Y = 4
When y = 0 the line falls on the x axis, so when y = 4, it will move up 4 spaces and be parallel to the x axis.
Hope this helps!!

Y= 4, because the line is graphed horizontally

How do I find the answer?

seraphim [82]

Answer:

Step-by-step explanation:

Formulas for area: Parallelogram= Base * Height

Triangle= Base * Height / 2

1st triangle to the left: 8*6=48/2=24

2nd triangle to the right:

<u>1st step: </u>6²+b²=10²

36-36+b²=100-36

√b²=√64²

b=8

2nd step: 6*8=48/2=24

only parallelogram:

6*8=48

Final step: 24+24+48=96

How do i complete these patterns

Ghella [55]

For a, each time it is taking away 2 places. 3,400,000, taking away 2 zeros is 34,000. Like they have in the example. So you need to take away 2 places for the first blank. For the second blank you need to move the decimal place 2 places to the left. For b, it's taking away 1 place, so do the same thing but with one place. For the first blank, add a place.

Select the correct answer from each drop-down menu. Shape I is similar to shape II. The sequence that maps shape I onto shape II

AURORKA [14]

Answer:

Scale factor 2.

Step-by-step explanation:

The vertices of shape I are (2,1), (3,1), (4,3), (3,3), (3,2), (2,2), (2,3), (1,3).

The vertices of shape II are (-4,-2), (-6,-2), (-8,-6), (-6,-6), (-6,-4), (-4,-4), (-4,-6), (-2,-6).

Consider shape I is similar to shape II. The sequence that maps shape I onto shape II is a 180 degree clockwise rotation about the origin, and then a dilation by a scale factor of k.

Rule of 180 degree clockwise rotation about the origin:

$(x,y)\rightarrow (-x,-y)$

The vertices of shape I after rotation are (-2,-1), (-3,-1), (-4,-3), (-3,-3), (-3,-2), (-2,-2), (-2,-3), (-1,-3).

Rule of dilation by a scale factor of k.

$(x,y)\rightarrow (kx,ky)$

So,

$(-2,-1)\rightarrow (k(-2),k(-1))=(-2k,-k)$

We know that, the image of (-2,-1) after dilation is (-4,-2). So,

$(-2k,-k)=(-4,-2)$

On comparing both sides, we get

$-2k=-4$

$k=2$

Therefore, the scale factor is 2.

5(-3x - 2) - (x - 3) = -4 (4x +5) + 13

S_A_V [24]

Start off by distributing the numbers into the parentheses:

5(-3x - 2) - (x - 3) = -4(4x + 5) + 13
-15x - 10 - (x - 3) = -16x - 20 + 13

(Note: It's super important to be careful when opening up negative parentheses! -(x-3) is not just - x - 3, it is actually -x + 3 since the negative is distributed in every number!)

-15x - 10 - x + 3 = -16x - 20 + 13
-16x - 7 = -16x - 7
-16x = -16x
0 = 0

There is an infinite number of solutions in this equation.

(When you get 0=0 when solving for a variable, that means that said variable will have infinite solutions, that is, any number plugged into the equation will work)
