<span>First we have to find the slopes, we need it in the slope intercept form for this:
2x - 3y = -5; this is the standard form
-3y = -2x - 5
Get rid of all those negatives, multiply eq by -1
3y = 2x + 5
Divide by 3 to get y
y = x +
The slope of this equation (m1) is </span>
First, factor the polynomial. Then, set each binary answer to zero and solve. Those are the values of x where the graph either crosses or touches the graph.
x²-9x+20
(x-5)(x-4)
x-5=0 | x=5
x-4=0 | x=4
The zeros are 4 and 5
Answer:
x = 40
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
126° is an exterior angle of the triangle, then
x + 2x + 6 = 126
3x + 6 = 126 ( subtract 6 from both sides )
3x = 120 ( divide both sides by 3 )
x = 40
Answer:
6x-8
Step-by-step explanation:
2x-4+4(x-1)
2x-4+4x-4
6x-4-4
6x-8
Answer:
112.5ft^2
Step-by-step explanation:
10 x 9 = 90
9 × 5 × .5 = 22.5
90 + 22.5 = 112.5
