The system of equations has two solutions, these are:

(-0.89, 2.33) and (1.4, 9.2)

Here we have the following system of equations:

y = 3x + 5

y = 4x² + x

We can see that y is already isolated in both equations, so we can write the equation:

3x + 5 = y = 4x² + x

3x + 5 = 4x² + x

now we can solve this for x, this is just a quadratic equation:

3x + 5 - 4x² - x = 0

-4x² + 2x + 5 = 0

Using the quadratic formula, we can see that the two solutions are:

[tex]x = \frac{-2 \pm \sqrt{2^2 - 4*(-4)*5} }{2*-4} \\\\x = \frac{-2 \pm 9.17}{-8}[/tex]

So the solutions are:

x = (-2 +9.17)/-8 = -0.89

x = (-2 - 9.17)/-8 = 1.4

Evaluating the linear equation in these values, we get:

y = 3*(-0.89) +5 = 2.33

y = 3*(1.4) + 5 = 9.2

So the solutions of the system are:

(-0.89, 2.33) and (1.4, 9.2)

Step-by-step explanation:

a parallel line must have the same slope (otherwise it cannot be parallel).

a slope-intercept form looks like

y = ax + b

"a" (the factor of x) is always the slope, "b" is the y-intercept (the y-value when x = 0).

so, we know from y = -3x + 5 that the slope of the new line is also -3.

to get b we use the coordinates of the given point :

-5 = -3×-8 + b = 24 + b

-29 = b

that means the line equation is

y = -3x - 29

Answer:

Step-by-step explanation:

a. From 4 to 7 is 3 units. 7-10 is another 3 units and so on. The constant 3 units is the common difference.

The formula for a arithmetic sequence is

[tex]a_{n}=a_{1}+d(n-1)[/tex]

Where d is the common difference and a_1 is the first term.

[tex]a_{1}=4[/tex] and [tex]d=3[/tex]. Thus the equation of the nth term is

[tex]a_{n}=4+3(n-1)[/tex]

Step-by-step explanation:

Liability is money you owe to another person or institution, including a credit card balance, mortgage and so on.

So the plumber's liabilities

The difference of population in these two cities are 85900- 3200

= 82,700

Subtract the largest number from the lowest number to determine the difference between two integers. The difference between the two numbers is the product of this sum. As a result, there are 55 between the numbers 45 and 100.

Given: Population of city A= 8.59 x 10^4

and population of city B = 3.2 x 10^3

This can also be written as :

Population of city A= 85,900

and population of city B = 3200

Thus the difference of population in these two cities are 85900- 3200

To find the probability that the mean IQ score of people in the sample is less than 98, first we need to convert the value into z-score by using the formula:

Then, when x=98:

By checking in a standard normal table z=-0.1333 has a p-value=0.4471.

Then the probability is 0.4471 that also can be expressed as 44.71%

The single inequality y > |x + 2| is equivalent to:

4. y > x + 2

y < –x – 2

It should be noted that an inequality is simply used to show the relationship between the expressions that aren't equal.

The non-negative value of a real number x, regardless of its sign, is its absolute value or modulus | x |. For instance, 5 has an absolute value of 5, and 5 has a value of 5. One way to think about a number's absolute value is as its distance from zero on the real number line.

It should be noted that based on the information, the inequality is:

y > |x + 2|. This is the positive part of the modulus.

This is the same as y < –x – 2 when the signs are changed. This is the negative part of the modulus.

In conclusion, the correct option is 4.

The 64 fluid ounces of water, as suggested by Kamryn's doctor to drink everyday, will be equal to 1920 millilitres.

Writing the equation as per the relation between millilitres and fluid ounces -

1 fluid ounce = 30 millilitres

Now, we will perform multiplication to find the number of milliliters in 64 fluid ounces. Writing the expression representing relation between millilitres and fluid ounces

Number of milliliters = 30×64

Performing multiplication between the numbers 30 and 64

Number of milliliters = 1920

Therefore, on drinking 64 fluid ounces by Kamryn on her doctor's recommendation will drink 1920 millilitres of water everyday.

Slope unit = Probability of winning/Rank

B) The y-intercept is the point at which the graph crosses the y-axis. In this case, it means no ranked school and that is the probability of winning for an unranked school.

C) The linear equation is given by the formula;

Therefore, the greatest number of file boxes that can be stacked is 12.

The x-intercept is (27,0). The time it takes to reach the bus stop

We first find the equation between time and distance as a linear function by finding the slope and y-intercept from the table values.

If we write the Time as x-values and Distance as y-values, we get the points,

(0,45), (3,40), (6,35), (9,30), (12,25)

We can find the slope from these points considering two points (0,45) and (3,40)

Slope = 45-40/0-3 = -5/3

The y-intercept of the function is the value of f(x) at x = 0.

Here, from the table, when x = 0, y = 45.

So y-intercept = 45

Then the equation of distance in terms of time is,

y = -(5/3)x+45

The x-intercept is the x-value when y = 0.

So when y = 0,

0 = -(5/3)x+45

⇒ (5/3)x=45

⇒ x = 45x 3/5

⇒ x = 27

Therefore, x-intercept = (27,0).

It is the time (in minutes) when distance = 0 meters.

So x-intercept is the time it takes to reach the bus stop.

Answer:

Step 3; it should be angle m + angle n + angle o = angle o + angle p

Step-by-step explanation:

yes, the sum of the inner angles of the triangle, m, n, o must be 180°.

yes, the sum of supplementary angles (which the pair of inner and outer angles always is) p and o must be 180°.

so, step 3 wants to show that the sum of the 3 inner angles is the same as the sum of the inner/outer angle pair. m + n + o = o + p = 180.

but instead of o the student suddenly wrote n in the right side of the equation. and that is wrong. n + p can't be 180°, as both are inner angles, and that would make the third inner angle 0°, which is not really possible.

so, once n is replaced by o on the right side of the equating in step 3, all is correct again.

and step 4 is correct anyway (it fixed the mistake in step 3 of the original proof by another mistake, coming to the right conclusion just by coincidence), now that step 3 is corrected.

The number line having -2.4 and -2.8 is attached below

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. We refer to these as closed number lines. Number lines may alternatively be left empty or blank. A number ladder is a vertical number line.

Given number: −12/5 and –2.8

As, we can write -12/5 in decimal form= -2.4

For the rectangle given, considering its diagonal properties, the value of x=4, while the angle VUR=36°

To answer this question, let us recall the following:

Hence;

the lengths RV and SV are

so, 3x+8=6x-4

6x-3x=8+4 [collecting like terms]

3x=12

when we divide both sides of the equation by 3, we have the value of x=4.

the angles VRS and VRU are complementary

so, 54°+VRU = 90°

VRU = 90°-54°

VRU = 36°

The triangle RUV is an Isosceles

so, angles VRU and VUR are equal, therefore angle VUR = 36°.

We can reduce from our workings that the value of x = 4 and the angle VUR is 36°.
