What is the slope intercept form in equation form of this graph?
Answer:
y = 7/2x+5
Step-by-step explanation:
To find the slope we need two points
(-2,-2) and (0,5)
We can find the slope from the formula
m = (y2-y1)/(x2-x1)
m = (5--2)/(0--2)
m = (5+2)/(0+2)
m = 7/2
The slope is 7/2
The y intercept, or where it crosses the y axis, is 5
Using the slope intercept formula for a line
y= mx+b
y = 7/2x+5

Katie's orange tree has 30 oranges. Katie's tree has three times as many fruits as Lisa's did before Lisa harvested half of her limes on the tree. How many limes does Lisa have on her tree now?
Lisa has 5 limes left on her tree after harvesting half. So, the correct answer is option 5) 5.
Let's break down the problem step by step:
1. Katie's orange tree has 30 oranges.
2. Katie's tree has three times as many fruits as Lisa's did before Lisa harvested half of her limes.
3. Let's denote the number of limes Lisa originally had as x .
4. After Lisa harvested half of her limes, she was left with [tex]\( \frac{x}{2} \)[/tex] limes.
5. Since Katie's tree has three times as many fruits as Lisa's tree originally had, the total number of fruits on Katie's tree is 3x .
6. The problem states that Katie's tree has 30 oranges, so 3x = 30 .
7. Solving for x , we find [tex]\( x = \frac{30}{3} = 10 \).[/tex]
So, Lisa originally had 10 limes on her tree. After harvesting half of them, Lisa is left with [tex]\( \frac{10}{2} = 5 \)[/tex] limes.
Therefore, the correct answer is option 5) 5.
The Correct question is:
Katie's orange tree has 30 oranges. Katie's tree has three times as many fruits as Lisa's did before Lisa harvested half of her limes on the tree. How many limes does Lisa have on her tree now?
1)10
2)45
3)90
4)15
5)5
Lisa initially had 10 limes on her tree. After harvesting half, she has 5 limes remaining. Therefore, Lisa now has five limes on her tree.
To find out how many limes Lisa has on her tree now, we need to break down the problem step-by-step:
Katie's tree has three times as many fruits as Lisa's: 30 = 3x
Solving for x: x = 10
So, Lisa originally had 10 limes on her tree.
Next, we calculate how many limes Lisa has after harvesting half:
Lisa harvested half of the 10 limes:Number of limes harvested = 10 / 2 = 5 The remaining limes on Lisa's tree: Remaining limes = 10 - 5 = 5Therefore, Lisa has five limes on her tree now.
given m=1/3, what is the parallel slope? what is the perpendivular slope?
Answer:1/3 and -3
Step-by-step explanation:pararel slope is the same as mane slope, and perpendicular is opicite reciprical.
Answer:
parallel: m = 1/3
perpendicular: m = -3
Step-by-step explanation:
Parallel line:
Slopes of parallel lines are equal.
If the given line has slope 1/3, then the parallel line also has slope 1/3.
Perpendicular line:
The slopes of perpendicular lines are negative reciprocals. That means that the product of the slopes is -1. That also means that to find the slope of a perpendicular line to a given line, first find the reciprocal of the slope of the given line (flip the fraction), then change the sign.
The slope of the perpendicular line and the slope of the line must multiply to -1.
Start with the given slope, 1/3. Now flip it to get 3/1 which is simply 3. Now change the sign to -3. The slope of the perpendicular is -3.
Check: multiply the slopes. They must have a product of -1.
1/3 * (-3) = 1/3 * (-3/1) = -3/3 = -1
The product is -1, so the slope of the perpendicular, -3, is correct.

How do you solve this ?
Answer:
3y
Step-by-step explanation:
Simplifying
13x + -39y = 0
Solving
13x + -39y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '39y' to each side of the equation.
13x + -39y + 39y = 0 + 39y
Combine like terms: -39y + 39y = 0
13x + 0 = 0 + 39y
13x = 0 + 39y
Remove the zero:
13x = 39y
Divide each side by '13'.
x = 3y
Simplifying
x = 3y
When you find 100% of a number, how does your answer relate to the original number?
a. the numbers are equal.
b. it is less than the original number.
c. it is greater than the original number.
Answer:
i think c.
Step-by-step explanation:
The numbers are equal (choice A)
This is because 100% of something is that entire thing, not changed at all. It is not added to, or subtracted from. Example: 100% of 78 is 78. If you had 78 people in a room, and selected 100% of them, then you selected all 78 people.

A bag contains 6 blue marbles 10 red marbles and 9 green marbles. If 2 marbles are drawn at random without replacement what is the probability that to green marbles are drawn
Answer:
P(1 and 2 are green) = 3/25
Step-by-step explanation:
We need to know the total number of marbles
6 Blue + 10 red + 9 green = 25 marbles
P ( 1st marble is green) = green/ total
= 9/25
Since we don't put it back, there are
6 Blue + 10 red + 8 green = 24 marbles
P ( 2st marble is green) = green/ total
= 8/24 = 1/3
P(1 and 2 are green) = P(1st green) * P(2nd green)
= 9/25 * 1/3
= 3/25
To calculate the probability of drawing two green marbles consecutively without replacement, multiply the probability of drawing a green marble on the first draw (9/25) by the probability of drawing another green marble on the second draw (8/24, or 1/3), which equals 0.12.
Explanation:The question is asking about the probability of drawing two green marbles consecutively from a total of 25 marbles without replacement. The total number of marbles is comprised of 6 blue, 10 red, and 9 green marbles. The probability rule for independent events must be used in this scenario, which states that the probability of both events occurring is the product of the probabilities of each event.
Initially, you have 9 green out of 25 total marbles so the probability of drawing a green is 9/25. After having drawn one green marble, there are now 8 green out of a total of 24 marbles left in the bag, hence the probability of drawing one more green would be 8/24 or 1/3. Therefore, the probability of drawing two green marbles consecutively, without replacement is (9/25) * (1/3) or 3/25 or 0.12.

One evening 1400 concert tickets were sold for the Fairmont Summer Jazz Festival. Tickets cost $20 for covered pavilion seats and $15 for lawn seats. Total receipts were $24,000. How many tickets of each type were sold?
To determine the number of each type of ticket sold, a system of linear equations is set up and solved using the substitution method. The answer is 600 covered pavilion seats and 800 lawn seats were sold.
To solve this problem, we can set up a system of linear equations based on the given information. Let x be the number of covered pavilion seats sold and y the number of lawn seats sold. We have two equations:
x + y = 1400 (since 1400 tickets were sold in total)20x + 15y = 24000 (since the total receipts from ticket sales were $24,000)Now we can solve this system of equations using either substitution or elimination method. For simplicity, let's use the substitution method:
From equation 1, we can express x as:
x = 1400 - y
Now substitute x in equation 2:
20(1400 - y) + 15y = 24000
Simplify and solve for y:
28000 - 20y + 15y = 24000
-5y = -4000
y = 800
Since we know y, we can find x by substituting the value of y in x = 1400 - y:
x = 1400 - 800
x = 600
So, the number of covered pavilion seats sold was 600 and the number of lawn seats sold was 800.

a submarine travels 90 kilometers in 4 hours find the submarines rate of speed in kilometers per hour
Answer:
22.5
Step-by-step explanation:
To find the rate of speed per hour, you need to divide the kilometer (90) by the hours (4).
90/4=
22.5
The submarine's rate of speed is found by dividing the distance traveled (90 kilometers) by the travel time (4 hours), resulting in a rate of 22.5 kilometers per hour.
You need to use the formula for speed which is speed = distance ÷ time. In this case, the submarine travels 90 kilometers in 4 hours.
To calculate the rate of speed, divide the distance by the time:
Speed = 90 kilometers ÷ 4 hours = 22.5 kilometers per hour.
This means the submarine's rate of speed is 22.5 kilometers per hour.

lightning strikes the earth 1000 times every ten seconds. how many seconds does it take forr it to strike 7250 times?
Answer:
72.5 seconds
Step-by-step explanation:
7250 ÷ 1000 = 7.25
7.25 x 10 = 72.5 seconds
Answer:
72.50 s
Step-by-step explanation:
Lightning strikes the earth 1000 times every 10 seconds. First calculate time taken for each lightning to strike the Earth by unitary method:
1000 times lightning takes 10 s
1 time lightning would take [tex]\frac{10s}{1000} = 0.01 s[/tex]
Multiply 7250 with this time. It will yield amount of time in which lightning would strike 7250 times:
[tex]\frac{10s}{1000}\times 7250 =72.50 s [/tex]
