To solve the equation 8x - 19 = -4 - 7x, you must:
Rearrange the terms: 8x − 19 = −4 − 7x TO 8x − 19= − 7x −4Add 19 to both sides: 8x - 19 = - 7x = 4 TO 8x - 19 + 19 = - 7x -4 + 19Simplify by adding the numbers: 8x = - 7x + 15Add 7x to both sides: 8x + 7x = - 7x + 15 + 7xSimplify by combining like terms: 15x = 15Divide by like terms: 15x / 15 = 15 / 15 = 1x = 1Simplify: x = 1PLS HELP!!!!!what is the equation

Which table represents a linear function?
Answer: table 1.
Step-by-step explanation: This is because the x-axis is going up by 2 and the y-axis is also going up by 2. There is a pattern and when you would graph it, it will be linear as it goes up by the same amount
Jorge Claims that the distance between his house and the library is 13 miles. His city is placed on a coordinate plane. Jorge's House is at the coordinates (5, 1), the mall is at coordinates (2, 11) and hte Library is at cordinates (10, 13). What equation verifies his claim?
Answer:
House coordinate = (5, 1)
Library coordinate = (10, 13)
Step-by-step explanation:
Given :
House coordinate = (5, 1)
Library coordinate = (10, 13)
Distance between house snd library :
Distance = sqrt[(x2 - x1)² + (y2 - y1)]
x1 = 5, x2 = 10, y1 = 1, y2 = 13
Distance = sqrt[(10 - 5)² + (13 - 1)²]
Distance = sqrt[(5² + 12²)]
Distance = sqrt(25 +144)
Distance = sqrt(169)
Distance = 13

Colin buys a car for £28100.
It depreciates at a rate of 4% per year.
How much will it be worth in 6 years?
Give your answer to the nearest penny where appropriate.
Answer:
The amount the car will be worth after 6 years is £21,917 and 22 pence
Step-by-step explanation:
The amount for which Colin buys the car, PV = £28,100
The amount by which the car depreciates each year, r = 4%
The number of years after which the value of the car is sought, n = 6 years
The future value, FV, based on an annual depreciation is given as follows;
[tex]FV = PV \times \left ( 1 + \dfrac{r}{100} \right ) ^n[/tex]
Substituting the known values gives;
[tex]FV_6 = 28,000 \times \left ( 1 - \dfrac{4}{100} \right ) ^6 = 21,917.22[/tex]
Therefore, the amount the car will be worth after 6 years, future value FV₆ = £21,917 and 22 pence

An invertible function is represented by the values in the table.
Which graph shows the inverse of this function?
Answer:
Graph B
Step-by-step explanation:
Because th inverse fuction is f^-1(x), you basicaly swap the numbers, all x valuese would equal y.
In this exercise we have to identify the treated inverse function and the graph that corresponds to it, so we have that what corresponds to this is:
Graph B corresponds to the given function.
In this way, the inverse function corresponding to:
[tex]f^{-1}(x)[/tex]
Because th inverse fuction is f^-1(x), you basicaly swap the numbers, all x valuese would equal y. So we will have that the graph that correctly corresponds to this function is graph B.

A wooden box has a square base. The height of this box is 3 times the length of one side of the base. If one side of the base is 3 feet long, what is the volume of this box?
Answer:
[tex]V=81\ \text{feet}^3[/tex]
Step-by-step explanation:
A wooden box has a square base
One side of the base is 3 feet
The height of this box is 3 times the length of one side of the base, h = 3(3) = 9 feet.
The volume of the box is given by :
[tex]V=A\times h[/tex]
A is area of base
For square base, A = side²
[tex]V=3^2\times 9\\\\=81\ \text{feet}^3[/tex]
So, the volume of this box is [tex]81\ \text{feet}^3[/tex]
Can someone help me with this trigonometry question
==================================================
Explanation:
Apply the law of cosines to find angle C
c^2 = a^2 + b^2 - 2*a*b*cos(C)
19^2 = 11^2 + 17^2 - 2*11*17*cos(C)
361 = 121 + 289 - 374*cos(C)
361 = 410 - 374*cos(C)
361 - 410 = -374*cos(C)
-49 = -374*cos(C)
-374*cos(C) = -49
cos(C) = (-49)/(-374)
cos(C) = 0.131016042780749 ..... which is approximate
C = arccos(0.131016042780749)
C = 82.4716905247836
C = 82 degrees
Notes:
arccos is shorthand for "arccosine". It is the same as inverse sine.Make sure your calculator is in degree mode. You can check by computing cos(60) and you should get 0.5LeeAnn earns an annual salary of $50,000 after taxes. Her average expenses per month come to $3,350. If she saves all the money that she doesn't use to pay expenses, how much will she have in savings at the end of the year?
Answer:
$9800
Step-by-step explanation:
Given that:
Annual salary = $50,000
Average monthly expenses = $3350
Average amount spent per annum:
Number of months in a year = 12
12 * $3350 = $40,200
Since, all amount not used as expenses is saved :
Total amount saved = $50,000 - $40,200
Total amount saved = $9800

HEEEEEELP IF U CAN EXPLAIN PLEASO DO IT TANK U
Answer:
130 degrees
Step-by-step explanation
Angle 6 is 130 degrees because it has a vertical angle relationship with the angle measure of 130 degree
Angle 6 and 2 are equal because of the corresponding angle relationship
OR
The angle measure of 130 degrees have an alternate interior angle relationship with angle 2 which makes them equal
Therefore angle 2 is 130

A cherry pie has a 16 inch diameter. What is its approximate area? Round to the nearest hundredth. (Use 3.14 for π)
Answer:
200
Step-by-step explanation:
Formula to find the area: πr²
First, find the radius: 16 ÷ 2 = 8
The radius is 8. So...
= 3.14 (8²)
= 3.14 × 64
= 200.96
Rounded to the nearest hundredth: 200
Answer:
200.96
Step-by-step explanation:
A=3.14r^2(formula for area of a circle)
r=16/2=8
r=8
A=3.14*8^2=200.96
Find the coordinates of the point where y-4x=1 crosses the y axis
Answer:
The coordinate is (0,1) .
Step-by-step explanation:
A linear equation is given to us and we need to find the point at which it will cut y axis . The given eqution is y - 4x = 1. We know that at y axis x coordinate is 0. So on substituting x = 0 , we have ;
Put x = 0 :-
⇒ y - 4x = 1
⇒ y - 4*0 = 1
⇒ y - 0 = 1 .
⇒ y = 1 .

What is 27.9789767993 round to nearest tenth
Answer:
28.0
Step-by-step explanation:
if rounding to the nearest tenth then the number in the hundredth determines what to do - if the number in hundredths is '5 and above, give it a shove'
meaning in this case the 7 bumps the 9 up by one; but a nine will carry over and bump the number in the ones place up by one
Answer:
28
Step-by-step explanation:
Hi there!
This decimal is a tricky one.
we know we’re rounding to the nearest tenth, so the hundredths place will come in handy.
Since there is a 7 in the hundredths place, we know we’re going to round up, but we have a 9 in the tenths place, so it would become a ‘10’, which is just going into the next whole number, which is 28.
I hope this helped!
