Answer: $24, $36, $44, $59, $66, $71, $108
Step-by-step explanation:
The y intercept is 9 and the unit rate is -7
So we plug these numbers in
y= -7x (the unit rate)+ 9 (y intercept)
y= -7x+9
So remember that the distance formula is
.
1.

Distance between (4,-5) and (4,-2) is 3 units.
2.

Distance between (1,1) and (-1,4) is √13 (or 3.61 rounded to the hundreths) units.
5÷(4-3)×9-2
= 5÷1×9-2
= 5 × 9 - 2
= 43
You must solve the bracket first.After that,solve the multiplication and division,followed by addition and substraction if any.That's the theory to solve the right step
For the second question the answer should be 50×6=300+50=350 letters for Matilda. And for Lorraine It would be 40×6=240+80=320
