-0 < x <0
-4
O 0
4
Answer:
The answer is the first one.
Step-by-step explanation:
Because this is a linear equation, it will continue on in both directions forever, so the both the x and y values to infinty can be included in this line.
Solve using cosine law only
Please please help this is due tomorrow morning
Hints:
Step 1: Use Sine law the the angle B.
a/Sin A=b/SinB=c/SinC
24/Sin61^=12/SinB (accross multiply)
SinB=12Sin61^/24
SinB=0.437309853 then convert to degree =25.9 degree( depends on question rounded how many decimal) Read the question it must notes there.
--> Angle C=180-61-25.9=93.1 degree.
Step 2: Use Cosine law to calculate.
c^2=a^2+b^2−2ab⋅cosC
c^2=24^2+12^2-2(24)(12)cos93.1
c^2=720-576(-0.054078812)
c^2=720+31.11494
c^2=751.1494
c=27.4

Jenny recorded the number of basketball shots she made for each game. The histogram below shows her data. How many times did Jenny make less than four shots in a game?
a. 4
b. 7
c. 5
d. 1
Answer:
Answer choice a is correct, the answer would be 4.
Step-by-step explanation:
The histogram shows that the bin from 1-3 has a height of 4 shots, and all of the bins to the right include values of ≥4.
The question asks for the number of games that had less than 4 shots, which means that and number of shots greater than or equal to 4 would not be counted. Thus, only the first bin is included in the answer.

using mental math find 4.623 x 1000. Please explain how you got your answer
Answer:
4 623
Step-by-step explanation:
4.623 x 1000
When multiplying by a positive power of 10, move the decimal by the number of zeros
Since we have 3 zeros, move the decimal 3 places to the right
4 623
Answer:
You can easily figure that
[tex]4.623 = 4623 \cdot 10^{-3}[/tex]
[tex]1000 = 1\cdot 10^3[/tex]
The multiplication: [tex](4623 \cdot 10^{-3}) \cdot (10^3)=4623[/tex]

please answer this (photo below)
Answer:
Please see attached image for the graph
Step-by-step explanation:
To graph the elevation versus time, we start by plotting the first point at time zero (when the climb begins) when Zane is 20 meters below the edge (-20 meters). This corresponds to the point (0, -20).
One second later (1 in the horizontal axis), Zane has moved up 4 meters, now reaching -16 meters. This is the point (1, -16) on the graph.
One second later at time 2 seconds, he is another 4 meters up which corresponds to the point (2, -12) on the graph.
you can go on like this plotting more points on the graph.
Please see the attached image that illustrates this and shows the appropriate line that represents Zane's position versus time (pictured in red)

Answer:
.42n = p
Step-by-step explanation:
We can write ratios to solve
2.52 / 6 = p/n
.42 = p/n
Multiply each side by n
.42n = p
Answer:
A is the answer
Step-by-step explanation:
You have to divide $2.42 by 6.
[tex]2.52/6=0.42[/tex]
The unit rate would be
[tex]p=0.42n[/tex]
So for every orange it will cost $0.42

-0.03x^2+1.53x=0
how would i go about solving for x?
Answer:
x = 0, 51
Step-by-step explanation:
→First, you need to factor out the GCF (Greatest Common Factor), which is -0.03x, like so:
-0.03x (x - 51) = 0
→Remove the -0.03 by divide it by both sides:
x(x - 51) = 0
→Separate each, like so:
x = 0
x - 51 = 0
→Solve for x:
x - 51 = 0
x = 51
Your solutions are, 0 and 51.

plz help with slope question
Answer:
-The equation:
[tex]y = x + 2[/tex]
Step-by-step explanation:
Use the Point-slope formula to get the slope-intercept equation:
[tex]y-y_{1} = m(x-x_{1})[/tex]
Use the given slope [tex]1[/tex] and point [tex](3,5)[/tex] for the point-slope formula:
[tex]y-5 = 1(x-3)[/tex]
-Then, solve:
[tex]y-5 = 1(x-3)[/tex]
[tex]y-5 = x - 3[/tex]
[tex]y-5 + 5 = x - 3 + 5[/tex]
[tex]y = x + 2[/tex]
-So, the answer is:
[tex]y = x + 2[/tex]
Answer:
C. [tex]y = x +2[/tex]
Step-by-step explanation:
→You can figure this out by plugging in the numbers into the point-slope form, like so:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-5=1(x-3)[/tex]
[tex]y - 5=x-3[/tex]
[tex]y = x +2[/tex]
When six is subtracted from five times a number, the result is 9
Given that, when six is subtracted from five times a number, the result is 9. The number is 3.
What is the number?Given that, when six is subtracted from five times a number, the result is 9.
Let the number be y, such that;
(5 × y) - 6 = 9
Next, we solve for y
(5 × y) - 6 = 9
5y - 6 = 9
5y = 6 + 9
5y = 15
y = 15 / 5
y = 3
Given that, when six is subtracted from five times a number, the result is 9. The number is 3.

A) One half-kilogram of bulk sunflower seeds costing 70¢ per 100 grams
or
B) A 500-milligram bag of prepackaged seeds costing $3.95
Answer:
choice A is better value
Step-by-step explanation:
1/2 Kg = 500 grams
0.7* 5=3.5 dollars for sunflower seeds
prepackaged seeds : 500 mg= 0.5 grams
so 0.5 grams cost 3.95 dollars
A cell phone plan costs $200 to start. Then there is a $50 charge each month. Write an equation relating the cost, y, and then number of months, x.
Answer:
y = 200 + 50x
Step-by-step explanation:
y = cost
x = number of months
The cost is equal to the cost to open the plan plus the monthly fee times the number of months
y = 200 + 50x
Answer:
y = 200 + 50x
Step-by-step explanation:
the cost = the base cost plus the monthly charge ($50 per the number of months you pay it)

A recipe for a batch of blueberry muffins calls for 3/5 of a cup of blueberries if Rallye wants to make 1/2 of batch of muffins for herself and her tennis
Answer:
She will use 3/10 cups of blueberry to prepare muffins for herself and tennis team
Step-by-step explanation:
If recipe for a batch of blueberry muffins calls for 3/5 cups of blueberries
If Rallye wants to make 1/2 batch of muffins, then she will use 1/2 of 3/5 cups of blueberry
That is,
1/2 of 3/5 cups of blueberry
=1/2×3/5
=3/10
