Intro:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

The quickest way to do this is to look how much it goes down and then how much it goes left. This is called rise over run. So the line goes 2 down then left 3 to get from one perfect point to another.

So the answer is Choice D. It went down 2 so it's negative.

Find the missing terms in the following sequence 2,4,8,16,30, , , , 186,

ivann1987 [24]

Are you sure it is correct because for each one your just doubling the number. 2+2=4. 4+4=8. 8+8=16. I think its suppose to be 16+16= 32 and so on, but I may be wrong

A line joins the point

Harrizon [31]

Intersection of the first two lines:

$\begin{cases}5x - 2y + 3 = 0\\4x - 3y + 1 = 0\end{cases}$

Multiply the first equation by 4 and the second by 5:

$\begin{cases}20x - 8y + 12 = 0\\20x - 15y + 5 = 0\end{cases}$

Subtract the two equations:

$(20x - 8y + 12)-(20x - 15y + 5)=0 \iff 7y+7=0 \iff y=-1$

Plug this value for y in one of the equation, for example the first:

$5x - 2\cdot (-1) + 3 = 0\iff 5x+5=0 \iff x=-1$

So, the first point of intersection is $(-1,-1)$

We can find the intersection of the other two lines in the same way: we start with

$\begin{cases}x=y\\x=3y+4\end{cases}$

Use the fact that x and y are the same to rewrite the second equation as

$x=3x+4 \iff 2x=-4 \iff x=-2$

And since x and y are the same, the second point is $(-2, -2)$

So, we're looking for a line passing through $(-1,-1)$ and $(-2, -2)$ . We may use the formula to find the equation of a line knowing two of its points, but in this case it is very clear that both points have the same coordinates, so the line must be $y=x$

In the attached figure, line $5x - 2y + 3 = 0$ is light green, line $4x - 3y + 1 = 0$ is dark green, and their intersection is point A.

Simiarly, line $x=y$ is red, line $x = 3y + 4$ is orange, and their intersection is B.

As you can see, the line connecting A and B is the red line itself.

Pemdas? thank you!<br>(-12 ÷ 3) × 2 + 23<br>

$( - 12 \div 3) \times 2 + 23 =$

$( - 4) \times 2 + 23$

$- 8 + 23 =$

$23 - 3 - 5 =$

$20 - 5 = 15$

Which is the equation of a line parallel to the line with the equation y= 1/4x +2

natta225 [31]

Answer:

Any line with slope 1/4 like y=1/4x -5.

Step-by-step explanation:

Parallel lines never cross and therefore have the same exact slope. Since slope intercept form is y=mx+b and m is slope, then y=1/4x+2 has a slope of 1/4. Any line with a slope of 1/4 will be parallel. Example: y=1/4x - 5
