Answer:

The inequality that graphed is y ≥ 2x + 2 ⇒ B

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

  • m is the slope of the line
  • b is the y-intercept

In the given figure

∵ The equation of the line is y = m x  + b

∵ The line intersects the y-axis at the point (0, 2)

∴ b = 2

→ Use the rule of the slope m = \frac{y2-y1}{x2-x1} to find m

∵ The line passes through points (-1, 0) and (0, 2)

∴ x1 = -1 and y1 = 0

∴ x2 = 0 and y2 = 2

→ Substitute them in the rule above

∴ m = \frac{2-0}{0--1} = \frac{2}{0+1} = 2

→ Substitute the values of m and b in the equation above

∴ The equation of the line is y = 2x + 2

∵ The line is solid

∵ The shaded area is over the line

∴ The sign of inequality is ≥

∴ The inequality is y ≥ 2x + 2

∴ The inequality that graphed is y ≥ 2x + 2

First you divide L+W by 2 and you would get A/2=L+W then you would subtract L and get A/2 -L=W

Use the diagram of the right triangle above and round your answer to the nearest hundredth.
Yakvenalex [24]

Answer:

value of a = 6.93 m

hence , (b.)

Step-by-step explanation:

the given triangle is a right angled triangle, so

by using trigonometry.

=》

\tan(a)   = \tan(30)  =  \frac{1}{ \sqrt{3} }

and we know,

=》

\tan(a)  =  \frac{a}{b}

so, by above values of tan ( a ) we get,

=》

\frac{a}{b}  =  \frac{1}{ \sqrt{3} }

=》

\frac{a}{12}  =  \frac{1}{ \sqrt{3} }

=》

a = \frac{12}{ \sqrt{3} }

=》

a = 4 \sqrt{3}

=

=》

a = 6.93

hence, a = 6.93 m

A storekeeper has two kinds of flour, one selling for 65 cents per pound, and the other selling for 95 cents per pound. How many
Murrr4er [49]

Answer:

The amount of 65 cents per pound flour to use is 40 pounds and the amount of 95 cents per pound flour to use is 60 pounds

Step-by-step explanation:

Let

x ----> amount of 65 cents per pound flour to use

y----> amount of 95 cents per pound flour to use

we know that

x+y=100 ----> y=100-x ----> equation A

0.65x+0.95y=0.83(100) ----> equation B

substitute equation A in equation B

0.65x+0.95(100-x)=0.83(100)

Solve for x

0.65x+95-0.95x=83

0.95-0.65x=95-83

0.30x=12

x=40\ lb

Find the value of y

y=100-40=60\ lb

therefore

The amount of 65 cents per pound flour to use is 40 pounds and the amount of 95 cents per pound flour to use is 60 pounds

Find c. Round to the nearest tenth
sergeinik [125]

Answer:

c = <u>0.5 cm</u>

Step-by-step explanation:

Using the Sine rule in the triangle, then

=  ( cross- multiply )

c × sin105° = 2 × sin15° ( divide both sides by sin105°

c =  ≈ 0.5 cm ( to the nearest tenth )
