Y = x-4
2x + y = 5
2x + (x-4) = 5
3x - 4 = 5
3x = 9
x = 3
Answer:
Obtuse because it bigger than an acute and a right angle
Answer:
I will be using differentiation method
Step-by-step explanation:
x^2+5x =-8
2×x ×x^2-1 +5x = -8
2x +5x = -8
7x = -8
divide both sides by the co-efficient of x
7x÷7=-8÷7
x =-1.5
Answer:
19.9
Step-by-step explanation:
we can write the following equation
18000(1.02)^n
where n is the number of years
so we have
26700=18000(1.02)^n
solve for n
1.483=1.02^n
use logs to solve for n
n=19.9
Simplify just means put together everything into one big thing. In this case that is just adding. To add a fraction and a decimal we have to convert the fraction into a decimal as well. The decimal form of 1/4 is 0.25, and as such, 3/4 is .75. This means we have -0.75+1.5. Adding a positive to a negative is the same thing as simply subtracting the first number from the second, or 1.5-0.75. This is .75. The answer is C.
