which of the following straight line is parallel to y = 7 - 2x?
Answer:
Whichever line has a slope of -2
Step-by-step explanation:
rewrite in slope intercept
y=mx+b where m=slope
y=-2x+7
-2 is the slope of the original line
a parallel line will never intersect
the parallel line must have the same slope

120
Step-by-step explanation:
As those two lines are parallel, we can express and equation:

if 20 men working together can finish a job in 20 days then the number of days taken by 25 men of the same capacity to finish the job is
Answer:
20x20 =400 then 400/25 = 16 Days
Step-by-step explanation:
Always multiply the amounts of initial men x initail days
then divide by the new amount of men
With other questions for tag fish and sample fish in pond questions
They ask how many fish are estimated to be on the pond.
= The amount of fish caught next day divided by the amount of fish tagged and found in that same catch.
Then multiplied by the amount of all fish tagged initially the day before.
To find random amount in pool.
This is the same method but reversed.

a. x = 15, y = 40
b. x = 30, y = 40
c. x = 15, y = 20
d. x = 30, y = 20
Answer: a. x = 15, y = 40
Step-by-step explanation:
So we already know that ΔABC and ΔFDE are congruent, which means their angles are equal. Based on this information, we could note that:
∠A = ∠F
∠C = ∠E
∠B = ∠D
Since we already know the measurement of ∠B, we could then conclude that ∠D, or y, is equal to 40°. This leaves us with two possible answers, a or b.
In order to find the value of x, we need to know the measurement of ∠F. And in order to find ∠F, we need to find the measurement of ∠A. We already know that the angles in a triangle sums up to 180°. So we would start as the following.
∠A + ∠B + ∠C = 180
We first substitute the known measurements.
∠A + 40 + 110 = 180
We then add up 40 with 110.
∠A + 150 = 180
We finally substract 150 on both sides of the equation. This gives us the measurement of ∠A.
∠A = 30°
Now that we know ∠A, we could start finding the value of x. So we already know this:
∠A = ∠F
We first substitute each angle with their known measurements.
30 = 2x
We now divide both sides by two. This gives the value of x.
x = 15

What is the area of the shaded region?
Answer
157.44
Step-by-step explanation:
To find area of triangle you have to multiply base times height then divided by 1/2. 19.2 cm being your height x 16.4 cm being your base, then divide by 2.
Answer:
area of the triangle = ½×base×height
½×19.2×16.4 = 157.44
so, the area of the triangle is 157.44cm³

Someone pls help me understand this, i dont know how to change my equation around
Answer:
the answer is the third one k > - 5
Answer/Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
[tex]\frac{1}{4}k+\frac{-3}{4}>-2[/tex]
Step 2: Add 3/4 to both sides.
[tex]\frac{1}{4}k+\frac{-3}{4}+\frac{3}{4}>-2+\frac{3}{4}[/tex]
[tex]\frac{1}{4}k>\frac{-5}{4}[/tex]
Step 3: Multiply both sides by 4.
[tex]4*\frac{1}{4}k>4*\frac{-5}{4}[/tex]
K > -5
So according to this the value of k has to be greater than -5
You can check your answer by substituting the values in for k.
You can use a calculator..
[tex]\frac{-10-3}{4} >-2[/tex]
[tex]\frac{-7-3}{4} >-2[/tex]
[tex]\frac{-1-3}{4} >-2[/tex]
[tex]\frac{0-3}{4} >-2[/tex]

Theo used to drive 60 miles to work each day. His new home is now 20 miles away
from his job. What is the percent of
decrease in the distance Theo travels to
work? Round to the nearest tenth if
necessary.
Answer:
66.6% decrease in distance
Rounded 67%
He is traveling 1/3 of what he used to travel
Step-by-step explanation:
The percentage of decrease in the distance Theo travels to work is 66.7%.
Used concept of percentage;
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating the hundredth part of any quantity is called a percentage.
Given that;
Theo used to drive 60 miles to work each day.
And, His new home is now 20 miles away from his job.
Hence the percentage of decrease in the distance Theo travels to work is,
P = (60 - 20)/60 x 100
P = 40/60 x 100
P = 66.7%
So, The percentage of decrease in the distance Theo travels to work is 66.7%.

A line passes through the points (1, 4) and (3, –4). Which is the equation of the line? y = negative 4 x + 8 y = –2x + 6 y = negative one-foA line passes through the points (1, 4) and (3, –4). Which is the equation of the line? y = negative 4 x + 8 y = –2x + 6 y = negative one-fourth x + 2 y = 2x + 2urth x + 2 y = 2x + 2
Answer:
y = -4x + 8
Step-by-step explanation:
The equation of a line is written in slope-intercept form : y = mx+b
m is the slope
We are given two points, so let's find the slope of the line first:
Slope = ΔY/ΔX = 4 - (-4) / 1 - 3 = 8 / -2 = -4
The slope is -4
So far, our equation is y = -4x + b
We can input a point's x and y value to find b, the y-intercept
Let's use point (1, 4)
4 = -4(1) + b
4 = -4 + b
b = 4 + 4
b = 8
The equation is y = -4x + 8
