I got x=11

solution process: x-30=14-3x

-30=14-4x
-44=-4x
44=4x
11=x

Ex 1: The sum of two numbers is 93 and their difference is 41.<br> Find them.
musickatia [10]
Let x = the larger number
Let y = the smaller number
x + y = 93
x - y = 19 Add the two equations together.
2x = 112 Divide both sides of the equation by 2.
x = 56
56 + y = 93 Subtract 56 from both sides of the equations.
y = 37

What is the area of the triangle in the coordinate plane?
katovenus [111]
To solve for the area of a triangle you use the formula A=b*h/2. The base for this triangle is 4 and the height is 8. Take 4*8 which is 32 and divide that answer in half to get 16 which is your answer.

Olivia is making model cars to go on shelves in her room. The number of wheels she uses is a function of how many cars she makes
Luba_88 [7]

Answer:

Domain = 1 to 7

Range = 4 to 28

Step-by-step explanation:

Given that:

Number of wheels used is a function of number of cars manufactured.

Number of wheels present = 28

1 car uses 4 wheels

2 cars use 8 wheels.

3 car uses 12 wheels

and so on.

Let the function be of the form:

y =f(x)

Domain of the function is the value of x that can be given as valid input to the function.

Range of the function is the value of y that can be output of the function.

Let x be the number of cars manufactured.

Then value of y is nothing but x times 4.

y=4x

We are given that maximum value of y can be 28.

28 = 4x\\\Rightarrow x =7

Therefore, maximum value of input can be 7.

Minimum number of wheels can be 4 to make a minimum of 1 car.

Therefore domain is 4 to 28 and range is 1 to 7.

Write a linear equation that passes through the point (2,-9) and has a slope of -5
Anna [14]

Answer:

  • y = -5x + 1

Step-by-step explanation:

<u>Given:</u>

  • The slope m = -5 and point (2, -9)

<u>Use point slope form:</u>

  • y - y₁ = m(x - x₁), where (x₁, y₁) is the given point

<u>So the equation is:</u>

  • y - (-9) = -5(x - 2)
  • y + 9 = -5x + 10
  • y = -5x + 1
