If (3 , 2) is a point on the line whose equation is y = 3x + k, determine the value of k.
Answer:
-7 =k
Step-by-step explanation:
y = 3x + k
Substitute 3 in for x and 2 in for y
2 = 3*3+k
2 = 9+k
Subtract 9 from each side
2-9 = k
-7 =k
Suppose m is the line with equation x=-5, line n is the equation y=1
Here is the complete question:
suppose m is the line with equation x=-5, line n is the line with equation y=1, line g is the line with equation y=x, and line h is the line with equation y=-2. Given A(9,-3), B(6,4), and C(-1,-5), what are the coordinates of the vertices of △A′B′C′ for each reflection?
1. Rx-axis
2. Ry-axis
Answer with step-by-step explanation:
1. When you get the reflecting coordinates along x-axis, the signs of the y coordinates changes. Therefore, A(9,-3), B(6,4), and C(-1,-5) becomes:
A(9, 3), B(6, -4), and C(-1, 5).
2. When you get the reflecting coordinates along y-axis, the signs of the x coordinates changes. Therefore, A(9,-3), B(6,4), and C(-1,-5) becomes:
A(-9, -3), B(-6, 4), and C(1, -5).

What is the rate of change of the following equation? y = -5/3x
Answer: -5/3
Step-by-step explanation:
In an equation y = mx + b, m is the value of the slope. The slope is the same as the rate of change. In this case, m = -5/3, thus the rate of change is -5/3.

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 95 miles per hour. The westbound train travels at 115 miles per hour. How long will it take for the two trains to be 336 miles apart? Do not do any rounding.
Answer:
It will take 1.6 hours for the two trains to be 336 miles apart.
Step by step explanation:
Given that:
Speed of eastbound train = 95 miles per hour
Speed of westbound train = 115 miles per hour
Combined speed = 95+115 = 210 miles
Distance = 336 miles
[tex]Speed = \frac{Distance}{Time}\\\\210 = \frac{336}{Time}\\\\Time = \frac{336}{210}\\\\Time = 1.6\ hours[/tex]
Hence,
It will take 1.6 hours for the two trains to be 336 miles apart.

The graph shows the distance Kerri drives on a trip. What is Kerri's speed?
Driving Time and Distance
A. 25 miles per hour
B. 60 miles per hour
C. 75 miles per hour
D. 50 miles per hour
Answer:
Kerri's speed = 50 mile per hour. Therefore option (D) is true.
Step-by-step explanation:
Given the distance-time graph
It is clear from the distance-time graph that:
at Time = 1 hour, Distance = 50 milesat Time = 2 hours, Distance = 100 milesso the two points on the distance-time graph is:
(1, 50)(2, 100)Finding the slope between the points to determine the speed.
Please note that the slope between the points represents the speed or rate of change.
Speed = Rate of change = y₂-y₁ / x₂-x₁
= 100 - 50 / 2-1
= 50 / 1
= 50 miles per hour
Thus, Kerri's speed = 50 mile per hour. Therefore option (D) is true.

This recipe makes 8 portions of porridge. Complete the amount of each ingredient that is needed to make just 5 portions. Recipe: Serves 8 400 g oats 1.2 l milk 40 g sugar
Answer:
5 portions of porridge requires
250g of oats, 0.75L of milk and 25g of sugar
Step-by-step explanation:
This recipe makes 8 portions of porridge. Complete the amount of each ingredient that is needed to make just 5 portions.
The ingredients for the recipe = Oats, Milk, Sugar
Hence:
For Oats
8 portions of porridge = 400g of oats
5 portions of porridge = x
Cross Multiply
8x = 5 × 400
x = 5 × 400/8
x = 250g of oats
For Milk
8 portions of porridge = 1.2 L of milk
5 portions of porridge = x
Cross Multiply
8x = 5 × 1.2
x = 5 × 1.2/8
x = 0.75 L of milk
For sugar
8 portions of porridge = 40g of sugar
5 portions of porridge = x
Cross Multiply
8x = 5 × 40
x = 5 × 40/8
x = 25g of sugar
Hence:
5 portions of porridge requires
250g of oats, 0.75L of milk and 25g of sugar

Answer: the babies
Step-by-step explanation:
The experimental unit in an experiment is the one on which the experiment is performed. According to the given experiment, the motive is to identify which brand of baby food is helpful in producing healthier babies which can be determined by the weight gain in babies during first few months after providing the baby food.
Here, the experiment units are the babies which are provided with foods of different baby food brands to check their weight gain and determine their health.
Raina drank 5 L 400 ML of water on the first three days of the week each. The next 2 days she drank 3 L each and the remaining days of the week she drank only 1.500 L each .
How much water did she drink in that one week?
First three days;
5L 400 ML;
Next two days 3 L each = a total of 6 L
Remaining 4 days; 1.5 L each which is a total of 4 * 1.5 = 6 L
Total amount drank will be;
6 + 6 + 5L 400 ML
= 17L 400 ML
Therefore, she drank 17L 400 ML that week.
Answer:
14.4 lStep-by-step explanation:
First 3 days = 5 l 400 ml = 5.4 lThe next 2 days = 3l *2 = 6 lRemaining days = 1.5 l *2 = 3 lTotal in one week is:

Step-by-step explanation:
they both go thur the point (0,-4) so they both have the same b in the slope intercept from of y =mx +b
but.. they have a different slope... m , the graph has a slope m of 4/3 while the table has a slope of 1 , both positive.. :)
The equation given by the graph is y = (4/3)x - 4 while the table is y = x - 4. Both equation have a y intercept of -4.
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
From the graph, using the point (3, 0) and (0, -4):
y - 0 = [(-4 - 0)/ (0 - 3)](x - 3)
y = (4/3)x - 4
From the table using (0, -4) and (2, -2):
y - (-4) = [(-2-(-4))/(2-0)](x - 0)
y = x - 4
The equation given by the graph is y = (4/3)x - 4 while the table is y = x - 4. Both equation have a y intercept of -4.

What equation in slope intercept form represents the line that passes through the two points?
(5,7), (6,-2)
Answer:
[tex]y = -9x +52[/tex]
Step-by-step explanation:
Given
[tex](x_1.y_1) = (5,7)\\[/tex]
[tex](x_2,y_2) = (6,-2)[/tex]
Required
Determine the equation in slope intercept form
First, we calculate the slope of the line:
[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]
This gives:
[tex]m = \frac{7 - (-2)}{5 - 6}[/tex]
[tex]m = \frac{7 +2}{-1}[/tex]
[tex]m = \frac{9}{-1}[/tex]
[tex]m = -9[/tex]
Th equation is then calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
This gives:
[tex]y - 7 = -9(x - 5)[/tex]
Open bracket
[tex]y - 7 = -9x +45[/tex]
Make y the subject
[tex]y = -9x +45+7[/tex]
[tex]y = -9x +52[/tex]
