One and a half = 1.5
Three and a half = 3.5
1.5 + 3.5 = 5.
Answer:
x = 26
Step-by-step explanation:
m<RTS = 4x - 14 (given)
Based on the inscribed angle theorem, the measure of the inscribed angle in a semicircle = right angle (90°)
Therefore,
4x - 14 = 90
4x - 14 + 14 = 90 + 14 (addition property of equality)
4x = 104
4x/4 = 104/4
x = 26
Answer:
slope=1
y-int=-8
Step-by-step explanation:
2 / 3 ( y + 57 ) = 178
2( y + 57 ) / 3 = 178
2*y + 2 * 57 / 3 = 178
2y + 114 / 3 = 178
3*(2 y + 114 ) / 3 * ( 178)
2 y + 114 = 534
2y = 534 - 114
2 y = 420
y = 420 / 2
y = 210
hope this helps!
So the equation of the red graph is already given to us: 
. I assume you meant the blue graph?
We can use the vertex form: 
, where 
is the vertex. (We can ignore 
because is 1 for this graph.) Remember that the vertex is the maximum or minimum of a parabola and the point that the line of symmetry passes through. For f(x) the vertex is (0,0).
The vertex for 
is at 
on the coordinate plane. (4 left, 2 down)
Plug into the vertex form:
The double negative becomes a positive, and then you're done:
