Answer:
The solution for x would be 4.
Step-by-step explanation:
2x - 1 = 7
The value of x is unknown, but you do know that you are multiplying 2 by x. So, if you rewrite the equation as 7+1=2x, you know that 8=2x. If you then divide both sides by 2, you're left with 4=x which would mean that the variable x has a solution of 4
4. The range of a relation is given -3, 2, 0, 13, 17 Which domain makes the relation not a function? A. 0, 1, 2, 3, 4 B. 1,1, 2,
faust18 [17]
The domain that makes the relation not a function is c
Use y=-3x+5 on this equation 5x-4y=-3
5x-4(-3x+5) = -3
5x+12x-20 = -3
17x=17
x=1
y=-3x+5
for x=1;
y=-3+5
y=2

Step-by-step explanation:
just add the recurring bar on top of the 3 and it should be correct
The value of unknown number n is 47, wrote by Ms. Morales.
<h3>What is defined by the term expression?</h3>
In mathematics, an expression is a sentence that contains at least two digits or variables and with at least each math operation.
Addition, simple arithmetic, multiplication, or division are all examples of math operations.
- a) Constant: a numerical value that is fixed.
- b) Variables: they have no fixed values. Values are assigned based on the requirement.
- c) Terms: could be constants, variables, or variables multiplied by constants/ (s). Each word in an expression is denoted by a '+' or '-' sign.
For, the given condition in question;
Ms. Morales wrote the sum of 5 copies of some number n.
Then again,
He again wrote 2 copies of the same unknown number n.
The expression becomes;
n = 42 + 5
n = 47
Thus, the value of the unknown value is found as 47.
