What is the range of the function y = 3x + 2 when the domain is {-3, 0, 2}?
Answer:
{-7, 2, 8}
Step-by-step explanation:
We see that the domain is limited to three x-values: -3, 0 and 2. To find the range (which is the set of all y-values) we just need to plug-in these x-values and find the corresponding y-values.
So our equation is:
y = 3x + 2
Then we substitute for the x-values:
y = 3(-3) + 2
y = -9 + 2
y = -7
y = 3(0) + 2
y = 0 + 2
y = 2
y = 3(2) + 2
y = 6 + 2
y = 8
So our range would be {-7, 2, 8}.

please help me, i have no clue what to do all it says is find the slopeof the line that passes through the given two points using ratio method.
Answer:
Δy = 9
Δx = -6
Slope = -3/2
Step-by-step explanation:
The slope formula is the change in y (Δy) over change in x (Δx).
Δy = [tex]y_2-y_1[/tex]
Δx = [tex]x_2-x_1[/tex]
We are given the points of (5,-3) and (-1,6).
[tex]m=\frac{6-(-3)}{-1-5}=\frac{9}{-6}=\boxed{-\frac{3}{2}}[/tex]
The slope is -3/2.

What is the best estimate of the perimeter of the figure below if each square has a side length of 1 foot? On a coordinate plane, a figure is 30 units around. 26 feet 28 feet 30 feet 39 feet
Answer:
28 feet
Step-by-step explanation:
Since each side length of the square is 1 foot.
Let x represent the length of the small slant side and y represent the length of the long slant side. Hence:
x² = 5² + 1²
x² = 26
x = √26 = 5.1 feet
y² = 6² + 3²
y² = 45
y = 6.7 feet
The perimeter of the figure is the sum of all the sides of the figure, hence:
Perimeter = 11 feet + 4 feet + 5.1 feet + 6.7 feet + 2 feet = 28.8 feet
Therefore the best estimate of the perimeter of the figure below is 28 feet.

can u help me find the area
Answer:
640 units squared
Step-by-step explanation:
The shape below is a trapezoid.
The formula for the area of a trapezoid is average of the bases times the height.
The bases are the parallel lines that make up 2 of the sides of the trapezoid.
The height is the line dotted line that creates right angles and is the distance between the two bases.
The bases are 24 and 40.
To find the average, we add them together and divide by 2
(24+40)/2=64/2=32
Now, we multiply 32 by the height, which is given as the length of 20.
32*20=640
the area of the trapezoid is 640 units squared
Hope this helps!

Answer:
Area of the sector = [tex]\frac{\pi }{8}[/tex] cm²
Step-by-step explanation:
Measure of the given arc = 45°
Central angle formed by the arc = 45°
Formula to be used,
Area of the sector bounded by the arc = [tex]\frac{\text{Central angle}}{360}\times \pi r^{2}[/tex]
Here, r = radius of the circle
Area of the sector = [tex]\frac{45}{360}(\pi)(1)^2[/tex]
= [tex]\frac{\pi }{8}[/tex] cm²

The diameter of a circle is 34 feet. What is the circle’s area?
Use 3.14 as pi
The radius of the circle is 17 feet. Then the area of the circle is 907.46 square feet.
What is the area of the circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let r be the radius of the circle. Then the area of the circle will be given as,
A = πr² square units
The diameter of the circle is 34 feet. Then the radius of the circle is calculated as,
r = 34 / 2
d = 17 feet
The area of the circle is calculated as,
A = πr²
A = 3.14 x 17 x 17
A = 907.46 square feet

Range includes all but what
Several items in a store are on sale. Complete the table with the correct prices.
Original Price
Percent of Discount
Sale Price
$60 20% __?
$140 65% __?
__? 40% $54.60
__? 10% $10.80
Answer:
1. $48
2.$49
3.$91
4.$12
Step-by-step explanation:
For 1 and 2
To find the sale price, you find out how much is the percentage of the original price. Example :
(20/100)/60 = $12
So $12 is the discount
thus sales price will be $60-$12=$48
Same thing for no.2, find the amount of the percentage and subtract it from the original price
For 3 and 4
To find the original price
1. Subtract the percentage from 100%
2. Multiply the sales price by 100
3. Divide the ans from no.2 by ans from no.1
Example :
100%-40%=60%
$54.60×100=5460
$5460÷60%= $91 (original price)
Same thing for no.4
