Answer:
A and D are equal
Step-by-step explanation:
Given
Required
The equal matrices
First, we simplify the given expressions
Open bracket
Next:
Divide by 3
Lastly:
By comparison:
Answer: y = (1/4)x - 1
Slope intercept form is . The -intercept is -1 so we have . To find , look at the points and . The line goes up 1 and over 4, so the slope, , equals . Thus the full equation is
.
a.) All real numbers x greater than 2
===> X > 2
b.) 6 more than a number k is less than or equal to 12
===> 6+k =< 12
the ratio will be 132 to 89
6 1/8 ×10 2/7= 60
60÷2 1/3= 30
The answer:
30
