Answer:

2.16 gallons

Step-by-step explanation:

Area to be painted:

9 ft × 12 ft = 108 ft²

<u>Pain required:</u>

50 ft² = 1 gallon ⇒ 1 ft² = 1/50 gallon

108 ft² = ?

108 × 1/50 = 2 8/50 = 2.16 gallons

Find the intersection points of the linear and quadratic functions shown below f(x)=2x-5 g(x)= x2+2x-21

Mice21 [21]

Answer:

$(-4,-13)$ and $(4,3)$ the intersection points.

Step-by-step explanation:

Intersection point of two functions is a common point which satisfies both the functions.

Given functions are,

$f(x)=2x-5$

$g(x)=x^2+2x-21$

For a common point of these functions,

$f(x)=g(x)$

$2x-5=x^2+2x-21$

$-5=x^2-21$

$0=x^2-16$

$x^2=16$

$x=-4,4$

For $x=-4$ ,

$f(-4)=g(-4)=2(-4)-5$

$=-13$

For $x=4$ ,

$f(4)=g(4)=2(4)-5$

$=3$

Therefore, $(-4,-13)$ and $(4,3)$ the intersection points.

Write an equation of the line that passes through the given points.<br> question (-4, 3), (O, -10)

expeople1 [14]

Answer:

$Y=(\frac{4}{7}) x+2$

Step-by-step explanation:

$Y=mx+b$

$M=\frac{x2-x1}{y2-y1}$

$M=\frac{0-(-4)}{-10-3}$

$M=\frac{-4}{-7}$

$Y=(\frac{4}{7}) x+2$
