Answer:
I think you meant for the plus sign in the second problem to be an = sign so the equation looks like this y=-x+4
If so your answer is A the first graph
I graphed it on desmos calculator
Answer:
a = 15
b = -10
Step-by-step explanation:
Here, we want to solve the system of linear equations
Firstly, let us multiply the first equation through by 10
2a - 5b = 100 ••••(i)
from the second equation;
a = 29 + b
Substitute this into i
2(29 + b) - 5b = 100
58 + 2b -5b = 100
-3b = 100-58
3b = 42
-b = 42/3
-b = 14
recall;
a - b = 29
a - (-14) = 29
a + 14 = 29
a = 29-14 = 15
A equals 54
im thinking b equals 12 but i could be wrong
a is right though
A quadratic function is one of the form f(X)=ax^2+bx +c,where a,b and c are numbers with 'a' not equal to zero.
The graph of a quadratic function is a curve called a parabola. Parabola may open upward or downward and vary in 'width' or 'steepness' , but all have the basic "U" shape.
All parabolas are symmetric with respect to a line called the axis of symmetry. A parabola intersects its axis of symmetry at a point called the vertex of the parabola.
You know that the two points determine a line. This means that if you are given any two points in the plane,then there is one and only one line that contains both points.
Hope this was helpful...!!!
