Explanation:
For each lawn he mows = $5
<u>He should mow 6 lawns but did only 3 lawns as other 3 he forgot to mow.</u>
earned:
The value of b is -6.
The expression is
To determine the value of b, we shall solve the expression.
Applying exponent rule, , we get,
Applying exponent rule, , we have,
The expression is of the form, then
Applying this rule, we get,
Dividing both sides by 4, we have,
Hence, the value of b is -6.
Answer:
Step-by-step explanation:
Since we're looking at perpendicular lines, the slope of the new line is the reciprocal of the original line.
So the slope of our new line is
So far, we are looking at
Now we need to find the b value by plugging in the given point.
So the final equation is
Let her brother's age be x
Sarah is 2x + 4
