Answer:
Should be 2, -5
Step-by-step explanation:
you flip –2, 5 along y axis, then get 2, 5
then flip 2, 5 along x axis and get 2, -5
feel free to correct
1.1, 1.3, 1.5. Your just adding .2 to the number each time
Answer:
The solution is the point (0.5,-3)
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by substitution
Substitute equation B in equation A

Solve for x
Adds 5 both sides


Divide by 4 both sides

therefore
The solution is the point (0.5,-3)
<em>Verify your answer using the graph</em>
using a graphing tool
Remember that the solution of the system of equations is the intersection point both graphs
The intersection point is (0.5,-3)
therefore
The solution is the point (0.5,-3)

❖ 6 + 45 ÷ 3² = 11
Follow order of operations:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
(Note: Multiplication and division can be done in either order as well as addition and subtraction.)
There are no parenthesis in this problem so we skip to exponents. The exponent is 3² which is 3 x 3 = 9.
We then have division. 45 ÷ 9 = 5
Our last step is addition.
Add:
6 + 5 = 11
