Answer:
The third graph is correct for the inequality 2x + 3y > -3
Step-by-step explanation:
The slope of the graph is –2/3.
The y-intercept is –1
The area above the dashed be line is shaded.
To verify, choose a coordinate in the shaded area, substitute the values for x and y. Calculate and check.
For example: (1,1)
2(1) + 3(1) > –3
2 + 3 > –3
5 > –3 True.
It’s is greater it would only be equal if you multiplied it by 100
Answer: Choice ARaising something to the 1/4th power is the same as applying the 4th root to that expression. Raising an expression to the 1/n power is the same as applying the nth root.
Rule:
(if the text is too small it basically says x to the (1/n) = square root with a small 'n' all over x)
Answer:
275
Step-by-step explanation:
You just have to add them together.
We are given the two sides of the right triangle therefore we can use the pythagorean theorem to solve for the third side. This theorem states that, in a right triangle the square of the hypotenuse is equal to the sum of the square of each leg.
c² = a² + b²
70² = 35² + b²
b = √70² - 35²
b = 60.62 feet
