The answers are following
sol1 y = x-1
sol2 y= x+ 7
sol4 y = x+4
Step-by-step explanation:
Solution 1
Here we are going put the point in the given equation ( given in the options)
If the each point satisfies any equation, that will be the relationship between x and y.
Given points are (-3,-4) , (2,1) , (5,4)
Let us take the option C as y = x -1
-4 = -3-1
1 = 2-1
4=5-1
Putting each value in the given equation we get LHS and RHS are same for all points. so, C is the answer.
Similarly, option B is the answer of Solution 2
Each point satisfies the equation y = x +7
Solution 4
y = x +4
You are requested to check the options of Q3 once.
Two months ago a bicycle shop was able to sold 120 bicycle.
Then last month they were able to sold 138 bicycles already.
Let’s find for the percentage that increases during those months.
=> 138 – 120 = 18 – thus, during those months, they added 18 bicycle as sold.
=> 120 is our 100% and 18 is our increased percentage
=> 18 / 120 = 0.15 * 100 = 15%
Thus, it increases 15%, let’s check
=> 120 * .15 = 18.
For the tree, it would be 2ft, because 1:15 means for that every 15 feet the tree is in real life, the model would be 1 foot. with the door it would be 150inch, (10inch x 15= 150inch
I'm going to use just trig for this one.
so basically, you're going to find the adjacent side of a triangle by using the other side, so you would use tangent.
then just rearrange and solve for X
And the answer is
43.3 i think.
If i'm wrong please correct me
