Answer:
y = -4
x = -2
Step-by-step explanation:
Hi there...
y = 2x
y = -x - 6
Since why is equal to 2x, we can plug it in for y in the second equation. Here's what I mean...
2x = -x - 6
add x on both sides...
3x = -6
divide by 3 on both sides...
x = -2
Now, plug in x for y. Here's what I mean...
y = 2x
y = 2 (-2)
y = -4
Hope this helps :)
Multiply 9 and 5 then multiply by .5 giving you 22.5 so I’d say that’s your best option
Answer:
X = 18
Y = 9√3
Step-by-step explanation:
use sin equation for right angle triangle
The sine of the angle
= ( the length of the opposite side ÷ the length of the hypotenuse.)
according to this question,
sin 30 = 9 / X
1/2 = 9 / X
X = 18
use cosine to find y
The cosine of the angle
= (the length of the adjacent side ÷ the length of the hypotenuse.)
cos 30 = y/x
√3/2 = y/ 18
y = 9 ✓3
Answer:
Okay, so this is confusing because of the negitave. Is that supposed to be there?
Step-by-step explanation:
The answer is A.
We know this because the exponents are in the form 2*t.
The final form will be (1/2)^2t
So I am not sure where the negitave came form because in every number sentence I solved they had no negitave exponent. Hope this is useful.
