Step-by-step explanation:
Answer:
y=-2x+3
Step-by-step explanation:
Slope intercept form is y = mx + b where m is the slope, b is the y-intercept, and y and x are their respective coordinates.
The questions gives us a coordinate pair and a slope so all we need to find is the y-intercept to find the equation.
Begin by plugging in what we know.
(3) = (-2)(0) + b
3 = 0 + b
3 = b
Plug in the y-intercept (b) and slope (m)
y=-2x+3
Area: 20 x 30 so 600
perimeter: 20 + 20 + 30 + 30 = 100
Answer:
0.23 = 7/30
0.4 = 4/9
1.6 = 5/3
3.5 = 32/9
Step-by-step explanation:
I'm 100% that this is correct
9x²- 25
3x(3x) = 9x²
3x(5) = 15x
-5(3x) = -15x
-5(5) = -25
9x² + 15x - 15x - 25
9x² - 25 is your answer
hope this helps
