Answer:
as the first answerer i did not take this yet but i can tell you the formula
slope of XY = y2 - y1 / x2 - x1
Answer= 66 degrees
All triangles add to 180 so 180-90-24= ABC
Answer:
x=-2,y=-4
Step-by-step explanation:
Substuting the value of y in second equation.
3x+3×2x=-18
9x=-18
x=-2
putting the value of x in equation 1 ,
y=-4
Answer:
f(5)=13
Step-by-step explanation:
Lets fill in the variable first. If f=5, then we need to replace all of the 'x' with 5. So, our new equation is going to be f(5)= 3(5)-2. All thats left is some simple multiplication and subtraction. 3 times 5= 15 ; 15-2= 13.
f(5)= 13
Answer:
the value at which f(x)=0 are the zeros of the function f(x). The graph of such a function will crosses x-axis at that point and the point is (x,0).
