Answer:
We can determine which image is correct by the second equation, only in one of the images the line is correct.
X-y=1
So x = 1+ y
If y is one x should be two.
Only in one image that is true, the third image.
Answer:
a) Requires you to plot the point on the graph so you'll just have to plot (4,2600) using the graph
c) Here they have given the years as 3.5, using this inorder to determine our value we need to draw a straight line upwards from (3.5,0) and keep extending until it touches the graph.Then draw another line from the point where it touches horizontally toward the left until it cuts the yaxis and that will be your value answer
I hope it's clear I'm really sorry it's so hard to explain in words.
Btw if you could mark it as brainliest that would be great ^^
Answer:
Katie is 6 years old and Thomas is 3 years old
Step-by-step explanation:
Given that we should let K and T be the current ages of two siblings, Katie and Thomas.
If Katie is currently twice the age of Thomas then,
K = 2T
and in 6 years, Katie will be 4 times Thomas's current age then
K + 6 = 4T
Solving both equations simultaneously by substituting the value of K given in the first equation into the second
2T + 6 = 4T
Collect like terms
6 = 4T - 2T
6 = 2T
Divide both sides by 2
T = 3
Recall that K = 2T
K = 2 * 3
= 6
Hence Katie is 6 years old while Thomas is 3 years old
Answer:
The proof is given below.
Step-by-step explanation:
Given: ( the correct question and ans is as follow )
sin (x + y) = 3sin ( x - y)
To Prove
tan x = 2 tan y
Proof:
Using the identities
we get
Now we will take sin x . cos y to the left hand side and cos x . sin y to the right hand side,we get
