Due to a lack of context, I’m guessing you want the equation of this line. If you go back to the equation y = mx + b, m represents SLOPE, and b represents the y-int (0, b).
As the slope is -2 and the y intercept is (0,0), the line’s equation would be y = -2x + 0, or simply y = -2x.
The answer is D) 30.
You divide 40 by 24 since those sides are similar, and you should get about 1.666. You multiply that by 18 to get the missing side length, which is 30.
Answer:
Perimeter = 31.4in
Area = 78.5in^2
Step-by-step explanation:
Perimeter -
2 x 5 x 3.14 = 10 x 3.14 = 31.4in
Area -
5 x 5 x 3.14 = 25 x 3.14 = 78.5in^2
75 percent is 12 which is 3/4 so make a proportion .75/12 = 1/x cross multiiply and you get 16
Answer:
This equation is in standard form: ax 1+bx+c=0. Substitute 9 for a, 16 for b, and −112 for c in the quadratic formula 2a−b±b2−4ac.x= 2×9−16± 16^2−4×9(−112)Square 16.x=2×9−16±256−4×9(−112) Multiply −4 times 9.x=2×9−16± 256−36(−112) Multiply −36 times −112.x=2×9−16±256+4032 Add 256 to 4032.x=2×9−16±4288 Take the square root of 4288.x=2×9−16±8+67 Multiply 2 times 9x=18−16±8=67
