y = 4
Correct option is (C)
Step-by-step explanation:
-2x - 5y = -2 {taking minus(-) common}
⠀
2x + 5y = 2 [equation 1]
⠀
3x + 6y = -3 {taking 3 common}
⠀
x + 2y = -1 [equation 2]
⠀
{taking 2y of equation 2 on RHS}
⠀
x = -1 - 2y [equation 3]
⠀
{substituting of equation 3 in equation 1}
⠀
2(-1 - 2y) + 5y = 2
- 2 - 4y + 5y = 2
y - 2 = 2
y = 2 + 2
⠀
y = 4
Answer: x=3.40
Step-by-step explanation: apply exponent rule xln(3)= ln(42)
solve xln(3)=ln(42): x=ln(42)/ln(3) (fraction form)
(decimal) 3.40217... round it to the nearest hundreth= 3.40
I do not know if this is correct.
6 divided by 10
the fraction bar means divide
Answer:
(y-(-3))=4(x-(-1))
Step-by-step explanation:
formula for point slope form is:
y-y1=m(x-x1)
just plug in numbers from the point (-1, -3) for x1 and y1. The slope 4, would plug into m.
