Answer:
- 23/13
Step-by-step explanation:
1. Subtract 5/2 from both sides of the equation.
2. Simplify
7/5 = /10 − 23/10
3. Multiply all terms by the same value to eliminate fraction denominators.
7/5 = /10 − 23/10 2 ⋅ 5 ⋅ 7/5 = 2 ⋅ 5( /10 − 23/10)
4. Simplify
14 = − 23
5. Subtract from both sides of the equation.
14 = − 23 14 − = − 23 −
6. Simplify
13 = − 23
7. Divide both sides of the equation by the same term.
13<em>x </em>= −23 13x/13 = -23/13
8. Simplify
= −23/13
Answer:
The value of k = 20 for equation 2(4x+10)=8x+k to have infinitely many solutions.
Step-by-step explanation:
Given the expression
solving
We know that the equations with infinitely many solutions have the same expressions on both sides
It means the value of k can be determined by further simplifying such as
8x+20-8x = k
20 = k
Therefore, the value of k = 20 for equation 2(4x+10)=8x+k to have infinitely many solutions.
VERIFICATION:
Given
Put k = 20 in the equation
equations with infinitely many solutions have the same expressions on both sides.
This means the statement is always true.
Answer:
(-3,4)
Step-by-step explanation:
That means to reflect the point across the y-axis... If you draw (3,4) on the coordinate plane you should see (-3,4) is the reflection across the y-axis from that point.
