Answer:
A
Step-by-step explanation:
Since we're dealing with perpendicular lines, we take the recipricol of the m value of the original equation.
So the slope we're dealing with is 1/2.
And the equation we have so far is
y = 1/2x + b
Now we solve for b by plugging in the point (4,2).
2 = 1/2(4) + b
2 = 2 + b
b = 0
So the final equation is
y = 1/2x
The commutative property means that the numbers can be switched when multiplying. The second one shows the associative property, where the numbers can be grouped differently. The third one shows the identity property, where multiplying by 1 will get the same number you are multiplying it by. The fourth one shows the zero property, where multiplying by zero will get zero.
Therefore, the answer is the first one because the numbers are simply flipped.
Can you explain your question I’m not sure what equation
There are several ways to answer this question and I will use this approach. Since Johnny reads at a ratio of 7:3 it can be stated that for every 10 pages in a book containing 500 pages Johnny will read 7 of those pages. There are 50 groups of 10 in a 500-page book (50 x 10). Take the ration 7:3 times 50 and use the distributive property: 7:3(50) = (7 x 50):(3 x 50) = 350:150. Based on this Johnny has read 350 pages and has 150 pages remaining.
Simple, just take 125 divided by 2.
Since 2 can't go into 1, you go over 1 more number, which gives you 12. Thus, 2 can go into 12, 6 times. Which leaves you the 5, 2 can go into 5, only 2 times, thus you have a remainder of 1. Put in your decimal point, and 2 can go into 10, 5 times. Thus, your answer is 62.5, 62 1/2, or 125/2.
