Your friend is trying to grow her hair as long as her cousin's hair. The table (attached) shows their hair lengths (in inches) i
astra-53 [7]

Answer:

a)  y = 1/2x + 5/2

    y = 2/5x + 29/5

b)  hair will be 19 inches for both at 33 months

Step-by-step explanation:

a) rate of growth of friend's hair:  (3, 4) (8, 6.5)  

(6.5 - 4) ÷ (8 - 3) = 2.5/5 or 1/2

find the y-intercept of equation for growth of friend's hair:

y = mx + b

4 = 1/2(3) + b

4 = 3/2 + b

8/2 - 3/2 = b

5/2 = b

equation for growth of friend's hair:

y = 1/2x + 5/2

rate of growth of cousin's hair:  (3, 7) (8, 9)  

(9 - 7) ÷ (8 - 3) = 2/5

find the y-intercept of equation for growth of cousin's hair:

y = mx + b

9 = 2/5(8) + b

9 = 16/5 + b

45/5 - 16/5 = b

29/5 = b

equation for growth of cousin's hair:

y = 2/5x + 29/5

b) y = 1/2x + 5/2

   y = 2/5x + 29/5

1/2x + 5/2 = 2/5x + 29/5

5/10x + 25/10 = 4/10x + 58/10

1/10x = 33/10

10x = 3300

x = 33

Neko [114]

Answer:

D. two acute angles

Step-by-step explanation:

Let us quickly plot the vertices on a graph to obtain the figure in the attachment.

Connecting the four points gives a square.

We know a square has the following properties.

A. four right angles

.......True

B. four vertices

................True

C. two sets of parallel lines

......True

D. two acute angles...................False.....A square has four right angles.

Write the equation of the function g(x) if g(x) = f(x - 3) +1 and f(x) = x3 + 1.
stealth61 [152]

Answer:

Solution,

f(x) = x^{3} + 1

Put x = x - 3,

f(x - 3) =  (x-3)^{3} + 1

Now,

g(x) = f(x - 3) + 1

or, g(x) =[ (x-3)^{3} +1 ] + 1

or, g(x) = x^{3} -9x^{2} + 27x - 1 + 1+1

or, g(x) = x^{3} - 9x^{2} +27x + 1
