This can be expressed using the general formula for a² – b².
Sample Answer: No, Ingrid's statement is incorrect. In this situation, the starting point is at 170 feet, which denotes the y-intercept. The reduction of 4 feet per year symbolizes the rate of change, or slope. In the slope-intercept equation format, y = mx + b, with 'm' denoting the slope and 'b' signifying the y-intercept, the accurate equation would be y = −4x + 170.
Answer:
2.1 miles
Step-by-step explanation:
Refer to the attached illustration (you need to include all the mentioned locations and the distances between them),
enabling us to create a right triangle between the school and the hospital with side measures of: 1.7 and 1.2 miles
and the green line represents the direct path from the school to the hospital; thus, applying the Pythagorean theorem will yield the result:

When rounded to the nearest tenth:
2.1 miles
I think the right answer is D. 8x+8;
This is because Frank possesses X stamps while Chris has 8 plus 7 times the number of stamps Frank holds, making the total 8 + 7x (which is 7 times Frank's amount), so when you add Frank's stamps (x) to 8 + 7x, it results in 8 + 8x.
