Work Shown:

Let x be the additive inverse of 9

This means it adds to 9 to get 0

x+9 = 0 which solves to x = -9 after subtracting 9 from both sides.

So -9+9 = 0 and 9+(-9) = 0.

Answer:

-9.

Step-by-step explanation:

Because  9 + (-9) = 0.

Answer: 9

Answer:

The last option line DG is congruent to line GE

Step-by-step explanation:

Median: a segment whose endpoints are a vertex of a triangle and the midpoint of the opposite side

So basically G is the midpoint of DE because FG is the median.

The last option, we can conclude that line DG is congruent to line GE

Median is such a number for the arranged data set(ascending or descending order) such that to its left and to its right belong same number of observations.

Median is a line segment whose endpoints are a vertex of a triangle and the midpoint of the opposite side.

We are given that FG is an median.

Thus, basically G becomes the midpoint of DE because FG is the median.

So, DG = GE

Hence,

The last option, we can conclude that line DG is congruent to line GE

Answer:

  see attached (blue line)

Step-by-step explanation:

The slope in the first interval (0 to 2) will be -1, down from the y-intercept of 1.

The slope in the second interval will be 2. After that, the slope is zero, so the graph is a horizontal line.

The blue line in the attached is the graph of f(x).

The expected number of people you will have to ask before you find someone with jumper cables is 6.25.

Step-by-step explanation:

        [tex]p_{X}(k)=(1-p)^{k-1}p;\ k={1, 2, 3...}[/tex]

        [tex]p_{X}(k)=(1-p)^{k}p;\ k={0, 1, 2, 3...}[/tex]

In this case the first scenario follows.

X = number of people you will have to ask before you find someone with jumper cables.

p = 0.16

Compute the expected number of people you will have to ask before you find someone with jumper cables as follows:

[tex]E(X)=\frac{1}{p}\\\\=\frac{1}{0.16}\\\\=6.25[/tex]

Thus, the expected number of people you will have to ask before you find someone with jumper cables is 6.25.

Answer:

Option A: Axis of symmetry: x = -0.5; Vertex: (-0.5, 0.75); f(x) = x2 + x + 1

Step-by-step explanation:

1) The axis of symmetry of quadratic graph is the vertical line that divides the graph curve into two congruent halves. In this case, it is: x = -0.5

2) Vertex is the point at which the graph curve changes direction or simply coordinates of the crest or trough of the curve.

The graph given has a trough with the coordinates: x = -0.5, y = 0.75. This is (-0.5, 0.75)

3) The roots of a quadratic equation are the points where the curve crosses the x-axis. In this case, it doesn't cross and so we have imaginary roots.

Now, formula for line of symmetry is; x = -b/2a

Thus; -b/2a = -0.5 or -b/2a = -1/2

Thus, b = 1 and a = 1

Our first and second terms will now be;

x² + x

Looking at the options, the only one with x² + x as it's first 2 terms is option A.

Thus, the complete equation will be x² + x + 1

Answer:

Step-by-step explanation:

Formula to be used,

A = [tex]P(1+\frac{r}{n})^{nt}[/tex]

Here, A = Final amount

P = Principal amount

r = rate of interest

n = Number of compounding (In a year)

t = Duration of investment (In years)

Question (5)

P = $4250

r = 0.015

n = 4

t = 3 years

A = [tex]4250(1+\frac{0.015}{4})^{4\times 3}[/tex]

A = [tex]4250(1.00375)^{12}[/tex]

A = $4445.24

Part (C)

1). P = $6000

   r = 0.03

   n = 2

   t = 10 years

  A = [tex]6000(1+\frac{0.03}{2})^{2\times 10}[/tex]

      = [tex]6000(1.015)^{20}[/tex]

      = $8081.13

2). P = $9000

    r = 0.05

    n = 2

    t = 8 years

    A = [tex]9000(1+\frac{0.05}{2})^{2\times 8}[/tex]

        = [tex]9000(1.025)^{16}[/tex]

        = $13360.55

Answer:

The emergency medical technician made $739.12 per week

Step-by-step explanation:

Given that:

Per hour pay = $19.71

One month earning of emergency medical technician = $3326.06

Weeks in the following month = 4.5

For per week income, we will divide the monthly salary by number of weeks in the month.

Per week income = [tex]\frac{3326.06}{4.5}[/tex]

Per week income = $739.12

Hence,

The emergency medical technician made $739.12 per week

Answer:

B) Hypotenuse = Leg ∙ √2

Step-by-step explanation:

This is a well-known ratio in the 45-45-90 right triangle, but we can derive it.

An isosceles right triangle has two congruent legs forming the right angle and the hypotenuse opposite the right angle. The Pythagorean theorem works since it is a right angle.

Normally, the legs are a and b, and the hypotenuse is c, and we have

a^2 + b^2 = c^2

Here the legs are congruent, so we have a = b.

Substituting a for b, we have

a^2 + a^2 = c^2

2a^2 = c^2

c^2 = 2a^2

c = a√2

Answer: B) Hypotenuse = Leg ∙ √2

Answer:

167 pairs

Step-by-step explanation:

Represent jeans with J and shirts with S

[tex]S = 2J[/tex]

[tex]Amount = \$500[/tex] --- Maximum

Required

Determine the number of pair of jeans he can buy

To represent as an inequality, we have:

[tex]S + J \leq Amount[/tex]

[tex]S + J \leq 500[/tex]

Substitute 2J for S

[tex]2J + J \leq 500[/tex]

[tex]3J \leq 500[/tex]

Divide through by 3

[tex]J \leq 500/3[/tex]

[tex]J \leq 167[/tex]

Hence, without exceeding $500, Jess can buy 167 pairs of jeans
