Answer:
Infinite number of solutions.
Step-by-step explanation:
y = -7x - 2
y + 3 = -7x + 1
Subtract 3 from both sides:
y = -7x - 2
- this is the same as the first equation.
We can put any number of valid combinations of x and y into this equation.
So there are infinite solutions.

A hollow metallic cylinder is made from a metallic sheet of 2.4 cm thickness. The inner
radius of the cylinder is 5.8 cm and the length is 50 cm. Find the volume of the metal used.
step by step explain plz
Answer:
The volume of the metal used is 5277.9 cm³.
Step-by-step explanation:
The volume of a cylinder is given by:
[tex] V = \pi r^{2} h [/tex]
Where:
r: is the radius
h: is the height = 50 cm
The volume of metal ([tex]V_{m}[/tex]) can be found by subtracting the internal volume ([tex]V_{i}[/tex]) from the external volume ([tex]V_{e}[/tex]):
[tex] V_{m} = V_{e} - V_{i} [/tex]
[tex] V_{m} = \pi r_{e}^{2} h - \pi r_{i}^{2} h [/tex]
The external radius is given by the sum of the internal radius with the tickness:
[tex] r_{e} = t + r_{i} [/tex]
Hence, the volume is:
[tex] V_{m} = \pi*50 cm((2.4 cm + 5.8 cm)^{2} - (5.8 cm)^{2}) = 5277.9 cm^{3} [/tex]
Therefore, the volume of the metal used is 5277.9 cm³.

Starbucks opened two new locations. Location A costed $800 to open but makes $100 a month. Location B costed $1200 to open but makes $200 a month. Determine how long it will take for the locations to have made the same amount after paying off their costs and how much that amount is.
Answer:
I think it is A that will take longer but im not 100 percent sure
Step-by-step explanation:
First write an equation:
Location A- 800+100x
Location B- 1200+200x
Then you need to plug numbers in for x
x^2+2x-8=0 complete the square
Answer:
it should be x=2 or x=--4

Step-by-step explanation:
A cuboid consists of 6 sides, 2 sides will be 9*6, 2 more will be 6*4, 2 more will be 6*9
So because there is 2 sides you will multiply the side by 2 so there is another side:
(6*9) * 2 = 108
(4*6) * 2 = 48
(4*9) * 2 = 72
108 + 48 + 72 = 228
What is the difference between an independent variable and a dependent variable in statistics?
Answer:
The cause is the independent variable. In your study, its value is independent of other variables. The affect is the dependent variable. Its value depends on the independent variable being changed.
Step-by-step explanation:
In a large city’s recent mayoral election, 131,506 out of 309,153 registered voters actually turned out to vote. If 20 registered voters are randomly selected, find the probability that 7 of them voted in the mayoral election. Use a TI-83, TI-83 plus, or TI-84 calculator to find the probability.
The probability that 7 of them voted in the mayoral election using the calculator is 0.1455
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
The probability of registered voters actually turned out to vote:
= 131,506/309,153
p = 0.4254
n = 20
From the calculator:
P(X = 7) = 0.14546189
or
P(X = 7) = 0.1455
Thus, the probability that 7 of them voted in the mayoral election using the calculator is 0.1455

Moussa's family took a road trip to the Grand Canyon. Moussa fell asleep after they
had travelled 434 miles. If the total length of the trip was 700 miles, what percentage
of the total trip had they travelled when Moussa fell asleep?
Answer:
38%
Step-by-step explanation:
So first you need to find what 434/700 is because that is when she fell asleep. Divide each side by 2 to get 217/350. Use division to find the decimal. Once you are done with that, you get 0.62. You then subtract 0.62 from 1 because that is the amount of when she fell asleep. 1-0.62=0.38. 0.38 is also 38% so Moussa fell asleep for 38% of the trip.

factor of 9x2 18x + 8?
Factor of 9x^2-18x+8
Answer:
(3x - 2)(3x - 4).
Step-by-step explanation:
9x^2-18x+8
Use the 'ac' method:
9 * 8 = 72.
We need 2 numbers whose product is + 72 and whose sum is -18
These are -12 and -6 so we rewrite the expression as:
9x^2 - 12x - 6x + 8 Now we factor by grouping:
= 3x(3x - 4) - 2(3x - 4) The 3x - 4 is common so we have:
(3x - 2)(3x - 4).
The factor of the quadratic expression 9x² - 18x + 8 will be (3x - 2) and (3x - 2).
What is factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The quadratic expression is given below.
⇒ 9x² - 18x + 8
Factorize the quadratic expression, then the factors are given as,
⇒ 9x² - 18x + 8
⇒ 9x² - (12 + 6)x + 8
⇒ 9x² - 12x - 6x + 8
⇒ 3x(3x - 4) -2(3x - 4)
⇒ (3x - 2)(3x - 4)
Then the factor of the quadratic expression 9x² - 18x + 8 will be (3x - 2) and (3x - 2).
