Answer:
3
Step-by-step explanation:
Negative exponents mean that you flip the number upside down
so -7^-2 would become 1/-7^2
-7^2 would be 49
so the answer is <em>1/49</em>

Answer:
y = 8x + 2
Step-by-step explanation:
Slope-intercept form: y = mx + b
m = slope
b = y-intercept value
Evaluate: 2(1/4) + 2/5 ÷ (-1/2) - 1/4
⇛9/4 + 2/5 ÷ (-1/2) - 1/4
Take the LCM of the 4 and 5 is 20.
Again, 2 and 4 is 4.
⇛[(54+8)/20] ÷ [(-2 - 1)/4]
⇛62/20 ÷ (-3/4)
⇛62/20 × 4/-3
⇛62/{5*(-3)}
⇛62/-15.
