1. (2x-3)(x-4)
2x(x) =2x^2
2x(-4)= -8x
-3(x)= -3x
-3(-4)= 12
2x^2 -8x-3x+12= 2x^2 -11x+12
2. (x+2)(x+5)
x^2+5x+2x+10= x^2 +7x+10
3. (3x-1)(x+2)
3x^2 +6x-x-2= 3x^2+5x-2
Answer: each hospice costs $4 and each shrub costs $9
Step-by-step explanation:
Let x represent the cost of one hospice.
Let y represent the cost of one shrub.
Mike spent $71 on four hospice and seven Travis. This means that
4x + 7y = 71- - - - - - - - - - - - -1
Danielle spent $53 on 13 hospice and three shrubs. This means that
13x + 3y = 53- - - - - - - - - - - 2
Multiplying equation 1 by 13 and equation 2 by 4, it becomes
52x + 91y = 923
52x + 12y = 212
Subtracting, it becomes
79y = 711
y = 711/79
y = 9
Substituting y = 9 into equation 1, it becomes
4x + 7 × 9 = 71
4x + 63 = 71
4x = 71 - 63
4x = 8
x = 8/4 = 2
Your answer would be 2s5<49
Answer:
£389.4 (interest earned, not total amount of money in account)
Step-by-step explanation:
Interest = principal * rate * time (years)
I = 885 * 0.0275 * 16
I = 398.4
Step-by-step explanation:
= 2x +b
Use the given point (2, 5)
5 = 2(2) +b
b = 5 -4 = 1
The equation of the line is
y = 2x +1
Note general form of the slope-intercept form of a line is y = mx +b, where m is the slope and b is the y-axis intercept
