Solve for x: 4(2x -1) + 8 -14x = -8x + 4 + 2x
Answers
Answer:
The value of x is all real numbers.
Step-by-step explanation:
4(2x -1) + 8 -14x = -8x + 4 + 2x <== distribute 4
4(2x) + 4(-1) + 8 -14x = -8x + 4 + 2x
8x - 4 + 8 -14x = -8x + 4 + 2x <== combine any like terms on both sides
-6x + 4 = -6x + 4 <== both sides are equal
Since both sides of the equation are equal, this means that any x value makes the equation true. Any real number can be used as the value of x.
Hope this helps!

What is an equation of the line that passes through the points (-8, 1) and (7, 1)
Answers
ANSWER: y = 1
STEPS:
first, find the slope by using the formula
which is also represented as m
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
where from point (-8, 1) x1 is -8 and y1 is 1
then from point (7, 1) x2 is 7 and y2 is 1
so we substitute into the formula
[tex] \frac{1 - 1}{7 - ( - 8)} = \frac{0}{7 + 8} = \frac{0}{15} [/tex]
[tex]m = \frac{0}{15} [/tex]
Then we solve for the equation of the line by using the formula
[tex](y - y1) = m(x - x1)[/tex]
but we have only y1, m and x1 so we substitute given us
[tex](y - 1) = \frac{0}{15} (x - ( - 8))[/tex]
but also, we must get rid of the fraction 0/15
so we multiply through by the denominator 15
[tex]15 \times (y - 1) = 15 \times \frac{0}{15} (x - (8))[/tex]
we get
[tex]15(y - 1) = 0(x - ( - 8))[/tex]
now we expand all brackets
[tex]15y - 15 = 0[/tex]
but we want the equation so we make y stand alone
[tex]15y = 15 \\ \\ \frac{15y}{15} = \frac{15}{15} \\ \\ y = 1[/tex]
the equation of the line is y=1

Suppose that a cylinder has a radius of r units, and that the height of the cylinder is also r units. The lateral area of the cylinder is 882 π square units. Find the value of r.
Answers
Answer:
21 units²
Step-by-step explanation:
the area of a circle is
pi×r²
the lateral area of a cylinder is the area only if the "mantle" of the cylinder : the round area all around the cylinder in its side.
in other words : everything but the ground and the top area.
how can we get the area of the side "mantle" ?
we can imagine, we take a knife and cut a straight line (and at 90°) from the top to the bottom, and then cut off the ground and the top circles by cutting along their circumference.
what do we get ?
if we put that remaining area in the table and press it flat, it is ... a rectangle. simply a rectangle.
its width is the height of the cylinder (the length of our initial top-bottom cut).
and its length is the length of the circle circumference that e just cut off.
and the circumference of a circle is
2×pi×r
so, the lateral area of the cylinder is
2×pi×r × h
r being the radius
h being the height of the cylinder.
and we get
LA = 2×pi×r×r = 882×pi
pi × r² = 441 × pi
r² = 441
r = 21 units²

The circumference of a circle is 106.76 millimeters. What is the circle's diameter?
Use 3.14 for .
Answers
Answer:
CIRCUMFERENCE (of a circel) = 3.14 * DIAMETER
C = 3.14 * D
106.76 mm = 3.14 * D
hence, D = (106.76 mm)/ 3.14
D = 34mm
Therefore the diameter of the circle is 34mm
