I need to know if the following questions are true or false

Triss [41]

Answer:

False

Step-by-step explanation:

To find <A, we can do 5x - 80 = 3x + 20.

As we simplify, we will get 2x = 100, which is x = 50

Therefore, <A will be 50 degrees and not 45 degrees.

Also, if you need y, you can do:

3y - 7 = y + 7

2y = 14

y = 7

In the graph above, the coordinates of the vertices of quadrilateral QPRS are Q(2, 4), P(4, 4), R(3, 1), and S(1, 1). If quadril

larisa [96]

Answer:

(1, -1)

Step-by-step explanation:

When you reflect a point (x, y) across the x-axis, its coordinates

become (x, -y).

Thus, when you reflect point S to Point J, the coordinates change from (1, 1) to (1, -1).

Multiply and solve for x: x(x + 12) – 8x = 14 + x(x – 4)

erik [133]

Using the distribution method:

x^2 + 12x - 8x = 14 + x^2 - 4x

x^2 + 4x = x^2 - 4x + 14

Now, I'm isolating x by moving all the x's onto one side of the equation:

x^2 - x^2 + 4x + 4x = 14

Combine like terms (x^2 cancels out):

8x = 14

x = 14/8

Simplified: x = 7/4

2.<br> If y = V9 – 3x, determine the value of x for which y will be a real number.

Pepsi [2]

Answer:

x ≤ 3

Step-by-step explanation:

The expression inside the radical ≥ 0, thus

solve

9 - 3x ≥ 0 ( subtract 9 from both sides )

- 3x ≥ - 9

Divide both sides by - 3, reversing the symol as a result of dividing by a negative quantity

x ≤ 3

Any value of x less than or equal to 3 ensures $\sqrt{9-3x}$ is real
