Answer:2.16
Step-by-step explanation:
Solve each function for the given value.
Equation Given Value
Solution
a.) y = 15x - 50
when x = 7
b.) y = 1/2x + 20
when x = 50
c.) y = (3x)2 - 36
when x = 3
d.) y = 2.5x + 3.8
when x = 0.66
Answer:
a) y = 55
b) y = 45
c) y = -18
d) y = 5.45
Step-by-step explanation:
y = 15x - 50 when x = 7
y = 15(7) - 50
y = 105 - 50
y = 55
y = 1/2x + 20 when x = 50
y = 1/2(50) + 20
y = 25 + 20
y = 45
y = (3x)2 - 36 when x = 3
y = (3(3))(2) - 36
y = 9(2) - 36
y = 18 - 36
y = -18
y = 2.5x + 3.8 when x = 0.66
y = 2.5(0.66) + 3.8
y = 1.65 + 3.8
y = 5.45

I don't really understand this question.
Answer:
a) 3/2 or 1 1/2
b) 5/3 or 1 2/3
Step-by-step explanation:
1/2 + 1/2 + 1/2 =
3 x 1/2 =
3/2 or 1 1/2
1/3 + 1/3 + 1/3 + 1/3 + 1/3 =
5 x 1/3 =
5/3 or 1 2/3
Answer: (a) 1 1/2 and (b) 1 2/3
Step-by-step explanation: (a) 1/2 + 1/2 + 1/2 = 1/2 x 3
= 3/2
Now convert this into mixed fractions (basically divide the smaller number of the improper fraction by the the bigger one).
Therefore, 3/2 = 1 1/2 ( 1 1/2 is 1 whole and 1/2)
(b) 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 = 1/3 x 5
= 5/3
mixed number = 1 2/3 ( 1 2/3 is 1 whole and 2/3)
From midnight to 2:00 am, the temperature rose

The break-even point occurs when the amount of money they receive from selling popcorn is
equal to the amount of money they spent to make the popcorn. It is when Revenue-Total Cost.
The break-even point tells how many items they must create and sell in order to recover their
expenses.
4. Take the Total Cost and Revenue functions that you developed above, and sketch the graph
of the two functions on one coordinate plane. Label the axes appropriately.
7. Solve the equation R(x)-C(x) for x
5. Estimate the break-even point graphically.
6. To find the break-even point algebraically, write R(x)-C(x).

The poster is formed by a triangle and a rectangle, with their formula for the area being [tex]\frac{1}{2}[/tex] x base x height and base x height respectively.
Therefore, the area is [tex]\frac{1}{2}[/tex] x 27cm x 12cm + 20cm x 15cm, answer being 462cm2 (b) .
rite an addition equation to show how you decomposed
7/6
.
Answer:
For the fraction model, fill the whole left bar, and only 1 in the right bar.
The addition equation is:
⅙ + ⅙ + ⅙ + ⅙ + ⅙ + ⅙ + ⅙ = 7/6
Explanation:
Since the bar is divided into sixths (1/6 each), just count by 1/6 each time you fill each one and use the equation to represent the process.

Connie draws this model to help her solve a problem which expression is represented by Connie's model
∠1 and ∠2 are supplementary.
m∠1=124°
m∠2=(2x+4)°
What is the value of x?
Options:
13
26
40
36
41
Answer:26
Step-by-step explanation:Since angles 1 and 2 are supplementary, it follows that there sum is 180°.
On this note;
Sum of 1 and 2 is;
180 = 124 + (2x + 4)°
(2x + 4)° = 180 -124
2x = 56 -4
2x = 52
x = 26°.

The felt costs 9¢ per square inch. She will only pay for the felt used to cover the box, even if there is waste or extra. How much money did Hazel spend on the felt? (1 point)
a
$18.18
b
$27.72
c
$36.36
d
$45.54
Answer:
C. $36.36
Step-by-step explanation:
You need to find the surface area of the box. Then, calculate how much it will cost.
SA = 2(wl + hl + hw)
SA = 2([11*8] + [6*8] + [6*11])
SA = 2(88 + 48 + 66)
SA = 2(202)
SA = 404 inches
9 cents per inch
0.09*404 = 36.36

The triangle shown on the coordinate grid is translated 6 units to the right and 3 units down.
Which would be the measure of an angle of the resulting triangle?
(ignore the answer i choose lol) but pls help me
Answer:
75°
Step-by-step explanation:
Even if a triangle is translated, the original shape stays the same.
So, to get the answer, first add the first two angles of the triangle:
60 + 45 = 105
Then, subtract from 180, because 180 is equaled to all the angles added up on any triangle:
180 - 105 = 75.
So, you get 75°.
