wrong, each of which were worth 4 points. On
the same test, she earned 5 extra credit points.
What was the change it point value from missed
questions and extra credit? Write your answer
as an integer.
Answer:
-7
Step-by-step explanation:
She lost 12 points, 3 * 4 = 12, and she gained 5 points, so -12 + 5 = 5 - 12 = -7

Which of the following are needed to make an expression?
A. variable(s)
B. number(s)
C. equal sign
D. operation(s)
Answer:
variables is the correct answer
Answer:
ALL OF THE ABOVE
Step-by-step explanation:
An expression is a syntactic construct. It must be well-formed: the allowed operators must have the correct number of inputs in the correct places, the characters that make up these inputs must be valid, have a clear order of operations, etc.
It can be all of the above too. because everything is needed to make an expression.

Gavin needs 7/8 gallons of paint to finish painting his deck. He has 0.06 gallon of paint. Does he have enough. Why or why not?
I don't understand this
plz answer 3,4 and 5
Answer:
3. Since it asked us to write question 3 in the from y=mx + c
m is the gradient
c is the intercept on y axis or where the line enters or cuts the y axis. This can be seen from the diagram. The line cuts the y axis at "9". (Check the diagram for this).
Now to find m.
Pick points on the line
Say (1,6) and (2,3)
Gradient = m = y2 - y1/(X2 - X1)
x1 = 1
y1 =6
x2 = 2
y2 = 3
Substituting into that formula
m = 3 - 6/2 - 1
m= -3/1
m= -3.
Since we've gotten what we need
y=mx + c
Y= -3x + 9.
4. 4x + 2y = 12
Rearranging by making y subject to suit the eqn...y=mx + c
you have
m is the gradient and c is the intercept.
2y = -4x + 12
Divide through by 2
y= -2x + 6
y=mx + c
By comparing...
m==gradient = -2
c== Intercept = 6
5). Doing the same thing we did above
-6x + 3y =21
Making y subject
3y = 6x + 21
Divide through by 3
y= 2x + 7
y=mx + c
m==gradient =2
c==Intercept =7.
Hope this helps.
Have a great day!

Answer:
C
Step-by-step explanation:
First find the area of the entire figure.
L= 36
W = 20
Area = 36 * 20 = 720
Find the area of the left right triangle.
Height = 20
Base = 1/2 * 36 = 18
Just as an aside, let me be a little grumpy for a moment. You should never have to guess what a dimension is on a diagram. It's sloppy. However for this problem you have no choice. But you could think to complain to your teacher.
Area = 1/2 * base * height
Area = 1/2 * 18 * 20 = 180
Find the area of the bottom right triangle.
The height is 1/2 20 = 10
The base is 36
Area of the lower triangle = 1/2 * 36 * 10 = 180
Area of the shaded figure = 720 - 180 - 180 = 360

A cylinder is sliced perpendicular to its circular base. What shape will the cross section be?
Answer:
RECTANGLE
Explanation:
Answer:
Rectangle
Step-by-step explanation:
If its sliced perpendicular from its circle base, that means its cutting vertically from it since perpendicular lines form a 90 degree angle.
The Math Club at Dawn's school had a Math Carnival. At her booth, Dawn set up three scales with baseballs, tennis balls, and soccer balls, as shown in the picture above. Each soccer ball weighs 12 ounces.
Contestants tried to determine the weight of each kind of ball.
How much does each kind of ball weigh?
[Assume that all the soccer balls weigh the same, all the baseballs weigh the same, and all the tennis balls weigh the same.]
1.How does each ball weigh.
2.How much does each tennis ball weigh.

1.) 7+7/9x=−42 2.) 4x+1=−15 3.)−4(x−3)=−40
Answer:
1) x= -1/27
2) x=-4
3) x=13
Step-by-step explanation:
1) 7+7/9x= = -42
14/9x= = -42
14/9x X 9x= -42 X 9x
14= -378x
-378x= 14
-378x/-378= 14/-378
x= -1/27
2) 4x+1=−15
4x+1-1=-15-1
4x=-16
4x/4= -16/4
x=-4

Find the Area of the shape
(Area of Composite Shapes)
Answer:
223.5 Km
Step-by-step explanation:
Area = Length x Width
Solving for Square Shape
8 · 6 = 48 km
Area = Length x Width
Solving for Rectangle Shape
9 · 14 = 126 km
Area = Length x Width ÷ 2
Solving for Triangle Shape
11 · 9 = 99 ÷ 2 = 49.5 Km
48 + 126 + 49.5 = 223.5 Km
The quadratic function h(t) = −4.9t^2 + 50t + 2 represents the height, in meters, of a toy rocket t seconds after launch. How many seconds will it take the toy to reach the ground? State your answer to the nearest whole second.
Answer:
The toy reaches the ground in 10 sec
Step-by-step explanation:
When the rocket hits the ground, h becomes zero (0). Thus, our problem here is to solve the equation h(t) = −4.9t^2 + 50t + 2 = 0,
Because of the fractional coefficient -4.9, it's best to use the quadratic equation here. The coefficients of the t terms are {-4.9, 50, 2}. Thus,
the discriminant is b^2 - 4ac = 50² - 4(-4.9)(2) = 2539.2, and the square root of this is 50.39.
The quadratic formula is as follows:
-b ± √discriminant
t = -------------------------------
2a
which here is:
-50 ± 50.39
t = ------------------------ Since t represents time, only the positive result
-9.8 is relevant here; it is 10.24 sec,
which rounds off to 10 sec
The toy reaches the ground in 10 sec
A football player attempts to kick a football across a field. The path of the football can be modeled by the function h(x) = − 1/225 x^2 + 2/3 x, where x is the horizontal distance from the kick, and h(x) is the height of the football above the ground, when both are measured in feet. How far from the kicker will the football land?

2. At a fair, each person can spin two wheels of chance. The first wheel has the numbers 1, 2, and 3. The second wheel has the letters A and B. (d) List all the possible outcomes of the compound event. (e) If you spin both wheels, what is the probability that you get either a 1 or an A? Explain.
Which equation represents a linear function?
A. y= 1/2 x to the second power - 5
B. y= 1/2 x to the third power - 5
C. y= 1/2 x + 5
D. y=(1/2) to a power - 5
Answer:
C. y = 1/2x + 5
Step-by-step explanation:
For A. and B. x to a power of something, if x is at a power of anything, like x^2 or x^3, then it is not linear.
For D. it doesn't even have x in it, so basically y equals a number.
C. is a linear equation, y = 1/2x + 5
