Answer:
C) 10+2h=5+4h
Step-by-step explanation:
I think it's C because it says the equation correctly. (Remember we don't know how many hours a persons going to be there so that would be h.)

If the ordered pair (a, b) satisfies the inequality. y > x-4, three of these statements are
true. Which statement is NOT true?
Answer:
If you subtract 4 from a, it will be greater than b
Step-by-step explanation:
Ok, so in order to solve this, it would be easier to substitute (a,b) into the equation:
b>a-4
Ok, next, you just have to work out each individual question to see which one is incorrect. You can immediately know it is the first one, and this is because we know that B is larger in this equation, but the problem says that subtracting 4 from a would be greater than b. This is incorrect, b is greater than 4-a, so the top left would be your answer.
Hope this helps!

Suppose the graph of a cubic polynomial function
has the same zeroes and passes through the
coordinate (0, -5).
Describe the steps for writing the equation of this
cubic polynomial function.
DONE
Answer:
Use the zeroes to determine the roots.
Write the polynomial as a product of the leading coefficient, a, and the factors, where each factor is x minus a root.
Use the y-intercept (0, –5) to solve for the leading coefficient.
Substitute the leading coefficient into the polynomial function for a and simplify.

Drag the tiles to the correct boxes to complete the pairs. Match the values based on parallelogram ABCD, shown in the figure. length of value of m∠DAB value of 56 arrowRight 4 arrowRight 44 arrowRight 2 arrowRight
Answer:
56 ---> m< DAB
4 ---> length of line BC
44 ---> value of y
2 ---> value of x
Step-by-step explanation: edmentum test answer
The length of BC is 4 units, the value of y is 44, a measure of the angle DAB is 56 degrees, and the value of x is 2.
What is parallelogram?In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have:
Parallelogram ABCD
From the figure:
6 - x = x + 2
2x = 4
x = 2
Length of BC = 6 - x = 6 - 2 = 4 units
12 + y = 100 - y
y = 44
Angle DAB = 100 - 44 = 56 degrees
The value of x = 2
Thus, the length of BC is 4 units, the value of y is 44, a measure of the angle DAB is 56 degrees, and the value of x is 2.

Answer:
1) Product of 2 x 3/5 is 6/5 or 1 and 1/5.
2) 20/9 or 2 and 2/9
3) 15/8 or 1 and 7/8
4) 15/6 or 2 and 3/6 or 2 and 1/2
5) 6/4 or 1 and 2/4 or 1 and 1/2
Step-by-step explanation:
You multiply the whole number by the numerator (top number) and then divide the result by the denominator(bottom number). Afterward, simplify the fraction if you can, for example, 6/9. Both the numerator and denominator can be divided by 3. Therefore, the answer to that example is 2/3.
Answer:
1) Product of 2 x 3/5 is 6/5 or 1 and 1/5.
2) 20/9 or 2 and 2/9
3) 15/8 or 1 and 7/8
4) 15/6 or 2 and 3/6 or 2 and 1/2

Three friends went to Staples for school supplies. Anna bought two notebooks, one pencil, and three
binders for $14.50. Josh bought one notebook, four pencils, and one binder for $7.50. Alex bought 3 notebooks,
two pencils and two binders for $14.50. Find the price of each item by solving a system of three equations
algebraically
Answer:
A pencil costs $0.50
A binder costs $3.00
A notebook costs $2.50
Step-by-step explanation:
Represent Notebook with N, Pencil with P and Binder with B
For Anna:.
2N + P + 3B = 14.50
For Josh:.
N + 4P + B = 7.50
For Alex:
3N + 2P + 2B = 14.50
Required
Solve for N, P and B
Make N the subject in the second equation
N + 4P + B = 7.50
N = 7.50 - 4P - B
Substitute 7.50 - 4P - B for N in the first equation
2N + P + 3B = 14.50
2(7.50 - 4P - B) + P + 3B = 14.50
Open Bracket
15.0 - 8P - 2B + P + 3B = 14.50
Collect like terms
3B - 2B + P - 8P = 14.50 - 15.0
B - 7P = -0.50
B = 7P - 0.50
Substitute 7.50 - 4P - B for N in the third equation
3N + 2P + 2B = 14.50
3(7.50 - 4P - B) + 2P + 2B = 14.50
22.50 - 12P - 3B + 2P + 2B = 14.50
Collect Like Terms
2P -12P + 2B - 3B = 14.50 - 22.50
-10P - B = -8
Multiply through by -1
10P + B = 8
Recall that B = 7P - 0.50
10P + B = 8 becomes
10P + 7P - 0.50 = 8
17P - 0.50 = 8
17P = 8 + 0.50
17P = 8.50
Divide through by 17
P = 8.50/17
P = 0.50
This implies that a pencil costs $0.50
Substitute 0.50 for P in B = 7P - 0.50
B = 7 * 0.50 - 0.50
B = 3.50 - 0.50
B = 3.00
This implies that a binder costs $3.00
Substitute 3.00 for B and 0.50 for P in N = 7.50 - 4P - B
N = 7.50 - 4 * 0.50 - 3.00
N = 7.50 - 2.00 - 3.00
B = 2.50
This implies that a notebook costs $2.50

In triangle ABC, the measure of angle B is 50 degrees. Give possible values for the measures of angles A and C if ABC is a right triangle.
9514 1404 393
Answer:
A = 90°, C = 40°A = 40°, C = 90°Step-by-step explanation:
In a right triangle one angle is 90° and the other angle is the complement of the acute angle given.
Angles A and C are not specified, but we know the other two angles are 40° and 90°. The values can be assigned two ways:
A = 90°, C = 40°
A = 40°, C = 90°
