Step 1: Define
f(x) = -2x + 3
g(x) = 2x + 3
f(3) is x = 3 for function f(x)
g(7) is x = 7 for function g(x)
Step 2: Solve
Substitute in x [Functions]: f(3) = -2(3) + 3, g(7) = 2(7) + 3Substitute in functions: f(3) + g(7) = -2(3) + 3 + 2(7) + 3Multiply: f(3) + g(7) = -6 + 3 + 14 + 3Add: f(3) + g(7) = -3 + 14 + 3Add: f(3) + g(7) = 14i don't under stand this pls help

Answer: 2 and
Step-by-step explanation: equation 2:
3(3x+4)-5=9x-2
9x+12-5=9x-2
9x+7=9x+-2
Subtract both sides by 9x
7=-2
This Is not true therefore there is no solution
equation 3:
3(3x+4)-5=-3x+4
9x+12-5=-3x+4
9x+7=-3x+4
12x=-3
divide both parts by -3
x=-4
A theater sold 85% of the tickets for a
play. If 170 tickets were sold, how many
tickets were originally put up for sale?
Answer:
200 tickets.
Step-by-step explanation:
85% = 85/100 = 0.85
170/0.85 = 200
= 200
Check:
200*0.85 = 170
Answer: hope this helps ♡
200 tickets were originally put up for sale.
Step-by-step explanation:
85% = 170
(we divide 85 and 170 by 85)
1% = 2
(now multiply 1 and 2 by 100)
100% = 200
(double check: 85% from 200 → (85×200) ÷ 100 = 170 ✓)

A survey revealed that 20% of workers at a company were satisfied with their job. If 30 workers selected this option. How many total workers are at the company? Use the model below to help you solve the question.
Answer:
150 workers are at the company
Step-by-step explanation:
If 20% of the workers is equal to 30 workers than in order to find 100% of the worker you need to multiply the percentage with a number that makes it 100% and then multiply that number to the 30 workers so
20% * 5 = 100%
30 * 5 = 150
so 100% of the workers is equal to 150 workers

what 0.1315 with a bar over all numbers
Answer:
Step-by-step explanation:
0.1315 with a bar over all numbers means that the pattern of digits under the bar repeats without end. So the number is 0.1315131513151315131513151315....... etc
There is a formula to kind of simply this but I do not think that is what you are asking for.
Answer:
[tex]\overline{0.1315}=\frac{1315}{9999}[/tex]
Step-by-step explanation:
The trick is that because there are 4 digits being repeated infinitely, then this is equivalent to 1315/9999 because of the four 9s.

Write the equation of the line. Giving Brainliest to the fastest and most explanatory answer!
The equation of line shown in figure is,
⇒ y = x - 4
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (4, 0) and (0, -4).
Now,
Since, The equation of line passes through the points (4, 0) and (0, -4).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (- 4 - 0) / (0 - 4)
m = - 4 / -4
m = 1
Thus, The equation of line with slope 1 is,
⇒ y - 0 = 1 (x - 4)
⇒ y = x - 4
Therefore, The equation of line is,
⇒ y = x - 4

Answer:
17/30
Step-by-step explanation:
2/5 + 1/6 = 17/30
Make them easier to add by making them have the same denominator.
2/5 = 12/30
1/6 = 5/30
12/30 + 5/30 = 17/30
Answer:
17/30
Step-by-step explanation:
First, we need to get the lowest common denominator, which is 30 (5 times 6 and 6 times 5) since we multiplied the denominators we have to multiply the numerators by the same numbers (6 and 5) now we get 12/30 + 5/30, which equals 17/30

A box 2 m by 4 m by 8 m is filled with cubes of volume 8 cm³. If these
cubes were lined up, how long a line would that be?
The total line length of cubes lined up would be approximately 1.6 x 10^7 cm.
To find the total line length of cubes lined up, we need to find the total number of cubes in the box and then multiply it by the side length of a cube.
We can find the total number of cubes in the box by dividing the volume of the box by the volume of a cube:
Volume of the box = 2 m * 4 m * 8 m = 64 m³
Volume of a cube = 8 cm³ = 8 x 10^-6 m³ (converting the cm³ to m³)
Number of cubes = 64 m³ / 8 x 10^-6 m³ = 8 x 10^6
Then we can multiply the total number of cubes with the side length of a cube to find the total line length of cubes lined up :
Therefore, Line Length = 8 x 10^6 * 8 cm
= 6.4 x 10^7 cm
= 1.6 x 10^7 cm.
