Answer:
Value of 8x -5y + 7 is 4.
Step-by-step explanation:
Given that:
8x-5y = -3 Eqn 1
It is a true equation.
Now we have to find the value of the given expression
8x -5y + 7
Putting value of 8x-5y from Eqn 1 in the given expression
8x - 5y + 7
-3 + 7
4
Therefore,
8x - 5y + 7 = 4
Hence,
Value of 8x -5y + 7 is 4.
Answer:
Step-by-step explanation:
Answer:
x < -3
Step-by-step explanation:
This is simply an inequality. This should be fairly easy, but since it has a variable, you need to find the domain. Since -6(1) + 3 = -3, we can't do that. So what can we do? What if we use -1 for x instead? We get 9, so still no. We need to determine when the statement starts becoming true. At this point, -3 for x makes the expression equal to 21. This leads us to our answer.
CB would be equal to CK because of the CPCTC (congruent parts of congruent triangle are congruent) Theorem.
5x - 3 = 3x + 1
Add 3 to both sides.
5x = 3x + 4
Subtract 3x from both sides.
2x = 4
Divide both sides by 2.
x = 2
D) 2
