Let x be the number of months the calf grows.
1000 = 65x + 90
65x=910
x= 14
Answer:
Step-by-step explanation:
1) y = 2x ----------(I)
x + y = 6 -----------(II)
Plug in y =2x in equation (II)
x + 2x = 6 {Add like terms}
3x = 6
x = 6/3
x = 2
Plugin x = 2 in (I)
y = 2*2
y = 4
<u>Check: </u>
LHS = x +y
= 2 + 4
= 6 = RHS
2)5x + 10y = 3 ------------(I)
x = (-1/2) y ------------(II)
Substitute x = (-1/2)y in (I)
Substitute y = (2/5) in equation (II)
<u>Check:</u>
Substitute x and y value in equation (I)
3) y - x = 3x + 2
y = 3x + 2 + x
y = 4x + 2 ---------------(I)
2x + 2y = 14 - y
2x + 2y +y = 14
2x + 3y = 14 ------------------(II)
Substitute y = 4x + 2 in equation (II)
2x + 3(4x +2) = 14
2x + 3*4x + 3*2 = 14
2x + 12x + 6 = 14
14x + 6 = 14
14x = 14 - 6
14x = 8
x = 8/14
x = 4/7
Substitute 'x' value in (I)

<span>Let the distance of the point be P. From the question, the distance, P, is square root of the sum of the coordinates (x, y); so we have (X^2, Y^2) From the origin we have (0, 0) From elementary mathematics, distance of a point is . âš(X2 -X1)^2 - (Y2 - Y1)^2
So basically this is just the difference of the squares at varying points of X and Y.
At the origin, X1 = 0 and Y1 = 0 and so our equation reduces to âš(X2-0)^2 + (Y2 -0)^2. This becomes P =âšX^2 + Y^2</span>
Answer: f(x)= 3/2x-2
Step-by-step explanation:
So if you know how to graph on a calculator and put all the points in, it'll give you all the points plotted and when i did that i got
f(x)= 3/2x-2
