The graph of linear function g passes through the points (3, 7) and (9, 3).
Which statement must be true?
A. The graph of g passes through the point (6,-2)
B. The zero of g is -6
C. The slope of the graph is -2/3
D. The x-intercept of the graph of g is 6
Answer:
c
Step-by-step explanation:
The slope of the graph is -2/3 is true.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁.
The graph of linear function g passes through the points (3, 7) and (9, 3).
We need to find which statement is true from options.
Slope=3-7/9-3
=-4/6
=-2/3
The slope intercept form 7=-2/3(3)+b
7=-6/3+b
7=-2+b
b=9
Hence, the slope of the graph is -2/3 is true.

How do I find x and what’s the relation ?
Answer:
X=17
Step-by-step explanation:
Im sorry if this sounds a bit confusing. Im better at doing the math then explaining it. All the angles in that are 90-degree angles and because of that, you can assume that the angle that you trying to find is also 90 degrees. So to find that equation you can do this.
4x+22=90 -22 from both sides.
-22=-22
you are left with
4x=68 then divide 4 from both sides.
/4=/4
you then get x=17 which is your answer.
Check your answer by plugging 17 into x.
4*17+22=90
The answer is 90 so you are correct.

What is the solution to the equation –5w + 3 = 4w – 6?
Answer:
-2=2
Step-by-step explanation:
Answer:
w = 3
Step-by-step explanation:
-5w + 3 = 4w - 6
were going to get the variable and the numbers on different sides
-5w + 3 - 3 = -5w
4w - 6 - 4w = -6
-5w + 4w = -1w or -w
-6 + 3 = -3
-w = -3
and since there're both negatives you can just take that away and you get
w = 3
In 1968 it cost $54 000 for a 30-second commercial during the super bowl. In 1973, the cost for a 30-second commercial was $88,000. What is the percent increase, rounded to the nearest whole number, in the cost for a 30-second commercial from 1968 to 1973?
Answer:
63 %
Step-by-step explanation:
Percentage change in value value for any number is given by
percentage change = (new value - old value) /old value * 100
we can also write it as
percentage change = (change in value ) /old value * 100
________________________________________
cost of commercial in 1968 = $54000
cost of commercial in 1973 = $88000
change in cost of commercial = cost of commercial in 1973 - cost of commercial in 1973 = $(88000-54000) = $34000
thus,
percentage change in cost of commercial
= change in cost of commercial/cost of commercial in 1968 * 100
= 34000/54000*100 = 62.96 %
Thus, percentage change in cost of commercial is 62.96 %
we have to round it to nearest whole number
rounded value of 62.96 is 63
in that case
percentage change in cost of commercial is 63 %

-3x + 2c = -3, solve for x
Answer:
x=2c/3+1
Step-by-step explanation:
Subtract 2c from both sides.
−3x=−3−2c
The equation is in standard form.
−3x=−2c−3
Divide both sides by −3.
-3x/-3=-2c-3/-3
Dividing by −3 undoes the multiplication by −3.
x=-2c-3/-3
Divide −3−2c by −3.
x=2c/3+1

Solve each equation.
7(1 +4n) - 5=-38 + 8n
Answer:
B) n=-2
Step-by-step explanation:
First, distribute.
7(1+4n)-5=-38+8n
7+28n-5=-38+8n
Combine like terms.
2+28n=-38+8n
To make solving the equation easier, subtract 8n first, so there isn't a negative variable.
2+28n=-38+8n
-8n -8n
2+20n=-38
Subtract 2 on both sides.
2+20n=-38
-2 -2
20n=-40
Divide by 20 on both sides.
20n=-40
/20 /20
n=-2

find the midpoint of the segment with the following endpoints. (6, 3) and (0, 9)
Answer:
(3,6)
Step-by-step explanation:
In order to find midpoint you need to add x1 + x2 then divide by 2. Then the same for y. y1 + y2 then divide by two.
In this case we have 6 + 0 = 6 then divide by 2 which is 3.
Then we have 3 + 9 = 12 then divide by 2 which is 6.

150+25x=55x what is the answer?
Answer:
x = 5
Step-by-step explanation:
150+25x= 55x
-25x -25x
150= 30x
150/30 = 30x/30
x = 5
Hope this helps!
Answer: x =5
Steps: 150 + 25x = 55x
Subtract 150 from both sides: 150 + 25x - 150 = 55x - 150
Simplify: 25x = 55x - 150
Subtract 55x from both sides: 25x - 55x = 55x - 150 - 55x
Simplify: -30x = -150
Divide both sides by -30: -30x ÷ -30 = -150 ÷ -30
Simplify: x = 5

Do rozwiązania są następujące zadania tekstowe:
Luca ma kilka 10-centówek oraz kilka 5-centówek. Razem ma 40 monet, o wartości
3.15 Euro. Ile monet każdego rodzaju ma Luca?
d = liczba monet 10-centowych
p = liczba monet 5-centowych
Razem, Luca ma 40 monet:
d + p = 40
Jedna 10-centowa moneta ma wartość 10 centów, i jedna 5-centowa ma wartość 5 centów, więc
10d + 5p = 315
bo 3,15 euro = 315 centów.
Znajdź d i p :
(10d + 5p) - 5(d + p) = 315 - 5•40
5d = 115
d = 23
d + p = 40
23 + p = 40
p = 17
A grocer reports that the store has sold 72 of the 90 boxes of apples delivered this week. What percentage of the delivered apples have been sold?
Answer:
80%
Step-by-step explanation:
Total boxes of apples delivered = 90
Total boxes sold = 72
What percentage of the delivered apples have been sold?
Percentage sold = Total boxes sold / total boxes delivered × 100
= 72 / 90 × 100
= 0.8 × 100
= 80%
The percentage of the delivered apples have been sold is 80%
Percentage unsold = (total boxes delivered - total boxes sold) / total boxes delivered × 100
= (90 - 72) / 90 × 100
= 18 / 90 × 100
= 0.2 × 100
= 20%
The percentage of the delivered apples have been sold is 80% and this can be determined by using the unitary method.
Given :
A grocer reports that the store has sold 72 of the 90 boxes of apples delivered this week.
The following steps can be used in order to determine the percentage of the delivered apples that have been sold:
Step 1 - The unitary method can be used in order to determine the percentage of the delivered apples that have been sold.
Step 2 - According to the given data, 90 boxes are 100% boxes of apples.
Step 3 - Now, let the percentage of the delivered apples that have been sold be 'x'. So, the value of 'x' is:
[tex]x = \dfrac{72}{90}\times 100[/tex]
Step 4 - Simplify the above expression.
[tex]x = 80\%[/tex]
Therefore, the percentage of the delivered apples have been sold is 80%.
