Y = -1/2x + 4....sub in -1/2x + 4 in for y in the other equation
x + 2y = -8
x + 2(-1/2x + 4) = -8
x - x + 8 = -8
x - x = -8 -8
0 = -16...incorrect....NO SOLUTIONS
Slope between the points (x1,y1) and (x2,y2) is
(y1-y2)/(x1-x2)
given
(8,10) and (1,5)
(x,y)
x1=8
y1=10
x2=1
y2=5
slope=(10-5)/(8-1)=5/7
slope=5/7
Answer:
20.8 ft²
Step-by-step explanation:
area = (ab sin C)/2
area = (6 ft × 8 ft × sin 60°)/2
area = 20.8 ft²
Answer: (D) <em>bottom right graph</em>
<u>Step-by-step explanation:</u>
The vertex form of a quadratic equation is: f(x) = a(x - h)² + k, where
- (h, k) is the vertex
- |a| is the vertical stretch
- sign of "a" determines the direction of the parabola
Given g(x) = (x - 3)² - 5
- vertex (h, k) = (3, -5)
- vertical stretch |a| = 1
- sign of "a" is positive so parabola points up
The only graph that satisfies all of these conditions is the bottom right.
