Answer:

x = ±4

Step-by-step explanation:

Step 1: Write out quadratic

2x² - 5 = 27

Step 2: Add 5 to both sides

2x² = 32

Step 3: Divide both sides by 2

x² = 16

Step 4: Take the square root of both sides

x = ±4

∴ x can equal -4 or 4

Which linear inequality is represented by the graph?

Tema [17]

Answer:

$y\leq \frac{2}{3}x+\frac{1}{5}$

Step-by-step explanation:

step 1

Find the equation of the solid line

Find the slope

we have

(0,0.2) and (3,2.2)

$m=(2.2-0.2)/(3-0)=\frac{2}{3}$

The y intercept b is equal to

$b=0.2=\frac{2}{10}=\frac{1}{5}$

the equation of the solid line in slope intercept form is equal to

$y=\frac{2}{3}x+\frac{1}{5}$

step 2

Find the equation of the inequality

we know that

The solution of the inequality is the shaded area below the solid line

therefore

$y\leq \frac{2}{3}x+\frac{1}{5}$

A box contains marbles of five different colors: red, green, blue, yellow, and purple. there is an equal number of each color. a

olga nikolaevna [1]

P(red) = 1/5 [that says "probability of getting red is one fifth"
P(green) = 1/5
P(blue) = 1/5
P(yellow) = 1/5
P(purple) = 1/5

The reason the fractions are all the same is that there are equal numbers of each color. For example, if there were 7 marbles of each color, there would be a total of 35 marbles.

P(red) = 7/35 = 1/5
Similar for the other colors.
