Answer:
f(12) = 1680
Step-by-step explanation:
Substitute n = 12 into f(n) , that is
f(12) = 250 + 130(12 - 1) = 250 + 130(11) = 250 + 1430 = 1680
Solve x please!!!!!!!
Answer:
X=7
Step-by-step explanation:
These are supplementary angles. So they measure to 180º. 180º-95º=85º. 85º-10= 84º. 84º÷12x= 7.
Answer:
12x+1°+95°=180° (int angles)
12x+96°=180°
12x=180°-96°
=84°
x=84÷12
=7

Explain how to add integers that have like signs (all + or all -).
Answer:
Step-by-step explanation:
If there is two - signs you make it a positive
Answer:
Step-by-step explanation:
To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

what is an equation of the line in the slope- intersepct is (0,3)
Answer:
using the formula x/a + y/b =1
a: slope intercept on the x axis
b:slope intersect on the y axis
x/0 + y/3 = 1 (since x/0 is undefined ,the slope doesn't exist and it is impossible for a slope to be linear)

Write an equation of a line that passes through the point T ( − 2, − 5 ) and is parallel to the line y = 5 x + 7 .
Answer:
y = 5x + 5
Step-by-step explanation:
the slope to be parallel y = 5x + 7 must still be 5. To make the line pass through T, the given point, you plug (-2, -5) into the y= mx + b formula. This becomes( -5 )= 5 (-2) + B, and you solve for b. In this equation, b = 5.
write the equation of the line that is parallel to y=2x+1
Answer:
y = 2x, y = 2x+2, y=2x+100, y=2x-57, etc.
Step-by-step explanation:
Any line with the same slope will be parallel.

What is the equation of a line through point (-12,20) that is perpendicular to the line
with equation y=-6x + 4?
Find the slope of the perpendicular line
When two lines are perpendicular, the product of their slopes is -1. This means that the slopes are negative-reciprocals of each other.
⇒ if the slope of one of the lines = - 6
then the slope of the perpendicular line (m) = ¹/₆
Determine the equation
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - 20 = ¹/₆ (x - (-12))
∴ y - 20 = ¹/₆ (x + 12)
We can also write the equation in the slope-intercept form (y=mx+c) like the equation in the question by making y the subject of the equation and expanding the bracket to simplify:
since y - 20 = ¹/₆ (x + 12)
y - 20 = ¹/₆x + 2
y = ¹/₆x + 22
∴ the slope-intercept equation of the perpendicular line is y = ¹/₆ x + 22.

A team of explorers on an expedition was interrupted by bad weather on 20% of the days. If the weather was bad for 45 days, what was the total number of days the team was on its mission?
Answer:
a total of 9 days
Step-by-step explanation:
20% of 45 is 9
answer
=9days
step by step explanation
20% is always over 100,so you are to do 20 over a hundred of 45 days....since 45 can't divide 100 do 20
[tex] \times [/tex]
45 divide by one hundred and the final answer will be 9
What is 5x-7=-10x+8
subtract 5 from both sides -
5x - 7 = -10x + 8
-5 -5
-7 = -15x + 8
subtract 8 from both sides -
-7 = -15x + 8
-8 -8
-15 = -15x
now divide both sides by -15 -
-15/-15 = -15x/-15
The answer: x = 1
(x alone also equals 1)

Part B: Estimate the area of the whole retaining wall. A= LxW
For part c you need a equation
Part C: What is the area of the whole retaining wall? Write an equation to show your work. Compare your answer to your estimate to see whether your answer is reasonable
Answer with Step-by-step explanation:
a) 2 3/4 ÷ 3 = 11/12 feet
11/12 + 11/12 = 1 5/6
Or, you could write an algebraic equation:
2 3/4 ÷ 3 = x. (3x = 2 3/4)
x = 11/12
The height of the brick proportion of the wall is 1 5/6
b)
You know that 8 x 2 is 16. Well, you already know that the whole total of fractions, multiplied together, would probably be less that 1 and less than 1/2.
So, your rounded answer should be 16. Or 16 1/2
c)
Area = 8 1/2 x 2 3/4.
Use Distributive Property to solve the area.
(8 x 2) + (3/4 x 1/2) = x
8 x 2 = 16
3/4 x 1/2 = 3/8
16 + 3/8 = 16 3/8
x = 16 3/8
I think my answer is reasonable because I estimated 16, and 1/2. 3/8 is close to 1/2. That's why my answer is reasonable.

How long the meeting last = End time - Starting time
= 10:25 - 9:30
= 9:85 - 9:30 [I converted 10:25 to make it easier to see the
subtraction. This is posibble because 1hr = 60mins]

In the diagram below, AB and CB each have a length of 5 centimeters. If m<A=6(x-3) and m<C=4(x+1), determine the value of each angle of the triangle.
Considering that angles A and C are equal, and the sum of the internal angles of a triangle is 180º, we have that:
The measure of angle A is of: 48º.
The measure of angle B is of: 84º.
The measure of angle C is of: 48º.
-----------------------------
Segments AC and CB have the same length, thus, angles A and C have the same measure, and then:[tex]6(x - 3) = 4(x + 1)[/tex]
[tex]6x - 18 = 4x + 4[/tex]
[tex]2x = 22[/tex]
[tex]x = \frac{22}{2}[/tex]
[tex]x = 11[/tex]
[tex]6(11 - 3) = 6(8) = 48[/tex]
The measure of angle A is of: 48º.
The measure of angle C is of: 48º.
The sum of the internal angles of a triangle is of 180º, and this is used to find the measure of angle B.
[tex]mA + mB + mC = 180[/tex]
[tex]2(48) + mB = 180[/tex]
[tex]mB = 84[/tex]
The measure of angle B is of: 84º.
