Can you please show something, I can not solve it without something to look at, but I believe the answer may be 28.
Answer:
2 grams
Step-by-step explanation:
One can see that the given diagram is that of a balancing scale, meanig that both sides are equal to each other. Therefore, if one calls the weight of the triangle (t), then one can form an equation. Keep in mind that it is given that the square weighs (4) grams, and therefore, the square doesn't need a variable representation.
t + 4 + 4 = t + t + t + 4
Simplify,
t + 8 = 3t + 4
Inverse operations,
t + 8 = 3t + 4
-4 -4
t + 4 = 3t
-t -t
4 = 2t
/2 /2
2 = t
Answer:
A. {(8,0), (0,8), (1,-6), (4,-7), (-1,8)}
Step-by-step explanation:
Any relation that maps x to more than one value of y is NOT a function.
__
In B, -3 is an x-value that is used twice.
In C, -1 is shown as being mapped to 10 and 18 (more than one value).
In D, the graph shows -4 produces 2 different output values.
The appropriate choice is the set of ordered pairs shown in A.
DE and EF are segments of the line DF, so they will add up to DF. This can be represented with this equation:
Combine like terms:
Add 15 to both sides:
Subtract 6x from both sides:
Divide both sides by 3 to get x by itself:
The value of x will be 8.
Plug this value of x into the expression for DF:
DF will equal 57.
