Write a slope-intercept equation for a line passing through the point (4,7) that is parallel to y=x+1. Then write a
second equation for a line passing through the given point that is perpendicular to the given line.
Answer:
y = x + 3
y = -x + 11
Step-by-step explanation:
When the slopes are parallel they are the same. When slopes are negative, the slope is the negative reciprocal.
Parallel: The slope is 1. This is the coefficient of the x in the equation given. If you do not see a number before the x like in y = x + 1, then number is 1.
Use this form:
y =mx + b Us the slope of 1 to put in for m. Use 4 for x and 7 for y
7 =(1)4 + b Solve for b.
7 = 4 + b Subtract 4 from both sides.
3 = b
The equation for the parallel line is
y = x + 3.
Perpendicular:
y = mx + b This time the slope is -1 Still use 4 for x and 7 for y
7 = (-1)4 + b
7 =-4 + b add 4 to both sides
11 = b
The equation would be y = -x + 11
A mural measures 95 feet long by 285 feet high. Find the ratio of the height to the perimeter of this mural.
The ratio of the height to the perimeter of this mural 57 : 152.
We are given that:
Length = 135 feet
height = 285 feet
Mural is of a rectangular shape
We will first find the perimeter.
Perimeter = 2(l + w)
Perimeter = 2(95 + 285)
Perimeter = 2(380)
Perimeter = 760 feet
We will now find the ratio of the height to the perimeter of this mural.
Height : perimeter = 285 : 760
Reduce to lowest terms
Height : perimeter = 57 : 152
Therefore, we get that, the ratio of the height to the perimeter of this mural 57 : 152.

Is this true
4. When you subtract two numbers, if you reduce the first number in the subtraction by one, the result is one less. For example, 12 – 4 is 8 and 11 – 4 is 7
When you subtract two numbers, if you reduce the first number in the subtraction by one, the result is one less. This is true.
How to calculate the value?It should be noted that in subtraction when you reduce the first number, you will get a value that's lesser by 1.
In this case, if we have 20 - 5 = 15, then 19 - 5 = 14. We can see that 14 and 15 is a difference of 1.
Therefore, when you subtract two numbers, if you reduce the first number in the subtraction by one, the result is one less. This is true.

Angle Relationship
Find mLTSU if SU bisects LTSV,
mLTSU = 4y + 11, and m∠USV = 6y + 5.
< TSU = 4y + 11 = 23 degrees
What does angle relationship mean?
We talk of angle relationships because we are comparing position, measurement, and congruence between two or more angles. For example, when two lines or line segments intersect, they form two pairs of vertical angles
we have to find m < TSU if SU bisects < TSV, m < TSU = 4y + 11, m < USV = 6y + 5
SU bisects < TSV
=> < TSU = < USV
4y + 11 = 6y + 5
-2y = -6
y = 3
< TSU = 4y + 11 = 23 degrees ( put the value of y=3)
∠USV = 6y + 5 = 23 degrees ( put the value of y=3)
Hence ,< TSU = 4y + 11 = 23 degrees

The length of a rectangular garden is 10 feet longer than its width. The garden's perimeter is 188 feet. Find the width of the garden.
Answer: width of the garden is 42
Step-by-step explanation:
let's say "x" = the garden's length
and "y" = the garden's width
the length of the garden is 10 feet longer than its width
x-10=y
the garden's perimeter is 188 feet
we can set up a new equation like this:
2x+2y=188
now we have two equations and we can solve using the system of equations.
x-10=y
add 10 on both sides to isolate "x"
x=y+10
2x+2y=188
substitue x for y+10 in the second equation
2(y+10)+2y=188
expand
2y+20+2y=188
combine like terms
4y+20=188
subtract 20 from both sides
4y=168
divide by four on both sides
y=42
the width of the garden is 42 feet

The two consecutive whole numbers that it lies between are 28 and 29.
What are the consecutive numbers?The consecutive numbers are those number which follow each other continuously in the order from smallest to largest numbers.
Let the two consecutive numbers be x and x + 1
x + x + 1 = 57
Combine like terms;
2x + 1 = 57
Now Subtract 1 from both sides;
2x = 57- 1
2x = 56
Divide both sides by 2
x = 56/2

The distance from the Earth to the Sun is about 1.5 x 108 km, while the distance from the Earth to the
moon is about 3.8 x 105 km. If a scale model of the solar system is constructed so that the distance
from the Earth to the Sun is 100 meters, what will be the distance from the Earth to the moon?
Select one:
O a. 39, 474 m
O b.
39.5 m
O c. 6.36 m
O d. 0.25 m
The distance from the Earth to the moon, in the scale model, is d. 0.25 m
As per the known fact, ratio of measurement in real is equal to the ratio of measurement on scale. Further, ratio will be calculated in this case as -
Distance from Earth to Sun in real : Distance from Earth to Moon in real = Distance from Earth to Sun on scale : Distance from Earth to Moon on scale
Keep the values in mentioned relation to find the distance from Earth to Moon.
1.5×10⁸:3.8×10⁵ = 100:distance from Earth to Moon on scale
Distance from Earth to Moon on scale = 100×3.8×10⁵/1.5×10⁸
Distance from Earth to Moon on scale = 0.25 m

How do we add two integers?To add two integers, we have to keep in mind their signals, if they are the same or different, as follows:
If they have the same signal, we keep the signal and add the numbers.If they have the different signal, we take the signal of the largest absolute number(largest number without the signal), then subtract the amounts.Hence, for item a, we have that:

Using proportions, it is found that the total job cost for Randi is of $6,674.24.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
The total amount of square yards that she needs is given by:
111.02 + 31.82 + 161.92 = 304.76.
The cost per square yard is given by:
15.01 + 3.12 + 3.77 = $21.9.
Hence the total cost is given by:
304.76 x 21.9 = $6,674.24.
