Answer:
13
Step-by-step explanation:
because it won't 10 then 16 so I would assume 13
3.
-4(-5 - b) = (1/3)(b + 16)
distribute
20 + 4b = (1/3)b + 16/3
reduce
13/3b = -44/3
divide
b = -44/13
4.
(3/5)(t + 18) = -3(2 - t)
distribute
3/5t + 54/5 = -6 + 3t
reduce
84/5= 12/5t
divide
7 = t
I hope this helps :)
Answer:
First, let's address the general case.
When we have two points (a,b) and (c,d)
The distance between those points can be written as:
D = √( (a - c)^2 + (b - d)^2)
In this case, the points are:
(-2,4) and (2,4)
Then the distance is:
D = √( (-2 - 2)^2 + (4 - 4)^2) = √(-4)^2 = 4.
The equivalent expression to this is: |-2| + |2|
because:
I-2I = 2
I2I = 2
I-2I + I2I = 2 + 2 = 4.
This is similar to the question before. Remember that the height of a triangle is drawn 90 degrees from the base (see the little square), meaning that the height is 6.9 cm. And the base is the line the triangle is standing on ( which is 8.4 cm)
Then put them into your formula base x height / 2
6.9 x 8.4 / 2 = 28.98 cm squared
Answer: <u>2x+y=-8</u> = <u>x=-1/2y-4 </u>
<u>4x-6y=-24 </u>= <u>x =3/2y-6</u>
Step-by-step explanation:
2x+y=-8 -- Step 1: Add -y to both sides.
2x+y+−y=−8+−y
2x=−y−8
Step 2: Divide both sides by 2.
2x/2=-y-8/2
<h3 />
4x-6y=-24 -- Step 1: Add 6y to both sides.
4x−6y+6y=−24+6y
4x=6y−24
Step 2: Divide both sides by 4.
4x/4=6y-24/4
