Answer:
[tex]x=\frac{b-ac}{a+2} ; a\neq -2[/tex]
Step-by-step explanation:
Multiply both sides: by x+c
a(x+c)=[tex]\frac{b-2x}{x+c}[/tex] (x+c)
Simplify: a(x+c)=b-2x
Expand: ax+ac=b-2x
Subtract ac from both sides: ax+ac-ac=b-2x-ac
Simplify: ax=b-2x-ac
Add 2x to both sides: ax+2x=b-2x-ac+2x
Simplify: ax+2x=b-ac
Factor ax+2x: x(a+2)
x(a+2)=b-ac
Divide both sides by a+2: [tex]\frac{x(a+2)}{a+2}[/tex] = [tex]\frac{b}{a+2}[/tex] - [tex]\frac{ac}{a+2}[/tex] ; a≠-2
Simplify: [tex]x=\frac{b-ac}{a+2} ; a\neq -2[/tex]

how do i find the x and y intercepts of x+y-5=0
Answer:
To find x intercept. Substitute y=0 in the given equation, and solve for x . x−0=5. x=5. Therefore, x intercept =(5,0)
To find y intercept. Substitute x=0 in the given equation, and solve for y . 0−y=5. y=−5. Therefore, y intercept =(0,−5)
Step-by-step explanation:
Answer:
y intercept = -5
x intercept cordinate= (5,0)

Select the statement that describes this expression: 13 + fraction 1/2 x (6 ÷ 2 + 6)
A) 13 more than half of 6 more than the quotient of 6 and 2
B) 13 more than half of the quotient of 6 and 6 minus 2
C) Half of 13 multiplied by the quotient of 6 and 2 plus 3
D) 13 plus half of 6 divided by 2, then subtract 6
Answer: It's A.
Step-by-step explanation:
I did the test and I got it right
The expression should be described option A. A) 13 more than half of 6 more than the quotient of 6 and 2
Description of an expression:
Since the expression is 13 + fraction 1/2 x (6 ÷ 2 + 6)
So we can explained that 13 should be more than the half of 6 i.e. more than the quotient of 6 and 2.
Therefore, the option A is correct.
And, the rest of the options are wrong.

-3(y+4)+4y
Please ANSWER FAST!!!!!
Answer: y-12
Step-by-step explanation:
-3(y+4)+4y
first distribute teh -3 to the y and the 4, so you get -3y and -12. Then combine like terms. -3y-12+4y, add the -3y and 4y, you get y. So the answer is y-12.
Answer:
y = 12
Step-by-step explanation:
here's your solution
=> -3(y + 4) + 4y = 0
=> -3y -12 +4y = 0
=> y -12 = 0
=> y = 12

A train left for Houston, and 5 hours later, a car traveling 74 mph tried catching up to the train. After
8 hours, the car caught up. What was the train's average speed?
Answer:
45.538 mph
Step-by-step explanation:
v = d/t (velocity = distance/time)
74 mph = d/8
d = 592 miles
[tex]v_{train}=\frac{592 miles}{5+8 hours}[/tex]
= 45.538 mph

Answer:
m = 8
k = 7
Step-by-step explanation:
Remark
Unless this really is a parallelogram, it is not (easily) solvable. I think you likely intend it to be a parallelogram, so it has an easy solution. The diagonals bisect each other.
So m = 8 because the intersect point of the diagonal and the second one makes the two parts equal.
k + 4 = 11 Subtract 4 from both sides.
-4 -4
k = 7

What is the smallest possible number of learners in the class
Answer:
30
Step-by-step explanation:
Find the lowest number divisible by both 6, 5, and 2.
To start, let's list off the numbers divisible by six, and see if we can check any of them off for 5. Since both 2 and 6 are even numbers, we know that if a number is divisible by 6, it's divisible by 2.
6 12 18 24 30 36 42 48 54 60
All of these numbers are divisible by two. Let's find the lowest one that is divisible by 5. We know this by either the umber ending in 5 or 0.
30 is the lowest number that is divisible by 2, 5, or 6.
