Answer:

Infinitely many solutions: -5x+9y=2

One solution: -10x+5y=4

No solution: -10x+18y=5

Step-by-step explanation:

 Solve for y from each equation to obtain the equation of the line in slope-intercept form:

y=mx+b

m: slope

b: y-intercept

<u>EQUATION ON THE TOP:</u>

-10x+18y=4\\\\y=\frac{5}{9}x+\frac{2}{9}

Equation 1:

5y=10x+4\\\\y=2x+\frac{4}{5}

The equation on top and the equation equation 1 has different slopes and different y-intercept, therefore the system will have one solution.

Equation 2:

 9y=5x+2\\\\y=\frac{5}{9}x+\frac{2}{9}

The equation on top and the equation equation 2 are the same, therefore, the system will have infinitely many solutions.

Equation 3:

18y=10x+5\\\\y=\frac{5}{9}x+\frac{5}{18}

The slopes are equal, then both lines will be parallels, therefpre  the system will have no solution.

<h3>Answer:  300 square feet</h3>

Explanation:

The trapezoid has area of

A = h*(b1+b2)/2

A = 6*(10+18)/2

A = 84

The rectangle is 18 ft by 12 ft, which leads to an area of 18*12 = 216 sq ft.

Adding the two sub-areas gets us: 84+216 = 300

The total area of the house-shaped figure is 300 sq ft.

Im kinda confused ;-;​

Answer:

42-38

42 + (-38)

-38+42

Step-by-step explanation:

In all of these expressions, the 38 has to be negative because that is what you're taking away from the 48. When you have -(- it turns into a +.

In -42 + 38 the 42 is negative, but that is Emma's total amount so it's positive

With -42 -(-38) they did the just added those two together which would make the 42 still negative and the 38 positive.

THen with 42 + 38 the 38 is being subtracted from what she has so you would not add 38 to her total.
