Answer:

Step-by-step explanation:

y = 2x - 1

y = x - 8 ------ (i)

substitute y = 2x - 1 in equation (i)

2x - 1 = x - 8

2x = x - 8 + 1

2x = x - 7

2x - x = -7

x = -7

Substitute x value in equation (i)

y = -7 - 8

y = -15

Vesnalui [34]

Answer:

a) 30m

b) 50.6m²

Step-by-step explanation:

Perimeter = 2(length + width)

= 30.08 m

Area = length × width

9.96 × 5.08

50.5968 m²

Natalie found a tennis ball outside a tennis court. She picked up the ball and threw it over the 12-foot fence into the court. T

dolphi86 [110]

Answer:

Natalie cannot make it over the fence.

Step-by-step explanation:

After reading the statement, we must demostrate if the following inequation is possible, that is:

$-16\cdot t^{2}+18\cdot t+5 \ge 12$

After some algebraic handling we find this equivalent expression:

$16\cdot t^{2}-18\cdot t +7\le 0$ (1)

The polynomial is factorized by the Quadratic Formula:

$\left(t-0.563-i\,0.348)\cdot (t-0.563+i\,0.348)\le 0$

Since all roots are complex, we conclude that Natalie cannot make it over the fence.
