(Solving for a). b=(4*a)-3/4

Mathematics
1 answer:
Andrei [34K]3 years ago
8 0

Answer:

a = 3/28

Step-by-step explanation:

<em>To start solving for a variable, you need to isolate it.</em>

-4/3b = 4a

<em>-4/3 divided by 4 equals -4/12 or </em><em>-1/3</em>

a = -1/3b

<em>To completely solve for </em><em>a</em><em> we need to plug it back in and solve for </em><em>b</em><em>.</em>

b = (4(-1/3b)) - 3/4

b = -4/3b - 3/4

7/3b = -3/4

b = -9/28

<em>Finally, we can plug </em><em>b</em><em> back in to the previous equation we got for </em><em>a</em><em> to solve for </em><em>a</em><em>.</em>

a = -1/3(-9/28)

a = 3/28

<em>Furthermore, we can check if this is correct by plugging in </em><em>3/28</em><em> for </em><em>a</em><em> into the original problem and see if we get what we got for </em><em>b</em><em> (</em><em>-9/28</em><em>)</em>

Find the distance between (5, -4) and (-1, -2)
Arisa [49]

Answer: The distance is sqrt(40).

Step-by-step explanation:

Let's use the Pythagorean Theorem (a^2 + b^2 = c^2)

(Look at the image I attached)

Let's set a = 2 and b = 6. The mystery side is c, which is opposite to the right angle that is formed when you draw perpendicular lines from each of the points.

(2)^2 + (6)^2 = c^2 <--- First, we need to simplify

4 + 36 = c^2

40 = c^2 <--- Now, we need to take the square root of both sides.

c = sqrt(40)

So, the distance between (5, -4) and (-1, -2) is sqrt(40). I recommend looking at some videos on Khan Academy if you need more help! Let me know if you want me to attach a link that you can visit.
