Line perpendicular to y = -2x - 7 when it passes the points (-2,-3)
Answer:
The line is y = 1/2x - 2
Step-by-step explanation:
The required line will have a slope of -1/-2 = 1/2.
Using the point slope form of a line:
y - (-3) = 1/2(x - (-2))
y + 3 = 1/2x + 1
y = 1/2x - 2.

The corner store sells apples at a rate of $1.25 per apple . if olivia has $10.00 dollars, how many apples can olivia buy
Answer:
8 Apples
Step-by-step explanation:
You have ten dollars, and a fee of 1.25 per apple to buy,
to find the total number of apples oliva can buy, you divide the total allowance by the cost per apple
in this case,
10.00/1.25
and you get a solution of 8 Apples.
Answer:
8 apples

what is 8+4d=5d i really need help
Answer:
d = 8
Step-by-step explanation:
Given
8 + 4d = 5d ( subtract 4d from both sides )
8 = d
Answer:
d=8
Step-by-step explanation:
8+4d=5d
1. subtract 8 from both sides > 8+4d-8=5d-8
2. simplify > 4d=5d-8
3. subtract 5d from both sides > 4d-5d=5d-8-5d
4. simplify again > -d = -8
5. divide both sides by -1 > -d/-1 = -8/-1
6. simplify again > d=8

Use a calculator or chart to find the z-score.
P(Z > z) = 0.60
P(Z < z) = 0.40
z = -0.253
Find the time associated with the z-score.
z = (x − μ) / σ
-0.253 = (x − 4) / 3

Chris wants to fence a square area of his yard for his dogs. if he wants the area of the square to be 121 square feet, what does the perimeter of the square need to be?
please i'm about to fail
Answer: the perimeter of the square is 44
Answer:
44 ft
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the side length )
Here A = 121, thus
s² = 121 ( take the square root of both sides )
s = [tex]\sqrt{121}[/tex] = 11
Perimeter = 4 × 11 = 44 ft

Li walks at a constant rate of 7 ft. in 4 seconds. The table shows the relationship of feet to seconds. What is the constant of proportionality for the relationship of feet to minutes? (1 minute=60 seconds) *
10 points
Answer:
The rate is 1.75 feet/seconds or 105 feet/minute.
Step-by-step explanation:
Given that,
Li walks at a constant rate of 7 feet in 4 seconds
To find the constant of proportionality, divide 7 feet by 4 seconds.
So,
[tex]k=\dfrac{7\ \text{feet}}{4\ \text{seconds}}\\\\k=1.75\ \text{ft/s}[/tex]
1.75 ft/s is the constant of proportionality
We know that, 1 minute = 60 seconds
k = 105 feet/minute
So, the rate is 1.75 feet/seconds or 105 feet/minute.

CAN SOMEONE PLEASE HELP ME ASAP PLEASEE ANYBODY LITERALLY ANYONE OUT THERE PLEASE. Determine m∠FNT and Determine m∠KTU.
Answer:
Angle FNT = 120 Degrees because the angles labeled 7a+50 and 14a-20 are the same because the lines are parralel so you can set them equal to eachother 7a+50=14a-20 and find that a=10 After this you plug 10 into either 7a+50 and 14a-20 to get 120. You know Angle FNT is 120 degrees because it is directly across from 7a+50 which means they are the same. Then the measure of Angle KTU is 60 because Angle KTN + Angle KTU needs to add up to 180.
Jerry is taking care of a vacant lot in his neighborhood. There are approximately 64 thistle weeds m the local
He decided to try a homemade weed killer his grandmother suggested. Five weeks later, the thistles have
decreased by 75%. Approximately how many thistles are in the vacant lot now?
Answer:
16
Step-by-step explanation:
To be able to find the number of thistles that are in the vacant lot now using the information provided, you have to calculate the 75% of 64 and then, subtract that number from 64:
64*0.75=48
64-48=16
According to this, the answer is that there are 16 thistles in the vacant lot now.

10. Calculate the speed of waves in a puddle that are .15 apart and made by tapping the water
surface twice each second.
Since the waves are 0.15 apart and made by tapping the water surface twice each second the speed of waves in the puddle is 0.6 m/s
To answer the question, we need to know what a wave is
What is a wave?A wave is a disturbance in space which carries energy from one point to another
What is the speed of a wave?The speed of a wave v = fλ where
f = frequency and λ = wavelengthWavelength of waveSince the puddles are 0.15 m are and we know that this is the distance from crest to crest.
Also, the distance from crest to crest is λ/2
So, λ/2 = 0.15
λ = 2 × 0.15 m
= 0.3 m
Frequency of wave
Also, since the tapping by the water surface is done twice each second, the frequency, f = 2 times/s = 2 Hz
Speed of waves in puddleSubstituting the values of the variables into the equation, for speed, we have
v = fλ
v = 2 Hz × 0.3 m
v = 0.6 m/s
So, the speed of waves in the puddle is 0.6 m/s

Triangle MNO has vertices with coordinates (–8, 2), (–5, 5), and (5, – 2).
Which of these equations represents the line that passes through point N and is perpendicular to the line passing through points O and M?
y = x + 3
y = x - 3
y = -x + 3
y = -x - 3
Answer:
i think its c
Step-by-step explanation:
The equation of a straight line is represented as: [tex]y = mx + c[/tex]
The equation of the line is: [tex](c)\ y = -x +3[/tex]
The coordinates are given as:
[tex]M = (-5,5)[/tex]
[tex]N = (5,-2)[/tex]
[tex]O = (-8,2)[/tex]
First, we calculate the slope of line MO using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, we have:
[tex]m = \frac{2-5}{-8--5}[/tex]
[tex]m = \frac{-3}{-3}[/tex]
[tex]m = 1[/tex]
The line that passes through N is perpendicular to MO.
This means that, the slope (m2) of the line is:
[tex]m_2 = -\frac 1m[/tex]
So, we have:
[tex]m_2 = -\frac 1{1}[/tex]
[tex]m_2 = -1[/tex]
The equation of the line is then calculated as:
[tex]y = m_2(x - x_1) + y_1[/tex]
Where:
[tex]m_2 = -1[/tex]
[tex]N = (5,-2)[/tex] --- [tex](x_1,y_1)[/tex]
So, we have:
[tex]y = -1(x -5) - 2[/tex]
[tex]y = -x +5 - 2[/tex]
[tex]y = -x +3[/tex]
Hence, the equation of the line is: [tex](c)\ y = -x +3[/tex]
