Explain the steps of graphing 2x + 4≤ 12.
Answers
Answer:
Step-by-step explanation:
First, you want to simplify so the equation would be x+2≤6 or x≤4
Because you are solving for x you want to graph a vertical line on 4.
Then you shade on the left side of the line because it is less than or equal to. If it were just less then you would do a dashed line on 4 but because it is also equal to 4 then you keep it a solid line.
I recommend using Desmos graphing calculator.

Answer:
Answers in explanation.
Step-by-step explanation:
Finding angle 1:
52 + angle 1 = 180
angle 1 = 128
Finding angle 2:
128 (angle 1) + angle 2 = 180
angle 2 = 52
Finding angle 5:
52 + 47 + angle 5 = 180
angle 5 = 81
Finding angle 3:
angle 2 + angle 3 + angle 5 = 180
52 + angle 3 + 81 = 180
angle 3 = 47
Finding angle 4:
angle 3 + angle 4 = 180 OR angle 4 + 47 = 180
47 + angle 4 = 180
angle 4 = 133
Assume that three fifths of the population has long hair and and one tenth of the poulation has blue eyes. What is the probability that a person does not have long but does have blue eyes?

In one part of a kennel, 5/8 of the 24 dogs are male. In another part of the kennel, 4/5 of the 30 dogs are male.
How many male dogs are in the two parts of the kennel?
Answers
Answer:
39
Step-by-step explanation:
The computation of the number of male dogs in the two parts of the kennel is shown below:
In one part, the male dogs are
= 24 × 5 ÷ 8
= 15
In the another part, the male dogs are
= 30 × 4 ÷ 5
= 24
So, the total male dogs is
= 15 + 24
= 39

The lines shown below are perpendicular. If the green line has a slope of
2/5 , what is the slope of the red line?
Answers
Answer:
-5/2
Step-by-step explanation:
for perpendicularity;
[tex]m1 = \frac{ - 1}{m2} [/tex]
where m1 is first slope
and m2 is second slope
so here, let m1 be green line slope
and m2 be red line slope
thus,
[tex]m2 = \frac{ - 1}{m1} [/tex]
[tex]m2 = \frac{ - 1}{ \frac{2}{5} } = - 1 \div \frac{2}{5} [/tex]
[tex] = - 1 \times \frac{5}{2} = \frac{ - 5}{2} [/tex]

How much must be added to each of the three number 1, 11, and 23 so that together they form a geometric progression?
Answers
Answer:
49
Step-by-step explanation:
Let the three numbers be a1, a2, a3
Let the number to be added to form a geometric progression = x
a1 = 1 + x ; a2 = 11 + x ; a3 = 23 + x
For a geometric progression :
a2 = a1 * r
a2 = (1+x)r
11+x = (1+x)r - - (1)
r = (11+x) / (1+x) ---(1)
a3 = a2 * r
a3 = (11+x)r
23+x = (11+x)r - - -
r = (23+x) / (11+x) - - (2)
Equate (1) and (2)
(11+x) / (1+x) = (23+x) / (11+x)
(11+x) * (11+x) = (23+x) * (1+x)
121 + 22x + x² = 23 + 24x + x²
121 + 22x + x² - x² - 24x - 23 = 0
98 - 2x = 0
-2x = - 98
x = 98 / 2
x = 49

Answers
you can use the formula of pythagoras theorem to know what of them is wrong
in the first case
-5^2 + 12^2 =169
13^2=169 ( it's a right equation so it can be lengths of right angle tri )
in the second case
_9^2 + 12^2 =225
17^2 not equal 225
so these are the lengths that can't be a right angle triangle
