Answer:
-7w
Step-by-step explanation:
-2w - 5w are like terms because they both have "w"
-2 - 5 = -7
Answer:
x = 61, y = 29
Step-by-step explanation:
29+x = 90
x = 61
x + y = 90
y + 61 = 90
y = 29
The slope is change in "Y" divided by the change in "x"
1-(-3)/2-(-1)
= 4/3
Standard Form
y-y1=m(x-x1)
y-(-3)=4/3(x-(-1)
y+3=4/3x+4/3
y=4/3x-5/3
Rewrite in standard form
-4/3x+y=-5/3
Can't have fractions so multiply by 3 to get rid of the denominator
-4x+3y=5
Divide by -1 to get rid of the negative sign
4x-3y=-5
In Step 1, I used my straightedge to draw my first line segment. Using the straightedge is key to making a perfect line, so no mistakes will result from a messy line.
In Step 2, I named my two points. It is important to name your points so you do not get confused.
In Step 3, I used my compass to measure the exact width of line AB. I did this because I know later I will need to to create the copy line.
In Step 4, I drew a ray. I know the ray doesn't have to be perfect yet so I eyeballed the length. I named the starting point C.
In Step 5, I placed the compass that had the measurements from the original line on the new ray. I did this because I need to find the new point for the new line segment.
In Step 6, I used the compass to draw an arc. I drew the arc to show where the new point should go on the ray.
<span>Lastly, in Step 7 I put the new point on the line segment and named it D. </span>
Answer:
-9x +6
Step-by-step explanation:
The usual statement of the distributive property tells you how this works:
a(b + c) = ab + ac
-1(9x -6) = (-1)(9x) +(-1)(-6) = -9x +6
