Solve for x : ax+v=3(x-c)

Answers

Answer 1

Answer:

[tex]x=\frac{-3c-v}{a-3};\quad \:a\ne \:3[/tex]

Step-by-step explanation:

--expand--

ax+v=3x-3c

--subtract v from each side--

ax+v-v=3x-3c-v

--simplfy--

ax=3x-3c-v

--subtract 3x from both side--

ax-3x=3x-3c-v-3x

--simplfiy--

--factor--(factor out the x from ax-3)

[tex]x\left(a-3\right)=-3c-v[/tex]

[tex]\frac{x\left(a-3\right)}{a-3}=-\frac{3c}{a-3}-\frac{v}{a-3};\quad \:a\ne \:3[/tex]

[tex]x=\frac{-3c-v}{a-3};\quad \:a\ne \:3[/tex]

John's phone company offers 2 cell phone plans, A and B. Both plans offer 450 free minutes per month, but plan A charges $40 per month and $0.35 for each additional minute, while plan B charges $45 per month and $0.30 for each additional minute. Which inequality shows the number of minutes, x, that John may use in a month in order to make plan B the better plan for that month?
A.
40 + 0.35(x − 450) 45 + 0.30(x − 450)

D.
40 + 0.35x > 45 + 0.30x

Answers

Answer: 45 + 0.30(x-450) > 40 + 0.35(x-450)

Step-by-step explanation:

Given: Free minutes = 450

For plan A,

Fix charge = $40

Charge per minute after free minutes  = $0.35

For plan B,

Fix charge = $45

Charge per minute after free minutes  = $0.30

Let x be the additional minutes.

Charges according to plan A = 40 + 0.35(x-450)

Charges according to plan B = 45 + 0.30(x-450)

If plan B is better than plan A.

45 + 0.30(x-450) > 40 + 0.35(x-450)

Required inequality : 45 + 0.30(x-450) > 40 + 0.35(x-450)

Really hard geometry problems. Please help!

Answers

Answer: For #3 the answer is 48 degrees, #4 is 70 degrees

Step-by-step explanation:

3. CGA and BGD are verticle angles which means they are congruent, and (2x-10)+(x+4)+(x+10) is 180. Which gives you X=44, then you substitute x into x+4 which gives you 48.

4. CEB and BED are supplementary which means they make up 180. BED and CEA are verticle angles which means they are congruent. We know CEB is 110 which means BED is 70 because 180-110=70. BED and CEA are verticle angles which means CEA is also 70 degrees

Answer:

i think #3 is 93 and #4 is 70

Step-by-step explanation:

a full circle is equal to 360

for #3, i used the equation (2x-10) + (x+4) + (x+10) = 360

combine all like terms and get 4x + 4 = 360

subtract 4 from both sides

4x + 4 = 360

4x = 356

divide 4 from both sides

x = 89. from here put 89 where x is . angle BGD and angle CGA are the same so 89 + 4 = 93

for #4, use the equation 45 + 3x - 19 = 110

combine like terms and get 26 + 3x = 110

subtract 26 from both sides and then divide by 3

3x = 84

x = 28

place 28 where x is and find the matching angle which is 70.

Find the equation of the perpendicular bisector of a line segment whose end points are (-3,9) and (-1,5)

Answers

First find the equation of y.

[tex]y=mx+n=\frac{\Delta y}{\Delta x}x+n[/tex]

Find the slope m.

[tex]m=\frac{5-9}{-1-3}=\frac{-4}{-4}=1[/tex].

Pick one point, I'll pick (-3, 9). Insert coordinates in equation then compute n.

[tex]9=1(-3)+n\implies n=12[/tex].

The equation of a line y is:

[tex]y=x+12[/tex].

The perpendicular line [tex]y_{\perp}[/tex] is same like the normal line except its slope m becomes:

[tex]k=-\frac{1}{m}=-1[/tex].

The equation of a perpendicular bisector is thus:

[tex]y_{\perp}=-x+12[/tex].

Hope this helps.

Answer:

[tex]y = \frac{1}{2} x + 3[/tex]

Step-by-step explanation:

Using the given points, first find the slope:

m = (₂ - y₁) / (x₂ - x₁)

   = (5 - 9) / (-1 - (-3))

   = -4 / 2

    = -2

Find y-intercept by using anyone of the give points and slope from above:

y = mx + b

5 = -2(-1) + b

5 = 2 + b

b = 3

With the m and b, you can make equation of line:

y = mx + b

y = -2x + 3

To find the perpendicular slope, make it opposite and inverse it.

m = -2 becomes 1/2

Regular equation of line:

y = -2x + 3

Perpendicular equation of line:

[tex]y = \frac{1}{2} x + 3[/tex]

When the function y=x is changed to y=|x|, how is the graph affected?
A. All points for x 0 are reflected over the line y=x.
B. All points for x 0 are reflected over the line y=x.
D. All points for x > 0 are reflected over the x-axis.

Answers

Answer:

First, the function:

y = x

Is:

Positive if x > 0

Negative if x < 0

Now, on another hand, the function y = IxI is:

Positive if x < 0

Positive if x > 0.

Then the only part that changes is the negative side of the domain, and the thing that changes is the sign (the change of sign is equivalent to a reflection over the x-axis or the line y = 0".

Then the correct option is:

"All points for x < 0 are reflected over the x-axis"

I suppose that this is option C, the missing one.

-3(8x-2)=9-21x Original equation
8x-2=-3+7x
8x+1=7x
1=-x
-1=x

Answers

Answer:

Below in bold

Step-by-step explanation:

-3(8x - 2) = 9 - 21x

~Divide -3 to everything

8x - 2 = -3 + 7x

~Add 3 to both sides

8x + 1 = 7x

~Subtract 8x to both sides

1 = -x

~Divide -1 to both sides

-1 = x

Note that this isn't the most used way to solve equations because you would typically use distribution to simplify the left side.

Best of Luck!

Over the course of a month, Katniss caught three times as many squirrels as deer. She also caught five less rabbits than squirrels. The total number of animals she caught is ten more than four times the number of deer caught. How many rabbits did Katniss catch? Help steps

Answers

Answer:

10 rabbits

Step-by-step explanation:

Let us represent

Number of rabbits = x

Number of squirrels = y

Number of deer = z

Katniss caught three times as many squirrels as deer.

y = 3z

She also caught five less rabbits than squirrels.

y = x - 5

The total number of animals she caught is ten more than four times the number of deer caught.

x + y + z = 4 × z + 10

x + y + z = 4z + 10

How many rabbits did Katniss catch?

Number of rabbits = x

We make x subject of the formula

x + y + z = 4z + 10

x = 4z + 10 - y - z

y = 3z

x = 4z + 10 - 3z - z

x = 4z - z - 3z + 10

x = 4z - 4z + 10

x = 0 + 10

x = 10

Therefore, the number of rabbits Katniss caught is 10 rabbits

To determine the unit rate of 1/4 kilometer in 1/3 hour.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

What is the rate of change?

The rate of change is defined as the change in value with the rest of the time is called rate of change.

Here,
The unit rate of 1/4 kilometer in 1/3 hour,
Rate = (1 / 4 kilometer) / (1 / 3 hour)
Rate = 1 /  4 / 1 / 3
Rate = 3 / 4 Kilometer per hour.

Thus, the required rate of 1/4 kilometer in 1/3 hour is 3 / 4 Kilometer per hour.
