Write the equation of the line that has a slope of 4/5 and a y-intercept of -8.
Answers
The equation of any staright line can be written as y = mx + c , where m is its slope and c is its y - intercept . hence, equation of line with slope = 4/5 and y - intercept = -8 is,
→ y = 4/5x - 8
→ m - c = 4/5 + 8 = 12/5

The new dolphin tank at the city aquarium is in the shape of a rectangular prism. It is long by wide by deep. To make the tank livable for the dolphins, the aquarium workers treat the water using bags of salt. The amount of water a bag of salt can treat is known in cubic feet.
(a) Find the volume of water in the tank in cubic feet.
(b) To make the tank livable for the dolphins, a bag of salt must be added for each 19.4ft$ of water. The aquarium doesn't have any salt on hand and the salt can only be purchased in whole bags. How many bags of salt must be purchased to treat the water?
(c) If each bag of salt costs $4.85, how much must the aquarium pay for salt to treat all the water in the new dolphin tank?
answer quickly
Answers
The volume of water in the tank is 35,100 cubic feet.
What is the volume of the rectangular prism?Volume = length × width × height
We have the following parameters based on the information provided;
Length = 20 meters
Width = 13 meters
Height = 5 meters
Substitute the values into the formula to get
Volume = 20 × 13 × 5
Volume = 1300 cubic meters
Convert the cubic yard into cubic feet
1 cubic yard = 27 cubic foot
⇒ 1300 yards = x
⇒ x = 27 × 1300
⇒ x = 35,100 cubic feet
Therefore, the amount of water a bag of salt can treat is 35,100 cubic feet

For any linear function f(x) = mx + b, when does kf(x) = f(kx)?
Answers
Only when b = 0 or k = 1.
If f(x) = mx + b, then
f (kx) = m (kx) + b = mkx + b
while
k f(x) = k (mx + b) = kmx + kb
The two expression are identical only if
kb = b ===> kb - b = 0 ===> b (k - 1) = 0 ===> b = 0 or k = 1

An object is thrown upwards with a speed of 20 m/s. After t seconds, its height can be solved using the formula h = 20t - 4.9t2 where h is the height and t is the time. After how many seconds is the object 19.6 meters high?
Answers
Step-by-step explanation:
h= 20t - 4.9t^2
when h=19.6m
19.6=20t - 4.9t^2
4.9t^2 -20t+19.6=0
solving quadratically
t= 1.64 seconds or t= 2.45 seconds

A package of 6 pairs of insulated gloves costs $38.94. What is the unit price of the pairs of gloves? The unit price is $ per pair of gloves.
Answers
Answer:
6.49
Step-by-step explanation:
6 pairs of insulated gloves cost $38.94
That means 6 x (price of one glove) = 38.94
Let's say the price of on glove = x
The equation is :
6x = 38.94
x = 38.94 ÷ 6 (divide all sides by 6)
x = 6 + (2.94 ÷ 6) (Splitting numbers to multiples of 6)
x = 6 + 0.4 + ( 0.54 ÷ 6) (Splitting numbers to multiples of 6)
x = 6 + 0.4 + 0.09 (Adding all sums)
x = 6.49
Each pair of gloves cost 6.49

Hey there!
10x ÷ 8 = 18
MULTIPLY 8 to BOTH SIDES
10x ÷ 8 * 8 = 18 * 8
SIMPLIFY IT
NEW EQUATION: 10x = 144
DIVIDE 10 to BOTH SIDES
10x/10 = 144/10
CANCEL out: 10/10 because it gives you 1
KEEP: 144/10 because it helps simplify for the x-value
x = 144/10
x = 144 ÷ 2/10 ÷ 2
x = 72/5
Therefore, your answer is: x = 72/5

Which equation shows that the product of a square matrix A and its identity matrix I is A?
Answers
Answer:
Option B
Step-by-step explanation:
The multiplication process of matrices works by multiplying the first row of the first matrix by the first column of the second matrix. The same goes with the second row of the first matrix by the second column of the other matrix. Below is the solution why option B is the correct answer.
[tex]A = \left[\begin{array}{ccc}8&11\\13&5\\\end{array}\right][/tex]
[tex]B = \left[\begin{array}{ccc}1&0\\0&1\\\end{array}\right][/tex] ← This is the Identity Matrix.
The attached screenshot shows the solution of the multiplication process. In essence, if you multiply any matrix by the identity (Matrix B), you should end up with your original matrix. Thus, multiplying Matrix A by the Identity matrix results in the same values as Matrix A.
Therefore, the correct answer is B.

How can you tell if an equation (for example, x=16+3y (don’t solve this)) will be represented by a straight line when graphed on a coordinate plane? Is there an easy way to tell or how do you figure that out?
Answers
Answer:
I know it is a straight line because I can convert it into standard or slope intercept form. An example of when something isn't a straight line is like y=|x|.
x=16+3y
-3y=-x+16
y=1/3x-16/3
If the variable looks like x^2 or something, then it will not be a straight line.
