Answer:
scale factor = 2.5 and b` is now (0,10) and c` is (-15, 25)
Step-by-step explanation:
You first want to divide -15 and -6, the x values of a and a`. this will give you the scale factor. then multiply every other number by the scale factor to get the points for b` and c`.

Answer:
A triangle is 180 degrees and you have a 30 and 50 angle so the third angle should equal 100. so the answer should be 45 and here's why
Step-by-step explanation:
Subtract 10 from both sides
2x+10=100
2x+10-10=100-10
Simplify
Subtract the numbers
2x=90
Divide both sides by the same factor
2x=90
2x/2 = 90/2
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
x=45
Solution
45

Answer:
You would have a horizantal line with a y-intercept of 1.
Step-by-step explanation:
Answer: y is less than or equal to 1
Step-by-step explanation:
Whenever you see parentheses you should automatically think of P.E.M.D.A.S.
Step 1:
In order to get rid of the parentheses you will have to combine like terms, meaning that the 7 will need to be multiplied by whats inside the parentheses.
7 x y = 7y
7 x 2 = 14
Rewritten, your equation should look like this: 7y + 14 - 6 less than or equal to 15
Step 2:
Next, we need to get rid of the 6 which means that 6 should be added in order to cancel it out. 6 should also be added to the other side of the equation.
-6 + 6 = 0
15 + 6 = 21
Rewritten, your equation should look like this: 7y + 14 less than or equal to 21
Step 3:
In order to further balance out the equation, you will need to subtract the 14 from both sides of the equation.
14 - 14 = 0
21 - 14 = 7
Rewritten, your equation should look like this: 7y is less than or equal to 7
Step 4:
Finally, you should divide both sides by seven!
7y/7 = y
7/7 = 1
Rewritten, your equation should look like this: y is less than or equal to 1

what are three ratios that are equivalent to 4:3.
Answer:
8:6 , 12:9 , 16:12
Step-by-step explanation:
To find equivalent ratios is like finding equivalent fractions :
We simply multiply both numbers of the ratio by the same number.
You can also do the reverse to simplify a ratio.
4:3 × 2 = (4×2):(3×2) = 8:6
4:3 × 3 = (4×3):(3×3) = 12:9
4:3 × 4 = (4×4):(3×4) = 16:12
Therefore 3 ratios that are equivalent to 4:3 are :
8:6 , 12:9 , 16:12

What is the height of the square pyramid? Show work for full credit
A) 4
B) 8
C) 12
D) 16
Answer:
B
Step-by-step explanation:
Because the pythagorean theorem we know that s2 = r2 + h2, since r = a/2s2 = (1/4)a2 + h2, and s = √(h2 + (1/4)a2)
This is also the height of a triangle side
This table represents Una's check register. Her checking account had a balance of $1,568.45 on January 18. Use the information in the check register to determine the balance of Una's checking account after the transaction on February 7.
Answer:
$1187.22
Step-by-step explanation:
The balance was $1568.45 on 1/18 then she decided to withdraw $765.23 on 1/30, so we subtract 765.23 from 1568.45 which is 803.22 but then she added $384 to the account on 2/7 so we add 384+803.22 which equals to $1187.22, which would be the total balance on her account.
Answer:
$1,187.22
Step-by-step explanation:
After all of the Transactions, she will end up with $1,187.22
$1,568.45-$765.23= 803.22
$803.22+384=$1,187.22
Answer: $1,187.22

Carly placed 50 marbles in a bag. Fifteen of the marbles are pink, 8 marbles are black,
2 marbles are green, 18 marbles are clear, and 7 marbles are striped. Click and drag
the letters onto the probability scale to order the likelihood that the event will happen.
When you go into this problem, you want to figure out your marble ammount to 50 so in this case we will say C for color and 50 for the total ammount of marbles.
We know 15 are pink, 8 are black, 2 are green, 18 are clear, and 7 are striped
15P/50
8B/50
2G/50
18C/50
7S/50 for a total of 50 marbles
Now we use the chart to decide our awnsers
A. We know our propability of drawing a green and clear is 20/50 which if we simplify is a 2/5 ratio. If We put this in perspective 2/5 is rare and is unlikley to even.
B. We know a striped marble is 18/50 or 1.8/5 ratio which is mainly unlikely
C. We have 23/50 marbles that are black and pink, our propability is about 2.3/5 and gives us an even chance to get one of these
D. We know we have 33/50 marbles that are pink and clear and gives us a 3.3/5 chance of getting one of these and gives us an even to likely chance of getting one of these.
E. If we have a total of 17 marbles in these 3 colors, we have a 1.7/5 chance of getting one of these and is probably impossible to unlikey.

Gordon got a mountain bike for his birthday. when he took the bike out for a ride he biked 3/4 of a mile in 1/10 of an hour , at this rate how far would Gordon bike in 2 hours?
answer is needed asap
Answer: 7. 2/4
Step-by-step explanation:
3/4. Divided by 1/10
The distance that Gordon would bike is 15 miles.
What is the distance that Gordon would bike?The first step is to determine the average speed of the mountain bike. Average speed is how fast an object moves with respect to time.
Average speed = total distance / time
3/4 ÷ 1/10
3/4 x 10 = [tex]\frac{30}{4}[/tex] = 7[tex]\frac{1}{2}[/tex]
The formula to determine the distance he would cover given his speed is
Distance = average speed x time
7[tex]\frac{1}{2}[/tex] x 2
[tex]\frac{15}{2}[/tex] x 2 = 15 miles

Answer:
“A.”
Step-by-step explanation:
15 + 3x is the equation, so we need to have the 3 multiplying by “x” no matter what.
Answer “A.” 3(5+x) would give us 15+3x when the 3 is distributed to the 5 and the “x”
You are welcome :D
Answer:
[A] 3(5+x)
Step-by-step explanation:
To Find which expression is equivalent to 15 + 3x
We can simplify to see:
Start with [A] 3 ( 5 + x )
3 · x = 3x
3 · 5 = 15
3x + 15
True
Next we have [B] 5 ( 3 + x)
5 · x = 5x
5 · 3 = 15
5x + 15
False
Then we have [C] 3 ( 5 + 3x)
3 · 3x = 9x
3 · 5 = 15
9x + 15
False
Finally, we have [D] 5 ( 3 + 3x)
5 · 3x = 15x
5 · 3 = 15
15x + 15
False
3x+15 is the same thing as in 15 + 3x
Thus, [A] 3 ( 5 + x) is the correct answer.
