The equations in slope-intercept form is 5y = x -10, y = 7x-4, y = 8x + 9
<h3>What is slope?</h3>
Slope is the ratio of the change in the y-coordinate to the x coordinate.
Analysis:
The equation in slope-intercept form is y = mx + c
where m is slope, c is y intercept
The equation with slope m = 1/5 and intercept c = -2
is y = 1/5x - 2, 5y = x - 10
The equation with slope m = 7 and c = -4
y = 7x - 4
The equation with slope m = 8 and intercept c = 9
y = 8x + 9

Answer:
e. 5.0329 g/mL
Step-by-step explanation:
Density is defined as mass divided by volume of an object. The volume displaced is:
#Density is then calculated as:
#Correct significant figures should correspond to the highest given in the question.
Hence the density of the metal is 5.0329g/mL
hello! your answer is 4. I just completed the assignment and got it correct. Hope it helps.
Answer:
1.
-2 = x/4 + 1
Subtract 1 from both sides:
-2 - 1 = x/4 + 1 - 1
-3 = x/4
Multiply both sides by 4:
-3 * 4 = x/4 * 4
-12 = x
2.
3x+5
3.
X= 12 or 18
This could be read two different ways.
0=2/3x-12
12=2/3x
12÷2/3=x
12*3/2=x
18=x
—-OR—-
0=2/3(x-12)
0=2/3x-8
8=2/3x
8÷2/3=x
8*3/2=x
12=x
Inequalities
Chua pays a monthly fee of $25 for his phone service, plus $0.05 per minute of use.
Let M = number of minutes Chua uses the phone service.
His monthly cost for the phone service is:
C = 25 + 0.05M
The least he has been charged in a month is $89.40. If we want to know the number of minutes he used the service in that month, then we must solve the inequality:
25 + 0.05M ≥ 89.40
Subtracting 25:
0.05M ≥ 89.40 - 25
Operating:
0.05M ≥ 64.40
Dividing by 0.05:
M ≥ 64.40 / 0.05
M ≥ 1288
He has used his phone service at least for 1288 minutes in a month
