Please correct my mistakes and share with me how you've received your answer.
If you are in connexus here are all of the answers.
1 yes
2 no
3 (4,0) & (3,-1)
4 96
5 3y+6=5y-8
6. An equation can be used to predict values from a pattern by merely substituting any value to determine the equivalent value. An example is the geometric series which has a standard equation of an = a1 * r^(n-1) and is used to predict the nth term of the series
7 Price # of pizzas
1.)50 1
3.)00 2
4.)50 3
6.)00 4
each pizza costs 1.50 so you add on 1.50 to each slice of pizza you buy
just took the test got 100%
Better go back to #3 and look again.
The others look ok.
For #3 is 1 wrong or both?
(0,3)
y-x+3
1. Is (0,3) a solution to the equation y=x+3?
To determine if (0,3) is a solution to the equation y=x+3, we need to substitute the values of x and y into the equation and check if it is true.
Plugging in x=0 and y=3 into the equation y=x+3, we get:
3 = 0 + 3
3 = 3
Since the equation is true, the answer is "yes," (0,3) is a solution to the equation y=x+3.
2. Is (1,-4) a solution to the equation y=-2x?
Similar to the previous question, we substitute the values of x and y into the equation and check if it is true.
Plugging in x=1 and y=-4 into the equation y=-2x, we get:
-4 = -2(1)
-4 = -2
Since the equation is false, the answer is "no," (1,-4) is not a solution to the equation y=-2x.
3. Look at the following points: (4,0), (3,-1), (6,3), (2,-4). Which are solutions to y=x-4? Choose all correct answers.
To determine which points are solutions to y=x-4, we plug in the x and y values of each point into the equation and check if it is true.
a. (4,0):
0 = 4 - 4
0 = 0
b. (3,-1):
-1 = 3 - 4
-1 = -1
c. (6,3):
3 = 6 - 4
3 = 2
d. (2,-4):
-4 = 2 - 4
-4 = -2
The correct answers are (3,-1) and (2,-4), as they satisfy the equation y=x-4.
4. There are 8 crackers in 1 serving, 24 crackers in 3 servings, and so on. How many crackers are in a box of 12 servings?
To find the number of crackers in a box of 12 servings, we need to determine the pattern and apply it to the given information.
Given that there are 8 crackers in 1 serving and 24 crackers in 3 servings, we can deduce that there are 8 crackers per serving.
Therefore, in a box of 12 servings, we multiply the number of servings (12) by the number of crackers per serving (8):
12 * 8 = 96
So, there are 96 crackers in a box of 12 servings. The answer is Option B.
