it is equal to your y value. So you start at (0,-4)
Now all you need to do is the y=7x part.
The 7x represents your slope.
Slope is equal to rise/run or y/x.
So for each coordinate, you go up 7 and to the right 1.
(0,-4)
(1,3)
(2,10)

How do you solve the system of equations with Cramer's rule?
Drag a value or determinant expression into each box to correctly solve the system using Cramer's rule.
The solution to the system of equations x + 2y = 1 and -3x-2y = 5 is:
