Can somebody please help me?!! I will give BRAINLIEST!!
Answer:
Step-by-step explanation:
Mark the two points (-1,7) and (1,-1) on the graph. Then draw a straight line between them. To determine the equation that goes through these two points, we can use the two given points to find the slope of the line. The standard form of a straight line equation is
y = mx + b,
where m is the slope and y is the y-intercept (the value of y when x = 0).
Slope is also known as the "Rise"/"Run" - the change in y divided by the change in x. We can use the two points to calculate this:
Rise (-1-(7) = -8 Run = (1 - (-1) = 2
The slope is therefore (-8/2) or -4.
y = -4x + b
We can find b by entering either of the two points in y = -4x + b and solve for b. I'll use (1,-1) since I have my 1's multiplication table memorized
y = -4x + b
-1 = -4(1) + b
b = 3
The straight line equation that connects the two points is
y = -4x + 3
You can graph this equation (e.g., on DESMOS) to see how it intersects the points. [Attached]
The coordinates of the y intercept are (0,3).
The coordinate of the y-intercept of the line is (0, 3)
Equation of a line
The equation of a line in slope-intercept form is expressed as y = mx + b.
where:
m is the slope the lineb is the y-interceptGiven the coordinate points (-1, 7) and (1, -1).
Get the slope
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{-1-7}{1-(-1)}\\ m=\frac{-8}{1+1}\\ m=\frac{-8}{2}\\ m=-4[/tex]
Get the y-intercept:
Recall that y = mx + b
Using the coordinate point (1, -1) and m = -4
-1 = -4(1) + b
-1 = -4 + b
b = -1 + 4
b = 3
The equation of the line is y = -4x + 3
Get the y-intercept:The y-intercept occurs at the point where x = 0
y = -4(0) + 3
y = 0 + 3
y = 3
Hence the coordinate of the y-intercept of the line is (0, 3)

Maribel will borrow $6250 at 13.5% APR. She chooses to pay it back in 2 years.
What will her monthly payment be? Use the table.
Use the rate table to figure out the monthly payments per one hundred dollars.
At a rate of 13.5% the interest per $100 is $ 4.778 per month.
Therefore, for two years the payment will be
$4.778 × 24 = $114.672 per $ 100
Therefore, the interest for a principal $6250 for two years;
(6250/100) × 114.672
= $7167
The monthly payment would therefore be
7167/24
= $298.625
≈$298.63

Let the number of nickels is n, number of quarters is q.
We know that:
Nickel = 5¢, quarter = 25¢, $2 = 200¢As per given we can set the following system:
n + q = 125n + 25q = 200Solving this we get:
n = 5, q = 7add the following rational number =
3/11 and -5/12
Answer:
-19/132
Step-by-step explanation:
To add fractions, find the lowest common multiple of the two denominators and multiply accordingly to make both denominators the same. In this case, the lowest common multiple of 11 and 12 is 132, so we need to multiply the first number by 12 and the second by 11. So we get [tex]\frac{36}{132} + (-\frac{55}{132} )[/tex] = [tex]\frac{36-55}{132}[/tex]=[tex]\frac{-19}{32}[/tex][tex]-\frac{19}{132}[/tex]

Step-by-step explanation:
To find a percent of a number, multiply the percent by the number. First, change the percent into a decimal number by moving the decimal point of the percent 2 places to the left. For example, 42% = 0.42; 7% = 0.07
Part a.
8% of 9,970,000 km²
Step 1. Multiply the percent by the number
8% of 9,970,000 km² = 8% × 9,970,000 km²
Step 2. Change the percent into a decimal number by moving the decimal point of the percent 2 places left.
8% of 9,970,000 km² = 8% × 9,970,000 km² = 0.08 × 9,970,000 km²
Step 3. Use a calculator or long division to do the multiplication.
0.08 × 9,970,000 km² = 797,600 km²

Part b.
Subtract the area of part a. from the total area of Canada.
9,970,000 km² - 797,600 km² = 9,172,400 km²
Answer: b. area not covered in fresh water is 9,172,400 km²
Part c.
Tundra is 23% of total area.
23% of 9,970,000 km²
Step 1. Multiply the percent by the number
23% of 9,970,000 km² = 23% × 9,970,000 km²
Step 2. Change the percent into a decimal number by moving the decimal point of the percent 2 places left.
23% of 9,970,000 km² = 23% × 9,970,000 km² = 0.23 × 9,970,000 km²
Step 3. Use a calculator or long division to do the multiplication.
0.23 × 9,970,000 km² = 2,293,100 km²
Answer: a. area covered in tundra is 2,293,100 km²

Step-by-step explanation:
Given that Sophia bought 3 bags of candy, and each bag has 15 pieces:
[tex]3*15 = 45[/tex]
Sophia has 45 total pieces of candy.
If Sophia would like to fill 9 party bags with the candy she has bought, she must divide the 45 total pieces of candy into the 9 party bags:
[tex]45[/tex] ÷ [tex]9=5[/tex]
Therefore, each party bag will have 5 pieces of candy in it.
Answer:
A. 5
Step-by-step explanation:
A, since you can follow these steps:
First, find how many total pieces of candy must be distributed. This is always what needs to be answered in this sort of question.
In this case, it is 3 bags of candy ⋅ 15 pieces of candy in each.
The result - from 3(15) - is 45 total pieces of candy.
Now, we see that we're distributing that value among 9 people (this is another correct way of wording it).
So the result is 45/9, which then results in 5 pieces of candy for 9 guests.

Calculate the slope of the line for Graph C.
Answer:
[tex]- \frac{5}{4}[/tex]
Step-by-step explanation:
Use the slope form:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
m = slope
Let:
[tex](x_1 , y_1) = (-2 , -8)\\(x_2 , y_2) = (-6 , -3)[/tex]
Plug in the corresponding numbers to the corresponding variables, and solve:
[tex]m = \frac{-3 - (-8)}{-6 - (-2)} = \frac{-3 + 8}{-6 + 2} = \frac{5}{-4} = -\frac{5}{4}[/tex]
[tex]- \frac{5}{4}[/tex] is your answer.
A grid is 10 squares high and 10 squares wide. The distance between each grid square is 3 feet. The triangular viewing area of camera is shown. The right triangle has 2 sides with lengths of 5 grid squares. The area of the triangle is 112.5 feet squared.
Alan wants to install security cameras in his store, which has dimensions of 30 feet by 30 feet. Each camera can view an area of approximately 112.5 ft2, with a viewing area shaped like a right triangle.
How many cameras will be necessary to cover the entire store?
.
If he places cameras only in the corners of the store, how much area is left uncovered?
ft2.
Answer:
1) 8
2) 450 ft^2
Step-by-step explanation:
Each triangle takes half a square worth of space, so if you add up 2 triangles for 1 square that is 1/4 of the area, multiply that by 4 and you get 8 cameras.
The left over space in the store is the same amount of space as all the cameras space added together since each camera takes up half a square. That way 4 cameras(each 112.5 ft^2 each) equals 1/2 of the room which added together is 450 ft^2, the other half would be the left over space, 450 ft^2.
1) The cameras will be necessary to cover the entire store are 8
2) The area left uncovered is 450 ft^2
Each triangle takes half a square worth of space, so if you add up 2 triangles for 1 square that is 1/4 of the area, multiply that by 4 and you get 8 cameras.
What is the area of the triangle?
The area of the triangle is
[tex]=\frac{1}{2}\times height \times base[/tex]
The leftover space in the store is the same amount of space as all the camera's space added together since each camera takes up half a square.
That way 4 cameras(each 112.5 ft^2 each) equals 1/2 of the room which added together is 450 ft^2, the other half would be the leftover space, 450 ft^2.
1) The cameras will be necessary to cover the entire store are 8
2) The area left uncovered is 450 ft^2

segment DE is a midsegment of triangle ABC. find the value of x
Answer:
x = 10
Step-by-step explanation:
The value x is 10 units.
What is midsegment?A midsegment is the line segment connecting the midpoints of two sides of a triangle. Since a triangle has three sides, each triangle has three midsegments.
Given that, segment DE is a midsegment of triangle ABC.
According to the midpoint theorem, “The line segment in a triangle joining the midpoint of two sides of the triangle is said to be parallel to its third side and is also half of the length of the third side.”
Therefore, DE = 1/2 AB
5 = 1/2x
x = 5×2
x = 10
Hence, the value of x is 10 units.
