Answer:
The rate of change is the slope
In this case
m=2d+50 is a slope intercept equation.
where m is where the y would be
the 2 which is originally where the slope or (m) would be
the d for the (x)
and 50 for the y intercpet or (b)
so
#1=2
The expalantion is the same but different numbers, when asked for the rate of change look at the slope or the number next to the variable. Also put it in y=mx+b form to make sure the number is correct.
#2= -6
Answer:
yes; 4² + 3² = 5²
Step-by-step explanation:
Pythagorean theorem.
In a right triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides. Hypotenuse is the longest side of the triangle.
4² + 3² = 5²
16 + 9 = 25
25 = 25
Answer: 
Step-by-step explanation:
Add 2 to both sides of the equation and divide both sides of the equation by 15. Then:
Apply base 8 to both sides of the equation:
Solve for "x", then you get:
![-2x-7=8^{\frac{1}{3}}\\\\-2x=\sqrt[3]{8}+7\\\\ x=\frac{\sqrt[3]{8}+7}{-2}\\\\x=-4.5](https://tex.z-dn.net/?f=-2x-7%3D8%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C-2x%3D%5Csqrt%5B3%5D%7B8%7D%2B7%5C%5C%5C%5C%20x%3D%5Cfrac%7B%5Csqrt%5B3%5D%7B8%7D%2B7%7D%7B-2%7D%5C%5C%5C%5Cx%3D-4.5)
Answer:
5√3 / 2
Step-by-step explanation:
tan 30 = ( 5 / 2 ) / y
1 / √3 = 5 / 2y
2y = 5√3
y = 5√3 / 2
