Answer:
The coordinates of the science lab is:
x = -14/3 , y = 1
Step-by-step explanation:
∵ P is (-8 , -1) and Q is (2 , 5)
∵ The point of the science lab is (x , y)
∵ The science lab point divided PQ at ratio 2 : 1 from Q (two thirds PQ)
∴
∴
∴
∴
∴ The point of science lab = (-14/3 , 1)
ANSWER
(–4.5, 4.25)
EXPLANATION
The first equation is
This function is in the slope-intercept form
The second equation is:
x + 2y = 4
2y =-x+ 4
The graph of the two functions are shown in the attachment.
The point of intersection represents the solution to the system of equations they represent.
The solution is
(–4.5, 4.25)
Answer:
Ahh... Tsym for that. But what is the link of that website.
Step-by-step explanation:
Please give me brainliest :)
<span>(2a + 2) / (a^2 – 1)
(2(a +1)) / (a^2 - 1)
(2(a + 1)) / (a^2 - 1^2)
(2(a + 1)) / ((a + 1)(a - 1))
2 / a - 1
The answer is: 2/a - 1.</span>
1: x + 8.23 = -5.14
Subtract 8.23 from both sides
x = -13.37
2: 4/9x = 32
Multiply both sides by 9 (basically, 4 is being divided by 9, so the opposite is to multiply).
(9 times 4, then divided by 9 is 4)
4x = 288
Divide both sides by 4 to isolate x
x = 72
