Answer:
Each term is separated by an addition or subtraction sign.
Coefficients are numbers in front of a variable (letter).
Constants are numbers with nothing else.
so you get
2 | 2 | 3 | 1
6 | 6 | 0.2, -1, 8 | 1/2
3 | -3 | - | -
Step-by-step explanation:
Answer:
C. The y-intercept of the graph is 4 so it is the smallest.
Step-by-step explanation:
A would not be correct since it has a y-intercept of 10.
B. would not be correct since it has a y-intercept of 6.
D. would not be correct since it has a y intercept of 6.
Answer:
Subtracting with zero: 0 – a = –a. Use the rule for subtracting signed numbers: Change the operation from subtraction to addition and change the sign of the second number. Likewise, a – 0 = a. It doesn’t change the value of a to subtract zero from it.
Step-by-step explanation:
Answer:
Choice 3
Step-by-step explanation:
The third fraction (third refers to the answer number) is incorrect. As written, the cups won't cancel. The correct way to do this is to invert the fraction.
4 tablespoons
===========
1/4 cup
This is an extremely important procedure to know. Make sure you understand what the basis of it is. Often times in higher physics, you don't have a proper relationships and this method (called dimensional analysis) is the only tool you have to work with.
So each term has at least 1 cancelation that occurs with the prior term. And it is the units that you look to cancel, and that determines which way to put the intermediate steps.
Answer:
The answer to your question is the height of the lamp is 18.2 ft
Step-by-step explanation:
Data
Street lamp shadow = 31.5 ft
Street sign height = 8 ft
Street sign shadow = 14 ft
Street lamp height = x
Process
1.- To find the height of the lamp use proportions. In this kind of problem, we do not look for the length, but the shadow.
Street lamp height/street lamp shadow = street sign height/street sign
shadow
Substitution
x / 31.5 = 8 / 14
Solve for x
x = (31.5)(8) / 14
Simplification
x = 254.4 / 14
Result
x = 18.2 ft
