4)
Non linear:
y = 6 -x^2
y = 2x^2 + 2
y = x^3
5)
Rate of change is also the slope
= (72 - 69) / (51 - 48)
= 3/3
= 1
Rate of change = 1
6)
First you need to find slope
(3,0) and (5,2)
Slope = (2 - 0)/(5-3) =2/2 = 1
Equation
y - 0 = 1(x - 3)
y = x - 3
Answer:
Tyler's function is correct as y = x - 3, it matched the above.
11 a. Since she runs 10km in one hour she runs 5km in half an hour and 25km in 2 and a half hours
11b. Since she runs 5 miles in one hour she runs 2.5 miles in half an hour and 12.5 mils in 2 and a half hours
11 c. Since 1.60934 kilometers = 1 mile, Clair ran the farther distance
12 a. 13.20/6 = 2.2 dollars for 1 bowl
12 b. 9/3 = 3 and if he got 3 sets of 3 free bowls he bought 24 pairs of glasses
12 c. If Malcom bought 24 pairs of glasses 24*1.80 = 43.2, so he spent 43.2 dollars on glasses
13 a. 6 to 4 or 6:4
Answer:
Step-by-step explanation:
Since triangle ADE and triangle ABC are similar, that means their sides are proportional, thus we get the equation



Thus the value of x is 4
7+ 3x= -8
-8-7=-15
-15 divided by 3= -5
-5 is the answer
