Answer:
w=13
Step-by-step explanation:
15+w=3w-11
+11 +11
26+w=3w
-w -w
26=2w
26/2=2w/2
13=w
Answer: B
Step-by-step explanation:
negative correlation so as x increases y decreases,
as population rises houses should rise, not A
as buildings rise, need more space and less trees, B is the answer
as cars rise population should rise, not C
no correlation, not D
24/42= 4/7
<span> To start divide both sides by 2 So 24/2=12 and then 42/2=21. So it would then be 12/21. Now both are divisible by 3 so you can divide each side by 3. So 12/3=4 and 21/3=7 so it would be 4/7. You can't-do anything further so that is the lowest term.</span>
<u>Answer:</u>
The correct answer option is B) x equals quantity of negative 7 plus or minus I square root of 3 all over 2.
<u>Step-by-step explanation:</u>
We are given the following quadratic equation:
Taking the constant on the same side as the variable to get:
Since, it cannot be factorized so we will use the quadratic formula:
x =
Substituting in the values of a, b and c in the above formula to get:
x=
x = , x =
Therefore, the correct answer option is B) x equals quantity of negative 7 plus or minus I square root of 3 all over 2.
8x + 5(-4x) = 24
8x - 20x = 24
-12x = 24
x = -2
y = -4(-2)
y = 8
Therefore, the point of intersection is (-2,8).
