Answer:
These lines are linear lines.
Step-by-step explanation:
Linear lines are straight lines. We can determine if a line is linear in one of a few ways, three being:
By looking at the lines. If they are straight, then they are linear.
By looking at a graph. If there is a constant rate of change within the graph (between the points), then the line is linear. A constant rate of change is when something is changing at a constant, or not-changing number. For example, if the rate of change is 3 (+3 or -3), and never any other number, then the line is linear.
By solving the equation. For a line to be linear, it has to be able to fit in the slope-intercept form (y = mx + b) (without any exponents). If the equation does not work for the line, then the line is likely non-linear. A linear line may also have two expressions that are equal to each other. It's a little hard to see the entire second equation in the picture, but it appears to be 4x - 7. Meanwhile, the first equation is -2x + 5. Clearly, both lines are linear as they both fit in/follow the slope-intercept form. The m's are: -2 and 4, and the b's are 5 and -7.

for the equation x + y = 3. How many possible values for x are there if x and y are both whole numbers?
A.2
B.3
C.4
Answers
Answer:
A
Step-by-step explanation:
Because it is 2+1 and 3+0, those are the only solution, therefore A is correct
======================================================
Explanation:
The set of whole numbers is {0, 1, 2, 3, ...}
So we include 0 and any positive number that doesn't have decimal or fractional components to it. Negative values are not included.
If we plug in x = 0, then x+y = 3 solves to y = 3If we plug in x = 1, then x+y = 3 solves to y = 2If we try x = 2, then x+y = 3 solves to y = 1Lastly, x = 3 leads to y = 0Whatever you pick for x, the y value must add to it to get 3. Both x and y must be numbers from the set of whole numbers.
There are four cases shown in the bullet points above, so we have four different solutions. We can't move onto x = 4 because the y solution would be y = -1, but -1 is not in the set of whole numbers.

After a parade, a group of volunteers is helping to pick up the trash along a 2-mile stretch of a road. The group decides to divide the length of the road so that each volunteer is responsible for cleaning up equal-length sections. Find the length of a road section for each volunteer if there are 8 volunteers
Answers
Answer: 0.25 miles
Step-by-step explanation:
When solving a word question, look for certain words that tell you what you should be solving for, and how to solve it.
In this problem, the group DIVIDES the length of the road EQUALLY, which tells you that in order to solve the problem, you must divide the length of the road by the number of volunteers.
The road is 2 miles long, and there are 8 volunteers, so
8/2 = 0.25
Thus, each person must clean 0.25 miles of road.
Using proportions, it is found that the length of road section for each volunteer will be of 0.25 miles.
-----------------------
This question is solved by proportions, using a rule of three to find the length of the road assigned to each volunteer, as each volunteers will be assigned an equal length of the road.In total, the length of the road is of 2 miles. Thus, 8 volunteers are responsible for 2 miles. For how many miles will a single volunteer be responsible?-----------------------
The rule of three is given by:
8 volunteers - 2 miles.
1 volunteer - x miles
Applying cross multiplication:
[tex]8x = 2[/tex]
[tex]x = \frac{2}{8}[/tex]
[tex]x = \frac{1}{4}[/tex]
[tex]x = 0.25[/tex]
The length of road section for each volunteer will be of 0.25 miles.

Mike and Kate plan to save money for their wedding over a 20 month period. They will need to save $8,000 to help pay for the wedding. They set aside the same amount each month. After a year they saved $4,000. Mike and Kate know they must adjust their plan in order to meet their goal, so they came up with the following options:
Option A: Stay with saving the same amount they've been saving each month but postpone the wedding 2 months.
Option B: Increase the amount of money they save each month by $80 from what they've been saving.
Which of the following is a true statement?
Answers
Answer:
The Answer is Actually D. I just took the Test and got it Correct! have a Great Day.!!
Step-by-step explanation:
The true statement is that both plans will not amount to $8000 in the end
The target savings is given as:
[tex]Target = \$8000[/tex]
The amount saved after a year is given as:
[tex]Savings = \$4000[/tex]
Start by calculating the amount saved each month (by dividing the saved amount by 12)
[tex]Monthly = \frac{\$4000}{12}[/tex]
For option (A): To increase the wedding by 2 months.
This means that the duration of savings would be 22 months.
So, the estimated savings would be
[tex]Estimate= \frac{\$4000}{12} \times 22[/tex]
[tex]Estimate= \$7333[/tex]
For option (B): Increase savings by $80.
This means that they have 8 months to complete their savings
The estimated savings would be
[tex]Estimate= \$4000 + (\$80 + \frac{\$4000}{12}) \times 8[/tex]
[tex]Estimate= \$7307[/tex]
For both plans, the estimated savings are short of the target savings of $8000.
Hence, none of the plans would amount to $8000 in the end

What is an equation of the line that is parallel to the one shown and passes through (6, −5)?
A. y=−23x−1
B. y=32x−4
C. y=23x+1
D. y=−32x+4
Answers
Answer:
D is the answer
The equation in slope-intercept form, of the line that passes through (6, -5) and is parallel to the line given is: D. [tex]\mathbf{y = -\frac{3}{2} x + 4}[/tex]
Recall:
Slope of two lines that are parallel to each other will always be the same value.Slope = rise/runFrom the graph shown, the slope (m) of the line is [tex]-\frac{3}{2}[/tex].
Thus, the line that passes through (6, -5) and is parallel to the line in the graph will have the same slope of [tex]-\frac{3}{2}[/tex].
Write the equation in point-slope form by substituting (a, b) = (6, -5) and m = -3/2 into y - b = m(x - a).
Thus:[tex]y - (-5) = -\frac{3}{2} (x - 6)\\\\y +5 = -\frac{3}{2} (x - 6)[/tex]
Rewrite in point-slope form as y = mx + b
[tex]y +5 = -\frac{3}{2} (x - 6)\\\\y + 5 = -\frac{3}{2} x + 9\\\\y = -\frac{3}{2} x + 9 - 5\\\\\mathbf{y = -\frac{3}{2} x + 4}[/tex]
Therefore, the equation in slope-intercept form, of the line that passes through (6, -5) and is parallel to the line given is: D. [tex]\mathbf{y = -\frac{3}{2} x + 4}[/tex]Learn more here:
