The four-fifths of a number, in this case, z is four times the number divided by z. That is 4z/5. When we add six to the product and equate the expression to 8, we get,
4z/5 = 8
The value of z from the equation is 10.
Answer:
When you plug in the coordinate into the equation, the equation becomes false.
Step-by-step explanation:
Step 1: Define
y = 3x + 1
(4, 1)
Step 2: Substitute and Evaluate
1 = 3(4) + 1
1 = 12 + 1
1 ≠ 13
Answer:
Step-by-step explanation:
Daisy looks at the inequality and says I subtract from 12 and want a result that is bigger than 5.
This means that subtracted number should be smaller than .
Thus, the solutions to the inequality are all values of such that
You can solve the inequality in following way:
Answer:
x + y = - 3.6
2x - z = 1
x + y + z = - 3.8
y - x = - 4.4
Step-by-step explanation:
We have to evaluate the given expressions of x, y, and z where, , y = - 4 and z = - 0.2.
So, x + y = 0.4 + (- 4) = - 3.6
And, 2x - z = 2(0.4) - (- 0.2) = 1
And, x + y + z = 0.4 - 4 - 0.2 = - 3.8
Finally, y - x = - 4 - 0.4 = - 4.4 (Answer)
