Answer:
Step-by-step explanation:
1) y = 3x + 1
When x = -1 , y = 3*(-1) + 1
= -3 + 1
y = -2
(-1 , -2)
When x = 0 , y = 3*0 + 1
y = 1
(0 , 1)
When x = +1 , y = 3*1 + 1
= 3 + 1
y = 4
(1 , 4 )
Plot these points in the graph and join the points.
2) y = 2x -1
When x = -1 , y = 2*(-1) - 1
= - 2 - 1
y = -3
(-1 , -3)
When x = 0, y = 2*0 - 1
y = -1
(0 , -1)
When x = +1 , y = 2*1 -1
= 2 - 1
y = 1
(1 , 1)
Answer
Step-by-step explanation:
Both 1 and 2 equel up to 90 degrees
so to find x for 1 and 2 you would simplify the equations
90 = 6x - 3
and
90= 3x - 6
simplify them and you wil get the answers you want
another way to do it is combining the two and solve.
90 = 9x - 9
Just simplify :)
Answer: 3x^2 + 7x -15
I dunno if u want me to factor it tho
Sin(t)=8/17
cos(t)=-15/17
tan(t)=-8/15
sec(t)=-17/15
csc(t)=17/8
cot(t)=-15/8
Answer:
2 5/18
Step-by-step explanation:
multiply across.
