When you buy multiple stocks, you have to multiply your gains and losses by how many stocks you own. For example, if you own two stocks of Netflix, and the stock increases in value by $10, you have gained $20 (To calculate this you do $10 x 2).
Suppose you own 5 stocks of Netflix. If the value of Netflix stock increases by $30 after you buy it... how much money have you made?
The gas in Dads car holds 12 gallons. Athe gas tank in Moms truck holds 50% more than that. How much gas does the truck's tank hold? Explain why this situation can be represented by the equation. Make sure that you explain what t represents.
Answer:
18 gallons
Step-by-step explanation:
Step one:
given data
The gas in Dad's car holds 12 gallons
the gas tank in Moms truck holds 50% more than that in Dad's car
Hence 50% of 12 is
=50/100*12
=0.5*12
= 6 gallons
We are told that the gas tank in Moms truck holds 50% more than that in Dad's car
Therefore Mum's car will hold
=12+6
=18 gallons

Marla bought 1250 pounds of pecans at $1.29 per pound and another 1500 pounds of pecans at $1.59 per pound. She sold all the pecans for \$6.75 per kilogram. After paying her suppliers, how much money did she make?
Answer:
After paying her suppliers, she made $4,575.
Step-by-step explanation:
First, you have to multiply the number of pounds purchased for the price:
$1.29*1250=$1,612.5
$1.50*1500=$2,250
Now, you can add both amounts to find the total cost:
$1,612.5+$2,250=$3,862.5
Now, you have to find the total amount of lb purchased and determine the kg they represent given that 1 kg is equal to 2.20 lb:
1250+1500=2750
2.20 lb → 1 kg
2750 lb → x
x=(2750*1)/2.20= 1250 kg
Now, you can find the total amount sold by multiplying the price per kilogram for the amount of kg:
$6.75*1250=$8,437.5
Finally, you have to subtract the total cost from the total amount sold:
$8,437.5-$3,862.5=$4,575
According to this, the answer is that after paying her suppliers, she made $4,575.

Answer:
f(x) = 3x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 3)
m = [tex]\frac{3-0}{1-0}[/tex] = 3 , then
y = 3x ← is the equation of the graphed line
Sari opened a savings account with $150.00. The account earns interest at a rate of 6% compounded annually.
The table below shows her account balance at the end of each of the first three years.
If Sari makes no additional deposits or withdrawals, which of the following will be closest to her account balance at the end of year 6?
$184.65
$189.37
$200.73
$212.77
Step-by-step explanation:
A = P(1 + r)^t
= $150.00 * (1 + 0.06)^6
= $212.77.
Hence Sari will have $212.77 at the end of year 6.
Which table represents a linear function?
Answer:
the second one
Step-by-step explanation:
The table that represents a linear function is the first one, where the values of y are obtained by multiplying the corresponding values of x by a constant factor of 5.
The first table:
x: 1,2,3,4,5
y: 5,20,45,80,125
In this table, the values of y are obtained by multiplying the corresponding values of x by a constant factor of 5.
The relationship between x and y is consistent and can be expressed by the equation y = 5x, which is a linear function.
The second table:
x: 1,2,3,4,5
y: 5,25,125,625,3125
In this table, the values of y are obtained by raising the corresponding values of x to increasing powers of 5.
The relationship between x and y is not consistent and cannot be expressed by a linear function.

FAST ILL MARK U BRAINLIEST Write an equation of the line that passes through (2, −1) and is parallel to the line 2y + 3x = 8 . Write your answer in slope intercept form.
Answer:
y=[tex]-\frac{3}{2}[/tex]+2
Step-by-step explanation:
for an equation to be parallel with another both should have the same rate of change(m).
the line given to us is in general form, and we can change it to slope-intercept form to get the slope. (y=mx+b)
Isolate for y:
2y+3x=8
2y=-3x+8
y=-3/2x+8/2
y=-3/2x+4
thus the slope of the line we are trying to find must also equal -3/2
use point slope form to find the equation (substitute (2, -1) into equation)
y-y1=m(x-x1)
y-(-1)=(-3/2)(x-2)
y+1=[tex]-\frac{3}{2}[/tex]x+3
y=[tex]-\frac{3}{2}[/tex]+2
