Answer: for.-7x+4
Step-by-step explanation:
Formula for slope: m=y2-y1/x2-x1
Plug it in: (-10-11)/(2--1) = -21/3 = -7
M= -7
Y=mx+b
Y=-7x+b
11=-7(-1)+b
11=7+b
-7 -7
Y=-7x+4
I hope you can understand the explanation.....
1/2 (2y-6) = 24
1/4 (4-y) = 10 + 24
2 (2y-3) = 4y-6
1/3 (6y-9) = 24 - 3
I think they’re linear equations but I don’t know what to do. The directions say to solve if possible??

If you purchase a DVD player that costs $625, and the tax rate is 8%, how much will it cost?
Answer:
675
Step-by-step explanation:
8%=$50
Answer:
$675
Step-by-step explanation:
Since tax is an added 8% you are in sense paying for 100% of the DVD and 8% for tax, or 108% of the DVD player. Now convert percent to decimals by dividing by 100 to get 1.08. Now you can multiply 1.08 x $625 and get $675

Answer:
A 7/25
Step-by-step explanation:
The cosine of an angle is equal to the sine of its complement. In a right triangle, angle A is the complement of angle B. So, ...
cos(A) = sin(B)
cos(A) = 7/25

determine the intercepts of the line
Answer:
X-Intercept: (-8,0)
Y-Intercept (0, -6)
Step-by-step explanation:
The x intercept is where the line intercepts with the line where y is 0, which is the dark horizontal line on the graph. The y intercept is founf the same way instead on the dark vertical line where x is 0.

what is the system of inequalities for the graph below?
Answer:
hi do You have Instagram?
9514 1404 393
Answer:
y ≥ -2x +1y ≤ 2x +4Step-by-step explanation:
The downward-sloping line has a y-intercept of 1 and a slope of -2, so its equation is ...
y = -2x +1
The graph is shaded on and above that line, so the inequality it represents is ...
y ≥ -2x +1
__
The upward-sloping line has a y-intercept of +4 and a slope of +2, so its equation is ...
y = 2x +4
The graph is shaded on and below that line, so the inequality it represents is ...
y ≤ 2x +4
Then the system of inequalities is ...
y ≥ -2x +1
y ≤ 2x +4

Payton spent half of her weekly allowance on clothes. To earn more money, her parents let her clean the oven for $8. What is Payton weekly allowance if she ended with $15
Answer:
Payton's weekly allowance is $14.
Step-by-step explanation:
If she ended up with $15 after earning $8, then we to subtract 15 by 8.
15 - 8 = 7
If Payton spent half of her allowance before earning more money from her chore, then her allowance must be 7 times 2.
7 x 2 = 14.
Therefore, Payton's weekly allowance is $14.
Hope this helps! :)

Determine two numbers that have a product of 40 but have a sum of 13.
Answer:
The two numbers are 8 and 5.
Step-by-step explanation:
Let consider x and y to be these two numbers.
So;
(x) * (y) = 40 ---- (1)
x + y = 13 ----- (2)
From (2), let x = 13 - y
Then;
(13 - y) * y = 40
13y - y² = 40
13y - y² - 40 = 0
-y² + 13y - 40 = 0
Multiply through by (-)
y² - 13y + 40 = 0
By factorization;
(y - 8) (y - 5) = 0
y = 8 or y = 5
CHECK:
8 * 5 = 40
8 + 5 = 13
Therefore, the two numbers are 8 and 5.

find the area of the regular polygon
Answer:
433.4
Step-by-step explanation:
Height will be (14/2)/tan36 which is 9.63, then area for one triangle is 1/2*hb which is .5*9.63*7 is 43.34, times 10 you get 433.4
-3 (3c + 5) = 2 (10 - c)
Answer:-5
Step-by-step explanation:
You need to distribute on both sides so u get
9c-15=20-2c
Move variable to left side and change the sign
-9c+2c-15=20
Move constant to right side and change the sign
-9c+2c=20+15
Connect like terms
-7c=35

Answer:
This relation is a function.
Step-by-step explanation:
This relation is a function because a there should be no repeating x-coordinates in the relation for it to be a function and that is exactly what happens in this relation.
Answer:
It is a function.
Step-by-step explanation:
no two different outputs, y, have the same input, x, meaning it passes the vertical line test.

A ladder is placed against a wall such that the top is 8 feet above the ground. If the ladder is 10 feet long, how far away from the wall is the base of the ladder
Answer:
6 feet
Step-by-step explanation:
Consider the right triangle formed by the wall, ladder and ground.
Let the distance the ladder is from the wall be d , then
Using Pythagoras' identity in the right triangle
The square on the hypotenuse ( ladder) is equal to the sum of the squares on the other 2 sides ( wall and d ), then
d² + 8² = 10²
d² + 64 = 100 ( subtract 64 from both sides )
d² = 36 ( take the square root of both sides )
d = [tex]\sqrt{36}[/tex] = 6
That is the ladder is 6 feet away from the wall

A packet of green plantains has 5 plantains. Felix packs 3/5 of a package every 25
seconds. After packing plantains for 1 2/3 hours, how many packages has he prepared?
Answer:
166 Packages
Step-by-step explanation:
1 2/3 hours equals 1 hour and 40 minutes.
100/ (3/5)
166 2/3, we remove the 2/3 since its asking for a whole number
can someone teach me how to write this in standard form ?
Answer:
2x + 5y = 7
Step-by-step explanation:
Here, 2x = 7 - 5y is given
The Standard form of equation is
Ax + By = C
Here, Ax = 2x; By = -5y; C = 7
Now, we get
2x = 7 - 5y
2x + 5y = 7
Here we get Ax = 2x; By = 5y; C = 7
Thus, The Standard form of equation is
2x + 5y = 7

At 8:00 am, the temperature was -10°F. The temperature dropped 3 degrees per hour for the next 5 hours. What was the temperature at 1:00 pm?
Answer:
-25 °F
Step-by-step explanation:
First, we would be multiply 3 by 5 to find the number we would be subtracting from the original
3 * 5 would give us 15
Then we subtract -10 by 15 and get -25 °F
The temperature at 1:00 PM would be -25 °F
Solve 4(x-1) = 2(6-2x)
Answer:
x=2
Step-by-step explanation:
4(x-1) = 2(6-2x)
x=2
Answer:
x=2
Step-by-step explanation:
4(x-1)=2(6-2x)
4x-4=12-4x
Add 4 to both sides
4x=16-4x
Add 4x to both sides
8x=16
Divide by 8 on both sides
x=2
