A) give a verbal description of the subset of real numbers represented by the inequality or the interval, B) sketch the subset on the rest of real number line, and C) state whether the interval is bounded or unbounded

Answer:

A) y = 4

B) x = 5

Step-by-step explanation:

for a), the line is horizontal. The y-value doesn't change--it stays at 4.

For b), the line is vertical. So the x-value doesn't change--it stays at 5.

Answer:

Step-by-step explanation:

The slope or, gradient is the rate of change of a linear function( a function which can be represented by a line). We find a slope between two arbitrary  pair of points( arbitrary means what the question given us). One point we are given is (0,4) and an another point we are given is (2,1). Now we use the slope formula,

[tex]\frac{change in y }{change in x}[/tex]

So let plug in the values,

[tex]\frac{4-1}{0-2} =\frac{3}{-2} =-\frac{3}{2}[/tex]

The slope is -3/2

Answer:

x = 8

Step-by-step explanation:

[tex]y = \frac{1}{2} x - 4[/tex]

[tex]0 = \frac{1}{2} x - 4[/tex]

[tex]0 = x - 8[/tex]

[tex] - x = - 8[/tex]

[tex]x = 8[/tex]

Answer:

Step-by-step explanation:

First multiply the -5 to (a+6)

The equation will look like this

-21 - 8a = -5a -30

then move the numbers around where you have a value times on one side, and a normal value on the other

add -5a to -8a, and add -21 to -30

the equation should look like this:

-13a = -51

then you need to get the a by itself, so divide -13 by -51

a= 13/51 (as a fraction with 13 on top)

Answer:

a = 4.98

b = 0.44

B = 5

Concept:

Here, we need to know the idea of the Pythagorean theorem and basic trigonometry ratios.

Pythagorean theorem: a² + b² = c²

Trigonometry ratios:

Solve:

**Disclaimer** The question did not clarify which place did it required to be rounded to as some of the values are infinite. I rounded to the hundredth place. If it is fine, then you may refer to my answers. If it is not, then you may tell me and I'll redo it.

Given information

c = 5

A = 85°

PART ONE: Find the value of [a]

sin (A) = Opposite / Hypotenuse = a / c

sin (85) = a / 5

a = 5 · sin (85)

a = 4.98

PART TWO: Find the value of [b]

cos (A) = Adjacent / Hypotenuse = b / c

cos (85) = b / 5

b = 5 · cos (85)

b = 0.44

PART THREE: Find the value of [B]

Since the triangle as a right angle sign, meaning it is a right triangle.

Therefore, the corner angle is 90°.

90 - 85 = 5°

Hope this helps!! :)

Answer:

Perimeter = 16 cm

Step-by-step explanation:

The formula for a square's area  = s^2 where the length of the side is s.

s^2 = 16                   Take the square root of both sides

sqrt(s^2) = sqrt(16)

s = 4

The perimeter is the same

P = 4*s

P = 4 * 4

P = 16

Answer:

16

Step-by-step explanation:

Square root of 16 = 4cm

4 sides, 4 * 4 = 16cm

Answer:

Vertex is (-8, 4)  not one of the answers offered!

Step-by-step explanation:

Factor -1/8 out of the first two terms. Leave a space inside parentheses in which to add a number.

[tex]y=-\frac{1}{8}(x^2 + 16x + \text{-----})-4[/tex]

Complete the square by squaring half the coefficient of x and adding it in the space.

[tex](\frac{16}{2})^2=64[/tex]

Add 64 in the space you made, then compensate for that at the end of the expression by subtracting  [tex]-\frac{1}{8}(64)=-8[/tex]

[tex]y=-\frac{1}{8}(x^2+16x+64)-4+8\\y=-\frac{1}{8}(x+8)^2+4[/tex]

The x-coordinate of the vertex is the opposite of +8, the number inside the parentheses.  The y-coordinate of the vertex is the number at the end of the expression.

V(-8, 4)

Answer:

Answer is 7:20

It's basically asking "what is the ratio of math teachers to total teachers?" assuming there are only math and science teachers at this school. For the sake of simplicity, let's just go with that. We have 14 math teachers and 14+26 = 40 teachers total. The ratio of math to total is 14:40 which reduces to 7:20 when we divide both parts of the ratio by the GCF 2.

Step-by-step explanation:

Answer:

the ratio is

14:26

but you can leave the answer like this the two numbers can be divided by 2 so

14/2=7 and 26/2=13

then the answer is 7:13.

Answer:

The circle has like an equation: (x+3)²+(y-2)²=r²

If x=1 then y=5 ==>(1+3)²+(5-2)²=r²==>4²+3²=r²==>r=5 (the radius)

if x=-7 then (-7+3)²+(y-2)²=25 ==>  (y-2)²=25-16==>y=2+3 or y=2-3

The points (-7,5) and (-7,-1) are on the circle.

Answer:

7xy

Step-by-step explanation:

35+ x + 60 = 180

95 + x = 180

x = 180 – 95

x = 85

x + 47 + 75 = 180

x + 122 = 180

x = 180 – 120

x = 58

105 ° = 3 x° –> Opposite angles ,

x = 105 / 3

x = 35

3x = 3(35) = 105°

Answer:

Step-by-step explanation:

You simply need to substitute the numbers in the x column into the equations in the topmost row. The answers are the values of a, b, c, d, e, and f.

Look at the filled in cells.

In the x column, we have -2, and the topmost row we have [tex]2^x[/tex]. The answer is given as [tex]\frac{1}{4}[/tex]. This is because [tex]2^{-2} = \frac{1}{2^{2} } = \frac{1}{4}[/tex]

Repeat this for the values that you need to find.

Answer: Cheetah

Step-by-step explanation: I got it right on the test :)

The animal with the least difference is cheetah with a value of 5

From the double bar chart attached :

Life span in wild is = blue bar

Life span in wild is = blue bar Life span in captivity = brown bar

Calculating the approximate difference between the two bar values as obtained from the graph :

CHEETAH = 17 - 12 = 5

POLAR = 35 - 20 = 15

TIGER = 26 - 20 = 6

GIANT PANDA = 30 - 20 = 10

LEOPARD = 28 - 20

The animal with the least difference between it's span in the wild and in captivity is CHEETAH with a value of 5.
