Answer:
X = 1
Step-by-step explanation:
1) Move the 3x to the left hand side and change its sign:
4x-19+3x=-12
2) Move 19 to the right hand side and change its sign:
4x+3x=-12+19
3) collect the like terms:
4x+3x= 7x
-12+19= 7
4) Divide both sides by 7
X = 1
Answer:
the ladder reaches up to 9.75 ft. high
Step-by-step explanation:
a^2+b^2=c^2
plug in the numbers

a^2=95
then sq 95
a=9.75
Slope intercept form
y = mx + b
-2x + 5y = 10
5y = 2x + 10
Divide by 5
y = 2/5x + 2
