Answer:
A= -17
Step-by-step explanation:
A +-21 = -38
+21 +21
-38+21= -17
A= -17
F(4)=4(4)+5
Which equals
F(4)=21
Answer:
The graph f(x)=
is a reflection over the x-axis, vertical stretch by a factor of 2, a horizontal translation left 3 units and a vertical translation 4 units down of the graph y=
.
Step-by-step explanation:
The graph f(x) is reflected over the x-axis because the negative is outside of the parenthesis.
it's a vertical stretch by a factor of 2 because 2 is outside of the parenthesis and is greater than 1.
(x+3) is a horizontal translation left 3 units because it is inside the parenthesis.
-4 is vertical translation 4 units down because it is outside of the parenthesis.
Answer:
x = 41* & y = 90.
Step-by-step explanation:
Since we know that the figure is a right triangle, we can solve for y easily, as 90+y = 180
y = 90
to solve for x, we have 49+90+x, since the angle that makes up the left side is perpendicular to the triangle,
so 139+x = 180
x = 180-139
x = 41
