Answer:
The solution to the system of equations is:
[tex]x=10,\:y=4[/tex]
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}5x-4y=34\\ -x+8y=22\end{bmatrix}[/tex]
Multiply -x+8y=22 by 5: -5x+40y=110
[tex]\begin{bmatrix}5x-4y=34\\ -5x+40y=110\end{bmatrix}[/tex]
so adding the equations
[tex]-5x+40y=110[/tex]
[tex]+[/tex]
[tex]\underline{5x-4y=34}[/tex]
[tex]36y=144[/tex]
solve 36y = 144 for y:
[tex]36y=144[/tex]
divide both sides by 36
[tex]\frac{36y}{36}=\frac{144}{36}[/tex]
Simplify
[tex]y=4[/tex]
For 5x-4y=34 plug in y=4
[tex]5x-4\cdot \:4=34[/tex]
[tex]5x-16=34[/tex]
Add 16 to both sides
[tex]5x-16+16=34+16[/tex]
Simplify
[tex]5x=50[/tex]
Divide both sides by 5
[tex]\frac{5x}{5}=\frac{50}{5}[/tex]
Simplify
[tex]x=10[/tex]
Therefore, the solution to the system of equations is:
[tex]x=10,\:y=4[/tex]

Step-by-step explanation:
f(x)=(x+10)
g(x)=-x²-2x-4
f(x)*g(x)=(x+10)(-x²-2x-4)
x(-x²)+x(-2x)+x(-4)+10(-x²)+10(-2x)+10(-4)

Soos is spending money at an average rate of $5 per day. After 9 days, he has $25 left.
How much money did Soos have at the beginning (on day 0)?
y - 5= 9(x - 25)
Answers
Answer:
$70
Step-by-step explanation:
According to the problem, calculation of given data are as follows:
Spending money at rate = $5 per day
After 9 days money left = $25
We can calculate the money on day 0 by using following formula,
y = mx + b
Here, y = money left after 9 days
m = rate of spending money
x = number of days
b = money on day 0
So, by putting value, we get
$25 = (-5 × 9 ) + b
b = $25 + $45
= $70

A hot air balloon holds 2,200 cubic meters of helium. The density of helium is 0.1785 kilograms per cubic meter. How many kilograms of helium does the balloon contain, rounded to the nearest tenth of a kilogram?
Answers
Answer:
392.7
To get the answer multiply Density * Volume
Mass = 0.1785 * 2200
Mass = 392.7
The mass of the helium with a density of 0.1785 kilograms per cubic meter and volume of 2,200 cubic meters is 392.7 kg
What is density?
The density of a substance is its mass per unit volume. It can be represented mathematically as follows:
density = mass / volume
Therefore,
mass of the helium = ?
density of the helium = 0.1785 kilograms per cubic meter
volume of helium = 2,200 cubic meters
Therefore,
mass = density × volume
mass = 0.1785 × 2200
mass = 392.7 kg
