Step-by-step explanation:
For 12 if its a parrell line then the slope of the two lines have to be the same. Since the slope is 3/5 then the answer is A because the slope in A is also 3/5
for 13 if its perpendicular, then the slope has to be the opposite sign and flipped. so for example if its a negative then the slope has to be a positive and if the slope is 1/2 you have to flip it which is 2/1 and 2/1 equals 2.
so in this one if the slope is 3/5 we have to flip it making it 5/3 and the opposite of a positive is a negative so it would be -5/3, so the answer is C.
Answer:
12. A
13. C
Step-by-step explanation:
12. to be parallel needs same slope
13. to be perpendicular flip slope and if positive change to negative

Step-by-step explanation: The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.
The elevator of a building is currently 10 feet above ground level on the first floor. The building's elevator rises at a rate of 5 feet per second. You enter the elevator on the first floor. Let t, represent the number of seconds you are in the elevator and h(t) represent the height of the elevator (in feet). Write an equation for h(t) b. What will your height be in 12 seconds? c. What does h(5) = 35 represent?
Answers
Answer:
[tex]h(t) = 10 + 5t[/tex]
70 feet
Your height in 5 seconds is 35 feet
Step-by-step explanation:
From the question, we understand that:
[tex]Initial\ Height = 10[/tex]
[tex]Rate = 5[/tex] per second
Solving (a): Equation for h(t)
This implies that the height at t seconds and is calculated as thus:
[tex]h(t) = Initial\ Height + Rate * t[/tex]
Where t represents seconds
Substitute values for Initial Height and Rate
[tex]h(t) = 10 + 5* t[/tex]
[tex]h(t) = 10 + 5t[/tex]
Solving (b): Height in 12 seconds
This implies that:
[tex]t = 12[/tex]
Substitute 12 for t in [tex]h(t) = 10 + 5t[/tex]
[tex]h(12) = 10 + 5 * 12[/tex]
[tex]h(12) = 10 + 60[/tex]
[tex]h(12) = 70[/tex]
Hence, your height will be 70 feet
Solving (c): h(5) = 35 means?
Using the illustration in (b) above;
This means that your height in 5 seconds is 35 feet
which one is 25%? please help me
Answers
So first of all you count all the blocks, so it will be 16 blocks (4x4) sideways and horizontal.
A = 16/4 marked blocks = 25%
B = 16/8 marked blocks = 50%
C = 16/6 marked blocks = ?
D = 16/10 marked blocks = 62,5%
So answer would be A
The length of a room is 2 1/2 feet more than its width. If the perimeter of the room is 80 feet, find its width and length?
Answers
Answer:
The width is 20.625 and the length is 19.375
Step-by-step explanation:
Let 2 1/2 + w = length
Let w = width
Equation:
2 1/2 + w + w = 80 Combine liked terms
2 1/2 + 2w = 80
-2 1/2 -2 1/2 Subtract 2 1/2 from both sides
2w = 77.5
÷ 2 ÷ 2 Divide 2 from both sides
w = 41.25
Length:
2 1/2 + 41.25 = 165/4 or 38.75
Width:
41.25
41.25/2 = 20.625
38.75/2 = 19.375
Write an equation in slope-intercept form of a line that passes through the point (8,-0) and is perpendicular to the line x - 3y = 15.
y = 3x −24y = 3x −24
y = 3x + 24
y = -3x + 24
y = -3x - 24
Answers
Step-by-step explanation:
let eqn be y = mx + b.
3y = x - 15
y = 1/3x - 5
perpendicular means product of grad = -1
hence m = -3.
sun (8, 0):
8 = -3(0) + b
b = 8
therefore, equation if the line is y = -3x + 8

In triangle DEF, segment DJ is a perpendicular bisector of side EF. If EJ is 3y-8 and JF is 7y-40, what is the length of JF?
Answers
Answer: The length of JF = 16 units.
Step-by-step explanation:
Given: In triangle DEF, segment DJ is a perpendicular bisector of side EF.
i.e. DJ is perpendicular to EF and DJ divides EF into two equal parts EJ and JF. [The perpendicular bisector is a line that is perpendicular to a line segment and splits it into two congruent segments.]
If EJ is 3y-8 and JF is 7y-40.
Then, [tex]3y-8=7y-40[/tex]
[tex]\Rightarrow\ 7y-3y=40-8\\\\\Rightarrow\ 4y=32\\\\\Rightarrow\ y=8 \text{ [Divide both sides by 4]}[/tex]
JF= 7(8)-40 =56-40= 16 units
Hence, the length of JF = 16 units.

Step-by-step explanation:
something is represented as a function when none of the inputs (x) repeat, but the outputs (y) change. the graph for letter G has repeating x values, but the y values don't change when an x repeats. however, the graph for letter H has repeating inputs (x), but the outputs are different, even with the same input.
that's why parabolas aren't functions (if you know what those are).
