<span>a. 2x + 11y when x = 4 and y = 2 is 2(4) + 11(2) = 8 + 22 = 30
</span><span>b. 4(y + 1) when y = 7 is 4(7 + 1) = 4(8) = 32
</span><span>c. 3x when x = 12 is 3(12) = 36
</span><span>d. x + 8y when x = 8 and y = 3 is 8 + 8(3) = 8 + 24 = 32
Options a and d have a value of 32. </span>
Distance = Speed x time = 162 x 3 = 486 miles/hour
Answer: 486 miles/hour
Answer:
C
Step-by-step explanation:
to find the slope m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 6, - 24) and (x₂, y₂ ) = (4, 11) ← 2 points from the table
m = = = → C
