Step-by-step explanation:
his father's age= 4x
his mother's age= 4x- 7
his age= x
x+4x+4x-7=101
x+ 4x+ 4x= 101+ 7
9x= 108
=
x= 12
Tesfa is 12 years old
Answer: 5
Step-by-step explanation:
16x+12x+8=148
16x+12x=148-8
28x=140
X=140/28
X=5
Answer:
x= 13; B= 119
Step-by-step explanation:
9x+2= 180-(5x-4)
=> x= 13
=> B= 9 x 13 + 2= 119
Answer: The last vertices should be D (2,6)
Step-by-step explanation:
The required table for the given values of x and y is:
<em>x | y</em>
<em>0 -2</em>
<em>1 -2</em>
<em>2 0</em>
<h3>Table of values of functions</h3>
Tables of values are tables that interpret values into function or otherwise.
Given the function y=x²-x-2
We can vary the values of x to create a table
When x = 0
y=0²-0-2
y = -2
When x = 1
y=1²-1-2
y = -2
When x = 2
y=2²-2-2
y = 0
The required table for the given values of x and y is:
<em>x | y</em>
<em>0 -2</em>
<em>1 -2</em>
<em>2 0</em>
