y=-2x+10
3y-x+5=0
Solve the system using substitution

Answers

Answer 1
The first equation is already solved for y. So we can plug that into the second equation.

3y - x + 5 = 0
3(-2x + 10) - x + 5 = 0

Distribute the 3
-6x + 30 - x + 5 = 0

Combine like terms
-6x - x + 30 + 5 = 0
-7x + 35 = 0

Subtract 35
-7x = -35

Divide by -7
x = 5

Plug x into either equation to solve for y
y = -2x + 10
y = -2(5) + 10
y = -10 + 10
y = 0

Answers

Answer: to the nearest tenth its -1.1

to the nearest hundredth its -1.14

to the nearest thousandth its -1.143

as a percentage its −114.28571428%

-1.1,-1.14,-1.143 is the simplest form of -1.14285714286 in nearest 1oth, 100th and 1000th respectively.

The digit in the smallest location is unaffected if it is less than 5 in number. Rounding down is the process of reducing a number to zero after a certain number of digits. The digit in the smallest location is added with +1 if it is bigger than or equal to 5.

-1.14285714286 is simplified by rounding off

1. It can be rounded to the nearest tenth as -1.1

2. It can be rounded to the nearest hundredth as -1.14

3.  It can be rounded to the nearest thousand as -1.143

Thus, -1.1,-1.14,-1.143 is the simplest form of -1.14285714286

The equation m=40g gives the distance in miles, m, that a car can travel using g gallons of gas.
B. Write an equation that represents the inverse function: the gallons of gas as a function of distance in miles.
Question: How can I write an equation that represents the Inverse function of this problem?

Answers

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the Concept of the function.

to get the inverse of the function,

let's consider that y is the function of m

hence, y = m

now, we know that m = 40g

hence, relatively, y = 40g

but to get inverse, we need gallon of gas as function of distance, hence

g = y/40,

since we know that y = m, replace it

hence the new inverse function is,

====> g = y/40

ABCD is a parallelogram.
AD = 12 cm.
DC = 9 cm.
The perpendicular distance of
from CD is 8 cm.
What is the perpendicular distance of AD from BC?

Answers

9514 1404 393

Answer:

  6 cm

Step-by-step explanation:

The area of the parallelogram is the same, either way you figure it.

  A = bh

  A = CD(length ⊥ to CD)

  A = (9 cm)(8 cm) = 72 cm²

__

  A = AD(length ⊥ AD)

  72 cm² = (12 cm)(length ⊥ AD)

  (length ⊥ AD) = (72 cm²)/(12 cm) = 6 cm

The perpendicular distance of AD from BC is 6 cm.
