Answer:
x = -1 ; y = 1
Step-by-step explanation:
x = -1
y = 1
Plug in the corresponding numbers to the corresponding variables:
y < -x + 1
(1) < -(-1) + 1
1 < 1 + 1
1 < 2 (True)
y > x
1 > -1 (True).

Area=length x width
A=10x(3/2 x + 1/2 y).
Now Distribute...
A=30x^2/2 + 10xy/2)
Now simplify fractions...
A=15x^2 + 5xy= 125
So I believe your answer is D)
Answer:
and 
Step-by-step explanation:
We have been given the parabola with vertex (1, -9) and y intercept at (0, -6).
Now we need to find the x-intercepts of that parabola. So first we begin by finding the equation of parabola using vertex formula:
Vertex for this formula is given by (h,k)
Compare that with given vertex (1,-9), we get: h=1, k=-9
So plug these into vertex formula:
...(i)
Plug given point (0, -6). into (i)
Plug a=3 into (i)
Now to find x-intercept, we just plug y=0 and solve for x

Answer:
Slope, Angle, & Distance:
Slope: 0.5625
The slope of the line connecting (15, 20) and (-1, 11) is 0.5625
Slope (m): 0.5625
Angle (θ): 29.3578°
Distance: 18.3576
Δx: 16
Δy: 9
Slope Intercept Form:
(y = mx + b)
y = 0.5625x + 11.5625
Step-by-step explanation:
Steps to Find Slope
Start with the slope formula
m=
(y2 - y1)
(x2 - x1)
Substitute point values in the formula
m=
(11 - 20)
(-1 - 15)
Simplify each side of the equation
m=
(11 - 20)
(-1 - 15)
=
-9
-16
Solve for slope (m)
m=0.5625
