Answer:

y ≤ 1/3 x - 1.3.

Step-by-step explanation:

First find the equation of the line:

The slope = (-0.3 - (-1.3) / (3 - 0).

= 1/3 so the equation is y = 1/3x + b where b is a constant.

b is the y-intercept which is the value of y when x = 0 . We see that it is -1.3 ( from the point 0, -1.3).

Since the line is continuous and the shading is below this line the inequality sign is 'less than or equal to', ≤.

Answer: D

Step-by-step explanation:

Firstly. we can eliminate options A and B because the shaded region is below the line.

Next, we are given the point: (0,-1.3) this means -1.3 will appear in the

inequality, giving us the answer D

Which is the best description of the equivalency of the two expressions? Expression 1 Expression 2 5 x squared minus 2 x minus 4

lina2011 [118]

Answer:

The correct option is (D).

Step-by-step explanation:

The two expressions are:

$\text{Exp}_{1}=5x^{2}-2x-4+6x+3\\\\\text{Exp}_{2}=6x^{2}-6x+6-x^{2}+10x-7$

On simplifying both the expressions we get:

$\text{Exp}_{1}=5x^{2}+4x-1\\\\\text{Exp}_{2}=5x^{2}+4x-1$

Compute the value of both expressions for x = 2 as follows:

$\text{Exp}_{1}=5(2)^{2}+4(2)-1=27\\\\\text{Exp}_{2}=5(2)^{2}+4(2)-1=27$

The value of both expressions are same for x = 2.

Thus, the correct option is:

"They are equivalent because when x = 2, the two expressions have the same value."

Angle AOC has what measurement according to the protractor? A. 150° B. 50° C. 30° D. 130°

maxonik [38]

Answer:

∠AOC = 50°

B is correct.

Step-by-step explanation:

In the given figure of protractor measure the ∠AOC

Please find the attachment of protractor.

OA is horizontal line which is base of protractor.

In angle AOC, two legs OA and OC

OA is base of protractor. OC another leg.

Now we see position of leg OC of angle AOC.

∠AOC is acute angle. So, see the number bottom of protractor.

Hence, the measure of ∠AOC is 50°
