Answer:
x = 3
Step-by-step explanation:
Given
f(x) = - 10x + 45 and f(x) = 15, then equating gives
- 10x + 45 = 15 ( subtract 45 from both sides )
- 10x = - 30 ( divide both sides by - 10 )
x = 3
Answer:
1. D 2. A 3. Distribute the four in 4(x+1)
Step-by-step explanation:
1. It says that Jamie is saying that they are "not equivalent".
2. You have to use the distributive property to distribute the 4 to x and to the 1.
3. After distributing, compare the two expressions and now see if they are equivalent or not.
The answer is 700 meters
why?
1. km=1000.m so when you move the 1 to the right .1 you have to do the same woth 1000. which will be 100.0
the answer is 20
why?
1 quart=4 cup so change 1 to 5 which means *5 and the same with cups 4 to 20 which means *20
Answer:
2-square root 3, 2+ square root 3
Step-by-step explanation:
If the polynomial has rational and real coefficients, the roots will be "conjugates" of each other. That is, the sum of the root should be a rational number. So, the irrational parts will be opposites, while the rational parts remain the same.
2±√3 . . . can be the roots of p(x) when p(x) has rational real coefficients
Answer:
30....:)
Step-by-step explanation:
So looking at the graph. L to the midpoint of K is 15.
lets ignore N.
The graph has a line between k to the midpoint of L. So does L to the midpoint of k, which was 15.
This line means they are parrelel, so we can conlude that they both equal 15.
Adding the two together, we find KL is 30 in length.
The graph says KL is parrelel to JM.
So we can conclude that JM is 30.
<u>That looks like D on your answer sheet</u>
The only thing I am not sure of is what the N has to do with the answer.
They give you the value of N, and say the use N, however you do not need N to find the answer.
I think that the answer is 30, and it is included on the answer sheet as well. But fair warning that N did not have a use in it.
Hope this helps :)
