Answer:
The radius of the circle is 3.5 inches.
Step-by-step explanation:
The radius is half the diameter:R= 1/2 d
Substitute the value of d (7 inches) in the formula to find r:
r= 1/2 x 7 in
r= 3.5 in
Answer is 2x-2

Answer:
Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
Step-by-step explanation:
4c + 6a ≤ 120:
You can set up the inequality 4c + 6a ≤ 120, because it takes 4 hours to build per child bike (c) and 6 hours to build an adult bike (a), all together this time cannot surpass 120 hours. That is why you use the 'less than or equal to' sign.
4c + 4a ≤ 100:
You can then set up the inequality 4c + 4a ≤ 100, because it takes 4 hours to test a child bike (c) and 4 hours to test an adult bike (a). Since 100 hours is the max amount of time they can use to test out bikes, you will use the 'less than or equal to' sign.
4(5) + 6(15) = 20 + 90 = 110. 110 is less than 120
4(5) + 4(15) = 20 + 60 = 80. 80 is less than 100
Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

Answer:
Plot points at (0,5) and (5,7)
Step-by-step explanation:
The slope-intercept equation format is...
y=mx + b
m is the slope and b is the y-intercept
Start by plotting a point at (0,5). This is where the line will intercept the y-axis (hence y-intercept). Now we need to figure out the slope...
Since slope is rise/run we can rise 2 from the point (0,5) and go to the right 5. Plot a point there. Then connect the two points and you get a line!
You can also use a graphing calculator or an online one such as Desmos.
