Let's solve ~
The given equations are :
[tex]\qquad \sf \dashrightarrow \:x + y = 32[/tex]
and
[tex]\qquad \sf \dashrightarrow \:y = 7x[/tex]
Now, plug in the value of y from equation 2 into equation 1 to find out the value of x ~
[tex]\qquad \sf \dashrightarrow \:x + y = 32[/tex]
[tex]\qquad \sf \dashrightarrow \:x + 7x = 32[/tex]
[tex]\qquad \sf \dashrightarrow \:8x = 32[/tex]
[tex]\qquad \sf \dashrightarrow \:x = 32 \div 8[/tex]
[tex]\qquad \sf \dashrightarrow \:x = 4[/tex]
Now, plug the value of x in equation 2 to find y
[tex]\qquad \sf \dashrightarrow \:y = 7x[/tex]
[tex]\qquad \sf \dashrightarrow \:y = 7 \times 4[/tex]
[tex]\qquad \sf \dashrightarrow \:y = 28[/tex]

What is dilation?
Dilation is the increase or decrease in the size of an figure or object.
A dilation with a scale factor of 2 is applied to the three line segments shown to form P'Q', A'B', and M'N'.
Hence:
P'Q' = scale factor * PQ = 2 * 2 = 4 cm
A'B' = 2 * 1.5 = 3 cm
M'N' = 2 * MN = 2 * 3 = 6 cm
The value of the dilated line segments P'Q', A'B' and M'N' are 4 cm. 3 cm and 6 cm

What is the slope-intercept equation for this line?
Answer:
y=-2x-1
Step-by-step explanation: This is because of rise/run. This means rise, count up or down until you hit the line that is horizontal to where your line intersects a whole point. Then run, what you count horizontal matches with your rise count. This means we can count 2/1 and since it's going down it's negative. So the slope is -2 and the y-intercept is -1 because it intersects through the y-intercept -1.
Please help !!! What’s the answer to this??
No links please ! And no replies if you don’t know the answer.
Answer:
Average speed is distance/time. You could say, 12/6 = 2 miles per second and say that’s the answer, but we relate to mph so much better. Since there are 60 x 60 = 3600 sec in an hour, that same speed is:
2 x 3600 = 7,200 mph
No “car” can travel this fast. Some rocket cars have gone about 1/10th this speed.
How do I find the current price of a stock when the rate is not constant? Please give a formula step by step answer I'm so confused
Answer:
There is no affirmative formula, but this is the basics
Step-by-step explanation:
DDM Formula=
Stock value = Dividend per share / (Required Rate of Return – Dividend Growth Rate)
Rate of Return = (Dividend Payment / Stock Price) + Dividend Growth Rate.
The P/E Ratio. The price-to-earnings ratio or P/E ratio is a popular metric for valuing stocks that works even when they have no dividends. Regardless of dividends, a company with high earnings and a low price will have a low P/E ratio. Value investors see such stocks as undervalued.
The current price is the most recent selling price of a stock, currency, commodity, or precious metal that is traded on an exchange and is the most reliable indicator of that security's present value.
The formula consists of taking the DPS in the period by (Required Rate of Return – Expected Dividend Growth Rate). For example, the value per share in Year is calculated using the following equation: Value Per Share ($) = $5.15 DPS ÷ (8.0% Ke – 3.0% g) = $103.00.
Briefly, in order to be eligible for payment of stock dividends, you must buy the stock (or already own it) at least two days before the date of record. That's one day before the ex-dividend date.
A bicycle costs $240 and it loses 3/5 of its value each year.
A. Write expressions for the value of the bicycle,in dollars, after 1,2, and 3 years
B. When will the bike be worth less than $1?
Answer:
A. $96.00, $38.40, $15.36
B. after 6 years
Step-by-step explanation:
An exponential function has the general form ...
y = (initial value) × (growth factor)^t
__
A.The growth factor is 1 more than the growth rate. Here, the "growth" is actually a decay at the rate of 60% per year, so the growth rate is -0.60. The initial value is $240. The value equation can be written ...
y = 240(1 -0.60)^t
We want the value after t=1, t=2, and t=3 years.
y = $240(0.4)^1 = $96 . . . value after 1 year
y = $240(0.4)^2 = $38.40 . . . value after 2 years
y = $240(0.4)^3 = $15.36 . . . value after 3 years
__
B.We want to find t when y < 1.
240(0.4)^t < 1
0.4^t < 1/240 . . . . . . . . . . . . divide by 240
t × log(0.4) < log(1/240) . . . take logs
t > log(1/240)/log(0.4) . . . . . . . inequality reverses because log(0.4) < 0
t > 5.98
The bike will be worth less than $1 after about 6 years.

Answer:
Maurico started with more :)
Step-by-step explanation:
Mariah started with 150 while Maurico started with around 190 so he has more to start with :)
Have a great day!
Please rate and mark brainliest!
Answer:
Mauricio
Step-by-step explanation:
To find who started with more money in their savings account, we want to observe the savings in $ when time=0 years
So by looking at the table of Mariah's savings, we see that when t=0 she had S=150$
By looking at the graph which describes Muaricio's savings as a function of time, we can see that when time=0 or x=0, y=S=190$
In other words, the y-intercept is the initial amount of savings.
190>150
:P
Hope this helps, it would be appreciated if you made me brainliest.

Proportional ratios : If I mow 75 % of 150 square meters of my grass, how much did I mow?
Answer:
You mowed 112.5 square meters of your grass.
Step-by-step explanation:
First, convert the percentage to a fraction.
75% = 3/4
Then to find 75% of 150, multiply 3/4 and 150.
(3/4) * 150
(3*150)/4
450/4
112.5
We can now say that 75% of 150 is 112.5, meaning you mowed 112.5 square meters of your grass.
Answer:
[tex]\huge\boxed{\sf 112.5 \ m^2\\}[/tex]
Step-by-step explanation:
Grass mowed:
= 75% of 150 m²
[Key: "of" means "to multiply" and "%" means "out of 100"]
[tex]\displaystyle = \frac{75}{100 } \times 150\\\\= \frac{75 \times 15}{10} \\\\= \frac{1125}{10} \\\\= 112.5 \ m^2\\\\\rule[225]{225}{2}[/tex]

The length of a rectangle is 12 feet more than twice the width. If the area is 320 square feet, what is the length? What is the width?
Answer:
Length of rectangle is 32 feet and width is 10 feetStep-by-step explanation:
Given,
The length of a rectangle is 12 feet more than twice the width and area is 320 square feetLet's assume, width of rectangle x feet and length of the Rectangle be 12 + 2x respectively. To Calculate the length and width of rectangle we'll use the formula of area of rectangle:
[tex] \\ \star \: { \underline{ \boxed { \pmb{ \sf{ \purple{Area _{(rectangle)}= Length \times width}}}}}} \\ \\ [/tex]
Substituting the required values:
[tex]\dashrightarrow \sf \: \: \: \: (12 +2x) (x) = 320 \\ [/tex]
[tex]\dashrightarrow \sf \: \: \: \: 12x + 2x^2 = 320 \\ [/tex]
[tex]\dashrightarrow \sf \: \: \: \: 12x + 2x^2- 320 = 0 \\ [/tex]
[tex]\dashrightarrow \sf \: \: \: \: 2x^2 + 12 - 320 = 0 \\ [/tex]
[tex]\dashrightarrow \sf \: \: \: \: 2(x^2 + 6x - 160) = 0 \\ [/tex]
[tex] \dashrightarrow \sf \: \: \: \: 2(x^2 + 16x - 10x - 160) = 0 \\ [/tex]
[tex]\dashrightarrow \sf \: \: \: \: 2(x - 10)(x + 16) = 0 \\ [/tex]
[tex]\dashrightarrow \: \: \: \: \underline{ \boxed{ \purple{ \pmb{ \rm{ x = 10 \: or \: -16}}}}} \\ [/tex]
Hence,
Width of rectangle = x = 10 feet Length of rectangle = 12 + 2x = 12 + 2(10) = 32 feet[tex]~[/tex]
[tex] \underline{\therefore{ \pmb { \frak{Length \: and \: width \: of \: rectangle \: is \: 32 \: and \: 10 \:ft}}}}[/tex]

If VZ=p–7 and WY=p–21, what is the value of p?
Answer:
p = 35
Step-by-step explanation:
the midsegment WY is half the measure of VZ , that is
WY = [tex]\frac{1}{2}[/tex] VZ ( substitute values )
p - 21 = [tex]\frac{1}{2}[/tex] (p - 7) ← multiply through by 2 to clear the fraction
2p - 42 = p - 7 ( subtract p from both sides )
p - 42 = - 7 ( add 42 to both sides )
p = 35
