According to the proportional relationship, how much money did the song bring in from sales in the first week if the pop star ea
rned $800 that week?
Describe what the point (0,0) on the graph represents in terms of the situation being described by the graph.
Which point on the graph represents the amount of money the pop singer gets for $1 in money brought in from sales of the song by the store? (*This is the unit rate)
$800 = x/_____ (For prt.1)

Answer:
Step-by-step explanation:
Given that,
The diameter of the cylinder, d = 8 cm
Radius, r = 4 cm
Height of the cylinder, h = 16.8 cm
We need to find the surface area of this cylinder. The formula for the surface area of the cylinder is given by :
So, the surface area of the cylinder is
Answer x=6 and y=10
Explanation:
Replace each variable in turn with 0 and solve
5x+3y=30 Put zero in place of x and solve for y
5(0)+3y=30
y=10 The y- intercept is 10
5x+3y=30 Put zero in place of y and solve for x
5x+3(0)=30
x=6 The x-intercept is 6
Answer:
Step-by-step explanation:
first problem:
3 is a solution to x^2=9, so to a, b, c and d
second problem
-2 is a solution to:
a, b, c and d because (-2)^2=4, 4=4, b) 5*(-2)^2=5*4=20 and so on
basically to all choices
the third, solve the equations:
x^2=1, =
, x=1
x^2=81 sqrtx^2=sqrt81, x=+and -9
4x^2=1 divide by 4 , x^2=1/4, x=+&- 1/2 (plus si minus 1/2, amindoua solutiile sint valabile)
3x^2=75, we divide by 3, we get x^2=25, x=+&-5
49x^2=121 , x=+and- 11/7
25x^2=225 divide by 25, x^2=9, x =+and - 3
36x^2=144 we divide by 36, we get x^2=4, x = +and- 2
x^2-0.25=0 x^2=0.25, x=+and - 1/2
2x^2-0.32=0 , 2x^2=0.32, x^2=0.16 ( i divided by 2) , x=+and- 2/5
4x^2=0.04, divide by 4, x^2=0.01, x=+and - 0.1
3x^2=10.8, divide by 3, x^2=3.6, x=+and - 1,89
for the : determinati solutiile ecuatiilor
a) (x-1)^2=49, do the quadratic, you get x=8 and -6
due to the length of this page, i cant explain every step
b) (2x+1)^2=81, you get x= 4 and -5
c)(3x-1)^2=121, do the quadratic, x=- 10/3 and +4
d) 3(x-3)^2=48, we divide by 3 first , (x-3)^2=16, we get x=7 and -1
e)5(x+2)^2=45 we divide by 5, (x+2)^2=9, x=+1and -5
f) 7(2x-1)^2=175 we divide by 7 and we have (2x-1)^2=25 x=+3 and -2
Determine x belong to R
a) 1/9 x^2=16, we multiply 9*16=144, x^2=144, x=+and - 12
1/100x^2-1/64=0, or 1/100 x^2=1/64, x=+and - 5/4
1/25 x^2=0.49, x^2=0.49*25=12.25, x=+ and - 7/2
