Najat is selling raffle tickets. The table shows the cost (in dollars) of buying different numbers of tickets.
Using x for the number of tickets and y for the cost, do the following.
Write an equation relating x and y
Answers
Answer:
The equation relating x and y is: y=4x
Step-by-step explanation:
Let x represent number of tickets
and y represent cost
a) Plot the ordered pairs
The ordered pairs (1,4),(2,8),(3,12),(4,16) is plotted in figure attached.
b) Write an equation relating x and y
y= 4x
Now checking by putting values of x to see, if we get values of y
if x=1, then y=4x => y=4*1 =>y=4
if x=2 then y=4x => y=4*2 =>y=8
if x=3 then y=4x => y=4*3 =>y=12
So, we get same values as table.
The equation relating x and y is: y=4x

Vertical Line Test - A function's x-values must have only 1 y-value corresponding to it. If the function fails to pass this, it is not a function.Step-by-step explanation:
When we apply the Vertical Line Test to the 1st graph, it does not pass it. Therefore, the 1st graph is not a function.
When we apply the Vertical Line Test to the 2nd graph, it does not pass it. Therefore, the 2nd graph is not a function.
When we apply the Vertical Line Test to the 3rd graph, it does not pass it. Therefore, the 3rd graph is not a function.
When we apply the Vertical Line Test to the 4th graph, it does pass it. Therefore, the 4th graph is a function.

Help!? Helping my son with geometry ... I have no clue what I’m doing here
Answers
We are Given:
∠1 = 65°
Finding the measure of all other angles with proof:∠2:
∠1 + ∠2 = 180° (angle 1 and 2 form a Linear Pair)
65 + ∠2 = 180 (Angle 1 = 65°)
∠2 = 180 - 65
∠2 = 115°
∠3:
∠1 = ∠3 (Angle 1 and 3 are vertically opposite)
65 = ∠3 (Angle 1 = 65°)
∠3 = 65°
∠4:
∠4 = ∠2 (Vertically opposite angles)
∠4 = 115° (∠2 = 115°)
∠5:
∠5 = ∠1 (Corresponding angles)
∠5 = 65° (∠1 = 65°)
∠6:
∠6 = ∠2 (Corresponding angles)
∠6 = 115° (∠2 = 115°)
∠7:
∠7 = ∠3 (Corresponding Angles)
∠7 = 65° (∠3 = 65°)
∠8:
∠8 = ∠4 (Corresponding angles)
∠8 = 115° (∠4 = 115°)

Write sin(x+1) in terms of unshifted sine and cosine. Write your answer using decimals.
Please provide explanation, I’m confused.
Answers
Answer: sin(x + 1) = 0.841*cos(x) + 0.540*sin(x)
Step-by-step explanation:
Here we can use the relation:
Sin(a + b) = sin(a)*cos(b) + sin(b)*cos(a)
In this case we have:
sin(x + 1)
This means that the graph of sin(x) is shifted one unit to the left.
But we can write this, using the above relation, as:
sin(x + 1) = sin(x)*cos(1) + sin(1)*cos(x)
Now we have no longer a shift, and we can replace:
sin(1) = 0.841
cos(1) = 0.540
Then:
sin(x + 1) = 0.841*cos(x) + 0.540*sin(x)
Chaz kept a record of how many gallons of gas he purchased each day last week. Drag and drop the days into the correct boxes to order the days from the least amount of gas Chaz purchased to the greatest amount of gas Chaz purchased.
Day Gas (in gallons)
Monday 4.5
Tuesday 3.6
Wednesday 4.252
Thursday 3.71
Friday 4.255
Answers
Answer:
The arrangement of days from least to greatest according to number of gallons is:
Tuesday
Thursday
Wednesday
Friday
Monday
Step-by-step explanation:
The given amount of gallons is in decimal form and we have to arrange the numbers in the order from least to greatest.
4.5 is the largest number in the given numbers.
Then comes 4.252 and 4.255
As 0.252<0.255 so 4.252 will be smaller.
The smallest number is 3.6
Arranging the numbers, we get
3.6
3.71
4.252
4.255
4.5
Now arranging the corresponding day to each number,
The arrangement of days from least to greatest according to number of gallons is:
Tuesday
Thursday
Wednesday

The area of the postcard pictured below is 24 square inches. What is the width b of the message section (in inches)? Pick the equation that would best model this situation.
A. 4(b + 3) = 24
B. 3(4 + b) = 24
C. 4(b - 3) = 24
D. 3(b - 4) = 24
Answers
Answer:
Step-by-step explanation:
4(b + 3) = 24
Answer:
A. 24 = 4(b + 3)Step-by-step explanation:
Area is equal to length times width. In this case, the length is b + 3 (since both b and 3 are part of the width, with the length being 4.
Substitute into the equation for area:
a = lw
a = 4(b + 3)
The area is 24, so the final answer is:
A. 24 = 4(b + 3)write an equation of the line that passes through (-1, 3) and has a slope of -4
Answers
Answer:
y = -4x - 1
Step-by-step explanation:
We are given the slope so we can find the y intercept using slope intercept [ y = mx + b ]
y = -4x + b
3 = -4(-1) + b
3 = 4 + b
-1 = b
Now, put everything we know and solved for back into the formula.
y = -4x - 1
