I think the answer should be 2,3,4,
Answer:
For the first one the answers in order is
3x+4y
2x+5y+3
6x
2y-3x
6x-8
-3x-3
13x-9
0(arrow going out)
2x-3y+1
-4
16x-9y
15x-2
Step-by-step explanation:
I put parenthesis in each equation to help you see where to solve the equation first.
(x+2x)+4y
3x+4y
5y+6+2x-3(the 6 and -3 are apart, but you need to do that first)
2x+5y+3
3x-4x+7x(i did not need to put parenthesis here because they are all like terms)
-1+7x
6x
(-2x-x)+(7y-5y)
2y-3x
(-4x+9x)-8+x
5x-8+x
6x-8
(-2x-x)+(7-10)
-3x-3
(-4-5)+(7x+6x)
13x-9
5x-4x-2x+x(i did not need to put parenthesis here because they are all like terms)
x-1x
0
2x+(4y-7y)+1
2x-3y+1
4-3-5(I can not put parenthesis here because if i do it will look like you are supposed to multiply when you are not)
1-5
-4
14x+2x(-5y-4y)
16x-9y
(10x+5x)(-4+2)
15x-2
Answer:
70.47feet
Step-by-step explanation:
CHECK THE ATTACHMENT FOR THE INTERPRETATION OF THE QUESTION USING A FIQURE
From the attachment we can see that a triangle was formed, where the
OPPOSITE SIDE= X
HYPOTENUSE=76feet
From trigonometry,
Sin(θ)=opposite/Hypotenuse
Sin(68)= X/76
Cross multiply, we have,
X= Sin(68) × 76
X= 0.9272 × 76
X= 70.47feet
Therefore, the antenna is 70.47feet tall.
