Answer: D
Step-by-step explanation:
If segment D moves downward it means its function has a negative slope so the line will be decreasing.
Answer:
2x - 0.4x ;
8x/5 ;
Yes
Step-by-step explanation:
Let number of miles = x
Arlene:
Double number of miles = 2 * x = 2x
Subtract 20% of the result :
2x - 20% of 2x ;
2x - 0.4x
Raul:
Divides Number of miles by 5 ; x / 5
Multiplies result by 8 ;
8 * (x/5) = 8x /5
To know if expressions are equivalent :
Let x = 10 miles
Using Arlene's expression:
2x - 0.4x
x = 10
2(10) - 0.4(10) = 16
Using Raul's expression :
8x / 5
(8*10) / 5
80/5
= 16
Since they give the same result, we can conclude that the expression are equivalent
The answer you are looking for is 2 4/5. Hope this helps.
<span>So, x+15 + 2x = 90 </span><span>
<span>Therefore 3x = 90 - 15 = 75 </span>
<span>and so x=25. </span>
<span>So the smaller angles are x+15 = 40 degrees and
2x=50 degrees. </span>
<span>So the larger one is 50 degrees.</span></span>
Answer:
Step-by-step explanation:
point-slope form: y-y₁=m(x-x₁)
x₁= -5
y₁= 3
m= 5
y-3=5(x+5)
