5x-3 =2x+15 Someone pls help for geometry
1 answer:
Answer:
x = 6
Step-by-step explanation:
5x-3 = 2x+15
<h3>i) move 2x to the left-hand side and change its sign</h3>5x-2x-3 = 15
<h3>ii) move -3 to the right-hand side and change its sign</h3>5x-2x = 15+3
<h3>iii) collect like terms</h3>3x = 15+3
<h3>iv) add the numbers</h3>3x = 18
<h3>v) divide both sides of the equation by 3</h3>You might be interested in
The rate of change of the linear function represented by the table is 3
<h3>Rate of change of a function</h3>The rate of change of a function is also known as the slope of a function. The equation for calculating the slope is expressed as:
Slope = y2-y1/x2-x1
using the coordinates from the table (-2, -13) and (-1, -10)
Substitute
Slope = -10-(-13)/-1-(-2)
Slope = -10+13/-1+2
Slope =3
Hence the rate of change of the linear function represented by the table is 3
