Line m is a perpendicular bisector of line segment S Q. It intersects line segment S Q at point R. Line m also contains points T and V. Line segment S V is 4 x minus 1. Line segment S T is 3 x + 2.
Segment TQ is 26 units long. What is the length of QV?
8 units
26 units
31 units
32 units
Answer:
31 units
Step-by-step explanation:
just did on edge 2020
The length of QV is, 31 units
Hence, Option c is true.
We have to given that,
Line m is a perpendicular bisector of line segment SQ. It intersects line segment SQ at point R. Line m also contains points T and V.
Line segment SV is 4 x minus 1.
Line segment S T is 3 x + 2.
Since, Line m is a perpendicular bisector of line segment SQ. It intersects line segment SQ at point R. Line m also contains points T and V.
Hence,
TS = TQ
SV = VQ
Substitute all the values, we get;
TS = TQ
(3x + 2) = 26
3x = 26 - 2
3x = 24
x = 8
Hence, Lenght of SV is,
SV = (4x - 1)
SV = 4 × 8 - 1 = 32 - 1 = 31
Therefore, the length of QV is, 31 units

Write a slope intercept form for a line that passes through the points (-1,-1) and (2,5).
Answer:
y=2x+1
Step-by-step explanation:
First, find the slope by doing the slope formula.
[tex]\frac{y2-y1}{x2-x1} =\frac{5-(-1)}{2-(-1)} =\frac{5+1}{2+1} =\frac{6}{3}=2\\[/tex]
Then plug it into y-y1=m(x-x1)
y-5=2(x-2)

Since ED and DB are exactly half of EB, we can set ED and DB equal to each other.
x + 4 = 3x - 8
Subtract x from both sides. Add 8 to both sides
12 = 2x
Divide both sides by 2
6 = x
ED = 6 + 4 = 10
ED = DB = 10
EB = ED +DB = 10 + 10 = 20
ED = 10
DB = 10
EB = 20

Use the quadratic formula to find the solutions to the
quadratic equation below.
2x2 - 5x + 5 = 0
Answer: The answer is D.
The solution for the expression will be [tex]X = \dfrac{5\pm\sqrt{15}i}{4}[/tex]. The correct option is D.
What is a quadratic equation?A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given that the quadratic equation is 2x² - 5x + 5 = 0. The equation can be solved as below,
[tex]X = \dfrac{-b\pm\sqrt{b^2-4ac}}{4a}[/tex]
Substitute the values in the equation above,
[tex]X = \dfrac{-b\pm\sqrt{b^2-4ac}}{4a}[/tex]
[tex]X = \dfrac{-(-5)\pm\sqrt{(-5)^2-4\times2 \times4}}{4\times4}[/tex]

Create a table whose y-values are the square of the x-values.
Answer:
To create this table, first, you must find the values of x that you want to use, in this case, i will use the set:
{1, 2, 3, 4, 5, 6}
Now, first make a table as:
[tex]\left[\begin{array}{ccc}x&y\\1&\\2&\\3&\\4&\\5&\\6&\end{array}\right][/tex]
Now we need to complete the values of y.
we know that y(x) = x^2
then when we have x = 1, y(1) = 1^2 = 1.
when x = 2, y(2) = 2^2 = 4.
and so on, you input the values of x in the function y = f(x) = x^2
and the values of y are recorded in the table.
f(1) = 1^2 = 1
f(2) = 2^2 = 4
f(3) = 3^2 = 9
f(4) = 4^2 = 16
f(5) = 5^2 = 25
f(6) = 6^= 36
Then the completed table is:
What number makes the equation \large 4x-10=-42 true?
Answer:
-13=x
Step-by-step explanation:
4(-13)-10=-42
-52-10=-42
Answer:Simplifying
4x + -10 = 42
Reorder the terms:
-10 + 4x = 42
Solving
-10 + 4x = 42
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '10' to each side of the equation.
-10 + 10 + 4x = 42 + 10
Combine like terms: -10 + 10 = 0
0 + 4x = 42 + 10
4x = 42 + 10
Combine like terms: 42 + 10 = 52
4x = 52
Divide each side by '4'.
x = 13
Simplifying
x = 13
