Answer:

The inequality shown in the graphic is y > 4x + 1

Step-by-step explanation:

Equation of a line:

The equation of a line is given by:

y = mx + b

In which m is the slope and b is the y-intercept(value of y when x = 0).

Inequality:

Values greater than the dashed line, dashed so the line is not part of the inequality, thus, the inequality is:

y > mx + b

Dashed line:

The dashed line goes through (0,1) and (1,5).

Point (0,1) means that when x = 0, y = 1, so b = 1, and:

y > mx + 1

Finding the slope:

When we have two points, the slope is given by the change in y divided by the change in x. In this question, we have point (0,1) and (1,5), so:

Change in y: 5 - 1 = 4

Change in x: 1 - 0 = 1

Slope: m = \frac{4}{1} = 4

What inequality is shown in the graph?

y > 4x + 1

Nick bought 2.5 pounds of popcorn for $8.35 how much did he pay for each pound of popcorn
marta [7]

Answer:

$3.34 for each pound of popcorn

Step-by-step explanation:

All we must do, in this case, is divide 8.35 by 2.5.

This equals 3.34.

Therefore, each pound of popcorn cost $3.34.

Don't believe me? To check, just multiply 3.34 by 2.5.

Please let me know if you need help with anything else. :)

Does anyone know the answers to this algebra question? Will give brainiest
MaRussiya [10]
Option 1 : -22

using formula

(a + b )(a - b ) = a^2 - b^2

(√10 + 2√8) (√10 - 2√8)

= (√10)^2 - (2√8)^2

= 10 - 2×2×8=10-32

= -22

2nd question answer is option 3

Use function notation to represent the area of a circle whose circumference is 148cm
ANTONII [103]
148^²/4pi
=1742.83

2 pi r=148
r=148/2pi
Now
Area=pi r^²
Pi×(148)^²/4pi^²
=148^²/4pi

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!! I CANNOT RETAKE THIS!!
irina1246 [14]

5x^3 - 4x + 1 = 0 \\\\5x^3-5x+x+1=0\\\\5x(x^2-1)+1(x+1)=0\\\\5x(x+1)(x-1)+1(x+1)=0\\\\(x+1)(5x(x-1)+1)=0\\\\(x+1)(5x^2-5x+1)=0\\\\x=-1\\\\5x^2-5x+1=0\\\\\Delta=(-5)^2-4\cdot5\cdot1=25-20=5

\Delta>0 therefore there exist two real solutions.

In total, there are 3 real roots. But, real roots are also complex roots (doesn't work the other way round!), so there are 3 complex roots.
