since the triangle has parallel lines running through the angles equal the same for the triangle so finding x was just 180 - y+z =x

Answer:

I really want points because I'm struggling with a lot of homework

Answer:

A

Step-by-step explanation:

For functions with x in the denominator we want to make sure the denominator isn't 0. If x can't be -2 then the answer is A because x = -2 results in f(x) = 1/0 which is undefined.

The answer is 2.

Answer:

Step-by-step explanation:

Any multiple of the given equation is also a dependent linear equation

From the equation

-5x+7y=2

Multiplying all through by any number, say 2

2(-5x)+2(7y)=2(2)

-10x+14y=4 is a dependent linear equation for -5x+7y=2

If you don't fancy using a multiple, you can write the gradient equation y=mx+c

-5x+7y=2

7y=5x+2

Dividing all through by 7 gives the equation as

y=5x/7 + 2/7

Answer:

here is the answer

Step-by-step explanation:

(x + y, x - y)= (4,2)

therefore, x + y= 4 and x - y = 2

equating

x +y =4

x= 4-y

substituting

x - y= 2

(4-y)-y=2

4-2y=2

4-2=2y

2=2y

2/2=y

1=y

therefore,

x + y=4

x + 1=4

x= 4 - 1

x=3

verifying

3 + 1=4

4=4

3 - 1=2

2=2

Quotient=3x^2+2x+2

Remainder=8

Answer:

The equation in Slope-intercept form:

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

Step-by-step explanation:

-Find the slope first, by using the slope formula:

[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

(where [tex](x_{1},y_{1})[/tex] is the first point and [tex](x_{2},y_{2})[/tex] is the second point).

-Use two given points  from the following problem for the slope formula:

[tex]m = \frac{6-2}{6-0}[/tex]

-Then, solve the equation:

[tex]m = \frac{6-2}{6-0}[/tex]

[tex]m = \frac{2}{3}[/tex]

After you have the found the slope, use both the slope [tex]\frac{2}{3}[/tex] and the first point [tex](0,2)[/tex] for the Point-slope formula:

[tex]y - y_{1} = m (x-x_{1})[/tex]

(where [tex]m[/tex] is the slope and [tex](x_{1}, y_{1})[/tex] is the first point).

-The equation in Point-slope form:

[tex]y - 2 = \frac{2}{3} (x-0)[/tex]

Then, you solve:

[tex]y - 2 = \frac{2}{3} (x-0)[/tex]

[tex]y - 2 + 2= \frac{2}{3} (x-0) + 2[/tex]

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

-So, the equation in Slope-intercept form would be:

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

The equation of the line is y = 2x/3 + 2 if the line that passes through (0, 2) and (6, 6).

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The line that passes through (0, 2) and (6, 6)

The slope-intercept form of the equation:

Slope of the line = (6-2)/(6-0)

The slope of the line = 2/3

The equation of the line:

y = 2x/3 + 2

Thus, the equation of the line is y = 2x/3 + 2 if the line passes through (0, 2) and (6, 6).

Answer:

A recursive formula always uses the preceding term to define the next term of the sequence. Sequences can have the same formula but because they start with a different number, they are different patterns.

Answer:

[tex]3(x - 7)(x+7)[/tex]

Step-by-step explanation:

To factor this, you must first take out the GCF (Greatest Common Factor), that [tex]3x^2[/tex] and -147 both have. The terms only have 3 in common, which can be divided with

[tex]3x^2 - 147\\3(x^2 - 49)[/tex]

However, we're still not done since 49 is a perfect square and [tex](x^2 - 49)[/tex] can be split into 2, like so:

[tex]3(x - 7)(x+7)[/tex]

If you're unsure about the final answer, you can multiply it all together to see if you got the original expression.

Line S and Line Q

Step-by-step explanation: Line S and Q would form a pair of perpendicular lines because perpendicular lines form a 90 degree angle.

A pair of perpendicular lines in the given figure are line q and line s.

Those lines that are perpendicular to each other that means create an angle of 90° at intersecting point are perpendicular lines.

Given:

There are 4 lines in the diagram.

To find the pair of perpendicular lines:

Those lines that are perpendicular to each other that means create an angle of 90° at intersecting point are perpendicular lines.

And line q is perpendicular to line s.

Therefore, line q is perpendicular to line s.

Answer:

F = P(1 - x)^n

F = 10,000(1 - 0.1)^7

F = 10,000(0.9)^7

F = $4,783

The value of the tractor in 7 years is $4,783

Step-by-step explanation:

Applying the exponential depreciation equation;

F = P(1 - x)^n

Where;

F = final value after n years

P = initial value

x = depreciation rate (fraction)

n = time

Given;

P = $10,000

x = 10% = 0.10

n = 7 years

Substituting the given values;

F = 10,000(1 - 0.1)^7

F = 10,000(0.9)^7

F = 4782.969

F = $4,783

The value of the tractor in 7 years is $4,783

Answer:

$42

Step-by-step explanation:

The yearly membership is $450.

The monthly membership is $41. This means that in a year, the membership fee will be:

41 * 12 = $492

We have to subtract the yearly fee from this.

That means that if you choose the yearly membership over the monthly membership, you'll save:

492 - 459 = $42

Answer:

The correct answer is $42.

Answer:

y = 2/5x+2

Step-by-step explanation:

First find the slope

m = (y2-y1)/(x2-x1)

    = (4-2)/(5-0)

    =2/5

The y intercept is 2

The slope intercept form is y = mx+b

where m is the slope and b is the y intercept

y = 2/5x+2

Answer:

y = mx + c

1) find the gradient, m

[tex]m = \frac{4 - 2}{5 - 0} [/tex]

[tex]m = \frac{2}{5} [/tex]

2) find value of y-intercept, c

from the graph, c = 2

2) use the formula y=mx+c

y = mx + c

y = 2/5x + 2

Step-by-step explanation:

Let the number of fancy throw pillows be x.

Let the number of plain throw pillows be y.

Hope spent a total of $131 on 7 throw pillows.

Fancy throw pillows  cost $28 and plain throw pillows cost $15.

These imply two things:

x + y = 7 _______  (1)

28x + 15y = 131 ___(2)

We have a linear system of equations.

From (1):

x = 7 - y

Substitute the value of f into (2):

28(7 - y) + 15y = 131

196 - 28y + 15y = 131

196 - 13y = 131

=> 13y = 196 - 131

13y = 65

y = 65 / 13

y = 5

This means that:

x = 7 - 5 = 2

Answer:

A. x = 24

B. x = 20

Step-by-step explanation:

→A. Add 2 to both sides:

[tex]\frac{x}{3} -2=6[/tex]

[tex]\frac{x}{3} =8[/tex]

→The fraction [tex]\frac{x}{3}[/tex] is really just [tex]\frac{1}{3}x[/tex]:

→Multiply 3 to both sides:

x = 24

→B. Subtract 1 from both sides:

[tex]\frac{x}{5} +1=5[/tex]

[tex]\frac{x}{5} =4[/tex]

The fraction [tex]\frac{x}5}[/tex] is really just [tex]\frac{1}{5}x[/tex]:

→Multiply 5 to both sides:

x = 20

Let's solve for f.

9xyf=87

Step 1: Divide both sides by 9xy.

9fxy / 9xy  =  87 / 9xy

Description:

Since we are solving for f. Step 1 is to divide both sides by 9xy. That the only step to do. After you divide you answer will come as...

Answer:

The probability is 0.0069

Step-by-step explanation:

First thing to do here is to calculate the z-score

Mathematically;

z-score = (x-mean)/SD/√(n)

where x = 9.1 , mean = 8.4 , SD = 1.8 and n = 40

Plugging these values into the z-score equation, we have;

z-score = (9.1-8.4)/1.8/√(40) = 0.7/1.8/6.325 = 0.0615

Now, we check the standard normal table for P(z > 2.46) = 0.0069
