Answer:
(2, 5)
Step-by-step explanation:
Given the 2 equations
y = x + 3 → (1)
- 2x + y = 1 → (2)
Substitute y = x + 3 into (2)
- 2x + x + 3 = 1
- x + 3 = 1 ( subtract 3 from both sides )
- x = - 2 ( multiply both sides by - 1 )
x = 2
Substitute x = 2 into (1) for corresponding value of y
y = 2 + 3 = 5
Solution is (2, 5)
Answer:
x = 13
Step-by-step explanation:
Using the sine ratio with the 45° angle on lower left and the exact value
sin45° = 
ain45° = 
= 
= ( cross- multiply )
x = 13
Answer:
y = 2x - 7
Step-by-step explanation:
Use desmos easy and you understand how graphs work
Count how many times you have to move the decimal point to move it past the first number. in this case 6, so...
1.84*10^-6 is the answer.
Hope this helps! :)
