What is the slope of the line that goes through the points (1,-2) and (3,6)?

A.) -4


B.) 2


C.) 4


D.) 1

Answers

Answer 1

Answer:

(C).  4

Step-by-step explanation:

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\\\\\left(x_1,\:y_1\right)=\left(1,\:-2\right),\:\\\left(x_2,\:y_2\right)=\left(3,\:6\right)\\\\m=\frac{6-\left(-2\right)}{3-1}\\\\m = \frac{6+2}{3-1}\\ \\m = \frac{8}{2} \\\\Simplify\\\\Slope = m = 4[/tex]

how do you combine like terms​

Answers

Answer: you add them up

Step-by-step explanation:

Explanation:

Combining like terms is commonly used to solve algebraic expressions. Like terms are those species or variables that are the same in any algebraic representation.

  Different mathematical operations can be performed on like species. We can add, divide, multiply, subtract, factorize, etc those terms.

Take for example;

   Solve;

        5x + 3  = 4x + 6

To solve this simply collect the like terms;

     5x  and 4x, 3 and 6 are like terms

       5x - 4x  = 6 - 3

        x  = 3

This is one way of solving problems by collecting like terms.

Answers

Answer:

y= -7/8x – 1

Step-by-step explanation:

the first equation would be y= 8/7 + 6/7the perpendicular slope would be -8/7and I solved for b by plugging in what I know for y=mx+bwhich is 6= -7/8(-8) + bsimplify so 6 = 7 + bsubtract 7 on both sides to get b = -1

2. One action figure sells for $3.50 How many action figures can Sergio buy for $20.00?​

Answers

Answer:

He can buy 5

Step-by-step explanation:

To find the answer, you have to do divide 3.50 and 20. You get 5.714285714. You can't round up, since you are dealing with money, so round down to 5.

Hope this helps :)

Step-by-step explanation:

One action figure can be shown as x so x=$3.50.

Sergio has $20.00 so the equation is 20.00÷3.50 = number of x's Sergio can buy.

20÷3.50 =5 2.5/3.5

So x=5 2.5/3.5

Tran earns $16 per hour and is paid a flat fee of $46 each week. At

equation y=16x + 46, where x is the number of hours, and y is the
total weekly salary. Write this relationship in functional notation, as a
function S(h), where S(h) represents the salary for h number of hours.

Answers

Answer:

[tex]S(h)=16h+46[/tex]

Step-by-step explanation:

We just need to substitute the variables here! You already have the equations so instead of [tex]x[/tex] for hours, we use [tex]h.[/tex] And since it's a function the result is not [tex]y[/tex] but rather [tex]S(h)[/tex].

What is vertex form of a quadratic equation?

The vertex form of a quadratic equation or function is [tex]f(x)=a(x-h)^{2} +k[/tex].

Where,

(h, k ) is the vertex

And, a is constant.

According to the given question

We have a quadratic function

[tex]f(x) = x^{2} + 6x + 9[/tex]

The above function can be written as  

[tex]f(x) = x^{2} +2(3x) +9[/tex]

⇒[tex]f(x) = x^{2} + 2(3x) + (3^{2}) -(3)^{2} + 9[/tex]

⇒[tex]f(x) = (x+3)^{2} -9+9[/tex]

⇒[tex]f(x) = (x+3)^{2} + 0[/tex]

Comparing the above equation with the standard  vertex form of quadratic function we get

h = -3 and k = 0

Hence, the vertex of the given quadratic function is (-3, 0).

Thus, option A is correct.

Answers

Okay, so first we need to work out the gradient, m.

To do this use the formula change in y/ change in x

So If we pick two points, say 0,-3 and -4,-5 the change in y is from -3 to -5 so it is -2 and the change in x is from 0 to -4 so is taking away 4 so the gradient is -2/-4 which is 1/2.

Then we need to work out the y intercept, c.

Substitute the gradient into y= Mx+ c to get y = 1/2 x + c. Use a point to substitute in and solve:

Eg 4, -1 —> -1 = 1/2 x 4 + c
Then -1 = 2 + c
Then -3 = c
So you get the end equation of

Y = 1/2x -3
