Your friend is thinking of two numbers.

Mathematics
1 answer:
frosja888 [35]2 years ago

Answer:

2) 2x = y + 13

Step-by-step explanation:

We have to translate the given information into an equation. We don't know what the numbers are yet, so let the first number be represented by the variable x and the second number be represented by the variable y.

Start by breaking the sentence apart. "2 times the first number" gives us 2x. The "is" in the sentence means that 2x equals something, bringing us to 2x =. Finally, it says "13 more than the second number." 13 more would mean you have to add to the second number, represented by y, so this gives us y + 13\\. Put it all together and it is 2x = y + 13\\.

Which choice is the equation of a line that passes through the point (–6, –2) and is perpendicular to the line represented by th
kobusy [5.1K]

Answer:

  B.  y = 1/3x

Step-by-step explanation:

The slope of the given line is -3, so the slope of the perpendicular line will be the negative reciprocal of that: -1/(-3) = 1/3. This eliminates choices A and C.

We can find the y-intercept (b) if we use the given point values in the equation ...

  y = 1/3x +b

we get ...

  -2 = (1/3)(-6) +b

  -2 = -2 +b . . . simplify

  0 = b . . . . . . . add 2

So, the equation of the perpendicular line through the given point is ...

  y = 1/3x . . . . matches choice B

_____

<em>Alternate solution method</em>

You can try the given point in the given equations. You will find that only the equation of choice B will work.

If the Zeros are 2 and 8 what's the axis of symmetry?
lions [1.4K]

Answer:

Step-by-step explanation:

x=2,x-2=0

x=8

x-8=0

y=(x-2)(x-8)=x²-2x-8x+16=x²-10x+16

=x²-10x+25-25+16

=x²-10x+25-9

y=(x-5)²+9

axis of symmetry is x-5=0 or x=5

So right now i'm doing "solving Inequalities" i need help with this question<br> 3v-12&gt;5v+10
LenKa [72]

Answer:

v < -11

Step-by-step explanation:

  1. Combine like terms: 3v - 5v > 12 + 10
  2. Simplify: -2v > 22
  3. Divide each side by -2 to cancel out the -2 next to v. It should now look like this: v < -11

I hope this helps!
