Answer:

(0, -3) and (2, 1)

Step-by-step explanation:

There are 5 points marked on the graph: (±2, 1), (±1, -2) and (0, -3). These are solutions to the equation describing the function:

... y = x² - 3

Apparently, you are being asked to report the coordinates of any two of these points.

Comment on the problem

The wording "solutions to the function" is a bit odd. An equation has solutions—values of the variables that make it be true. A function is a relationship between values, a definition. There is nothing to solve.

In the above we have assumed the intent is to find (x, y) pairs that match the function definition. Sometimes, we're interested in values of x that make y be zero. (x, y) = (±√3, 0) It isn't obvious what the intent of this question is.

What is 4|2y-3|-1=11

umka2103 [35]

implifying 4[2y + -3] + -1 = 11 Reorder the terms: 4[-3 + 2y] + -1 = 11 [-3 * 4 + 2y * 4] + -1 = 11 [-12 + 8y] + -1 = 11 Reorder the terms: -12 + -1 + 8y = 11 Combine like terms: -12 + -1 = -13 -13 + 8y = 11 Solving -13 + 8y = 11 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '13' to each side of the equation. -13 + 13 + 8y = 11 + 13 Combine like terms: -13 + 13 = 0 0 + 8y = 11 + 13 8y = 11 + 13 Combine like terms: 11 + 13 = 24 8y = 24 Divide each side by '8'. y = 3 Simplifying y = 3

Tom is afraid of heights above 9 feet. He is asked to repair a side of a high deck. The bottom of a ladder must be placed 6 feet

Viktor [21]

Use pathagoream theorem. You get the equation: 10^2=6^2+x^2 then solve and simplify to get x=8 So no Tom is not afraid of the heights
