Whenever you are graphing an inequality,

< or > means the line is dotted
≤ or ≥ means the line is full and complete

The equation is x ≤ 3 so the answer is either A or B

x ≤ 3 means that x is less than or equal to 3, so the part that is shaded blue is supposed to be 3 and below.

The answer is A

The answer is a because there are the numbers that they are less than 3 and 3 is one of the numbers too :))

Please answer me question 3 solving part

Illusion [34]

Answer:

1. D

2. B

3. A

Step-by-step explanation:

Question 1:

The pair of <JKL and <LKM can be referred to as linear pairs. They are two adjacent angles that are formed from the intersecting of two lines.

Question 2:

Given that <KLM = x°

<KML = 50°

<JKL = (2x - 15)°

According to the exterior angle theorem, exterior ∠ JKL = <KLM + KML.

2x - 15 = x + 50

Solve for x

2x - x = 15 + 50

x = 65

Therefore, <KLM = 65°

QUESTION 3:

<JKL = 2x - 15

Plug in the value of x

<JKL = 2(65) - 15

= 130 - 15

<JKL = 115°

2 movie tickets and 1 popcorn cost $29.4 movie tickets and 4 popcorns cost $68. So how much would 3 movie tickets and 5 popcorns

Arisa [49]

Answer:

3 movie tickets would cost 44.8 5 popcorns would cost 85

Step-by-step explanation:

29.4 divided by 2 equals 14.7

29.4 plus 14.7 equals 44.8

68 divided by 4 17

68 plus 17 equals 85

The length and width of a rectangle are measured as 55 cm and 49 cm, respectively, with an error in measurement of at most 0.1 c

valentina_108 [34]

Answer:

The maximum error in the calculated area of the rectangle is $10.4 \:cm^2$

Step-by-step explanation:

The area of a rectangle with length $L$ and width $W$ is $A= L\cdot W$ so the differential of <em>A</em> is

$dA=\frac{\partial A}{\partial L} \Delta L+\frac{\partial A}{\partial W} \Delta W$

$\frac{\partial A}{\partial L} = W\\\frac{\partial A}{\partial W}=L$ so

$dA=W\Delta L+L \Delta W$

We know that each error is at most 0.1 cm, we have $|\Delta L|\leq 0.1$ , $|\Delta W|\leq 0.1$ . To find the maximum error in the calculated area of the rectangle we take $\Delta L = 0.1$ , $\Delta W = 0.1$ and $L=55$ , $W=49$ . This gives
