Answer:
x=8
Step-by-step explanation:
x+6=2x-2
8=x
Answer:
A
Step-by-step explanation:
Because 45 + 2x = 180 divide it by 2 gives 4
Answer: <u><em>pls mark as brainliest</em></u>
2x+3y>-3
First we forget the inequality sign
2x+3y=-3
Then we solve for y
3y = -3-2x
3y=-2x-3
y=-\frac{2x}{3}-1
which is of the form y =mx +b
So here slope m is 2/3 and y intercept is -1 .
First we graph .
And then we have to check, which part need to be shaded . And for that , we take a testing point. Let it be (0,0) .
Now we plug this point in the given inequality that is 2(0)+3(0)>-3
0+0>-3
0>-3 which is true. SO we have to shade that part of the graph where point (0,0) belongs .
Step-by-step explanation:
Yay
directix x=5
that means the parabola opens left or right
the equation is
(y-h)²=4p(x-h)
alrighty
vertex is (h,k)
p is distance from focus to vertex
also distance from vertex to directix
if p>0 then the parabola opens to the right and focus is to the right of directix
if p<0 then the parabola opens to the left and focus is to the left of directix
alrighty
the distance between directix and focus divided by 2=p
hmm, note which one is to the left or right of which
directix is x=5
focus is (2,-3) where x=2
focus is to the left of directix
alrighty
fro m 5 to 2 the distance is 3
3/2=1.5
and since the focus is to the left of the directix, it is -1.5
so the parabols opens to the left
the vertex is 1.5 untis to the right of the focus
so vertex is at (3.5,-3)
so
equation is
(y-(-3))²=4(-1.5)(x-3.5)
(y+3)²=4(-1.5)(x-3.5)
