Help needed pleaseee

Mathematics
1 answer:
ohaa [14]3 years ago
8 0

Answer:

A

Step-by-step explanation:

Since we're dealing with perpendicular lines, we take the recipricol of the m value of the original equation.

So the slope we're dealing with is 1/2.

And the equation we have so far is

y = 1/2x + b

Now we solve for b by plugging in the point (4,2).

2 = 1/2(4) + b

2 = 2 + b

b = 0

So the final equation is

y = 1/2x

Does this graph show a function?
Montano1993 [528]

Answer:

  A

2(x-1) ≥ 10 or 3-4x &gt; 15<br> Solve the compound inequality, and show work!
Veseljchak [2.6K]

Answer:

x\geq 6\text{ or } x

Step-by-step explanation:

We have the compound inequality:

2(x-1)\geq10\text{ or } 3-4x>15

Let's solve each of them individually first:

We have:

2(x-1)\geq10

Divide both sides by 2:

x-1\geq5

Add 1 to both sides:

x\geq6

We have:

3-4x>15

Subtract from both sides:

-4x>12

Divide both sides by -4:  

x

Hence, our solution set is:

x\geq 6\text{ or } x

How many solutions are there to the equation below? 12x + 32 = 12x - 7
marshall27 [118]
0 solutions

move the x to one side, and the numbers to the other.

12x (-12x) + 32 (-32)= 12 (-12x) - 7 (-32)

12x - 12x = -7 - 32

0 = -39

0 ≠ -39

∴ you have 0 solutions

hope this helps
