Which is a solution to (x - 3)(x+9) = -27?
O x = -9
Ox= -3
O x = 0
O x = 6
Answer: x = 0
Step-by-step explanation:
Take it slow and do one problem at a time. Multiply the first x by the second ( ) and then move on to -3
2x + 9x -3x -27 = -27
combine all like terms
8x - 27 = -27
add 27 to both sides
8x = 0
divide by 8 to get x alone
x = 0
A fish tank at an aquarium has a volume of 1,568 cubic feet and a depth of 8 feet. If the base of the tank is square, what is the length of each side of the tank?
Answer:
14
Step-by-step explanation:
So, if x is length, then x*x*8 is 1568. To solve, you do 1568/8, which gives you 196. The square root of 196 is 14, and 14*14*8 is 1568.

what is the volume of the cube below?
Answer:
9h
Step-by-step explanation:
l x w x h
that's the formula of volume
Answer:
A. 9h
Step-by-step explanation:
The formula for the volume of a cube is:
side * side * side.
We know that each side is the same length, and we know all the sides, but this question has a variable for one side of the cube.
So, we get 3 * 3 * h which is 9h.

6.285 x 10 exponent of 2
Answer:
628.5
Step-by-step explanation
Since it is 10^2 you move the decimal point 2 places to the right.
Answer:
628.5
Step-by-step explanation:
When you have [tex]10^{2}[/tex] that is the same as 100 when you multiply a decimal by 100 you move the decimal two times, that's how I got 628.5

If there are 10 terms of the sequence {2, 7, 12, 17, ...}, what is its mean?
Answer:
24.5
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
The consecutive terms in the sequence have a common difference d
d = 7 - 2 = 12 - 7 = 17 - 12 = 5
This indicates the sequence is arithmetic with sum to n terms
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 5 , thus
[tex]S_{10}[/tex] = [tex]\frac{10}{2}[/tex] [ (2 × 2) + (9 × 5) ]
= 5(4 + 45)
= 5 × 49 = 245 , then
mean = [tex]\frac{245}{10}[/tex] = 24.5

Juan has 35 flower deliveries to make. Every hour he delivers to 3 customers. Which
inequality shows the number of hours (h) when Juan will have less than 10 deliveries
left to make.
A. h - 35 > 3 (10)
B. 35 – 3h < 10
C. 35 + 3h <10
D. 3h – 35 < 10
Answer:
B. 35 – 3h < 10Step-by-step explanation:
Given
Number of flower deliveries = 35Delivery rate = 3 customers per hourNumber of hours = hRemaining deliveries after h hours:
35 - 3hInequality to show the time when less than 10 deliveries left:
35 - 3h < 10Correct choice is B.

What is the value of f(4)?
Leslie analyzed the graph to determine if the function it represents is linear or non-linear. First she found three points on the graph to be (–1, –4), (0, -3), and (2, 5). Next, she determined the rate of change between the points (–1, –4) and (0, -3) to be StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction = StartFraction 1 Over 1 EndFraction = 1. and the rate of change between the points (0, -3) and (2, 5) to be StartFraction 5 minus (negative 3) Over 2 minus 0 EndFraction = StartFraction 8 Over 2 EndFraction = 4. Finally, she concluded that since the rate of change is not constant, the function must be linear. Why is Leslie wrong?
A. The points (–1, –4), (0, –3), and (2, 5) are not all on the graph.
B. The expressions StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction and StartFraction negative 3 minus (negative 5) Over 2 minus 0 EndFraction both equal 1.
C.She miscalculated the rates of change.
D.Her conclusion is wrong. If the rate of change is not constant, then the function cannot be linear.
The reason why Leslie is wrong is because: D. Her conclusion is wrong. If the rate of change is not constant, then the function cannot be linear.
What is a linear function?A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
This ultimately implies that, a linear function is typically used for uniquely mapping an input variable to an output variable, with the pair of points having a constant of proportionality.
Mathematically, the rate of change can be calculated by using this formula;
Rate of change = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Rate of change = (y₂ - y₁)/(x₂ - x₁)
Rate of change = (-3 - (-4))/(0 - (-1))
Rate of change = 1/1
Rate of change = 1
For the other points chosen, the rate of change is given by:
Rate of change = (5 - (-3))/(2 - (-1))
Rate of change = 8/2
Rate of change = 4.
In conclusion, Leslie is wrong is because the rate of change or constant of proportionality for these data points are not the same.
