Answer:
A
Step-by-step explanation:
We are given the function g(x) = -2x +5
If we need an output of -5, then:
-5 = -2x + 5
-10 = -2x
x = 5
A
Answer:
a. 5
Step-by-step explanation:
We can solve this by simply guessing and checking; plugging in each answer until we get -5.
a) -2(5) + 5
-10 + 5
-5
We can also set the function equal to -5 and solve for x.
-2x + 5 = -5
-2x = -10
x = 5

Tell whether the ratios form a proportion
2: 8/3 and 2/3: 6
Answer:
no
Step-by-step explanation:
you can cross-multiply and see if you get the same products
(2/1 ÷ 8/3) / (2/3 ÷ 6/1)
2/1 · 6/1 ≠ 8/3 · 2/3
12 ≠ 16/9

Explicit function of a sequenceGiven the function that represents a given given graph a f(x) = -x + 5
For the first term of the sequence, x = 1. Substitute into the function;
f(1) = -1 + 5
f(1) = 4
This shows that the point (1.4) means the 1st term of the sequence is 4.
For the second term, x = 2
f(2) = -2 + 5
f(2) = 3
This shows that the point (2, 3) means the 2nd term of the sequence is 3.

2. In the figure, x is an exterior angle to the triangle below.
(a) Explain why x is equal to the sum of the measures of the two nonadjacent interior angles. You need to present the algebra that proves this theorem.
(b) What is m
Answer:
Answer:
a) Exterior Angle Theorem
b) x = 109°
Step-by-step explanation:
For a, you can thank the Exterior Angle Theorem. Since the angles of a triangle equal 180°, we can figure out what the third interior angle's measurement is, then subtract that from 180 to get the exterior angle's measure. Since the two angles labeled (64° and 45°) will make an obtuse angle, then the third interior is an acute angle. Add 64 and 45 to get the exterior angle's measurement of 109 degrees. That would mean the third interior angle's measurement would be 71 degrees. 64 + 45 + 71 = 180, so this is true.

You deposit $500 in a savings account that earns 2.5% interest compounded yearly. Find the balance in the account after 1 year. Be sure your answer has a dollar sign. For example: $150.80 *
Answer:
$512.5
Step-by-step explanation:
Given data
P= $500
R=2.5%
T= 1 year
The compound interest formula is
A=P(1+r)^t
substitute
A=500(1+0.025)^1
A=500(1.025)
A=500*1.025
A=$512.5
Hence the balance is $512.5

Solve inequality:
-105 < -7(5 - 2n)-15 < -(5 - 2n)-15 < - 5 + 2n-10 < 2n-5 < nn > - 5Highlight the points to the right from -5
Answer:
[tex]n>-5[/tex]
Step-by-step explanation:
−105<−7(5−2n)
Divide both sides by −7. Since −7 is negative, the inequality direction is changed.
[tex]\frac{-105}{-7}[/tex] > 5−2n
Divide −105 by −7 to get 15.
15>5−2n
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
5−2n<15
Subtract 5 from both sides.
−2n<15−5
Subtract 5 from 15 to get 10.
−2n<10
Divide both sides by −2. Since −2 is negative, the inequality direction is changed.
n>[tex]\frac{10}{-2}[/tex]
Divide 10 by −2 to get −5.

It’s my last question :(
Answer:
Perimeter = 28·√2 + 24 feet
Step-by-step explanation:
The dimensions of the initial sheet of plywood are;
The length of the sheet of plywood = 25 ft.
The width of the sheet of plywood = 14 ft.
The shape cut from each corner of the sheet of plywood = A right triangle
The leg length of each of the cut out right triangles = 7 ft.
The number of leg lengths of the right triangle cut from the length side of the initial sheet of plywood = 2
The length of the parallel sides of the remaining hexagonal piece of plywood = Initial length of the plywood - 2 × The leg length of the cut out right triangle
∴ The length of the parallel sides of the remaining hexagonal piece of plywood = 26 ft. - 2 × 7 ft. = 12 ft.
The other side length of the remaining hexagonal piece of plywood = The hypotenuse side of the cut out right triangle
The hypotenuse side of the cut out right triangle = √((7 ft.)² + (7 ft.)²) = 7·√2 ft.
∴ The other side length of the remaining hexagonal piece of plywood = 7·√2
The number of side lengths in the remaining hexagonal piece of plywood = 4
The perimeter of the remaining hexagonal piece of plywood = 2 × The length of the parallel sides + 4 × The other side lengths
∴ The perimeter of the remaining hexagonal piece of plywood = 2 × 12 ft. + 4 × 7·√2 = (28·√2 + 24) ft.
The perimeter of the remaining hexagonal piece of plywood = (28·√2 + 24) feet

HELP WITHIN A HOUR!
Show work, please!
Answer:
A) 24
B) 24
Step-by-step explanation:
A) equilateral triangle means that all sides are equal
so each side is = 24 because the perimeter = 72
72/3= 24
B) 1 side = 24 and they gave you that 10+7h = 24
so h = 2
so hight of triangle = 2
Area = 1/2(b)(h)
so 24(2)(0.5) = 24

#8: Ella's grandmother sewed her a change purse. When she gifted it to her, Ella counted 23 coins already in it. Ella noticed there were only dimes and quarters worth $4.70. How many dimes were in the change purse?*
9514 1404 393
Answer:
7 dimes16 quartersStep-by-step explanation:
We can let d represent the number of dimes. Then the number of quarters is 23-d, and the total value of the change is ...
0.10d + 0.25(23 -d) = 4.70
-0.15d + 5.75 = 4.70
1.05 = 0.15d . . . . . . . . add 0.15d -4.70 to both sides
7 = d . . . . . . . . . . . . . . divide by 0.15
There were 7 dimes in the change purse.
__
There were 23-7 = 16 quarters.
