Answer:
-7(5-u)
Step-by-step explanation:
-7(5-u)
-7x5 -7x-u
-35+7u
Answer:
10+x+3x=-4(x-4)
10+2x=-4x+16
collect like-terms
2x+4x=16-10
6x=6
divide both by 6 to find the value of x
therefore, x is equal to 1
Answer:
choice 1) 2-4y
Step-by-step explanation:
from the answers available, you are looking for the expression for x to substitute into the first equation.
The second equation is: x+4y = 2
To convert x+4y = 2
subtract 4y from both sides of the equation:
x+4y-4y = 2-4y
simplified:
x = 2-4y
Step-by-step explanation:
B: The x axis is the horizontal one. If we look at the graph, there are actually two spots where the line crosses the x axis. It looks to be between -2 and -1 as well as 1 and 2
D: For vertical parabolas such as this, the axis of symmetry is the x coordinate of the vertex. The vertex is essentially the middle point, that, for this graph, is at the bottom. The axis of symmetry is x=0 as that is the x coordinate of the vertex.
E: f(x), in 2D graphs, is typically y, as is the case here. As this parabola opens upward, the minimum point is the vertex, which seems to be -3 for this graph. As the graph seems to be x²-3 or something like that, there is nothing limiting x from being infinity, and when x is equal to infinity in this function, y is as well. Thus, the maximum is infinity.
