Step-by-step explanation:
Use the system of equations to answer the questions.
5x+4y=3
y=−2x+6
The value of y from the second equation is substituted back into the first equation. What is the resulting equation?
What is the value of x?
What is the value of y?
Answers
The resulting equation after substitution is
5x + 4(-2x + 6) = 3
quite literally you replaced y with what it equals (as said in the second equation)
you then distribute the 4 within the parenthesis
5x + -8x + 24 = 3
You make it easier
5x - 8x +24 = 3
you combine like terms
-3x + 24 = 3
you subtract 24 from both sides
-3x = -21
you divide both sides by -3
meaning x = 7
you then use that value x = 7 and substitude it for the x in the other equation.
That makes the y equation
y = -2(7) + 6
you then solve
y = -14+6
y = 6 - 14
y = -8
Replace y with -2x+6 in the first equation
5x+4(-2x+6)=3
Then solve for x
First, distribute 4
5x-8x+24=3
Combine like terms
-3x+24=3
Subtract 24 from both sides
-3x=-21
Isolate x by dividing -3 to both sides
x=7
Replace x with 7 in either equation and then solve
y=-2(7)+6
Multiply -2 by 7
-14+6
Add
y=-8

Martin would save $1.01 per game by going to PC Richard & Son
Step-by-step explanation:
To solve this question, you have to divide the amount of money by the amount of games. You already know Best Buy's price for 1 game here (59.99).
Since the price is 117.96 for 2 games at PC, you can do
117.96÷2=58.98
59.99-58.98= $1.01
Oh, and even if you do 294.90÷5, you'd get the same thing.

cam hits the bullseye in 8 darts out of 15 throws. what is the experimental probability that came next throws will hit the bullseye?
Answers
Answer:
A darts player practices throwing a dart at the bull’s eye on a dart board. Her probability of hitting the bull’s eye for each throw is 0.2.
(a) Find the probability that she is successful for the first time on the third throw:
The number F of unsuccessful throws till the first bull’s eye follows a geometric
distribution with probability of success q = 0.2 and probability of failure p = 0.8.
If the first bull’s eye is on the third throw, there must be two failures:
P(F = 2) = p
2
q = (0.8)2
(0.2) = 0.128.
(b) Find the probability that she will have at least three failures before her first
success.
We want the probability of F ≥ 3. This can be found in two ways:
P(F ≥ 3) = P(F = 3) + P(F = 4) + P(F = 5) + P(F = 6) + . . .
= p
3
q + p
4
q + p
5
q + p
6
q + . . . (geometric series with ratio p)
=
p
3
q
1 − p
=
(0.8)3
(0.2)
1 − 0.8
= (0.8)3 = 0.512.
Alternatively,
P(F ≥ 3) = 1 − (P(F = 0) + P(F = 1) + P(F = 2))
= 1 − (q + pq + p
2
q)
= 1 − (0.2)(1 + 0.8 + (0.8)2
)
= 1 − 0.488 = 0.512.
(c) How many throws on average will fail before she hits bull’s eye?
Since p = 0.8 and q = 0.2, the expected number of failures before the first success
is
E[F] = p
q
=
0.8
0.2
= 4.

Answers
Answer:
1/2 or 2
Step-by-step explanation:
If the original triangle length of Side A to C is 4, then the answer is two. If the original traingle length is Side A to C on the original triangle is 8, then the answer is 1/2.
The scale factor of the dilation is 1/2.
What is scale factor?Scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape. It is used to increase or decrease the size of an object. The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known.
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
Given:
Before dilation
AC= 8, BC= 10 abd AB= 6
After dilation
AC= 4, BC= 5 and AB= 3
Now, scale factor
Scale factor = Dimensions of the new shape / Dimensions of the original shape.
So,
scale factor = 4/8 or 5/10 or 3/6 = 1/2
Hence, the scale factor is 1/2.

Which statements about the figure are true? Select three options.
Vertical angles prove that Angle 2 is congruent to angle 5.
In the two similar triangles, Angle 1 and Angle 4 are alternate interior angles.
Vertical angles prove that Angle 3 is congruent to angle 6.
The triangles are similar because alternate interior angles are congruent.

You earn $56 walking your neighbor's dog for 8 hours. Your friend earns $36 painting your neighbor's fence for 4 hours.
What is your pay rate? And What is your friend's pay rate?
Answers
Answer:
Your pay rate is:
$ 7 per hour
Your friend's pay rate is :
$ 9 per hour
Explanation:
So if it takes you 8 hours to make $ 56 , you can just divide the total money earned by the time. So it would be 56 ÷ 8 which is 7 .
And if takes your friend 4 hours to make $ 36 , you can divide like we just did . So it would be 36 ÷ 4 which is 9 .
So you make $ 7 per hour and your friend makes $ 9 per hour.
