Select all equations that have graphs with the same y-intercept.
y = 3x - 8
y = 3x - 9
y = 3x + 8
y = 5x - 8
y = 2x - 8
y = (1/3)x - 8
The equations that have graphs with the same y-intercept are:
y = 3x - 8y = 5x - 8y = 2x - 8y = (1/3)x - 8To determine which equations have graphs with the same y-intercept, we need to look for equations that have the same constant term when written in the form y = mx + b, where m represents the slope and b represents the y-intercept.
The y-intercept is the value of y when x is equal to 0. In other words, it is the point where the graph intersects the y-axis.
Let's compare the equations and their constant terms:
y = 3x - 8 (Constant term: -8)
y = 3x - 9 (Constant term: -9)
y = 3x + 8 (Constant term: 8)
y = 5x - 8 (Constant term: -8)
y = 2x - 8 (Constant term: -8)
y = (1/3)x - 8 (Constant term: -8)
From the comparison, we can see that the equations y = 3x - 8, y = 5x - 8, y = 2x - 8, and y = (1/3)x - 8 all have the same constant term of -8. This means that their graphs will have the same y-intercept, which is -8.
Therefore, the equations that have graphs with the same y-intercept are:
y = 3x - 8
y = 5x - 8
y = 2x - 8
y = (1/3)x - 8

Billy and Tom are out to dinner. Their bill comes to a total of $100. They have a 15% off coupon but tax and tip must also be included. The tax is 6% and is applied before the 20% tip. If Billy and Tom want to split the bill, how much will they each have to pay?
1. How much is their bill after the coupon has been applied?
2. With the coupon applied, what is their new total (including the tax)?
3. With their new total, Billy and Tom can now determine the tip for their server. What is the final total, including the tip?
4. What will Billy and Tom each have to pay to split the bill evenly?
Please answer labeled with numbers! thankyou!
Answer:
1. $85
2. $90.10
3.$108.12
4.$54.06
Step-by-step explanation:
100-15=85 (15% of 100 is 15)
6 percent of 85 is 5.10. So 85 + 5.10=90.10
20 percent of 90.10 is 18.02. So add that to the total. 90.10+18.02=108.12
Now divide by 2 to get how much they each will pay 108.12/2 = 54.06
Colton gave out a survey to some students in his school about their favorite color. 470 of those surveyed said their favorite color was blue. If 94% of the students surveyed said their favorite color was blue, how many students were surveyed in total?

Brainly annie has 2 bags of apples and 5 single apples eva has 1 bag of apples and 11 single apples they have the same amount of apples how many apples so they have in total
Answer:
34 apples
Step-by-step explanation:
To answer: try setting up each of the equations for Annie and Eva.
Annie: 2(bag) + 5
Eva: 1(bag) + 11
Those two equations equal each other. So set that up:
2(bag) + 5 = 1(bag) + 11
Now solve for the size of the bag.
2(bag) - 1(bag) = 11 - 5
1(bag) = 6 apples
Now substitute 6 back into either equation to determine number of apples.
Annie: 2(6) + 5 = 12+5=17
They each have 17, so there are 34 apples in total.
solve the equation and show the work please

If a triangle has 2 sides of 8 and 11 what could the third side be
Answer:
Any value between 3 and 19 may be the measure of third side.
Step-by-step explanation:
If three sides of a triangle are a, b, and c, possible measures of the sides of a triangle will be.
1). a + b > c
2). b + c > a
3). a + c > b
If a = 8, b = 11,
1). 8 + 11 > c
c < 19
2). 11 + c > 8
c > 8 - 11
c > (-3)
3). 8 + c > 11
c > 11 - 8
c > 3
Therefore, by combining the given inequalities,
3 < c < 19
Any value between 3 and 19 may be the measure of third side.

7. The two equations have different solution steps. Do they have the same solution?
Use the distributive property to show why this answer makes sense.
Answer:
Yes, they have the same solution.
Step-by-step explanation:
Both of these equations have the same solution, just different steps.
To solve Ravi's equation, first we use the distributive property.
2(x+14) = 40
Multiply 2 by x and 14
2x + 28 = 40
Subtract 28 from both sides.
2x + 28 - 28 = 40 - 28
2x = 12
Divide by 2 on both sides.
2x/2 = x
12/2 = 6
so x = 6.
Fran's equation is the same equation as Ravi's second step.
Her equation of 2x + 28 = 40 is Ravi's after distributing 2.
Answer:
2(x+14)=40
2(x+14)=40
÷2 ÷2
x+14=20
-14 -14
x=6
2x+28=40
-28 -28
2x=12
÷2 ÷2
x=6

18 bottles of water cost $9. How much does it cost for one bottle of water? How much bottles can you buy with $6?
Answer:
Water cost 2$ you can buy 3 water bottles with 6$
Step-by-step
I did myself
Answer:
one bottle of water is 0.5 dollars. You can buy three bottles of water for $6
Step-by-step explanation:
since 9 divided by 18= 0.5, this is how it goes
18 bottles broken up into sections of one (one bottle in each section)
so you have to break up the dollars into cents to put an equal amount with each bottle. So you get 100 pennies for each dollar. There's only 9 dollars, so you split the pennies (that you broke from the 9 dollars) and put one in each section (each section still has one bottle) so each bottle with get one more penny with every round. The bottles take turns getting pennies. After you do all of them you will get 0.5 dollars for each bottle so that's how much the bottles cost.
The bottles cost 0.5 dollars.
Now we do this with 6 dollars instead of 9. You now know that each bottle cost 0.5 dollars so you have to do this
0.5 x 6 which = 3.
You can buy 3 bottles with $6.
I hope this helps!

Answer:
[tex]\Huge\boxed{\$ 12.12}[/tex]
Step-by-step explanation:
In order to find how much credit is left after 92 minutes, we need to
1. Figure out the equation that describes this graph (since we don't know the y-intercept)
2. Find the credit remaining after 92 minutes using the equation formed.
Figuring out the equation of this graph:First things first is to figure out the slope of this graph. Since this is a linear function, the slope will remain constant, and we can note something about slope here.
The slope of a line will be it's change in x divided by its change in y, often referred to with a formula.
[tex]\frac{\Delta y}{\Delta x}[/tex]
Since we know two points on this graph, we can find the changes in the x and y then divide for the slope.
Since minutes used is the x, and credit left is the y, we have two points.
(41, 19.26) and (68, 15.48).
The change in y is -3.78, as [tex]19.26-15.48=3.87[/tex], and we decreased, so -3.78.The change in x is 27 as [tex]68-41=27[/tex], and we increased.The slope will then be [tex]\frac{-3.78}{27}[/tex] which comes out to be -0.14.
Now that we know the slope, that means our equation will look something like [tex]y = -0.14x+b[/tex] - however, we still have b to solve for!
To solve for it, we can substitute one of our points in - let's do (41, 19.26) - to the equation and solve for b.
[tex]19.26 =-0.14 \cdot 41 +b[/tex] [tex]19.26 = -5.74+ b[/tex] [tex]b = 19.26+5.74[/tex] [tex]b = 25[/tex]Now that we know that b = 25, we can plug it into our equation, making the final equation that represents this scenario
[tex]y = -0.14x+25[/tex]
Solving for 92 minutesNow that we know the equation to our graph, we can substitute in 92 minutes as the x value to find our y value (credit left).
[tex]y = -0.14 \cdot 92 + 25[/tex] [tex]y = -12.88+25[/tex] [tex]y =12.12[/tex]Therefore, after 92 minutes, the amount of credit left is $12.12
Hope this helped!
Question 2 (1 point)
What is the value of x if AABC is equilateral?
Answer:
x= 2
Step-by-step explanation:
Given that,
AB = 7.5x
BC = 6x+3
AC = 10x-5
ΔABC is an equilateral triangle.For an equilateral triangle, all sides are equal. ATQ,
AC = BC = AB
10x-5 = 6x+3
Taking like terms together
10x-6x = 5+3
4x = 8
x = 2
Hence, the value of x is equal to 2.

Write 70 cm as a fraction of 4.2 m. Give your answer in its simplest form.
Answer:
1/6
Step-by-step explanation:
First convert 4.2m to cm
100cm = 1m
x = 4.2m
x = 4.2 * 100
x = 420cm
70cm to 420cm = 70/420
70/420 = 7/42
7/42 = 1/6
Hence 70 cm as a fraction of 4.2 m is 1/6
