Answer:

D)x²-9x

Step-by-step explanation:

A quadratic expression is one in which the greatest exponent of x is 2.

A binomial is an expression with two terms added or subtracted.

The only choice that fits both of these criteria is D, x²-9x.

Find y. Round to the nearest tenth: 290 500 ft y X y = [ ? ]ft

hjlf

Answer:

y = 242.4

x = 437.3

First find the inner angle:

90° - 29°

61°

[ given hypotenuse = 500 ft ]

using sine rule:

$\sf sin(x)= \dfrac{opposite}{hypotensue}$

$\hookrightarrow \sf sin(61)= \dfrac{x}{500}$

$\hookrightarrow \sf x=sin(61)*500$

$\hookrightarrow \sf x=437.3$

using pythagoras theorem:

a² + b² = c²

y² + (437.3)² = 500²

y = √58760.1

y = 242.4

Answer:

The last answer. The slope 1.8 is positive so it will slope upward from left to right. Since 1.8 is less than 2.5 the slope of the line will be less steep.

The function below crosses the x-axis once. y=3x^2-8x+8

Mekhanik [1.2K]

I believe it is false because it only passes through the y-axis not the x-axis.

The difference of the product of a number, y, and 3 and 24 is 237. Write an equation

lbvjy [14]

y + 3 +24 = 237

y + 27 = 237

y + 27 - 27 = 237 -27

y = 210
