Point Slope Form- y-1=4(x+2)
Slope Intercept Form- y=4x+9
Answer:
The augmented matrix of the system is .
We apply operations rows:
1. We swap row 1 and 2 and obtain the matrix .
2. Of the above matrix we subtract row 1 from row 2 twice (R2 - 2R1) and we subtract row 1 from row 3, 5 times. (R3-5R1). We obtain the matrix
3. Of the above matrix we subtract row 2 from row1 twice (R3 - R2) and multiply the row 1 by -1 (-R2). Weobtain the matrix .
Since each pivote is an one then we conclude that the above matrix is the reduced row-echelon form of the matrix of the system.
Apple: £20
Banana: £60
I believe this is the answer because between the two problems there is a difference of £60. So I saw three apples were gone from the next so 60 divided by 3 is 20. Then we need to find the banana price. 20 x 7 = 140. 200 - 140 is 60. So the banana is 60 and the apples are 20.
Answer:
KJ = 22
Step-by-step explanation:
From the given diagram, since the figure are similar we can compare their sides.
So that,
=
Let KJ be represented by x. But;
JL = 28, PR = 42 and PQ = 33
Thus,
=
x =
=
= 22
x = 22
The n,
KJ = 22
Answer:
The number is 13.
Step-by-step explanation:
We are given the following in the question:
Let x be the variable, then according to the question
"The sum of eight and eleven times a number is 151"
We can write the equation:
Solving the equation, we can write:
Thus, the number is 13.
