Answer:
x = -6Step-by-step explanation:
7x+8=4x-10
3x = -18
x = -6
-------------------
check
7 * (-6) + 8 = 4 * (-6) - 10
-34 = -34
the answer is good
solve the linear system using elimination

A camera has a listed price of $801.99 before tax. If the sales tax rate is 8.5%, find the total cost of the camera with sales tax included.
Round your answer to the nearest cent, as necessary.
Answer:
$870.16 dollars
Step-by-step explanation:
Given the following question:
Original cost = $801.99
Sales tax of 8.5%
In order to find the answer, we find 8.5% of the original cost of the camera. After that, we simply add that number to the original cost of the camera to find our answer.
[tex]\frac{8.5\times801.99}{100} =8.5\times801.99=6816.915\div100=68.16915[/tex]
[tex]68.16915[/tex]
[tex]9>5[/tex]
[tex]68.17[/tex]
Sales tax is $68.17
[tex]801.99+68.17=870.16[/tex]
Total price for the camera including tax is "$870.16."
Hope this helps.
A trolley charges $3.00 just to get in the car and $1.00 for each mile traveled. How much would it cost to travel 5 miles? 8 miles? 20 miles?
Answer:
5 miles = $8
8 miles = $11
20 miles = $23
Step-by-step explanation:
If admission is 3 dollars, then we already know that is the minimum we have to pay. The rest of the money we spend on the trolley depends on how many miles we travel on it. If each mile is 1 dollar, then we can use a variable to represent the number of miles since there are numerous possible answers.
The basic equation to represent the scenario is:
3 + x
Since x represents the amount of miles traveled, we can replace it with 5, 8, or 20.
3 + 5 = 8 dollars
3 + 8 = 11 dollars
3 + 20 = 23 dollars

Question 1 of 10
Which inequality represents all values of x for which the product below is
defined?
VX-6. Vx+3
O A. X2-3
O B.X26
O c. x20
O D. Xs6
Answer:
B. x ≥ 6
Step-by-step explanation:
The value √(x-6) is only defined for x ≥ 6, where the argument of the square root function is non-negative.
Similarly, the value √(x+3) is only defined for x ≥ -3.
The product can only be computed where both functions are defined:
(x ≥ 6) ∩ (x ≥ -3) = x ≥ 6
What is the point-slope form of a line with slope 4/5 that contains the point (-2, 1)?
A. y - 1 = 4/5(x + 2)
B. y + 1 = 4/5(x - 2)
C. y - 1 = 4/5(x - 2)
D. y + 1 = 4/5(x + 2)
Hi! Let me help you! :)
We are given the slope of the line and a point that it passes through.We can use the Point-Slope formula:y-y1=m(x-x1)y-1=4/5(x-(-2)y-1=4/5(x+2)Answer:
y-1=4/5(x+2)

If you know the circumference of a circle how do you find diameter?
Answer:
circumference of a circle = [tex]\pi[/tex]d
Step-by-step explanation:
circumference of a circle = 2[tex]\pi[/tex]r
where r = radius
diameter of a circle d = 2r
where r = radius
Therefore, circumference of a circle = [tex]\pi[/tex]d

By using the definition of collinear and coplanar points, we will see that
7) Collinear points: All lie on the same line.8) Coplanar points: All lie on the same plane.What do collinear and coplanar mean?We say that a given set of points is collinear if all the points belong to the same line, just to give an example, any pair of two points is collinear, as we always can find a line that passes through two points.
On other hand, a set of points is coplanar if the points lie on the same plane. Remember that a plane is defined by a line and a point outside of it.
With these definitions in mind, we can answer:
7) Collinear points: All lie on the same line.8) Coplanar points: All lie on the same plane.If you want to learn more about collinear and coplanar, you can read:

Step-by-step explanation:
Start with €467.
End up with €88.
Total amount withdrawn:
€467 - €88 = €379
The total amount was withdrawn in 5 equal amounts.
Each amount taken is:
€379 ÷ 5 = €75.80
In 1990, a donut shop sold 500 donuts per day. In 2000, they sold 700 donuts per day. Assuming a linear relationship, how many donuts did they sell per day in 2015?
Answer:
1,000
Step-by-step explanation:
In 1990, 500 donuts were sold per day. In the year 2000 the number of donuts sold went up by 200 to reach 700 donuts per day. Since we are to assume it's a linear relationship, it would mean that every ten years the number of donuts sold would go up by 200/day. In 2010 the shop would be selling 900 donuts per day. So, in 2015, The shop would be selling 1,000 donuts per day since only 5 years had passed since 2010 and after 5 years it would only go up by 100/day.
What is the equation of the line that passes through the point (3,−3) and has a slope of 0?
Answer:
x = 3
Step-by-step explanation:
A line with a slope of 0 is a horizontal line parallel to the x- axis with equation
x = c
where c is the value of the x- coordinates the line passes through.
the line passes through (3, - 3 ) with x- coordinate 3 , then
x = 3 ← equation of line
Answer:
f(x) = -3
Step-by-step explanation:
it will be a constant function because if the slope = 0, the y value is not changing
so the equation of the line, f(x) = ax+b, will be f(x) = 0x+b
f(x) = b, b is the y value here

Two quantities that form a proportion are?
what is the gradient of the blue line ??
Answer:-5
Step-by-step explanation:
The solution is in the attached file below
The gradient of the blue line that passes through the points (-1, 0) and (0, -5) is -5.
What is the slope ( gradient ) of the line?The Slope (gradient) is simply expressed as a change in y over the change in x.
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
The blue line in the graph runs through points (-1, 0) and (0, -5).
To find the gradient (slope) of the blue line passing through the points (-1, 0) and (0, -5), we use the slope formula.
Point (-1,0): x₁ = -1 and y₁ = 0
Point (0, -5): x₂ = 0 and y₂ = -5
Plug the coordinates into the above formula:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}\\\\m = \frac{-5 - 0}{0 - (-1)}\\\\Simplify:\\\\m = \frac{-5 - 0}{0 + 1}\\\\m = \frac{-5}{ 1}\\\\m = -5[/tex]
Therefore, the slope is -5.
