Answer:
1. Slope = -2 , y-intercept = 1
2. Slope = 5 , y-intercept = -15
3. Slope = 1.5 , y-intercept = -2
4. Slope = -3 , y-intercept = 9
Step-by-step explanation:
1. The slope is -2 because using the formula y₁-y₂÷x₁-x₂ you can use the points given to you to get -2. It doesn't matter which one you pick as y1 or y2, just make sure you keep it consistent with the x numberings. I did 1--3 (which becomes 1+3) and 0-2. Those equal 4/-2 which gives you -2. Use these same steps for all of them, but with ones that don't have the points given, just pick two that are whole numbers and not decimals. For finding the y-intercept, just find the point that is on the y axis line. It is given on number one as (0,1). So, the y-intercept is 1. Hope this helps!
Hi! :)
This question states that four families each brought the same number of chairs. We know that 27 chairs are needed overall and 3 are still needed after the four families' contributions.
Knowing this, you can figure out that you could do 27-3. This equals 24, so you would then just divide 24 by 4, since there are 4 families.
Your final answer should be that each family brought 6 chairs.
Hope this helps!
Answer: 6
Step-by-step explanation:
From the question, we are informed that a factory uses 1/8 of a barrel of raisins in each batch of granola bars and that the factory used 3/4 of a barrel of raisins yesterday.
To calculate the number of batches of granola bars that the factory made yesterday, we divide 3/4 by 1/8. This will be:
= 3/4 ÷ 1/8
= 3/4 × 8/1
= 24/4
= 6
The company made 6 batches of granola bars
Answer:
1) 25/144 or 0.1736
2) 5/33 or 0.1515
Step-by-step explanation:
Total marbles: 5 + 7 = 12
1) 5/12 × 5/12
25/144
0.173611111
2) 5/12 × 4/11
5/33
