Answer:
32 - 4x = 12
Step-by-step explanation:
Substitute x = 5 into the equations and compare:
18 - 2x = 18 - (2 x 5) = 18 - 10 = 8 incorrect
32 - 4x = 32 - (4 x 5) = 32 - 20 = 12 correct
11 + 6x = 11 + (6 x 5) = 11 + 30 = 41 incorrect
25x + 4 = (25 x 5) + 4 = 125 + 4 = 129 incorrect
[tex]x^5+5=(5^5)+5=25+5=30[/tex] incorrect
3x + 1 = (3 x 5) + 1 = 15 + 1 = 16 incorrect
solve system of equations:
4x + 3y = 10
3x + y = 15
Answer:
x= 7 y= -6

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

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.

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
2. Given g(x) =1/2x+5, find the following.
a. g(4)
b. g(-10)
C. g(0)
Can someone please help me?
Answer:
Look below
Step-by-step explanation:
To do this, we have to substitute each number for x...
a. [tex]g(4)=\frac{1}{2}(4)+5=\frac{4}{2}+5=2+5=7[/tex]
b. [tex]g(-10)=\frac{1}{2}(-10)+5=\frac{-10}{2}+5=-5+5=0[/tex]

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

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.

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:
