what does this mean 4x + 6y=9
12x + 18y=27
Answer: Infinite solutions
Step-by-step explanation:
Solve4x+6y=9for x:
4x+6y=9
4x+6y+−6y=9+−6y(Add -6y to both sides)
4x=−6y+9
4x /4 = −6y+9 /4
(Divide both sides by 4)
x= −3 /2 y+ 9 /4
Substitute
−3 /2 y+ 9 /4
for x in 12x+18y=27:
12x+18y=27
12( −3 /2 y+ 9 /4 )+18y=27
27=27(Simplify both sides of the equation)
27+−27=27+−27(Add -27 to both sides)
0=0

*7. Mrs. Martin rents a car for $36 plus $0.15 per mile. His budget is $60.
How many miles can she drive? *
A. 160 miles
B. 150 miles
C. 140 miles
D. 130 miles
Answer:
The answer is A
Step-by-step explanation:
60-36= 24/0.15=160
9514 1404 393
Answer:
(a) 160 miles
Step-by-step explanation:
Let m represent the number of miles Mrs Martin drives. Her rental cost is ...
c = 36 +0.15m
She wants to find m when that is equal to $60.
60 = 36 +0.15m
24 = 0.15m . . . . . . . subtract 36
24/0.15 = m = 160 . . . . divide by the coefficient of m
Mrs. Martin can afford to drive up to 160 miles.

Find the equation of the line.
Use exact numbers.
Y=“blank”x+ “blank”
Answer:
y=mx+b
b= y intercept
mx=slope
First lets find the y intercept = the y intercept is 3
Now lets find the slope = the slope is 3x because each time it goes 3 up it goes one right
So the answer is y=3x+3
EXTRA POINTS---Set up an equation and find the value of x.
Answer:
13) x = 30
14) x = 22.5
15) x = 36
Step-by-step explanation:
13) 4x+2x = 180
6x = 180
x = 30
14) 3x+5x = 180
8x = 180
x = 22.5
15) 2x+3x+2x+3x = 360
10x = 360
x = 36
Answer:
x=36

Savannah deposited $500 into an account that pays simple interest at a rate of 5% per year. How much interest will she be paid in the first 7 years?
Answer:$266
Step-by-step explanation:
Cameron :
r = 4 3/8% = 0.04375
P = 7400
For account compounded continuously :
A = Pe^it
i = interest ; t number of years ;
A = 7400 * e^0.04375*7
A = 7400 * e^0.30625
A = 10051.581
Savanna:
r = 4 3/4% = 0.0475
P = 7400
A = P(1 + r/n)^nt
n = number of compounding times per period
A = final amount ; P = initial investment
Compounded daily :
A = 7400(1 + 0.0475/365)^365*7
A = 7400(1 + 0.0001301)^2555
A = 7400(1.0001301)^2555
A = 7400 * 1.3942879
A = 10317.731
Difference :
$(10317.731 - 10051.581)
= $266.15
= $266 (nearest dollar)

Nicholas has a pepper shaker in the shape of a cylinder. It has a radius of 9 mm and height of 32 mm. How much pepper will for in the shaker
By using the fοrmula fοr the vοlume οf a cylinder, the pepper shaker can hοld apprοximately 8,159.15 cubic millimetres οf pepper.
What is the vοlume οf a cylinder ?The fοrmula tο calculate the vοlume οf a cylinder:
V = πr²h
where:
V = vοlume
r = radius
h = height
Tο calculate the vοlume οf the pepper shaker, we need tο use the fοrmula fοr the vοlume οf a cylinder.
In this case, we have:
r = 9 mm
h = 32 mm
Sο the fοrmula becοmes:
V = π(9 mm)²(32 mm)
V = π(81 mm²)(32 mm)
V = 81π(32) mm³
V ≈ 8,159.15 mm³
Therefοre, the pepper shaker can hοld apprοximately 8,159.15 cubic millimeters (οr milliliters) οf pepper.
