Step-by-step explanation:

Answer:

x = -6 and x = 1

Step-by-step explanation:

Move everything to the left side of the equation by subtracting (-10x + 12)

2x² = -10x + 12

2x² + 10x - 12 = 0

Divide each side by 2:

x² + 5x - 6

Find 2 factors of -6 that add up to 5. These factors are 6 and -1

x² + 5x - 6

(x + 6)(x - 1)

Set this equal to 0 and solve for x

(x + 6)(x - 1)

x + 6 = 0

x = -6

x - 1 = 0

x = 1

So, the solutions to the equation are x = -6 and x = 1

The solutions to the equation 2x² = -10x + 12 are x = -6 and x = 1.

To find the solutions to the quadratic equation 2x² = -10x + 12, we can rearrange the equation into standard quadratic form, which is ax² + bx + c = 0.

First, we move all the terms to one side of the equation:

2x² + 10x - 12 = 0

Next, we can solve this equation by factoring, completing the square, or using the quadratic formula. In this case, we'll use factoring.

Looking at the equation, we notice that all coefficients are even, so we can simplify the equation by dividing both sides by 2:

x² + 5x - 6 = 0

Now, we factor the quadratic expression:

(x + 6)(x - 1) = 0

By setting each factor equal to zero, we can find the solutions:

x + 6 = 0 --> x = -6

x - 1 = 0 --> x = 1

Therefore, the solutions to the equation 2x² = -10x + 12 are x = -6 and x = 1. These values make the equation true when substituted back into the original equation.

Answer:

Given:

x is a factor of y --> , for some non-zero integer ;

y is a factor of z --> , for some non-zero integer ;

So, .

Question: is z even? Note that will be even if either or is even

(1) even --> either even, so the answer is directly YES or is even (or both). But if is even and as then z must be even too (one of the multiples of z is even, so z is even too). Sufficient.

(2) even --> as then as one of the multiples of z even --> z even. Sufficient.

Answer:

The equation of the circle is [tex](x + 1)^2 + y^2 = 25[/tex]

Step-by-step explanation:

Equation of a circle:

The equation of a circle of centre [tex](x_c,y_c)[/tex] has the following format:

[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]

In which r is the radius.

Center (-1,0)

This means that [tex]x_c = -1, y_c = 0[/tex]. So

[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]

[tex](x - (-1))^2 + (y - 0)^2 = r^2[/tex]

[tex](x + 1)^2 + y^2 = r^2[/tex]

Finding the radius:

Distance between the radius and the centre and a point of the circle. In this case, point (2,-4). Using the formula for the distance between two points:

[tex]r = \sqrt{(2-(-1))^2+(-4-0)^2} = \sqrt{3^2 + 4^2} = \sqrt{25} = 5[/tex]

So, the equation of the circle is:

[tex](x + 1)^2 + y^2 = 5^2[/tex]

[tex](x + 1)^2 + y^2 = 25[/tex]

Answer:

The vertex of a parabola is (h,k)

Step-by-step explanation:

The vertex form of a parabola is y=a(x-h)^2+k where a is the stretch/compression factor and (h,k) is the vertex. So to find the vertex, you will need (h,k) which represents the horizontal and vertical shift of the parabola

Step-by-step explanation:

i dont wanna explain but the answer is 4

For 0<x<4, the average rate of change will be -60

For 4<x<8 the the average rate of change will be -31

And for the sentence (on savass in order is)

Stay negative, -31, decrease but at a slower rate

In this exercise we have to use the knowledge of functions to describe the average rates of each one of them, so:

For 0<x<4 will be -60

For 4<x<8 will be -31

First, we have to remember what an average rate means, like:

So we can say that:

Answer:

x = 5/2 km/h

Step-by-step explanation:

Lets x be the speed of the current

The sea lion's speed with the current: 15 + x

The sea lion's speed against the current: 15 - x

Total distance in km with the current: 35

Total distance in km against the current: 25

Time with the current: 35/(15 + x)

Time against the current: 25/(15 - x)

So we do...

35/(15 + x) - 25/(15 - x) = 0

35(15 - x)/(15 + x) - 25(15 + x)/(15 - x): Having common denominators which is (15 + x)(15 - x)

525 - 35x - 375 - 25x = 0: Mutipling the (15 + x)(15 - x)to 0 getting 0

150 - 60x = 0

30(5 - 2x) = 0

x = 5/2

The speed of the current is 2.5 km/hr

From the given information

Lets x be the speed of the current

Also, we have that;

Total distance in km with the current to be 35 while the total distance in km against the current is 25

mathematically;

Time with the current = 35/(15 + x)

Time against the current =  25/(15 - x)

Equating both expression to get the value of "x

35/(15 + x) = 25/(15 - x) = 0

35/(15 + x) - 25/(15 - x) = 0

35(15 - x)/(15 + x) - 25(15 + x)/(15 - x)

Mutiplying the (15 + x)(15 - x)to have:

150 - 60x = 0

30(5 - 2x) = 0

x = 5/2

x = 2.5

Hence the speed of the current is 2.5 km/hr
