Answer:
(-1,1)
Step-by-step explanation:
x + 9y = 8
-6x - 9y = -3
Add the two equations together to eliminate y
x + 9y = 8
-6x - 9y = -3
---------------------
-5x = 5
Divide by -5
-5x/-5 = 5/-5
x = -1
Now solve for y by substituting into the first equation
x+9y = 8
-1 + 9y =8
Add 1 to each side
-1+1 + 9y = 8+1
9y=9
Divide each side by 9
9y/9 = 9/9
y = 1
Answer:
You "FOIL" (First, Outer, Inner, Last).
Step-by-step explanation:
You "FOIL" (First, Outer, Inner, Last). Basically, you have to multiple each term by each of the other terms.
(3x+2)(4x-7)
(3x)(4x) + (17)(3x) + (2)(4x) + (2)(-7)
12x^2 - 21x + 8x - 14
12x^2 - 13x - 14
Answer:
x+
Step-by-step explanation:
Um the angle is 72. No ladder can make an angle of 72. Anyway trigonometry is the only way to solve this.
The function is sin. Sin(72)= opposite/5(hypotenuse)
5sin(72)=4.76 metres to 2 decimal places
