Answer:
Growth: 3
y-intercept: 5
Step-by-step explanation:
1. Find the equation in slope-intercept form:
-6x+2y=10
2y=6x+10
y=3x+5
2. Then we can easily identify the growth and y-intercept.
Growth: 3
y-intercept: 5
4(x - 5) = 3x + 7
4x - 20 = 3x + 7
x - 20 = 7
x = 27
Hence there is only one solution. These types of equations are called linear equations and linear equations have a degree of 1, which means they have only one solution.
To help answer your question, a quadratic equation (an equation of degree 2) has 2 solutions, 1 solution, or no solutions (imaginary solutions).
I hope this helps ya.
Answer:
it equal 315%
Step-by-step explanation:
Rectangle=21 times 14=294 cm^2
Triangle=Base Times Height
Height=21-12=9cm
Area of triangle=16 times 9 =144
Area of both=294+144=438cm^2
Answer:
∠P = 39º
∠Q=120º
∠R = 21º
Step-by-step explanation:
m∠P+m∠Q+m∠R=180º (sum of ∠s in a triangle)
2x-3+6x-6+x=180º (substitution)
9x-9=180º (algebra)
9x=189º (algebra)
x=21º (algebra) (this is ∠R)
(2x-3)=39º (algebra) (this is ∠P)
6x-6=120º (algebra) (this is ∠Q)
