Answer:

y = 0.5x -3

Step-by-step explanation:

Slope-intercept form is y=mx+b. The y-intercept (where it crosses the y axis, represented by b) is -3. The rise over run is 1/2, which is the slope.

Answer: y = x/2 - 3

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis

change in the value of y = y2 - y1

Change in value of x = x2 -x1

y2 = final value of y

y 1 = initial value of y

x2 = final value of x

x1 = initial value of x

From the graph,

y2 = - 1

y1 = - 2

x2 = 4

x1 = 2

Slope,m = (- 1 - - 2)/(4 - 2) = 1/2

To determine the intercept, we would substitute x = 4, y = - 1 and m= 1/2 into

y = mx + c. It becomes

- 1 = 1/2 × 4 + c

- 1 = 2 + c

c = - 1 - 2 = - 3

The equation becomes

y = x/2 - 3

Step-by-step explanation:

Given

Copies = 2102

Photos =5

Required

The number of times the photo will appear

The interpretation of the question is to determine the number of times the 5 photos will appear in each copy.

From the question, we understand that the photos will appear once in a copy.

By extension, the 5 photos will appear once in other copies.

Find the measure of angle C and angle D. show your work.​
Georgia [21]

Answer:C=40 degrees D=76 degrees

Step-by-step explanation:

Because of a theorem angle c and d equal angle DEF

so here is our equation:4y+(7y+6)=116

Open the parentheses

4y+7y+6=116

-6 on both sides

4y+7y=110

11y=110

Divide both sides by 11

y=10

Now we have to substitute

C=4y=4(10)=40

D=7y+6=7(10)+6=70+6=76

Which function is shown in the graph?
Mrac [35]

Answer:

Option 3. y = csc ∅ is the right answer.

Step-by-step explanation:

In a function y = cosec ∅  we put the value of ∅ at 0,π/4,π/2,π,3π/2.

y = cosec 0 = ∞ Therefore function is not defined at ∅ = 0

y = cosec π/4 = √2 = 1.41

y = cosec π/2 = 1

y = cosec π = ∞ not defined

y = cosec 3π/2 = -1

y = cosec 2π = ∞ again not defined

While analyzing the value of expression we can say that the graph is of y = cosec ∅.

Similarly if we analyze other expressions for the values of ∅ then the graph will not match.
