The table shows the total amounts y (in thousands of dollars) of money a homeowner saves on electric bills x years after installing solar panels.
a. Write an equation that models the total amount of money saved as a function of the number of years after the solar panels were installed.
y = _______
b. Interpret the slope and y-intercept of the line of fit.
The slope of the line means that the homeowner saves 1.6 thousand dollars per year while the y intercept means that the cost of installing the solar panels is 12 thousand dollars.
A linear equation is given by:
y = mx + b
where y, x are variables, m is the rate of change, b is the initial value of y (y intercept).
Let y represent the total money in thousand dollar saved for x years.
Taking the points (0, -12) and (20, 20).
The equation is given as:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-(-12)=\frac{20-(-12)}{20-0} (x-0)\\\\y+12=1.6x \\\\y=1.6x-12[/tex]
The slope of the line means that the homeowner saves 1.6 thousand dollars per year while the y intercept means that the cost of installing the solar panels is 12 thousand dollars.

Q; write the sentence as an equation. 251 is equal to 130 added to q
Answer:
251 = 130 + q
This is d equation
Answer:
251 = q + 130
Step-by-step explanation:
251 is equal to 130 added to q,
→ 251 = q + 130
Let's solve the equation,
→ 251 = q + 130
→ q = 251 - 130
→ [ q = 121 ]
So, the answer is 121.

Mona needs to photocopy a 14.5 centimeters wide by 15 centimeters long picture. She wants to enlarge the picture so that its length will be 45 centimeters. How wide will the enlarged picture be? 46.6 cm 43.5 cm 135 cm 44.5 cm
Answer:
43.5 cm
Step-by-step explanation:
The original photocopy's length is 15 cm. If Mona enlarges the photo's length to be 45 cm, we would need to find how much 15 is multiplied by to get 45, so that we can multiply 14.5, the width, by the same amount.
45/15 = 3
14.5 * 3 = 43.5 cm
Answer:
43.5

========================================================
Explanation:
Angles A and B are supplementary which mean they combine to form a straight line. This further means the angles add to 180.
A+B = 180
(8x-27) + (4x+3) = 180
(8x+4x) + (-27+3) = 180
12x-24 = 180
12x = 180+24
12x = 204
x = 204/12
x = 17
Use this x value to find angles A and B
A = 8x-27 = 8*17-27 = 109B = 4x+3 = 4*17+3 = 71Note how A+B = 109+71 = 180 to help verify the answer.
Answer:
109
Step-by-step explanation:
supplementary angles equals 180 degrees
8x-27+4x+3=180
12x-24=180
12x=204
x=17
Then you put the 17 where the x is
8(17)-27=109

Answer:
n = 55
n+15 = 70
2n = 110
Step-by-step explanation:
these angles are called 'same-side interior angles' and are supplementary
so we can add them together and set them equal to 180
n+15 + 2n = 180
combine 'like terms' to get:
3n + 15 = 180
subtract 15 from each side to get:
3n = 165
divide each side by 3 to solve for 'n'
n = 165/3
n = 55
substitute 55 for 'n'
55+15 = 70
2(55) = 110
check: 70 + 110 = 180

Answer:
It is congruent doe to the angle side angle congruence thereom AKA ASA
Step-by-step explanation:
That means there are two angles and one side in between. A pair of triangles that follow this rule has an angle that is congruent to one angle. Then a side that has a tick mark after the angle must match another. Then the last angle has to match another angle ( and it can't be the same angle as before). Usually the first pair angles have 1 semicircle and the second pair has 2 semicircles.

A researcher is following the growth of a particular type of flower. She writes the given equation to show the height of the flower g(n), in inches, after n days.
g(n) = 10(1.02)n
What does the average rate of change of the function represent?
A.
the number of days flower grew
B.
the average height of the flower after 5 days
C.
the average growth of the flower from day 1 to day 5
D.
the average time it takes for the flower to grow from 1-5 inches
The expression given represents an exponential growth relation. The average rate of change is the average growth of the flower from day 1 to days 5
The rate of change of the flower can be deduced frommthe equation as :
1.02 - 1 = 0.02Hence, the growth rate of the flower per day = 0.02
The number of days, n = 5
Therefore, the average growth rate is the average growth of the flower within the number of days given.

If x = 5y - 1 and 3x + 5y = -43, what is the value of y?
Answer:
y is the value of 1
Step-by-step explanation:
no need for one
Answer:
y = - 2
Step-by-step explanation:
Substitute x = 5y - 1 into the other equation
3(5y - 1) + 5y = - 43 ← distribute parenthesis and simplify left side
15y - 3 + 5y = - 43
20y - 3 = - 43 ( add 3 to both sides )
20y = - 40 ( divide both sides by 20 )
y = - 2
the ratio of calamansi and pomelo trees in jacintos farm is 8:5. how many trees of each kind are there if there are 793 trees in his farm?
The number of trees calamansi have is 488 trees. The number of tree pomelo trees have in Jacintos farm is 305 trees
From the given information, we learnt that:
The ratio of the calamansi and pomelo trees in Jacintos farm = 8:5
If the total number of the ratio = 8 + 5 = 13
The proportion of the calamansi can be estimated as:
= (8/13) × 793
= 488 trees
The proportion of pomelo trees is:
= (5/13) × 793
= 305 trees
Therefore, we can conclude that the number of trees calamansi have is 488 trees and the number of tree pomelo trees have in Jacintos farm is 305 trees.
