6x to the power of 2
6x^2
Answer: 36x
This is a simultaneous question.
To solve this, we have to make up 2 equations based on the info provided like so:
electricity = e
gas = g
600e + 100g = $412 ——(1)
400e + 150g = $293 ——(2)
In this case, it’ll be easier to use the elimination method where you eliminate a variable so you can calculate only one.
Here, we will be eliminating e so we can get the cost of gas.
To do this we need to get both equation’s e to 600, so we have to multiply equation 2 by 1.5:
(2) x 1.5:
400e + 150g = $293
600e + 225g = $439.50 ——(3)
Now we eliminate e by subtracting equation 1 from equation 3:
(3) - (1):
600e + 225g - 600e - 100g = $439.50 -$412
125g = $27.50
g = $0.22.
Therefore one unit of gas costs $0.22.
Hope it helps and have a good day ahead :D
Y = -3/2x + 6....the slope here is -3/2. A parallel line will have the same slope.
y = mx + b
slope(m) = -3/2
(2,-1)...x = 2 and y = -1
now we sub and find b, the y int
-1 = -3/2(2) + b
-1 = -3 + b
-1 + 3 = b
2 = b
so ur parallel equation is : y = -3/2x + 2
Answer:
B

Answer:
9
Step-by-step explanation:
Use the Pythagorean Theorem which states
a² + b² = c²
then plug in your given terms
a² + 5.6² = 10.6²
find the squares
a² + 31.36 = 112.36
subtract 31.36 from 112.36 to find your a²
a² = 81
then find the square root of 81, which is 9 becuase 9 x 9 is 81
