[tex]\large\boxed{y=\dfrac{2}{3}x+4}[/tex]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept (0, b)

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points:

(0, 4) → y-intercept (b = 4)

(3, 6)

Substitute:

[tex]m=\dfrac{6-4}{3-0}=\dfrac{2}{3}[/tex]

Finally we have the equation:

[tex]y=\dfrac{2}{3}x+4[/tex]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (0, 4) ← 2 points on the line

m = [tex]\frac{4-2}{0+3}[/tex] = [tex]\frac{2}{3}[/tex]

note the line crosses the y- axis at (0, 4) ⇒ c = 4, hence

y = [tex]\frac{2}{3}[/tex] x + 4 ← in slope- intercept form

OR

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = [tex]\frac{2}{3}[/tex] and (a, b) = (3, 6), hence

y - 6 = [tex]\frac{2}{3}[/tex](x - 3) ← in point- slope form

Answer:

f(5) = 6(5 - 2) = 6(3) = 18

Step-by-step explanation:

You're asked to "evaluate" f(x)=6(x-2) when x = 5.

To do this, replace both instances of x with 5:  f(5) = 6(5 - 2) = 6(3) = 18

Answer:

Hence, the value of the function for f(5) is 18..

Step-by-step explanation:

Consider the provided function.

[tex]f(x)=6(x-2)[/tex]

We need to find the value of function at x = 5.

Substitute x = 5 in above function and simplify.

[tex]f(5)=6(5-2)[/tex]

[tex]f(5)=6(3)[/tex]

[tex]f(5)=18[/tex]

Hence, the value of the function for f(5) is 18.

Answer:

The slope is 4 and the y-intercept is 12.

Answer:

The slope is 4, and the y-intercept is 12.

Step-by-step explanation:

In the given graph consider to coordinates of line:

(-3,0), (-2,4)

Slope of the of line can be calculated by using formula:

[tex](x_1,y_1) , (x_2,y_2)[/tex]

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{4-0}{-2-(-3)}=\frac{4}{1}=4[/tex]

And the equation of the line can be given as:

[tex](y-y_1)=m(x-x_1)[/tex]

m = slope of the line

[tex](y-0)=4\times (x-(-3)[/tex]

[tex]y=4x+12[/tex]

Slope intercept form of line:

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

c = intercept on y axis

On comparing equation line with slope intercept form

y=4x+12

y=mx+c

m = 4, c = 12

The slope is 4, and the y-intercept is 12.

Answer:line a would have a y intercept of three and a slope of 1/2. Line b would have a y intercept of negative one and a slope of 3/2

Step-by-step explanation:line a would start at 3 on the y axis and move up one to the right two. Line b would start at -1 on The y axis and move up three to the right two

The system of equations y=1/2x + 3 and y= 3/2x -1 can be represented as two lines on a graph, the intersection of which indicates any common solution.

The system y=1/2x + 3 and y= 3/2x -1 represents two linear equations. These two equations can be graphed out onto the x and y-axis. The first equation y=1/2x + 3 will have a slope of 1/2 and y-intercept of 3, and the second equation y= 3/2x -1 will have a slope of 3/2 and y-intercept of -1.

To graph the first equation, start at the point (0,3) on the y-axis. From there, as the slope is 1/2, for every 2 units you move to the right on the x-axis, you will move 1 unit up on the y-axis.

To graph the second equation, start at the point (0,-1) on the y-axis. As the slope is 3/2, for every 2 units you move to the right on the x-axis, you will move 3 units up on the y-axis.

These lines intersect at their solution, if one exists, that is a common point on both lines.

Area is in square units.

Square the scale factor: 4^2 = 16

The area is 16 times the original area.

Answer:

81 degrees

Step-by-step explanation:

A quadrilateral has four interior angles which sum up to 360 degrees.

As we are given that two angles are right angles which means the sum of two angles will be 180 degrees and the third angle is 99 degrees.

As we know that the four angles sum up to 360 degrees.

Let A,B,C and D denote the four angles,

Then

Sum of angles = 360

A+B+C+D=360

90+90+99+D=360

279+D=360

D=360-279

D= 81 degrees

So the fourth angle is 81 degrees ..

Hello!

The first step you would want to do here is distribute the -3 to inside the parentheses. This can be done by multiplying -3 by what's inside the parentheses. This would make the original equation become:

y + 1 = -3(x - 5)

y + 1 = (-3 * x) - (5 * -3)

Then, complete the multiplication inside the parentheses to get:

y + 1 = -3x + 15

Now, subtract both sides by 1 to isolate the y on the left side.

y + 1 - 1 = -3x + 15 - 1

Therefore, your final answer is:

y = -3x + 14

(it can also be f(x) = -3x + 14, y and f(x) are the same thing in this case)

Hope this helped!

Answer:

subtraction property of equality

Step-by-step explanation:

The equation in the question is incomplete, the complete equation is:

5 + x = 2

To solve this equation we have to use the subtraction property of equality, that is, if you subtract some number at both sides of the equal sign, the equation doesn't change. So:

5 + x - 5 = 2 - 5 (You must select a number which isolate x)

x = -3

Answer:

y = 4[2]^x

Step-by-step explanation:

One possible model for this function is the exponential y = a(b)^(kx).  Notice that if x = 0, y = a, and so, from the graph, we see that a = 4.

Then we have the exponential y = 4(b)^(kx).  Substitute 8 for y and 1 for x:

8 = 4(b)^(k), or 2 = b^k.

Then y = a(b)^(kx) becomes y = 4(b)^(kx) = 4[b^k]^x = 4[2]^x = y

The desired function is y = 4[2]^x.

Check this out.  Does the point (0, 4) satisfy this function?

Is 4 = 4[2]^0 true?  YES, it is.

Is 8 = 4[2]^1 true?  Is 8 = 4(2) true?  YES, it is

Four popular derivative notations include: The Leibniz notation, which has a d/dx format. The Lagrange notation, characterized by prime notation. The Euler notation, where a capital D is used.

It's just a different notation to express the same thing. On the other hand, if you want to represent the set with interval notation, you need to know the upper and lower bound of the set, or possibly the upper and lower bound of all the intervals that compose the set.

An equation involving x and y, which is also a function, can be written in the form y = “some expression involving x”; that is, y = f ( x). This last expression is read as “ y equals f of x” and means that y is a function of x.

[tex]y=2(x+\dfrac{7}{2})^2+\dfrac{1}{2}[/tex]

Answer:

B

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given

y = (x + 3)² + (x + 4)² ← expand and simplify

  = x² + 6x + 9 + x² + 8x + 16

  = 2x² + 14x + 25

To obtain vertex form use the method of completing the square

The coefficient of the x² term must be 1

Factor out 2 from 2x² + 14x

y = 2(x² + 7x) + 25

add/ subtract ( half the coefficient of the x- term )² to x² + 7x

y = 2(x² + 2([tex]\frac{7}{2}[/tex]) x + [tex]\frac{49}{4}[/tex] - [tex]\frac{49}{4}[/tex] ) + 25

y = 2(x + [tex]\frac{7}{2}[/tex] )² - [tex]\frac{49}{2}[/tex] + [tex]\frac{50}{2}[/tex]

A Is the correct answer ( y = 2x - 4 )

Step-by-step explanation:

The answers listed are provided in Y= Mx + B. What this means is M = Slope and B = Y Intercept.  The Y-Intercept is where the imaginary line crosses the Y axis of the graph or where x = 0. In this case the Y-Int is -4 and the slope of the graph is 2 over 1 ( A rise of two and a run of one ) in other terms it's just 2, but once you put this into the equation y = Mx + B it becomes 2x. Your final product would be y = 2x - 4

Evelyn can serve nine friends with her three apples if she gives each friend 1/3 of an apple by performing a simple multiplication of the number of apples, which is 3, by the reciprocal of 1/3.

Evelyn has three apples and wants to serve each friend 1/3 of a whole apple. To find out how many friends she can serve, we must divide the total number of apples (which is 3) by the fraction each friend receives (which is 1/3).

We perform the division by multiplying the total number of apples by the reciprocal of 1/3, which is 3. So, 3 apples x3 gives us 9. Therefore, Evelyn can serve nine friends.

Understanding fractions can be made easier by relating them to everyday examples. Say, if you have a whole pie, then one-third of this pie represents a slice that is one out of three equal parts of the pie. Knowing that four quarters make one dollar can also make it easy to grasp that four quarters (or four 1/4s) make a whole, just like four 1/4s of a pie would make a full pie.

Answer:

Out of the four, the only statement true about the parent and the transformed function is:

"The domain of the transformed function and the parent function are all real numbers."

Step-by-step explanation:

Parent function:

f(x) = |x|

Applying transformations:

1. Stretched by a factor of 0.3:

f(x) = 3|x|

2. Translated down 4 units:

f(x) = 3|x| - 4

Transformed function:

f(x) = 3|x| - 4

We can see that:

Range of the parent function = All real numbers greater than or equal to 0.

Range of the transformed function = All real numbers greater than or equal to -4.

Domain of the parent and the transformed function is same and equal to all real numbers.

Hence, the first three statements are wrong and the fourth one is true.

Answer:

The domain of the transformed function and the parent function are both all real numbers.

Step-by-step explanation:

Stretching a function by any factor doesn't change either its domain nor its range.

Translating up or down a function changes its range. In this case, the lowest value the parent function can take is 0 when x=0; after translation, for x = 0 then f(x) = -4. Therefore,

f(x) = |x|  

domain = all real numbers

range = [0, infinity)

f(x) = 0.3*|x| - 4

domain = all real numbers

range = [-4, infinity)
