Answer:
0
Step-by-step explanation:
2(3x – 5) = -12 + 6x
6x - 10 = 6x - 12
Subtract 6x from both sides.
-10 = -12
Since -10 = -12 is a false statement, there is no solution.

What is the area of her pasture if she decides to make two sides of 500 ft. Each and uses the angle you found in part (a)?
Answer:
(a) The angle between them is 90 degrees
(b) The area is 125000ft^2
Step-by-step explanation:
Given
See attachment for complete question
Solving (a): Angle that gives the maximum area.
The area of a triangle is:
[tex]Area = \frac{1}{2}abSinC[/tex]
Where C is the angle between a and b.
The maximum area of a triangle is:
[tex]Max\ Area = \frac{1}{2}ab[/tex]
Equate both areas to find C
[tex]\frac{1}{2}ab\ sinC = \frac{1}{2}ab[/tex]
Divide both sides by [tex]\frac{1}{2}ab[/tex]
[tex]sinC = 1[/tex]
Take arc sin of both sides
[tex]C = sin^{-1}(1)[/tex]
[tex]C = 90[/tex]
The angle between them is 90 degrees
Solving (b): The area when [tex]a = b =500[/tex]
The area of a triangle:
[tex]Area = \frac{1}{2}abSinC[/tex]
So:
[tex]Area = \frac{1}{2} * 500 * 500 * sin(90)[/tex]
[tex]Area = \frac{1}{2} * 500 * 500 * 1[/tex]
[tex]Area = \frac{250000}{2}[/tex]
[tex]Area = 125000[/tex]

Jerry has a new job and earns a salary of $45,000. Victoria has a new job and earns a salary of $54,000. Jerry will receive a salary increase of $2,500 per year, and Victoria will receive a salary increase of $1,500 per year. Which equation can be used to find x, the number of years it will take Jerry to earn the same salary as Victoria? F 45,000 x + 2,500 x = 54,000 x + 1,500 x G 45,000 x + 2,500 = 54,000 x + 1,500 H 45,000 + 2,500 x = 54,000 + 1,500 x J 45,000 x + 2,500 x = 54,000 x + 1,500
Answer:
H) 45,000 + 2,500 x = 54,000 + 1,500x
Step-by-step explanation:
Let the number of years be represented as x
For Jerry
Jerry has a new job and earns a salary of $45,000.Jerry will receive a salary increase of $2,500 per year,
The equation is
45,000 + 2,500x
Victoria has a new job and earns a salary of $54,000. and Victoria will receive a salary increase of $1,500 per year.
The equation is :
54,000 + 1,500x
The equation that can be used to find x, the number of years it will take Jerry to earn the same salary as Victoria is given as
Equation for Jerry = Equation for Victoria
45,000 + 2,500x = 54,000 + 1,500x

Which equation represents a line which is parallel to the line 7x+2y=-8
Answer:
y = -7/2x +17
Step-by-step explanation:
First, lets put the original equation into slope intercept form which is y=mx+b
7x + 2y = -8
subtract 7x on both sides
2y = -7x -8
divide by 2 on both sides
y = -7/2x - 8/2
y = -7/2x - 4
now we can plus in any x and y values to get a new b, which is our y intercept.
lets use (4,3)
Also, since they are parallel, their slope (m) will be the same.
y = -7/2x + b
3 = -7/2(4) + b
3 = -14 + b
b = 17
lets plug in our new b into our original equation
y = -7/2x + 17
The value of [y] = 7 and that of [x] = 6.
What is the general equation of a Straight line?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written to express proportional relationship as -
y = kx {k is constant}
We have a equation that represents a line as -
7x + 2y = - 8
We can write -
7x + 2y = - 8
2y = - 7x - 8
y = (-7/2)x - 4
Options are not given, so the line whose slope will be (-7/2) will be parallel to the given line with equation 7x + 2y = - 8
Therefore, line whose slope will be (-7/2) will be parallel to the given line with equation 7x + 2y = - 8

The text message component of each of Juan's monthly phone bills consists of $10.00 for the first 300 text messages sent that month, plus $0.10 for each additional text message sent that month. On Juan's most recent phone bill he was charged a total of $16.50 for text messages. For how many text messages in total was Juan charged on this bill?
Answer:
365 messages
Step-by-step explanation:
x = # text messages)
16.5 = 10 + .10(x - 300)
6.5 = .10x - 30
36.5 = .10x
x = 365
Answer:
365
300+65=365 text messages in total
365 text messages=$16.50
Step-by-step explanation:
6.50/0.10=65

size of the sample. By doing so:
O nonresponse will be eliminated.
the results of the sample will be unbiased.
the variability of the sample results will be reduced, giving greater precision in the estimate.
the pollster can be certain that he can correctly predict the outcome of the election.

Scientists tagged 950 pike for a research project about a local lake. Later, they trapped 100 pike, of which 10 had tags. To the nearest whole number, what is the best estimate for the pike population?
Answer:
9500
Step-by-step explanation:
Scientists tagged 950 pike for a research project about a local lake. Later, they trapped 100 pike, of which 10 had tags. To the nearest whole number, what is the best estimate for the pike population?
The best estimate of a population is calculated as:
= N = mn/k
Where N = Estimate of the population
m = 950 pike
n = 100 pike
k = 10 tags
= 950 × 100/10
= 9500
The best estimate of he population = 9500

two angles are supplementary. the bigger angle is three times as large as the smaller angle.find the measurement of the angles
Answer:
The bigger angle is 135, and the smaller angle is 45.
Step-by-step explanation:
First, you have to know that supplementary angles add up to 180°.
We have no equations for the angles, so I will use the variable x for the value of the smaller x.
The reason for this: the problem gave the value of the bigger angle, but relative to the smaller angle. Therefore, it would be safe to assume the use of a variable for the smaller angle.
Since the bigger angle is 3 times as large as the smaller, we can say that the bigger angle is 3x, or 3 times x.
Now, we can put this in an equation: 3x+x=180. Like I said before, both of the angles add up to 180 degrees.
To solve the equation:
1. Combine like terms
4x=180
2. Divide both sides by 4
x=45
Now that we have the value of x, we can plug that in to 3x and x to find the angles.
3*45=135, which is the bigger angle
45, which is the smaller angle.

[tex] \frac{1}{6} \div \frac{2}{6} [/tex]
When dividing fractions you multiply by the reciprocal of the second fraction. Therefore your question changes to this:
[tex] \frac{1}{6} \times \frac{6}{2} [/tex]
You multiply as across as normal and you'll end up with
[tex] \frac{6}{12} [/tex]
Which when simplified gives you
