Step-by-step explanation:
what is the inverse of the function shown?
Answer:
The inverse is y = x + 5
Step-by-step explanation:
The general equation of a straight line is;
y = mx + c
In this case , the y-intercept is -5
So the partial equation is;
y = mx - 5
To get m, we use the x-intercept
The x-intercept coordinate is (5,0)
Insert this in the equation , we have;
0 = 5m-5
5m = 5
m = 5/5
m= 1
The equation of the line is thus;
y = x-5
So we want to find the inverse of this;
Replace x with d
y = d-5
Make d the subject of the formula
d = y + 5
replace d with x
x = y + 5
now replace x with y
So we have
y = x + 5

Answer:
B x = sqrt(41)
Step-by-step explanation:
Since the large triangle is isosceles, the smaller triangles on the right side and left side are congruent right triangles.
The base of each smaller right triangle is 4 units long (8/2 = 4).
The vertical leg is 5.
Use the Pythagorean theorem to find x.
a^2 + b^2 = c^2
4^2 + 5^2 = x^2
16 + 25 = x^2
x^2 = 41
x = sqrt(41)
Answer: B x = sqrt(41)
Answer
B
Explanation
To find the value of x, you need to use the Pythagorean theorem.
[tex]x^{2} + y^{2} = z^{2}[/tex]
x is one of the legs.
y is another one of the legs.
z is the hypotenuse (the longest side of a right triangle).
Now for this we can set 5 to be x and 4 to be y.
y is 4 because 4 is half of 8. We need to find half of 8 because the right triangle is half of the whole triangle.
Now 'plug' these into the formula and find z.
[tex]5^{2} + 4^{2} = 41^{2}[/tex]
To find z then we must find the square root of 41.
So the answer is B.
(Now I just realized that I used the variable z for the hypotenuse when you were supposed to be finding x for the hypotenuse but whatever).

A school-bus is dropping students off after school. When the bus left the
school, there were 40 students on the bus, and now there are 16. What is the
percent decrease from the start of the ride to now?
Answer:
60%
Step-by-step explanation:
40-16=24
24/40=0.6
0.6*100=60
First, work out the difference (decrease) between the two numbers you are comparing.
Decrease = Original Number - New Number
Next, divide the decrease by the original number and multiply the answer by 100.
% Decrease = Decrease ÷ Original Number × 100
Answer: 60% decrease
40 - 16 = 24
24/40 = 0.6 = 60%

Step-by-step explanation:
Which is the graph of the function y = 3x + 4?
Answer:
The top left one (It has 16 as it's highest y-point).
Step-by-step explanation:
y = 3x + 4 means the slope is 3 and the y-intercept is 4. So the y-axis goes up by 2 each time, concluding that it does intercept on y = 4 while the others don't. It also goes up 3/1, so 3 squares up and 1 to the side proving it's 3x slope.

An artist has a total of 80 paintbrushes, 22 of them are flat brushes, used
for blending. What percent of the artists' paintbrushes areflat brushes?
Answer:
27.5%
Step-by-step explanation:
To find what percent a part is of the whole, divide the part by the whole and multiply by 100%.
percent = part/whole * 100%
percent = 22/80 * 100%
percent = 0.275 * 100%
percent = 27.5%
Answer: 27.5%
Since we know the total which is 80 (which would be 100% in percents), and we want to find the percentage of 22 flat brushes.
We want to find 22 out of 80 written as a percent value?You have to convert fraction (ratio) 22 / 80
Answer: 27.5%

Answer:
x is equal to 12, y is equal to 12√2, or approximately 16.97
Step-by-step explanation:
This can be done in multiple ways, but the easiest is to realise that we are given two angle, which allows us to calculate the third.
Because the bottom left corner is 90 degrees, and the bottom right is 45 degrees, that means that the top angle is also 45 degrees. We can say this because we know that the sum of the angles inside a triangle must add up to 180 degrees.
Because those two angles are the same, we know that this is not only a right triangle, but also an isosceles triangle, with two lengths of the same size. In this case then the bottom side, x is equal to the left side: 12m.
From that we can work out y, the hypotenuse of the triangle, using the Pythagorean theorem:
[tex]y = \sqrt{12^2 + 12 ^2} \\y = \sqrt{144 + 144}\\y = \sqrt{288}\\y= 12\sqrt{2}\\[/tex]
So y, the length of the hypotenuse is equal to 12√2, or approximately 16.97

Answer:339.29
Step-by-step explanation:
The closest surface area of the container in square inches is 339.29 square inches.
The correct option is B.
What is a cylinder?A cylinder is a 3D solid form made up of two bases that are parallel and identical and are connected by a curving surface. These bases resemble spherical disks. The axis of the cylinder form is a line drawn through the center or connecting the centers of two circular bases.
Given:

Valerie, a member of the track team, runs 100 yards in 12 seconds. How fast is she moving in feet per minute?
Answer:
1500ft
Step-by-step explanation:
Ight so 60/12 is 5. So then you'd multiply 100 by 5 to get 500, therefore she is moving 500 yards per minute.
Then you'd obviously just convert that to feet which is 1500 feet.
Jasmine cut her pizza into 12 slices. Kelly cut her pizza into 6 slices, and ate 2 slices. Together, Jasmine and Kelly ate 712 of one pizza. How much of the pizza did Jasmine eat?
Answer:
Jasmine ate [tex]\frac{3}{12}[/tex] of the pizza.
Step-by-step explanation:
So the problem tells us that Jasmine cut her pizza in 12 slices while Kelly cut it only in 6 slices (see first part of the attached image)
out of the 6 slices, Kelly ate 2 slices. This represents 2/6 of the pizza. So we shade two of the 6 slices of Kelly's pizza. (See second part of the attached image).
Now for us to be able to compare the two pizzas we need to find a way for all the slices to be the same (find the Least Common Denominator). We know that 6 fits into 12 two times, so we can split each of Kelly's slices in half, so now we will have 12 slices. This means that the amount of piza Kelly ate represents:
[tex]\frac{2}{6}*\frac{2}{2}=\frac{4}{12}[/tex] of a pizza.
The problem tells us that Jasmine and Kelly together ate [tex]\frac{7}{12}[/tex] of a pizza. We know Kelly ate the equivalent to 4 slices the same size of those of Jasmine. So This means that Jasmine must have eaten 7-4=3 slices. So together they ate the equivalent to:
[tex]\frac{3}{12}+\frac{4}{12}=\frac{7}{12}[/tex] of a pizza.
therefore Jasmine ate [tex]\frac{3}{12}[/tex] of a pizza.
