A graph where the horizontal axis shows time (t), numbered 1 to 4, and the vertical axis shows height (h) numbered 10 to 60. Solid circles appear at point (0, 48), point (1, 64), point (3, 0). A solid curved line connects all 3 points. Leon throws a ball off a cliff. The graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds. What is the domain? {t| 0 ≤ t ≤ 3} {t| 0 ≤ t ≤ 48} {t| 0 ≤ t ≤ 64} {t| all real numbers}

There are 7 more sweaters than shirts in the drawer. There are 15 sweaters and shirts in the drawer in all. How many shirts are there in the drawer? Let S represent the number of shirts. Which equation represents the situation
Answer:
7 + 2s = 15
4 shirts
Step-by-step explanation:
Let's say w denotes sweaters and s denotes shirts.
Since there are 7 more sweaters than shirts:
w = 7 + s
There are a total of 15 sweaters and shirts in all, so:
w + s = 15
Substitute 7 + s in for w in the second equation:
w + s = 15
7 + s + s = 15
7 + 2s = 15
Solving for s:
7 + 2s = 15
2s = 15 - 7 = 8
s = 8/2 = 4 shirts
Thus, the equation is 7 + 2s = 15, and there are 4 shirts.

Answer:
AC = 7.5 cm
Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{AC}{DE}[/tex] = [tex]\frac{BC}{DE}[/tex] , substitute values
[tex]\frac{AC}{3.5}[/tex] = [tex]\frac{7+8}{7}[/tex] , that is
[tex]\frac{AC}{3.5}[/tex] = [tex]\frac{15}{7}[/tex] ( cross- multiply )
7AC = 52.5 ( divide both sides by 7 )
AC = 7.5 cm

Mrs. Bowman spent $110 to rent a popcom machine for the school
carnival and $75 to buy popcorn, oil, and other supplies. If she sold
263 bags of popcorn for $1.50 each, how much money did she make after paying for the machine and the supplies?
Answer:
200 minutes I am getting poi tea yayyyy
Answer:
$209.50
Step-by-step explanation:
First, find how much she made selling the popcorn:
263(1.5)
= 394.50
Then, find how much she spent on supplies and the machine:
110 + 75
= 185
Subtract the expenses from the profit:
394.50 - 185
= $209.50

9. Krista and Emily wrote an equation of a line that is parallel to the line y = 3x - 1 and passing
through the point (5,9). Is either of them correct? Explain your reasoning?
Krista:
9 = 3(5) + b
9 = 15 + b
-6 = b
y = 3x - 6
Emily:
y- 9 = 3(x - 5)
y- 9 = 3x - 15
y = 3x - 24
Answer:
Explanation:
Step-by-step explanation:
Hey there!
The equation, of a st. line that passes through point (5,9) is,
[tex](y - y1) = m1(y - y1)[/tex]
Put the values,
[tex](y - 9) = m1(x - 5)[/tex]
It is 1st equation.
Now, another equation is,
y = 3x-1.........(ii)
Comparing the equation with y = mx+c.
Slope (m2)= 3
As per the parallel lines,
m1=m2=3
Putting,
the value of m1 in equation(i)
(y-9)= 3(x-5)
y-9= 3x - 15
y = 3x - 6.
So, Krista equation is correct.
Hope it helps...

Write the algebra expression: six times the sum of four and a number
Answer:
6(4+x)
Step-by-step explanation:
Answer:
6(x+4)
Step-by-step explanation:
We want to write an algebraic expression for "six times the sum of four and a number"
Let's break this down.
The sum of four and a number:
The words "sum" indicates addition. We can call " a number" x, since it is unknown.
So, the sum of four and a number is: (x+4).
Six times:
The word "times indicates multiplication. We are multiplying six and the sum of four and a number.
So, we have: 6(x+4)
The algebra expression for "six times the sum of four and a number" is 6(x+4)

−20x+10=−12x−6
Step 2: Add 12x to both sides.
−20x+10+12x=−12x−6+12x
−8x+10=−6

Hugh bought some magizines that cost 3.95 each and some books that cost 8.95 each. He spent a total of 47.65.If Hugh bought 3 magazines,how many books did he buy
Answer:
4 books
Step-by-step explanation:
We are told that: Hugh bought some magazines that cost 3.95 each
Hugh bought 3 magazines.
Hence, total cost of magazines = 3 magazines × 3.95
= 11.85.
Total cost of magazines = 11.85
From the question, we know that, the total amount Hugh spent = 47.65
Hence, The total cost for books =
Total amount spent - Total cost of magazines
= 47.65 - 11.85
= 35.80
Therefore, the total cost of books = 35.80
We are told in the question that the cost of books is 8.95 each or 8.95 per book.
Hence, the number of books that Hugh bought is calculated as :
35.80/8.95
= 4 books
Therefore, Hugh bought 4 books

Solve the following equation, answer as a reduced, mixed number. Then place the correct number in the box provided. 4(3 - 2x) = 15
Answer:
x = -3/8
Step-by-step explanation:
4(3 - 2x) = 15
Distribute
12 -8x = 15
Subtract 12 from each side
12-8x-12 =15-12
-8x =3
Divide by -8
-8x/-8 = 3/-8
x = -3/8
The correct answer is: -3/8
If a and B are the zeros of the quadratic polynomial f(x) = x2- 5x + 4 find the value of 1/a+1/b-2ab
Answer:
-27/4Step-by-step explanation:
Given the quadratic polynomial given as g(x) = x²- 5x + 4, the zeros of the quadratic polynomial occurs at g(x) = 0 such that x²- 5x + 4 = 0.
Factorizing the resulting equation to get the roots
x²- 5x + 4 = 0
(x²- x)-(4 x + 4) = 0
x(x-1)-4(x-1) = 0
(x-1)(x-4) = 0
x-1 = 0 and x-4 = 0
x = 1 and x = 4
Since a and b are known to be the root then we can say a = 1 and b =4
Substituting the given values into the equation 1/a+1/b-2 ab , we will have;
= 1/1 + 1/4 - 2*1*4
= 1 + 1/4 - 8
= 5/4 - 8
Find the Lowest common multiple
= (5-32)/4
= -27/4
Hence the required value is -27/4
