what is the gradient between (0,3) and (1,8).
Step-by-step explanation:
Given
(x1 , y1) = ( 0 , 3)
(x2 , y2) = ( 1 , 8)
Now
Gradient =
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
[tex] = \frac{8 - 3}{1 - 0} \\ = \frac{5}{1} \\ = 5[/tex]

Answer: B it seems like
Answer:
A
Step-by-step explanation:
We can see that the y intercept is equal to 1
which means that we have the following equation
mx+1=y
We just need to solve for m at this point
We can use the ordered pair (-2,2) to help
We know that
-2m+1=2
Solve for m
-2m=1
m= -1/2
Put this together and we get
-1/2m+1=y which is A
2. Ajar contains 10 marbles, 6 marbles are red, and 4
marbles are blue. If 2 marbles are chosen one at a time
without replacement, what is the probability that the first
marble will be blue and the second marble will be red?
A: 3/16 B: 6/25 C: 1/8 D : 12/45
Independent or Dependent:
Final Answer:
Answer:
A
Step-by-step explanation:
Note that there are 16 total marbles. A is simply a set of sequential events. On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375. Event B is translated into 2 events: Blue + (White or Red) or (White or Red) + Blue. The probabilities of each of these events, added together would be (2/16) * (14/15) + (14/16) * (2/15) = 0.2333333333; therefore, A is more probable.
Which point is the image of (-7,1) reflected across the y-axis? "-enter answer as an ordered pair without
spaces**
Answer:
The image point of (-7, 1) after reflection across the y-axis is:
(7, 1)Step-by-step explanation:
When a point P(x, y) is reflected across the y-axis, we reverse the sign of the x-coordinate while the y-coordinate remains the same.
Thus,
The rule to reflect a point across the y-axis is:
P(x, y) → P'(-x, y)
In our case, we are given the point (-7, 1)
Let say the point is A(-7, 1).
Thus, using the rule to reflect a point across the y-axis is:
P(x, y) → P'(-x, y)
A(-7, 1) → A'(-(-7), 1) → A'(7, 1)
Therefore, the image point of (-7, 1) after reflection across the y-axis is:

A train is traveling at a constant speed and goes 17 kilometers in 8 minutes. How far will the train travel in 60 minutes.
Answer:
Distance B = 1275 kilometers.
Step-by-step explanation:
Let the two distances and time be A and B respectively.
Given the following data;
Distance A = 17 kilometers.
Time A = 8 minutes.
Distance B =?
Time B = 60 minutes.
First of all, we would find the constant speed;
Speed = distance/time
Substituting into the equation, we have;
Speed = 17/8
Speed = 2.125 km/m
Now, to find the distance B;
Distance B = speed * time
Distance B = 2.125 * 60
Distance B = 1275 km
The ratio of destroyers to battleships in the navy is 20:15. If the total number of boats is 105, how many battleships are there?
Answer:
45
Step-by-step explanation:
20:15 the ratio can be turned to a fraction
20/15
simplify
4/3
so now add the numerator and the denominator and get 7
then do 105/7=15
and then you do
4x15=60 (Destroyers)
3x15=45 (Battleships)
45 is your answer

Solve 3x - 5 = 16
Write your solution starting with x= .
Answer:
x =7
Step-by-step explanation:
To solve this, you must get x by itself.
3x-5 = 16 1. Add 5 on both sides
3x = 21 2. Divide by 3 on both sides
x = 7
three times a number subtracted by 3 is 20
Answer:
3x - 3 = 20
Step-by-step explanation:
Times is a word that represents multiplication. A number can be represented by x.
3x - 3 = 20
Solving this:
3x - 3 = 20 1. Add 3 on both sides
3x = 23 2. Divide by 3 on both sides
x = 7 2/3

calculate the value of 1/3 a = -5
Answer:
- 15
Step-by-step explanation:
[tex] \frac{1}{3} a = - 5 \\ \\ a = - 5 \times 3 \\ \\ a = - 15[/tex]
Answer:
-15
Step-by-step explanation:
As you can see, the denominator of 1/3 is 3. 1 third of a is -5. So what you do is, you multiply -5 * 3 and that'll give you -15. So, it is equal to -15.

Step-by-step explanation:
A line through which two points would be parallel to a line with a slope of 3/4?
a
(0,-2) and (-4,-2)
b
(0,5) and (-4,2)
c
(0,2) and (-4,1)
d
(0,0) and (0,-2)
Answer:
F. (0, 5) and (-4, 2)
Step-by-step explanation:
We need to calculate the slope of each of the given sets of points until we find the set associated with a slope of 3/4:
F. (0,5) and (-4,2) As we go from (-4, 2) to (0,5), x increases by 4 and y increases by 3, so the slope is m = rise / run = 3/4. This is the line with slope 3/4.

write the following equation in slope- intercept form 6x+2y=20
Answer:
y = -3x + 10
Step-by-step explanation:
6x+2y=20
First, you want to subtract 6x from both sides.
2y=-6x+20
Now, you want to divide by 2 on both sides because you want to get y by itself.
y = -3x + 10
Answer:
Y = -3x + 10
Step-by-step explanation:
Subtract the 6x from both sides to get y by itself
You would have 2y=-6x+20
Divide everything by 2 for the correct formula format
You would have y=-3x+10

Roman was studying the life of fish, frogs, and turtles in
Doyle Park. In two hours, he counted 4 more frogs than
turtles. The number of fish he counted was twice the
number of turtles. In total, he counted 68 animals. How
many fish were there?
how many frogs were there? how many turtles were there?
Answer:
16 turtles
20 frogs
32 fish
Step-by-step explanation:
let 't' = # turtles
let '4 + t' = # frogs
let '2t' = # fish
t + 4 + t + 2t = 68
4t + 4 = 68
4t = 64
t = 16 turtles
4 + 16 = 20 frogs
2(16) = 32 fish
