[tex]\frac{-8}{5}[/tex]

Step-by-step explanation:

Slope is the change in y over the change in x

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

(-2,4) is ([tex]x_{1}[/tex], [tex]y_{1}[/tex])

(3. -4) is ([tex]x_{2}[/tex],[tex]y_{2}[/tex])

[tex]\frac{-4 - 4}{3 - -2}[/tex] = [tex]\frac{-8}{3+ 2}[/tex] = [tex]\frac{-8}{5}[/tex]

Answer:

-8 / 5

Step-by-step explanation:

We can use the slope formula

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

    = ( -4 -4)/( 3 - -2)

   = -8/ ( 3+2)

   = -8 / 5

x ≥ –3; y ≥ x – 2

x > –3; 5y ≥ –4x – 10

x > –3; y ≥ –x + 1

x > –2; y ≥ –x – 1

n > 39/4 is value of quartic equation.

What does quartic equation mean?

A fourth-degree equation, often known as a quartic equation, is one that reduces a quartic polynomial to zero and has the formula: where a 0. A quartic function's derivative is a cubic function.

For a quadratic ax² + bx +c , the sign of its determinant, given by

 Δ = b²- 4ac

"determines" the nature of its roots. In particular, if Δ<0 , then the quadratic has two distinct non-real roots.

Now, we have

3z² - 9z = n - 3

3z² - 9z - (n - 3)  = 0

with determinant

Δ = (-9)² - 4 .3( n - 3 ) = 117 - 12n

Solve for  such that Δ < 0

Δ = 117 - 12n < 0 ⇒  12n > 117

n > 117/12

Answer:

Step-by-step explanation:

The triangles are congruent because they follow the SSS triangle congruence postulate. As the SSS postulate says that all 3 sides of one triangle are congruent to another triangle's sides, these triangles shown have all three of their sides congruent to each other.

Answer: I am no sure but the only way to decide whether a pair of triangles are congruent would be to measure all of the sides and angles, and these triangles do not look the same so I would say that these tringles are not congruent.

Step-by-step explanation:

The value of (x) that satisfy the equation → - 3 - 23x = - 14(x - 21) - 15(x + 33) is x = - 33.

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.

Given is the following equation -

- 3 - 23x = - 14(x - 21) - 15(x + 33)

The given equation is -

- 3 - 23x = - 14(x - 21) - 15(x + 33)

Simplifying for (x), we get -

- 3 - 23x = - 14x + 294 - 15x - 495

- 23x + 14x + 15x = 3 + 294 - 495

6x = - 198

x = - 33

Therefore, the value of (x) that satisfy the equation → - 3 - 23x = - 14(x - 21) - 15(x + 33) is x = - 33.

The equation of the axis of symmetry is x = 2

The equation of the axis of symmetry is the value of x that divides the parabola into equal halves (mirror images).

The value of x which gives the mirror images is the value of x coordinate of the vertex. The vertex is at (2, 0). The x coordinate = 2

From the graph, we can also see it occurred at x = 2

The axis of symmetry: x = x-coordinate of the vertex

The equation of the axis of symmetry is x = 2

Explanation:

Given the function:

First, we find the vertex of the parabola.

Vertex

The equation of the axis of symmetry is calculated using the formula:

From the function: a=2, b=-12

Substitute x=3 into y to find the y-coordinate at the vertex.

The vertex is at (3, -3).

Two points to the left of the vertex

When x=2

When x=1

Two points to the right of the vertex

When x=4

When x=5

Answer:

Plot these points on the graph: (3, -3), (2,-1), (1,5), (4,-1), and (5,5).

Since y is a parabolla, there will be two values for y = 19. We already know that x = 1 is one value, to find the other, we can substitute y = 19 on the equation and solve for x to get the following:

the solutions of the equation are x = 1 and x = -7. Since we already have that (1,19) is a point on the graph, then we have that the other point is (-7,19)

The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle m∠K is 102° so option (B) is correct.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are 3 sides and three angles in every triangle, some of which may be the same.

Triangle is a very common figure to deal with in our daily life.

It is known that the sum of all three angles inside a triangle will be 180°.

So,   m∠A +  m∠B +  m∠C = 180°

m∠C = 180° - 58° -  44°

m∠C = 78°.

The exterior angle of C = 180- 78 = 102°.

Hence "The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to m∠K is 102°".

The desired monthly yield at the retirement time will be equal to $565,714.28.

Compound Interest may be defined as the interest earned by the bank on the basis of principle and also accumulated interest which increases exponentially and not linearly with respect to time. In calculating compound interest, the amount earned at the end of first year becomes principle for the next year and so on. Compound interest can be calculated, annually, half-yearly or quarterly etc.

Time for which work is planned = 40 years, Principle = $4500 and APR = 8.4% = 0.084/12 = 0.007.

The value of n = 12 × 25 = 300

The amount can be calculated by the formula A = P/r [1 - (1 + r) ⁻ⁿ]

A = (4500/0.007) [1 - (1 + 0.007) ⁻³⁰⁰]

A = 642,857.14 [1 - 0.12]

A = 642,857.14 × 0.88

To solve this problem, we will use the two pair of points to find the slope of the equation of each line. Then, by comparing these slopes, we can determine either if they are perpendicular or parallel.

Slope calculations

To calcula the slopes, given the pairs of points, we are going to use the following formula: Given points (a,b) and (c,d) the slope of the line that passes through them is given by the formula

Let us calculate first the slope of the line that passes through the points (7,5) and (-14,-9). In this case, we have a=7,b=5,c=-14 and d=-9. So we get

Now, let us calculate the slope of the line that passes through the points (0,1) and (4,-5). In this case, we have a=0,b=1,c=4 and d=-5. So we get

Slope comparison

Now, we compare the slopes to determine if the lines are perpendicular or parallel. Recall that two lines are parallel if they have the same slope and they are perpendicular if the product of their slopes is -1. From our calculations, we can see that the slopes are not equal. Let us confirm that they are perpendicular. To do so, we multiply both slopes. So we get

Since their product is -1, this confirms that both lines are perpendicular.

• x = 12

• y = 16

• z = 7

EXPLANATION

Because the triangles are similar, we have that:

• The ratio between corresponding sides is constant:

• Corresponding angles are congruent:

We know that the measure of angle E is 16°, so the measure of angle G must be the same because they are congruent,

With this equation, we can find x. First, divide both sides by 2,

And then, add 4 to both sides,

Hence, x = 12.

Now we know that the length of side EF is,

To find y and z, we will use the proportions we got at the top of this explanation,

Replace with the known values and the expressions with y and z,

With the first two, we can find z,

Simplify the right side,

Rise both sides to the exponent -1 - i.e. flip both sides of the equation,

Multiply both sides by 25,

Subtract 8 from both sides,

And divide both sides by 6,

Hence, z = 7.

Finally, with the last two proportions, we can find y,

The first two steps are the same we did to find z: simplify the left side and flip both sides,

Multiply both sides by 24,

And divide both sides by 3,

Hence, y = 16.
