The solution to the following equation is x=0
6x+7= 1/2x+7

True
or
False
(The 1/2 is a fraction)

Answers

Answer 1
Answer: True

Explanation:
If X=0 then that would make the problem 6(0)+7=1/2(0)+7. Anything multiplied by 0 is 0 so that would cancel the 6 and the 1/2. That means that you would be left with 7=7
Answer 2

Answer:

True

Step-by-step explanation:

To see if that is the solution, lets solve the equation.

6x + 7 = 1/2x + 7

Subtract 1/2x from each side to bring it to the right

6x - 1/2x + 7 = 7

Subtract 7 from each side to bring it to the left

6x - 1/2x = 7 - 7

Simplify it

5.5x = 0

Divide 5.5 from each side to leave x alone.

x = 0

The answer is true. I hope this helps!

Answers

Answer:

For the first one

x= About 32.02

y= About 27.58

z= About 55.16

For the second one

x= 6

y= 12

z= about 16.97

Step-by-step explanation:

Their all really simple

These are special right triangles, a 45, 45, 90 and a 30, 60, 90 triangle. The formla for these triangles are shown in the picture below.

Now for the first one ]

Lets find Z first

Now this is a 45 special right triangle so we know the other side s 39 but the hypotenuse is n[tex]\sqrt{2}[/tex] (I’m using N becuase x and y is taken) So n is basically 39 (look at the image below) and just solve that. Now for x and y. We know its a 30, special right triangle. We know that 39 here is already the answer for  N[tex]\sqrt{3}[/tex] so make an equation to find the n and you’ll get 27.58 for y. Now For x, its just doubled the y.

For the second one this is easier

We know that the x is (6) becuase its already in the radical number, now to find the hypotnuse, we double that and get 12. Now we know what y is becuase since the 2nd triangle is a 45/45/90, we know that 12 is y, the hypotnuse is just N[tex]\sqrt{2}[/tex] and we just plug in the n with 12 and solve it!

I really need help on this question! Thank you!

Answers

Answer:

A

Step-by-step explanation:

We know the following:

[tex]OE=5\\\\FG=4\\\\EF=8\\\\[/tex]

so the segment EF is equal to

[tex]EF=EG+GO+OF\\\\[/tex]

and here we can do a trick :)

[tex]EF=(EG+GO)+GO+(OF+OG)-2GO\\\\[/tex]

you see it's the same

[tex]EF=EO-GO+FG\\\\[/tex]

now we plug the values given

[tex]8=5-GO+4\\\\8=9-GO\\\\GO=9-8\\\\GO=1[/tex]

so it's option A

C The number that is 2 to the left of -5 on the number line
D The number that is 2 to the right of -5 on the number line

Answers

Answer:

B

Step-by-step explanation:

when rewriting it, it would be 2+5 because subtracting a negative number is the  same as adding.

so it would be 5 to the right(since you are increasing/adding) to 2 (the beginning/starting point)
