Slope is rise over run. This means your y is over your x. Start with subtracting your y values. It doesn't matter which way, just make sure you do the same with the x values. For this, I'll do it 6 - -9. The two negatives cancel out and make a positive, so your y value is 15. Now, do the same to the x values. -9 - -1 is -8. You're left with 15/-8. Since this can't be simplified, this is your final answer. Hope I helped!
Answer:
see below
Step-by-step explanation:
-2x-5y=30
To find the x intercept, set y =0 and solve for x
-2x-5*0=30
-2x = 30
Divide each side by -2
-2x/-2 = 30/-2
x =-15
To find the y intercept, set x =0 and solve for y
-2*0-5y=30
-5y = 30
Divide each side by -5
-5y/-5 = 30/-5
y = -6
140*.20=28
140-28= $112
so, the current price is $112
Answer:
Because multiplying by 0.10 is the same as dividing by 10. It is a decimal smaller than 1 its the same thing as multiplying something by a fraction because when you multiply a number by a fraction the number gets smaller.
So multiplying by 10 and multiplying by 0.10 are inverses of each other.
