Step-by-step explanation:
What is the x - and y - intercepts of -3y = 7x - 21
Answer: x-intercept = (3,0); y-intercept = (0,7)
Step-by-step explanation:
-3y = 7x - 21
y = -7/3 x + 7 (divide both sides by -3)
y-intercept = (0,7) (y = mx + b; b is always y-intercept)
0= -7/3 x + 7 (plug in 0 for y to get x-intercept)
-7/3x = -7 (subtract 7 from both sides)
x = 3 (divide both sides by -7/3)
x-intercept = (3,0)

A 5 foot tall person walks away from a 12 foot tall lamppost at a constant rate of 4 feet per second. What is the rate that the tip of the shadow moves away from the lamppost when the person is 9 feet away from the pole?
Solution :
Given :
The height of the person is 5 foot.
The height of the lamppost is 12 foot.
Speed of the person away from the lamppost = 4 ft/s
Let the distance of the tip of the shadow of the perosn to the pole at t seconds after the person started walking away from the pole be d(t).
By similarity of the triangles, we see that
[tex]$\frac{12}{d}=\frac{5}{x}$[/tex] .................(i)
Here x is the distance from the person to the tip of the shadow. As it is given the speed of the person is 4 ft/s, then the distance of the person from the pole 4t. So we have,
x = d - 4t .............(ii)
Putting (ii) in (i) and solving for d is
d(t) = 6.85 t
So now if we derive d(t), we will get the wanted rate of the tip of the shadow.
∴ d'(t) = 6.85 ft/s

One hour on earth is four hours on planet S.
If 240 hours on planet S have passed how many hours has it been on earth?
Answer:
The answer is 60 hours.
Step-by-step explanation:
We could use proportions to solve.
[tex] \frac{1 \: hour \: on \: earth}{4hours \: on \: planet \: s} = \frac{x}{240hours \: on \: planet \: s} [/tex]
[tex]4 \times x = 4x \\ 1 \times 240 = 240[/tex]
[tex] \frac{4x}{4} = \frac{240}{4} \\ x = 60[/tex]

What match the decimal with its equivalent percent.
0.0402
Answer:
The answer would be 4.02% or simply 4%
Step-by-step explanation:
When you have a decimal like 0.0402 for example you move the decimal point to the right twice to get the percentage. Another example would be if you had the decimal 0.08 you would have the percentage 8%. Hope this helped!! If you have the time please mark brainlest?

please help. What is the solution to the system of equations below?
y = 3x – 2
X + y = 6
Answer:
A. (2,4)
Step-by-step explanation:
use the substitution method.
for the second equation, subtract x on both sides to get y = 6-x
substitute that into the first equation
6 - x = 3x - 2
add x on both sides: 6 = 4x-2
add 2 on both sides: 4x = 8
divide by 4: x = 2
y = 6-2 = 4
Answer:
A. (2, 4)

Solving systems of equations using substitution/eliminationSolving systems of equations by graphingStep-by-step explanation:
Step 1: Define systems
y = 3x - 2
x + y = 6
Step 2: Solve for x
Substitution
Substitute in y: x + 3x - 2 = 6Combine like terms: 4x - 2 = 6Add 2 to both sides: 4x = 8Divide 4 on both sides: x = 2Step 3: Solve for y
Define original equation: x + y = 6Substitute in x: 2 + y = 6Subtract 2 on both sides: y = 4Step 4: Graph systems

2x + 5y + 11 = 0
3x - y-8= 0
Answer:
x = 1[tex]\frac{12}{17}[/tex], y = -2[tex]\frac{15}{17}[/tex]
Step-by-step explanation:
2x + 5y + 11 = 0 --- Equation 1
3x - y - 8 = 0
15x - 5y - 40 = 0 --- Equation 2
Equations 1+2: 2x + 5y + 11 + 15x - 5y - 40 = 0 + 0
17x - 29 = 0
17x = 29
x = 29 ÷ 17
x = 1[tex]\frac{12}{17}[/tex]
Substitute x = 1[tex]\frac{12}{17}[/tex] into Equation 1:
2x + 5y + 11 = 0
2(1[tex]\frac{12}{17}[/tex]) + 5y + 11 = 0
3[tex]\frac{7}{17}[/tex] + 5y = -11
5y = -11 - 3[tex]\frac{7}{17}[/tex]
= -14[tex]\frac{7}{17}[/tex]
y = -14[tex]\frac{7}{17}[/tex] ÷ 5
y = -2[tex]\frac{15}{17}[/tex]
which function represents the graph?
Answer:
y=3sin(x)
Step-by-step explanation:
The best way to check if it's right is to use a graphing calculator. The negative trigonometric functions are going upwards from 1pi to 2pi and the positive ones are going downwards from 1pi to 2pi. Since the cos sign is shifted two units left, we can assure that 3sin(x) gives the most accurate answer.

David is buying a cheese wheel priced at $14 before tax. The store charges 8% sales tax.
What is the total price, including tax, David pays for the cheese wheel?
Answer:
$15.12
Step-by-step explanation:
1. Find the total amount of sales tax. This can be done by multiplying the before tax price by the sales tax percentage.
14 x 8% = 1.12
2. Add the sales tax amount back to the price.
14 + 1.12 = $15.12
how to tell if a sequence is arethmetic
Answer:
If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence. The constant difference in all pairs of consecutive or successive numbers in a sequence is called the common difference, denoted by the letter d.
Step-by-step explanation:
JAB Consulting received a promissory note of $13,500 at 7% simple interest for 15 months from one of its customers. After 6 months, Grove Isle Bank discounted the note at a discount rate of 6% Calculate the proceeds (in $) that JAB Consulting will receive from the discounted note. (Round your answer to the nearest cent.)
Answer:
Amount = $14,024 (Approx)
Step-by-step explanation:
Given:
Amount received P = $13,500
Rate r = 7% = 0.07
Time t = 15 month = 15/12 = 1.25 = year
Discount rate = 6% = 0.06
Computation:
Maturity value = P[1+rt]
Maturity value = 13,500[1+(0.07)(1.25)]
Maturity value = $14,685.61
Time = 15 month - 6 month
Time = 9 month = 9/12 = 0.75 year
Amount = MV[1-dt]
Amount = 14,685.61[1-(0.75)(0.06)]
Amount = $14,024 (Approx)

how do you find y-intercept of the line of a graph
Answer:
If you know what the formula y = mx +b is, then you know that mx is the slope and b is the y-intercept.
Let`s suppose the equation is y = 2x + 1. The line should be intersecting with the coordinate (0, 1) on it`s way across.
The y axis will ALWAYS be the vertical line. Whatever coordinate the line crosses on the y-axis is the y-intercept.
The y-intercept can also be a negative number.

Use the following graph to determine the solution(s) of:
y= x^2- x - 6
Answer:
-2 and 3
Step-by-step explanation:
The x-intercepts or where the graph cuts the x-axis represents the zeros of y = x² - x - 6.
Thus, the zeros are -2 and 3. This is where the graph cuts the x-axis.
Therefore, the solutions of the graph are -2 and 3.
