Answer:
Y = 7/15x + 6/5
Step-by-step explanation:
7x - 15y = -18
7x = 15y - 18
7x + 18 = 15y
7/15x + 6/5 = y
Hope this helps! Pls give brainliest!
We can convert the line 7x − 15y = –18 into slope-intercept form (y = mx + c) by making y the subject of the equation
7x - 15y = - 18
7x + 18 = 15y
⁷/₁₅ x + ¹⁸/₁₅ = y
∴ the slope-intercept form of 7x − 15y = –18 is y = ⁷/₁₅ x + ⁶/₅
What is the slope of the line on the graph?
Enter your answer in the box.
Answer: The slope of the line is 6.
You can use the distance formula to find the slope (Y2-Y1/X2-X1). You can plug in any two points seen on the graph into the formula. I will use (0,-1) and (1,5). When I plug in the values, 5-(-1)/1-0=6/1=6. So the slope of the line is 6.

The total cost after sales tax to fix Azar’s computer is represented by the expression 0.08 (55h) + 55h, where h represents the number of hours it takes to fix Azar’s computer.
What percentage sales tax is Azar being charged? Explain your answer using 1-2 sentences
What part of the expression represents the dollar amount of sales tax Azar must pay?
Answer:
these are 5 points look clearly.XD
The percentage sales tax is 8%.
The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).
Given,
The total cost after sales tax to fix Azar’s computer is represented by the expression:
- 0.08 (55h) + 55h
where h represents the number of hours it takes to fix Azar’s computer.
We need to find out what percentage of sales tax is Azar being charged.
and what part of the expression represents the dollar amount of sales tax Azar must pay.
What represents sales taxes?It is mostly represented by a percentage.
We have,
100% = 100/100 = 1
50% = 50/100 = 1/2 = 0.5
25% = 25/100 = 1/4 = 0.25
20% = 20/100 = 1/5 = 0.2
We have,
- 0.08 (55h) + 55h
The sales tax is also charged according to the number of hours so,
In the expression 0.08 can be written as a percentage.
0.08 = 8 /100 = 8%
The percentage sales tax is 8%.
Now,
0.08 55(h) means the sales tax Azar must pay.
For 1 hour,
0.08 x 55 = 4.4 is the sales tax.
For 2 hours,
0.08 x (55x2) = 0.08 x 110 = 8.8.
And so on,
So,
The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).
Thus,
The percentage sales tax is 8%.
The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).

A line passes through point (-2, 5) and has a slope of 3. Points A(x 3) and B(-2, y lie on the line.
The value of xis
and the value of yis
Answer:
x = -8/3
y = 5
Step-by-step explanation:
Finding the equation of the line:
y = 3x +c
Substituting (-2,5) into 'y=3x+c':
5 = -6 + c
c = 11
Hence,
y = 3x + 11
For finding x:
Substituting (x, 3) into 'y = 3x +11':
3 = 3x + 11
3x = -8
x = -8/3
For finding y:
Substituting (-2, y) into 'y = 3x + 11':
y = -6 + 11
y = 5

Mr. Mole's burrow lies 5 meters below the ground. He started digging his way deeper into the ground, descending 3 meters each minute. Graph the relationship between Mr. Mole's elevation relative to the ground (in meters) and time (in minutes).
coordinates please!
Answer:
See the graph attached
Step-by-step explanation:
Every minute = 3m
At time zero, the depth is zero
Giving coordinates of (0, 0)
At time 1 minute, the depth is 3m
Giving coordinates of (1, 3)
This gives a linear equation
Slope = Δy/Δx
= (3-0)/(1-0)
= 3/1
= 3
Take any general point (x, y)
The equation of the line is:
(y-0)/(x-0) = 3
y/x = 3
y = 3x

Answer:
D
Step-by-step explanation:
∠1 + ∠2 = 180 {Supplementary angles}
6x + 15 + 3x + 3 = 180
6x + 3x + 15 + 3 = 180
Combine like terms
9x + 18 = 180
Subtract 18 from both sides
9x = 180 - 18
9x = 162
x = 162/9
x = 18
∠2 = 3x +3
= 3*18 + 3
= 54 + 3
∠2 = 57°

4.5 kg equals times one gram
Answer:
4500 gr
Step-by-step explanation:
4.5 kg equals some number (n) times one gram. Solve this for n:
4.5 kg = n(1 gr)
Recall that 1 kg = 1000 gr. Because of this, the equation above becomes
4.5 kg (4.5)(1000 gr)
n = --------------- or ------------------- or 4500 gr
1000 gr 1 gr

Answer:
1.4 acres of grass can be planted.
Step-by-step explanation:
