Find the intercepts of the graph given the following equation 4x – 3y = 12

Answers

Answer:

y-intercept: -4 or (0, -4)

x-intercept: 3 or (3, 0)

Step-by-step explanation:

4x - 3y = 12

we can convert this to slope-intercept form (y = mx+b) given that m is the slope and b is the y-intercept

4x - 3y = 12

-3y = -4x + 12

y = 4/3x - 4

So the intercept is -4 or (0, -4).

For the x-intercept, we can make the y value 0 to solve for x.

4x - 3y = 12

4x - 3(0) = 12

4x = 12

x = 3

So the x-intercept is 3 or (3, 0).

Tran earns $16 per hour and is paid a flat fee of $46 each week. At
the end of the week her total salary can be represented by the
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].

So we get the answer of: [tex]S(h)=16h+46[/tex]

Can you find the equation of a line parallel to the green
line through the point (-5,-3). Write you equation in
point-slope form.

Answers

Answer:

[tex]\displaystyle y+3=-\frac{4}{5}(x+5)[/tex]

Step-by-step explanation:

The point-slope form of the equation of a line is:

y-k=m(x-h)

Where m is the slope and (h,k) is a point through which the line passes.

We are required to find the equation of the line passing through the point (-5,-3) and parallel to the green line shown in the graph.

We need to find the slope of the green line. Once we have the slope, we will have the slope of our line since parallel lines have the same slope.

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

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

We can clearly identify the following points in the green line: (0,4) (5,0):

[tex]\displaystyle m=\frac{0-4}{5-0}=-\frac{4}{5}[/tex]

Now we have the slope and the point, the equation of the line is:

[tex]\displaystyle y-(-3)=-\frac{4}{5}(x-(-5))[/tex]

[tex]\boxed{\displaystyle y+3=-\frac{4}{5}(x+5)}[/tex]

Answers

Step-by-step explanation:

Let's solve your equation step-by-step.

−5(x+7)=−5x+35

Step 1: Simplify both sides of the equation.

−5(x+7)=−5x+35

(−5)(x)+(−5)(7)=−5x+35(Distribute)

−5x+−35=−5x+35

−5x−35=−5x+35

Step 2: Add 5x to both sides.

−5x−35+5x=−5x+35+5x

−35=35

Step 3: Add 35 to both sides.

−35+35=35+35

0=70

Answer:

There are no solutions.

Answer:

x= no solution

Step-by-step explanation:

-5(x+7)=-5x+35

-5x-35=-5x+35

+5x       +5x

-35= 35

+35 +35

0=70

x=no solution

When x doesn't equal anything, and 0 doesn't equal 0, there is no solution to make the equation true. When 0=0, x can equal any value.

m = rise / run = -2/1 = -2

Arbitrarily choose the reference point (1, 0).  

Then y = mx + b becomes 0 = -2(1) + b, where b is the y-intercept.

The height of a building is 72 m. Find the angle of elevation from a point on ground level that is 55 m away from the base of the building

Answers

Answer:

52.6 degrees

Step-by-step explanation:

tan^-1(72/55)

Angle of elevation is equals to 52°7'(approximately).

What is angle of elevation?

" Angle of elevation is the angle between the horizontal plane and  line of sight from the point of observation."

Formula used

In a right angled triangle,

tanθ = ( opposite side) / adjacent side)

According to the question,

As shown in diagram

Height of the building (AB) = 72m

Distance between base of the building and point of observation

(BC)= 55m

Angle of elevation = θ

Substitute the value in the formula we have,

 tanθ = AB / BC

          = 72 / 55

⇒ θ = tan⁻¹ (72 /55)

      = tan ⁻¹(1.3091)

      = 52° 7' (approximately)

Hence, angle of elevation is equals to 52°7'(approximately).

Answer:

5) 52

6) $190.73

Step-by-step explanation:

5)

Let the unknown number be x.

40 is 77% of x

40 = 0.77x

Divide both sides by 0.77

x = 52

Answer: the number is 52.

6)

We first calculate the amount of tax which is 6.875% of $178.46.

6.875% of $178.46 =

= 0.06875 * $178.46

= $12.27

The amount of tax is $12.27.

Now we add the amount of tax to the price before tax.

$178.46 + $12.27 = $190.73

Which of the following graphs shows the solution set to t > 4 or t < -1?

Answers

Answer:

The second graph

Step-by-step explanation:

t is greater than 4 and less than -1 but doesn't include the points 4 and -1 (thus the open circles)

The second graph represents the solution set to t > 4 or t < -1.

What are open and closed interval ?

In open interval we do not include the point and represented by open circle in close interval we do include the points and represented by closed interval.

According to the given question we have to determine which graph represents the solution set t > 4 or t < -1.

We know when we represent less than or greater than in the number line we represent it as an open circle.

So, t > 4 will be represented by an open circle on the number line starting at 4  but not including which goes to positive infinity and t < -1 will be represented by an open circle at -1 not including which goes to negative infinity.
