Answer:
x = 2
Step-by-step explanation:
Given that the measure of segment BC must equal the addition of the measure of segment BA plus the measure of segment AC, we can write this in equation form:
BC = BA + AC
then we replace them with the measure information they provide:
12 x + 4 = 7 x - 4 + 8 x + 2
and we solve for x in the equation:
12 x + 4 = 15 x - 2
subtract 12 x from both sides:
4 = 15 x - 12 x - 2
4 = 3 x - 2
add 2 on both sides
4 + 2 = 3 x
6 = 3 x
x = 6/3
x = 2
Answer:
2 seconds
Step-by-step explanation:
The height of the object is modeled by the expression -16 + 8t.
It means we have
Now, when the object hits the ground, the height must be zero.
Hence, substitute h = 0 in the above equation
Therefore, it will take 2 seconds to hit the ground.
Linear functions are in the form y=mx+b.
But the functions are in the form of y=x^4 and y-x^2=4.5.
Their exponents make them a quadratic function so it doesn't have the same rate of change. Therefore the equations are not linear. They are quadratic.
For the first one, you take the original temprature -3.0° and add -5.4° which gives you an answer of -8.4°c :)
for the second you add the amount for breakfast and lunch, then multiply by 7 days
1/5 is 2% or 0.2, therefor 2/5 is 4% or 0.4
