8x + (2x - 14)= 7x + 3x -14
10x -14= 10x - 14
These equations are identical, so it would be the identity property and the answer would either be identity or the fancy 'R'.
Absolute Value can’t be negative so -3 minus -4 is -7 but since absolute value isn’t able to be negative it turns into 7, the answer is A
Well it says 1 cup of sugar (S) for every 20 cookis (N) is like saying the amount of cookies(N) is increased by a factor of 20 times the cups of sugar (S) used. which can be written:
cookies(N) = 20 * cups sugar (S)
So you just get rid of the words and use the variables S and N and get
N = 20S
that is the equation. to graph it just plug in a few numbers for s and get the n. It's just like x and y but where x is S and y is N
Answer:
(x, y) = (-1/4, -3/4)
Step-by-step explanation:
1. Write as a system
2x + 2y = 14x - 2y = -2
2. Eliminate one variable by adding the equations
2x + 2y = -2
14 x - 2y = -2
3. Divide both sides by 16
16x = -4
4. Substitute the value of x into the equation.
x = -1/4
5. Solve the equation
2(-1/4) + 2y = -2
6. A possible solution is
y = -3/4
7. Check the solution
(x, y) = (-1/4, -3/4)
8. Simplify the expression
2(-1/4) + 2(-3/4) = 14(1/4) - 2(-3/4) = -2
9. The ordered pair is a solution
-2 = -2 = -2
10. (x, y) = (-1/4, -3/4)
Answer:
40
Step-by-step explanation:
(8 x 5) x 5 = ? x 5
40 x 5 = ? x 5
? = 40
