A) We can pick any two values from the table then can subtract initial value from final value divide by the number of instance which will give us the rate of change.
b) Same with the graph, we take two coordinates and then apply in the formula:
slope (m) = y2-y1 / x2-x1
c) We can write the equation, by substituting into the formula:
y - y1 = m (x - x1)
Where y-interecpt & slope is most important
d) When, we completely solve the equation, then it gives y-intercept, and first value of the path in the graph is known as initial value
e) In linear interval, difference between any two instances must be same, 'cause they follow the rule of proportionality whereas in non-interval, differnce will be different in magnitude
Hope this helps!
Answer:
he would have to sell 30 cakes
Step-by-step explanation:
if you take the amount it actually cost to make it and the amount he is selling them for you would first do
1.80 - 3.00 = 1.20$
after you get 1 dollar and 20 cents you would divide it by 36 dollars to get 30
to check your answer do 30 x 1.20 = 36.00
Answer:
No, this isn't a right triangle.
Step-by-step explanation:
First of all, the hypotenuse is the longest side (in this case that is 50), so that's what we're working for.
The formula for the Pythagorean theorem is :
14 squared equals 196, and 28 squared equals 784. Add these and you get 980. The square root of 980 is not 50, so we know that this is not a right tryangle.
