Which linear inequality is represented by the graph?

WARRIOR [948]

Step 1

Find the slope of the line

Let

$A(0,1)\\B(2,5)$

the slope is equal to

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

substitute

$m=\frac{5-1}{2-0}$

$m=\frac{4}{2}$

$m=2$

Find the equation of the line

we know that

the equation of the line into slope-intercept form is

$y=mx+b$

where

m is the slope

b is the y-intercept

in this problem we have

$m=2$

$b=1$ ------> the y-intercept is the point A

substitute

$y=2x+1$

Step 2

Find the equation of the inequality

we know that

the solution is the shaded area above the dotted line

above dotted line---------> represent the symbol ( $>$ )

the inequality is

$y>2x+1$

therefore

the answer is

$y>2x+1$

Andrea wants a diamond necklace and its selling price is $60. There was a discount of 5%. How much did Andrea pay?

devlian [24]

So discount means less so find 5%
remember that percent means parts out of 100 so
5%=5/100=1/20
find 1/20 of 60
'of' means mulitpy in math
1/20 ties 60=3
5%=3
discoutn is 3
subtract 3 from 60
60-3=57

she paid $57

Answer:

132 square cm = 20.46 square inches

Step-by-step explanation:

Total surface area = area of base (square) + 4 x area of one triangle.

$= {6}^{2} + 4 \times \frac{1}{2} \times 6 \times 8 \\ = 36 + 2 \times 48 \\ = 36 + 96 \\ = 132 \: {cm}^{2} \\= 20.46\: inches^2$
