-(y + 2) + 8 = 3
=> -(y + 2) = -5
=> y + 2 = 5
=> y = 3
Line m is represented by the equation 2x + 4y - 12. Which of the following equations represents a line perpendicular to line m and intercects line m at its y-intercept?
-2x + y = 3
- 2x + y = 12
4x - 2y = 3
4x - 2y = 12
Answer:
A) -2x + y = 3
Step-by-step explanation:
The equation of the line that is perpendicular to the given line and passes through its y-intercept is -2x + y = 3.
We are given that;
The equation= 2x + 4y - 12
Now,
The given line is 2x + 4y - 12 = 0.
To find the slope of a line perpendicular to this line, we need to find the slope of the given line first.
Rewrite the equation in slope-intercept form which is given by:
y = mx + b
where m is the slope and b is the y-intercept.
2x + 4y - 12 = 0
4y = -2x + 12
y = (-1/2)x + 3
Hence, the slope of the given line is -1/2.
The slope of a line perpendicular to this line is the negative reciprocal of this slope which is given by:
[tex]m(perpendicular)[/tex] = -1/m = -1/(-1/2) = 2
To find an equation of a line that passes through the y-intercept of the given line and has a slope of 2.
The y-intercept of the given line can be found by setting x = 0:
2(0) + 4y - 12 = 0
y = 3
Hence, the y-intercept of the given line is 3.
The equation of a line with a slope of 2 and passing through (0,3) can be found using point-slope form which is given by:
y - y1 = m(x - x1)
where (x1,y1) = (0,3) and m = 2.
Substituting these values we get:
y - 3 = 2(x - 0)
y - 3 = 2x
y = 2x + 3
Therefore, by the equation answer will be -2x + y = 3.

Kendall measured the temperature outside to be 68°F. She needs to convert the temperature to degrees celsius.
C=5/9(F-32)
[]68°F is 20°C
[]68°F is 5.7°C
Answer:
68°F is 20°C
Step-by-step explanation:
C = (5/9)(F - 32)
C = (5/9)(68 - 32)
C = (5/9)(36)
C = 5 * 4
C = 20

ax+v=3x-3c
--subtract v from each side--
ax+v-v=3x-3c-v

[tex]x\left(a-3\right)=-3c-v[/tex]

can someone tell me how to solve translations please?
Step-by-step explanation:
Hey there!
Here; The coordinates are ; H(-4,-2), G(-5,3), F(-2,1)
The translation P(x,y) = P'(X+7,y)
Use same formula.
H(-4,-2) -------> P'(3,-2)
G(-5,3)-----------> G'(2,3)
F(-2,1)------------> F'(5,1)
Therefore, the answer is Option C.

42What best describes the relationship between the following two lines?
y = 2x +4
y = –2x +
4
Parallel
Perpendicular
Neither parallel nor perpendicular
Answer:
Neither parallel nor perpendicular
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Define lines
y = 2x + 4
y = -2x + 4
Parallel lines have the same slope but different y-intercepts. If the 2 lines were parallel, their m value would be the same. If the original line's slope is 2, the parallel line's slope would also be 2. Therefore, they aren't parallel.
Perpendicular lines have the negative reciprocal of the original slope. If the 2 lines were perpendicular, one slope would be 2 and the other slope would be -1/2. Therefore, they aren't perpendicular.
Therefore, our answer is neither parallel nor perpendicular.
Answer:
Neither parallel nor perpendicular.
Step-by-step explanation:
y = 2x +4
y = -2x + 4
The 2 slopes are 2 and -2.
If they were equal the 2 lines would be parallel.
If they had the relationship slope1 * slope2 = -1 they would be perpendicular.
They are neither so its the last choice.

In this figure, a line through points x and y will ______.
A. Be perpendicular to AB but not bisect it
B. Be the perpendicular bisector of AB
C. Bisect AB but not perpendicular
D. Be unrelated to AB
Answer:
B
Step-by-step explanation:
From the figure, its clear that the compass drew arcs like below:
With A as centre, and more than half of the length of AB as radius, one arc is drawn.
With the same radius, with B as centre, another arc is drawn.
The points of intersections of the arcs are X and Y.
Clearly, this is the construction of a perpendicular bisector of the line segment AB.
Hence, if we draw a line segment through XY, it will be a perpendicular bisector of AB.

0.00105 in scientific notation
Answer:
1.05 × 10^-3
Step-by-step explanation:
The decimal number 0.00105 in scientific notation is [tex]1.05 \times 10^{-3}.[/tex]
Scientific notation is a way to represent numbers that are either very large or very small.
It consists of two parts: the coefficient and the exponent.
The coefficient is a decimal number between 1 and 10, and the exponent indicates the power of 10 by which the coefficient is multiplied.
In the case of 0.00105, we can express it in scientific notation as [tex]1.05 \times 10^{-3}.[/tex]
