The correct answer is 3380 meters
Explanation:
The initial elevation of the hike can be represented as -20 meters, this is because the initial elevation is below the sea level, and in terms of elevation the sea level is considered to be 0. Now, using this number the final elevation can be calculated by adding the two numbers:
-20 + 3400 = 3380
This implies the final elevation has 3380 meters
You can also get this same result by considering there are 20 meters from the initial elevation to the sea level and then 3380 meters from the sea level to the final elevation (3380+20 = 3400).
Since there are already choices in the question, I suggest you just substitute in the values of x to each choice and check whether the corresponding value for y appears. This is also called the trial and error method in multiple choice.
The answer that represents the data in the table is C. <span>y = x^2 – 5.</span>
Answer:
He will get back 11 dollars.
Step-by-step explanation:
7 twenty dollar bills is just 7 x 20. That's equal to 140. Now your gonna subtract 140 - 129. You end up with 11 dollars!
Answer:
140°
Step-by-step explanation:
∠ABC is an inscribed angle and its measure is half the measure of the intercepted arc, which is arc AC
Therefore the measure of arc AC is 2(70) = 140°
∠AOC is a central angle and its measure is equal to its intercepted arc, which is arc AC.
So, m∠AOC = 140°
Answer:
y = -2x -3
Step-by-step explanation:
I love slope-intercept form! lol
y =mx +b
so we have 2 points given: (-1,5) and (4,-5)
to find the SLOPE of the slope-intercept form, we need to subtract and divide
(-5-5)/(4+1)
-10/5= -2 which is our slope
now! lets translate this info into point slope form. y - y1 = m (x - x1)
(-1,5) and we kno the slope is -2.
y - 5 = -2 (x - (-1))
y-5 = -2(x + 1)
y-5 = -2x -2
add five
y = -2x -3 we are back to slope intercept form! YAY!
