Could you maybe add more info? like a story or something
Multiply 2nd equqation by -1 and add to first
5x+4y=22
<u>-3x-4y=-10 +</u>
2x+0y=12
2x=12
divide by 2
x=6
sub back
3x+4y=10
3(6)+4y=10
18+4y=10
minus 18 both sides
4y=-8
divide by 4
y=-2
(x,y)
(6,-2) is solution
Answer:
Step-by-step explanation:
The triangle is an isosceles triangle. Because the triangle is an isosceles triangle, the height and base of the triangle are equal to eachother.
a² + b² = c²
right now we have c² which is 7
a² + b² = 7
because a² and b² are = to eachother
now im lost dony listen to me lol.
Answer:
4/5 is the slope
Step-by-step explanation:
the formula is y=mx +b
m = slope
b= y intercept
Therefore, the slope in 4/5
Using the decay formula: Total = start value x (1 - rate)^time
Total = 23,840 x (1-0.04)^10
Total = 23,840 x (0.96)^10
Total = 15,849.61
Rounded to nearest whole number = 15,850
