In the second to last step, you end up with -x ≤ 13, but x can't be negative, so the sign is flipped, turning x positive and 13 negative, leaving us with x ≥ -13, which is why the line goes right.

-16x-10>14-10x hi can u please help me with this

x < -4

Equality Properties

Step-by-step explanation:

Step 1: Define inequality

-16x - 10 > 14 - 10x

Step 2: Solve for x

Add 16x to both sides: -10 > 14 + 6x
Subtract 14 on both sides: -24 > 6x
Divide 6 on both sides: -4 > x
Rewrite: x < -4

Here we see that any value x that is less than -4 would work as a solution.

The vertex angle of an isosceles triangle measures 42°. A base angle in the triangle has a measure given by (2x + 3)°. What is t

larisa [96]

An isosceles triangle is one in which 2 angles have similar measure while the other one is different. In this case, the 2 vertex angles have a measure of 42 degrees, therefore the third angle which is equal to (2x + 3) is:

(2x + 3) + 42 + 42 = 180

2x + 3 = 96

x = 46.5°

If, in 7 years, Susan will be 2 times as old as she was 3 years ago, what is Susan’s present age?

pochemuha

Answer:

Step-by-step explanation:

Set Susan's present age as x, her age from 3 years ago as x-3, and her age in three years as 2(x-3)

Since her age in seven years = 2 times as old as she way 3 years ago, set up the equation:

x+7 = 2(x-3)

x+7 = 2x-6

x = 13
