X+y+5=0
y=-x-5
If a solution exists y=y so we can say
x^2-9x+10=-x-5 add x+5 to both sides
x^2-8x+15=0 now factor
x^2-3x-5x+15=0
x(x-3)-5(x-3)
(x-5)(x-3) so x=3 and 5, using y=-x-5
y(3)=-8 and y(5)=-10
So the two solutions are:
(3,-8) and (5,-10)
C4,1 because I solved it and it showed me
I'm not quite sure if this is what you need, but I am going to solve these equations by elimination. x= 8/17 and y = 11/17 (8/17, 11/17).
The future worth (F) of the current investment (P) with interest i is calculated through the equation,
F = P x (1 + i)^n
Substituting the known values to the given equation,
F + (2500) x (1 + 0.03)^5 = 2898.19
Thus, the account would have approximately 2898.19.
Answer:
<em>Functions evaluated at x = -1</em>
A. a(-1) = -2(-1) + 3 = 5
B. b(-1) = 0 (as per graph)
C. <u>Find the equation first:</u>
- m = 4/8 = 1/2
- c(x) = 1/2x - 4
- c(-1) = -1/2 - 4 = -4.5
D. d(-1) = (-1)² - 4 = -3
E. e(-1) = 2 (as per table)
F. f(-1) = 5/2 = 2.5 (as per graph)
G. g(-1) = 2(3)⁻¹ - 2 = 2/3 - 2 = - 1 1/3
H. h(-1) = 2 (as per table)
<u>The order:</u>
- C >> D >> G >> B >> E and H >> F >> A
