What is the x-intercepts of the graph of y = 12x-5x-2

Answers

Answer 1

Hey there!

First, we see that it's already written in slope intercept, y = mx + b where m is the slope and b is the y intercept, we just need to simplify the like terms on the right. We have:

y = 12x-5x-2
y = 7x - 2

Now that we have it in slope intercept form, whenever we have an x intercept, since it is crossing the x axis, there's no y value. We plug in 0 for y:

0 = 7x - 2
2 = 7x
2/7 = x

The x intercept is (2/7, 0)

Hope this helps!

To take out terms outside the radical we need to divide the power of the term by the index of the radical; the quotient will be the power of the term outside the radical, and the remainder will be the power of the term inside the radical.
First, lets factor 8:
[tex]8=2 ^{3} [/tex]
Now we can divide the power of the term, 3, by the index of the radical 2:
[tex] \frac{3}{2} [/tex] = 1 with a remainder of 1
Next, lets do the same for our second term [tex] x^{7} [/tex]:
[tex] \frac{7}{2} [/tex] = 3 with a remainder of 1
Again, lets do the same for our third term [tex]y^{8} [/tex]:
[tex] \frac{8}{2} =4[/tex] with no remainder, so this term will come out completely.

Finally, lets take our terms out of the radical:
[tex] \sqrt{8x^{7} y^{8} }= \sqrt{ 2^{3} x^{7} y^{8} } =2 x^{3} y^{4} \sqrt{2x} [/tex]

We can conclude that the correct answer is the third one.

First we rewrite the expression:

(8x ^ 7y ^ 8) ^ (1/2)

AB=2y+1, BC=y+1,CD=7x-3,DA=3x what is x and y

Answers

I attached the picture associated with this question.

Answer:
x = 2
y = 5

Explanation:
ABCD is a parallelogram. This means that each two opposite sides are equal.
This means that:
1- AB = CD
2y + 1 = 7x - 3 ...........> equation I
2- AD = BC
3x = y + 1
This can be rewritten as:
y = 3x - 1............> equation II

Substitute with equation II in equation I and solve for x as follows:
2y + 1 = 7x - 3 ...........> equation I
2(3x - 1) + 1 = 7x - 3
6x - 2 + 1 = 7x - 3
6x - 1 = 7x - 3
7x - 6x = -1 + 3
x = 2

Substitute with x in equation I to get y as follows:
y = 3x - 1
y = 3(2) - 1
y = 6 - 1
y = 5

Given the segments of a quadrilateral, the steps show that for it to be closed, the expression 3y + 10x + 1 = 0 must hold. Additional information would be needed to find unique values for x and y.

Given the segments AB, BC, CD, and DA of a quadrilateral:

AB = 2y + 1BC = y + 1CD = 7x - 3DA = 3x

For a quadrilateral to be closed, the perimeter equations must be equal. Thus, we set up the equality:

AB + BC + CD + DA = 0

Substituting the given segment expressions:

(2y + 1) + (y + 1) + (7x - 3) + (3x) = 0

Simplifying this equation:

3y + 4 + 10x - 3 = 0

Combine like terms:

3y + 10x + 1 = 0

This represents a linear equation involving x and y.

Assuming the quadrilateral is closed, another equation or condition is needed to solve for x and y simultaneously. If additional geometric or numeric information is provided about the quadrilateral, it can help solve the system.

What is the equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (−2, 4)? y = – x – 1y = – x + 5y = x – 1y = x + 5

Answers

the equation of the line parallel to 5x+2y=12 and passes through the point (-2, 4) is equal to y= -5/2x - 1

Answer: The required equation of the line is [tex] y=-\dfrac{5}{2}x-1.[/tex]

Step-by-step explanation: We are given to find the equation of the line that is parallel to the following line and passes through the point (-2, 4) :

[tex]5x+2y=12~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We know that

the slope-intercept form of the equation of a straight line is given by

[tex]y=mx+c,[/tex]

where m is the slope of the line.

From equation (i), we have

[tex]5x+2y=12\\\\\Rightarrow 2y=-5x+12\\\\\Rightarrow y=-\dfrac{5}{2}x+6.[/tex]

So, the slope of line (i) is given by

[tex]m=-\dfrac{5}{2}.[/tex]

We know that the slopes of two parallel lines are equal. So, the slope of the new line will be

[tex]m=-\dfrac{5}{2}.[/tex]

Since the line passes through the point (-2, 4), so its equation will be

[tex]y-4=m(x-(-2))\\\\\\\Rightarrow y-4=-\dfrac{5}{2}(x+2)\\\\\\\Rightarrow y-4=-\dfrac{5}{2}x-5+4\\\\\\\Rightarrow y=-\dfrac{5}{2}x-1.[/tex]

Thus, the required equation of the line is [tex] y=-\dfrac{5}{2}x-1.[/tex]

Answers

Answer:

arithmetic sequence; common difference is −40

Step-by-step explanation:

An arithmetic sequence is a sequence in which each term is found by adding a constant, called the common difference, to each previous term.

In this sequence, we go from 540 to 500 to 460, etc. Each time we are subtracting 40. This is the same as adding -40; this makes the sequence arithmetic.

The common difference of the arithmetic sequence will be negative 40. Then the correct option is A.

Find the unknown side length, x. Write your answer in simplest radical form.

Answer: The required value of x is 32.

Step-by-step explanation: We are given to find the length of the unknown side.

That is, x = ?

From the figure, we see a right-angled triangle with

length of the hypotenuse, h = 68 units,

length of the other two sides, a = 60 units and b = x.

Using Pythagoras theorem in the given right-angled triangle, we have

[tex]h^2=a^2+b^2\\\\\Rightarrow 68^2=60^2+x^2\\\\\Rightarrow x^2=68^2-60^2\\\\\Rightarrow x^2=4624-3600\\\\\Rightarrow x^2=1024\\\\\Rightarrow x=\pm32.[/tex]

Since x is the length of a side of the triangle, so it cannot be negative.

Therefore, x = 32 units.

Thus, the required value of x is 32.

The first team of workers received 50 kg of cement less than the second team. for every hour of work the first team was using 150 kg of cement, while the second team was using 200 kg. in three hours the first team had 1.5 times as much remaining cement as the second team. how much cement was delivered to each team of workers?

Answers

there are 2 unknown terms in this problem
the amount of cement the first team received is termed as 'x' hereafter
the cement the second team received is termed as 'y'
the first team received 50 kg less, the 1st equation is as follows;

x = y - 50 after rearranging
1) x-y = -50
for every hour 150 kg and 200 kg were used by the two teams separately
after three hours first team used up 150*3 = 450 kg
the second team used up 200 * 3 = 600 kg
however the first team had 1.5 times as much as second team had after three hours.
After three hours;
the amount second team had leftover was y - 600
the amount first team had leftover was x - 450
the amount the second team had ,multiplied by 1.5 is equal to what the first team had
we can build the 2nd equation using this information

1.5 * (y-600) = x-450
1.5y - 900 = x - 450
rearrange the equation,

1.5y - x = -450 +900
2) 1.5y - x = 450

add 1st and 2nd equations to eliminate x
1) + 2) (x - y = -50) + (1.5y - x = 450)
1.5y - y = 450 -50
0.5y = 400
y = 400/ 0.5
y = 800 kg
substitute y = 800 in x = y - 50
x = 800 - 50
x = 750 kg

first team received 750 kg and second team received 800 kg

A small plane is 20 miles due north of the airport. a jet at the same altitude as the plane is 64.5 miles west of the airport. to the nearest tenth, what is the distance between the small plane and the jet? enter your answer as a decimal in the box.

Answers

okay realize that the distance traveled by the small plane, distance traveled by jet, and the distance between them makes a right triangle. Using Pythagorean theorem and allowing x be the distance between them, x² = (20 miles)² + (64.5 miles
x = 67.53 miles the distance between the two entities in nearest tenth is approximately 67.5 miles.

Using the Pythagorean theorem, we can calculate the distance between a small plane 20 miles north of an airport and a jet 64.5 miles west of the airport as 67.5 miles to the nearest tenth.

Given that a small plane is 20 miles due north of the airport and a jet is 64.5 miles west of the airport, the scenario forms a right-angled triangle with the legs representing the distances from the airport to each aircraft. To find the distance between the small plane and the jet, we can use the Pythagorean theorem which states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides (the legs).

The equation for the distance (d) between the two planes can be expressed as:

d² = north side² + west side²

d² = 202 + 64.52

d² = 400 + 4160.25

d² = 4560.25

d = √4560.25

d = 67.5 miles (rounded to the nearest tenth)

Thus, the distance between the small plane and the jet is 67.5 miles to the nearest tenth.

Answer:

B. It is greater than -4 because 0.36*(7 5/8) is less than 1/2 * 8

Step-by-step explanation:

Given the question:

Which statement about this product is true? 0.36*(-7 5/8)

If you replace the multiplication:

0.36*(7 5/8)

1/2*8 = 4

You will get a greater result because 1/2 ( or 0.5) is greater than 0.36 and 8 is greater than (7 5/8). Taking into account that the original multiplication involves a negative number, then:

0.36*(7 5/8) < 1/2*8

0.36*(-7 5/8) > 1/2*(-8) (multiply by a negative number at both sides of the inequality change the sign)

In fact 0.36*(-7 5/8) = -2.745.
