2. Graph each inequality on a number line:
5x + 15 < 0
Answers
Answer:
x < -3
Step-by-step explanation:
1. To put this inequality on a number line, we first must solve it.
Step 1: Subtract 15 from both sides.
[tex]5x + 15 - 15 < 0 - 15[/tex] [tex]5x < -15[/tex]Step 2: Divide both sides by 5.
[tex]\frac{5x}{5} <\frac{-15}{5}[/tex] [tex]x < -3[/tex]2. Now that we know x < -3, let's graph it!
Since it's less than, we make the number line point to the left, and we make the circle open.

If the sum of the roots of the equation 3x² + kx + 1 = 0 is 7. then what the value of k
Answers
Answer:
The value of k is -21
Step-by-step explanation:
ax² + bx + c = 0
Sum of the roots = -b/a
3x² + kx + 1 = 0
= sum of the roots = -k/3
-k/3 = 7
Now, Multiply both side by (-3) we get,
(-3)-k/3 = 7(-3)
k = -21
Thus, The value of k is -21

Write an expression that represents the perimeter of the figure below. Write your answer in simplified form. P=??
Answers
The perimeter of the figure in simplified form is expressed as: P = 2p + 2q + 2r + 4s
How to find the Perimeter of a FigureTo find the perimeter of any figure, add all the side lengths of the figure together.
Thus, the given side lengths of the figure are:
p, p, q, q, r, r, s, s, s, and s.
To find the perimeter add them together.
Perimeter of the figure = p + p + q + q + r + r + s + s + s + s
Perimeter = 2p + 2q + 2r + 4s
Therefore, the perimeter of the figure in simplified form is expressed as: P = 2p + 2q + 2r + 4s

Answers
Step-by-step explanation:
in that case we can imagine a diagonal line DB that splits the quadrilateral into 2 right-angled triangles: ADB and CDB.
the area of the quadrilateral is then the sum of the areas of the 2 triangles.
the area of a right-angled triangle is
leg1 × leg2 / 2
with the legs being the sides that enclose the 90 degree angle.
so, for ADB we get
AD × AB / 2 = 3 × 11 / 2 = 33/2 = 16.5
for CDB we get
BC × CD / 2 = 7 × 9 / 2 = 63/2 = 31.5
so, in total for the area of the quadrilateral we get
16.5 + 31.5 = 48
What part of 28 is 17?
Answers
17 is 60.7% percentage of the number 28.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
We have to find what is 17 in 28.
To find this we have to multiply x with 100 and divide it by hundred which is equal to seventeen
x/100×28=17
0.28x=17
Zero point two eight times of x equal to seventeen
Divide both sides by 0.28
x=17/0.28
We get sixty point seven one percentage
x=60.71%
Hence,17 is 60.7% percentage of the number 28.

You roll a six sided die. You are given $8 if a 6 comes up, $2 if a 3, 4, 5 comes up, and

Expected Value Table for rolling a six-sided die
Answers
We want to get the expected value for the given experiment. We will see that the expected value is $2.33
For an experiment with outcomes {x₁, ..., xₙ} each one with probability {p₁, ..., pₙ} the expected value is defined as:
EV = x₁*p₁ + ... + xₙ*pₙ
Here we have 3 outcomes:
x₁ = winning $8x₂ = winning $2x₃ = winning $0.For x₁ we need to roll a 6, this is a probability of 1 out of 6, then:
p₁ = 1/6
For x₂ we need to roll a 3, 4, or 5 (3 out of 6), then:
p₂ = 3/6
For x₃ we need to roll a 1 or a 2 (2 out of 6) so the probability is:
p₃ = 2/6
Then the expected value is:
EV = $8*(1/6) + $2*(3/6) + $0*(2/6) = $2.33
