Answer:
B
Step-by-step explanation:
f(x) = y = x^2 + 7
x = y^2 + 7
x - 7 = y^2
sqrt(y^2) = sqrt(x - 7)
y = +/- (x - 7)
Answer B
Answer:
D.
Step-by-step explanation:
The problem is asking to multiply x-5 by x^2, so we can set it up to distribute the x^2 to both values. The final answer would therefore be x^2(x-5), which is D.
Absolute value represents distance. Distances can't be negative.
So it's impossible to have |3-w| be some negative value.
Which is why
has no solutions
Answer:
(0,-3)
Step-by-step explanation:
2x-y = 3
x+2y = -6
Multiply the first equation by 2 so we can eliminate y
2(2x-y =3)
4x -2y = 6
Add this to the second equation
4x -2y = 6
x+2y = -6
-----------------
5x +0y = 0
x = 0
Now find t
x+2y = -6
0+2y = -6
2y =-6
Divide by 2
y = -3
Answer:
jyyj
Step-by-step explanation:
From the figure,
Radius matches with (F) that is a segment between the centre of a circle and a point on the circle.
Arc matches with (D) that is Circle A and the portion of the circle between points B and C is darkened.
Chord matches with (C) Circle A and a line segment connecting points B and C which are on the circle.
Secant matches with (E) that is Circle A and a line segment connecting points B and C which are on the circle.
Tangent matches with (A) that is a line intersects a circle in exactly one point.
Circumference matches (B) that is the distance around a circle.
