Answer:
x = 3, y = - 2
Step-by-step explanation:
By substitution method,
4x + y = 10 -------> equation 1.
7x + 2y = 17 -------> equation 2.
From equation 1,
y = 10 - 4x ------> equation 3.
Substitute equation 3 in 2,
7x + 2 ( 10 - 4x ) = 17
7x + 20 - 8x = 17
7x - 8x = 17 - 20
- x = - 3
x = 3
Substitute x = 3 in equation 1,
4 ( 3 ) + y = 10
12 + y = 10
y = 10 - 12
y = - 2
Hence,
x = 3
y = - 2
Answer:
X-Intercept = (1,0) and (3, 0)
Y-Intercept = (0, 6)
Vertex = (2, -2)
Maximum or Minimum = It is minimum, the vertex is the lowest number.
Axis of Symmetry = x = 2
Zeros = (1, 0) and (3, 0)
Domain = all real numbers
Range = y ≥ -2
You would be right with 26 because the absolute value of -30 is 30 then you subtract 56-30 and get 26 which is the remaining temp you need to get to 56.
