Start by converting your two equations into slope-intercept form. 

3x - 3y = -9 
-3y = -3x -9 Subtract 3x from both sides
y = x +3 Divide both sides by -3

2x + y = 9
y = -2x + 9 Subtract 2x from both sides. 

Then graph both lines (in which case the point where they intersect is the solution) or substitute in each point until both equations are true. 

In this case the solution is (2,5); both equations become 5=5 when you substitute in the point's coordinates.

Edwin needs to buy a car, a truck, and a motorcycle for his shipping business. He wants the car to be red or yellow; the truck t
Amanda [17]
We can solve problems like this using multiplication rules. Since the order of colors and combinations does not matter, we can multiply all  values in any order we so choose. In this case, our values are colors and vehicles:

Car: Red, Yellow
Truck: Black, White, Silver
Motorcycle: Green, Blue, Orange

We have 2 options with a car, 3 options with a truck, and 3 options with a motorcycle. Since he wants one of each, we will multiply all of the color options together: 

2 x 3 x 3

= 18

Edwin has 18 different combination of vehicles to choose from.

Why can you use cross products to solve the proportion StartFraction 18 over 5 EndFraction = StartFraction x over 100 EndFractio
gtnhenbr [62]

Answer:

  it is application of the multiplication property of equality

Step-by-step explanation:

You can use "cross products" to solve any proportion. What looks like a "cross product" is just application of the multiplication property of equality. That property says the variable value is unchanged if both sides of the equation are multiplied by the same value.

For your fraction, the "cross product" is what you get when you multiply both sides of the equation by 500.

  \dfrac{18}{5}=\dfrac{x}{100}\qquad\text{given}\\\\\dfrac{18\cdot5\cdot100}{5}=\dfrac{x\cdot5\cdot100}{100}\qquad\text{multiply by $5\cdot100$}\\\\18\cdot100=5\cdot x\qquad\text{cancel common factors; looks like cross product}

__

Note that the next step here is to divide by the x-coefficient, the 5 that was in the left-side denominator.

  \dfrac{18\cdot100}{5}=x\qquad\text{divide by 5}

Please also note that this is exactly the same result you would get by multiplying the original equation by the original denominator of x.

Write an equation that could be used to find the measure of angle A
Ainat [17]

Answer: C

Step-by-step explanation: The numerator is the angle measure, and the denominator is the side length. For angle B, the angle is 47 degrees. The opposite side is b, which is 85. We are finding the angle A, which is the numerator. The side 94 is opposite of angle A.
