What is the range in the function f(x) = 2x + 5 when the domain is {-2,-1, 3)?
PLEASE HELP 25 POINTS
Answer:
Range: {1, 3, 11}
Step-by-step explanation:
To find the range, just substitute the inputs into the function to find the outputs.
f(-2) = 2(-2) + 5
f(-2) = -4 + 5
f(-2) = 1
f(-1) = 2(-1) + 5
f(-1) = -2 + 5
f(-1) = 3
f(3) = 2(3) + 5
f(3) = 6 + 5
f(3) = 11
So the range is: {1, 3, 11}.

[tex]\huge\boxed{\tt{SSS}}[/tex]
Step-by-step explanation:
SSS (Side-Side-Side) Postulate can be used to prove the two triangles congruent.
Here's why:
Whole figure is a parallelogram which means that opposite sides are parallel and equal (or congruent).
So, Two of the sides can be proved congruent by that way.
The third side is common in both of the triangles which means that the third side is also congruent.
Hence, the two triangles are congruent by SSS postulate.

Find the values of x and y in the isosceles triangle
Answer:
X = 66 y = 48
Step-by-step explanation:
base angles of an isosceles are the same so x is 66
Angles in a triangle add up to 180
66 + 66 = 132
180 - 132 = 48
could anyone help me find Y? thanks!
Answer:
y = 42°
Step-by-step explanation:
The third vertex in the triangle with y is adjacent to a right angle, thus is right.
The sum of the 3 angles in a triangle = 180°, then
y = 180° - (90 + 48)° = 180° - 138° = 42°

Answer:
Not Linear
Step-by-step explanation:
A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degrees of the variables in the equation violate the linear equation definition, which means that the equation is not a linear equation.
Answer:
That equation is nonlinear.

I believe the answer is 22.5
Step-by-step explanation:
i think so because how you solve this is you take 6 and divided it by 4 and the ratio is 4:6 so it's a 1.5 difference if u divide so you then take 15 and times it by that same 1.5 and get 22.5

Are the graph of 4x-3y=9 and y=3/4x+7 parallel, perpendicular, or neither? Explain.
Answer:
Neither
Step-by-step explanation:
In this question, we have to verify if the equations are parallel, perpendicular, or neither to each other.
Turn the first equation into slope-intercept form so we can get a better understanding:
4x - 3y = 9
Subtract 4x from both sides.
-3y = -4x + 9
Divide both sides by -3.
y = 4/3x - 3
Now lets compare both lines:
y = 4/3x - 3
y = 3/4x + 7
Since the slopes have to be the same in order for the lines to be parallel, we can see that the lines are NOT parallel.
We also know that in order for the lines to be perpendicular, one has to be positive and the other has to be negative. In this case, they both are positive. This means that the lines are NOT perpendicular.
This means that our answer would be neither.
What is the image of the point (-3,-5) after a rotation of 180° counterclockwise about the origin?
Under a rotation of
180
∘
about the origin
a point (x ,y) → (-x ,-y)
hence (-3 ,4) → (3 ,-4)
The point (-3,-5) after a rotation of 180° counterclockwise about the origin changes to (3, 5).
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
We also know that when a point P(x, y) is rotated 180° about the origin it changes to ( -x, - y).
Given, Point (-3,-5) after a rotation of 180° counterclockwise about the origin.
∴ The new coordinates of the points are (3, 5).

A pair of shoes that normally cost $30 have their price reduced by 25%. What is the sale price of the shoes?
Answer:$22.50
Step-by-step explanation: you save $7.50
Sale price of shoes = $22.5
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, we have to divide the given number by the whole number and multiply by 100.
Given,
Cost of shoes = $30
Discount on shoes = 25%
Discount = (25/100) × 30
Discount = 750/100
Discount = $7.5
Sale price = Cost - discount
Sale price = $30 - $7.5
Sale price = $22.5
Hence, $22.5 is the sale price of shoes.

Find the area of each figure. Round to the nearest hundredth where necessary.
The area of the first figure is 629.86 sq. meters and for the second figure, the combined area would be 430.18 629.86 sq. meters.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
For the first figure, we need to find the area of the semicircles and the area of the rectangle, then we get the combined area that gives the area of the figure.
The length of the rectangle is 28m. we can see that the diameter of the semicircle is equal to half of the length of the rectangle.
So. D = 14m and radius = 7m
The area of the 2 semicircles = [tex]\pi r^2[/tex]
= π x 7 x 7
= 49π sq. meter
The breadth of the rectangle = 24 - r
= 24 - 7
= 17m
The area of the rectangle = length × Width
= 28 x 17
= 476 sq. meter
The combined area = 629.86 sq. meter
B. The area of the 2 semicircles = [tex]\pi R^2[/tex] + [tex]\pi r^2[/tex]
= π ( 11 x 11 + 4 x 4)

i need to find the slopes from two points!show work.i don’t know how to do this
Answer:
4
Step-by-step explanation:
Ok.....Since I can't graph it, we can make a table
x y
3 9
1 1
From 9 to 1, you subtract 8 (this is for the y section)
From 3 to 1, you subtract 2 (this is for the x section)
Now all you have to do is divide the y with the x
y/x = 8/2 = 4
And 4 will be your slope for these two points.

Show your thinking.
HELPPPPP!!!!
Answer:
A recipe uses 250 mL of milk for every 300 g of flour.
For making a bigger batch using 600 g of flour, let the amount of milk be x mL.
Now we should solve for x
According to the above problem,
[tex] \frac{250}{300} = \frac{x}{600} \\ x = \frac{600 \times 250}{300} \\ \boxed{ x = 500}[/tex]

Reflect this figure across the y-axis:
Answer:
The coordinates of the image triangle will be:
A'(-1, 1)B'(-1, 3)C'(-3, 3)Please also check the attached figure.
The green triangle represents the image triangle.
Step-by-step explanation:
We know that when we reflect a point across the y-axis, the y-coordinate remains the same but the x-coordinate reveres its sign.
Thus,
The rule of reflection of the point P(x, y) across the y-axis is:
P(x, y) → P'(-x, y)
In the attached figure, let the coordinates of the triangle are:
A(1, 1)B(1, 3)C(3, 3)Using the rule of reflection across the y-axis:
P(x, y) → P'(-x, y)
Thus, the coordinates of the image triangle will be:
A(1, 1) → A'(-1, 1)
B(1, 3) → B'(-1, 3)
C(3, 3) → C'(-3, 3)
Therefore, the coordinates of the image triangle will be:
A'(-1, 1)B'(-1, 3)C'(-3, 3)Please also check the attached figure.

Answer:
She will save [tex]\$24.44[/tex] by driving.
Step-by-step explanation:
Given: Jocelyn lives in Granite Falls. She wants to visit Megan in Spokane Valley. She can fly from Seattle to Spokane for [tex]\$96.20[/tex] round trip or she can drive a total of [tex]650[/tex] miles round trip. If her car gets [tex]25[/tex] miles per gallon, and gas costs [tex]\$2.76[/tex]/gallon.
To find: how much money will she save by driving?
Solution:
The total cost for flying Seattle to Spokane is [tex]\$96.20[/tex].
Now, in order to find how much money will she save by driving, we need to first find the total cost for driving a total of [tex]650[/tex] miles round trip.
So, total distance [tex]=650[/tex] miles.
Car covers [tex]25[/tex] miles per gallon.
So, to cover [tex]650[/tex] miles, [tex]\frac{650}{25} =26[/tex] gallons of gas is required.
Now, gas costs [tex]\$2.76[/tex]/gallon.
Therefore, total charge [tex]=26\times2.76=\$71.76[/tex].
So, total money saved[tex]=\$96.20-\$71.76=\$24.44[/tex]
Hence, she will save [tex]\$24.44[/tex] by driving.
