It would be 12 because it's twice it's number so it's multiplying and is less than 20.
To make your equation easier to graph, you can try simplifying it. Add 6 to both sides.
y-6 = (x+2)
+ 6 + 6
y = x + 8
Then, try plugging in values for x and using that output as your y value. Some coordinates on your graph would be (0, 8), (1, 9), (2, 10), (3, 11), etc.
Hope this helps!
Answer:
<u>x = ±2</u>
Step-by-step explanation:
Given :
<u>y = 64 - 16x²</u>
<u />
=========================================================
Add 16x² to each side (take y = 0) :
⇒ 0 + 16x² = 64 - 16x² + 16x²
⇒ 16x² = 64
=========================================================
Divide both sides by 16 :
⇒ 1/16 × 16x² = 1/16 × 64
⇒ x² = 4
=========================================================
Taking square root on both sides :
⇒ √(x²) = √4
⇒ <u>x = ±2</u>

Step-by-step explanation:
Answer:
9.7303888 miles
Step-by-step explanation:
Given the following :
Set target = 12 miles per week.
Miles ran on Monday = 4 3/4 miles
Miles ran on Wednesday = 3 1/3 miles
Miles ran on Friday = 1 11/17 miles
Number of miles covered for the week:
(miles covered on Monday + miles covered on Wednesday + miles covered on Friday)
= (4 3/4 + 3 1/3 + 1 11/17) miles
= (19/4 + 10/3 + 28/17) miles
= (4.75 + 3.33333 + 1.6470588) miles
= 9.7303888 miles
