Options:
A) 20 yards per $30.00
B) 40 yards per $45.00
C) 50 yards per $70.00
C) 65 yards per $85.00
Think if buying something at the lowest cost which gives more.
1 yard per $1.00, sounds like a good deal.
20 yards per $30.00 which mean $10.00 more.
40 yeards per $45.00 which mean $5.00 more.
50 yards per $70.00 which mean $20.00 more.

Todd runs 3.5 miles around the
school track. Each lap is 0.25 mile.
What equation can be used to find
how many laps around the track
Todd runs?
Answers
Hi!
We can use x to represent the number of miles that Todd runs.
He runs a total of 3.5 miles, and each lap is 0.25 miles.
Therefore:
3.5 = 0.25x
The question simply asks for an equation, so there is no need to calculate how many laps he takes.
If f (x) = 3x² - x, find f (-2).
O 10
O 14
O 38
Answers
Answer:
The value of f(-2) is equal to 14.
Step-by-step explanation:
Let's define what we are given:
f(x) = 3x² - xf(-2)Recall from function notation that f(-2) is equal to x = -2 for f(x). That means we can substitute in x = -2 into f(x):
f(-2) = 3(-2)² - (-2)From here, we can evaluate the function expression using BPEMDAS (Brackets, Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction):
f(-2) = 3(-2)² - (-2)f(-2) = 3(4) - (-2)f(-2) = 3(4) + 2f(-2) = 12 + 2f(-2) = 14∴ f(-2) = 14.
Hope this helps!
F(x)=3x^2 -x
F(-2)= 3(-2)^2 -(-2)
= 3(4) +2
= 12 + 2
= 14

Kara scores 3 points when she completes the first level of a video game. At each level after that she scores 3 times the amount awarded at the previous level. If she completes 4, how many points does she score in all?
Answers
Answer:
120
Step-by-step explanation:
If Kara earns 3 times as many points completing the next level than she earned the previous level, to find how many points she earned at level 3, triple the amount of points earned in level 2, which is 9.
9 × 3 = 27
We can confirm this is the correct value by multiplt 27 by 3 to see if it equals 81, which it ineed does.
To find how many points she scored in all, find the sum by adding all of the points together.
3 + 9 + 27 + 81 = 120
She scores 120 points in all.

Which pair of triangles can be proven congruent by SAS?
Answers
Answer:
Second option
Step-by-step explanation:
They have two congruent pairs of sides and one congruent pair of angles.
The triangles B can be proven congruent by the SAS theorem
What are Congruent Triangles?Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
The three sides are equal (SSS: side, side, side)
Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)
Given data ,
From the Option B) , we get
Let the first triangle be ΔABC
Let the second triangle be ΔBDE
Now , the measure of side AB = measure of side BD
And , the measure of side AC = measure of side BE
And , the measure of ∠ABC = measure of ∠DBE
Therefore , Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
Hence , the triangles are congruent by SAS theorem

X=1 Plug X into equation Y=3(1)+2 then Y = 5 that's point (x,y) = ( 1,5)
X=2 Plug X into equation Y=3(2)+2 then Y = 8 that's point (x,y) = (2,8)

What is the value of x is the solution to the equation -8(x + 3) = -10x - 5?
Answers
Answer:
x = 19/2
Step-by-step explanation:
1) Distribute
-8x-24=-10x-5
2) Add 24 to both sides
-8x-24+24=-10x-5+24
3) Simplify
- Add the numbers
-8x = -10x - 5 + 24
- Add the numbers
-8x = -10x+19
4) Add 10x to both sides
-8x+10x=-10x+19+10x
5) Simplify
- Combine like terms
2x = -10x+19+10x
-Combine like terms
2x=19
6) Divide both sides by the same factor
2x/2 = 19/2
7) Simplify
- Cancel terms that are in both the numerator and denominator
x = 19/2

Answer:
[tex]-\frac{1}{4}[/tex]
Step-by-step explanation:
Work out fg(x)
To work out fg(x), put the g function into the f function so, the x in f(x) is equal to the x+1 (from the g function) so:
[tex]2(x+1)^{2} = 2 (x^{2} +2x+1) = 2x^{2} + 4x +2[/tex]
So fg(x) = [tex]2x^{2} + 4x +2[/tex]
Work out gf(x)
Do this by substituting the f(x) equation into the g(x) which is:
[tex](2x^{2} )+1[/tex]
So gf(x) = [tex](2x^{2} )+1[/tex]
Work out x
And since fg(x) = gf(x),
[tex]2x^{2} + 4x +2[/tex] = [tex](2x^{2} )+1[/tex]
4x = -1
x =[tex]-\frac{1}{4}[/tex]
