Answer:
(1, 10 )
Step-by-step explanation:
Given the 2 equations
- 9x - y = - 19 → (1)
5x + y = 15 → (2)
Adding the 2 equations term by term will eliminate the y- term
- 4x + 0 = - 4
- 4x = - 4 ( divide both sides by - 4 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for y
Substituting into (2)
5(1) + y = 15
5 + y = 15 ( subtract 5 from both sides )
y = 10
solution is (1, 10 )
It is D
Descending order means that the first polynomial factor must the largest. You can tell that by looking at its degree, or the exponent. In this, 11 is the largest degree. the smallest degree is a constant, which is 4. That is why it is D.
No, his answer was not reasonable. If jeans are 24.55 and shirt is 12.25, 24.55+12.25=36.8, not 26.80
Answer:
200
Step-by-step explanation:
130 = 0.5m + 30
subtract 30 from both sides
100 = 0.5m
divide 0.5 from both sides
200 = m
