Answer:
X2 +(-6.5) = 42.5
x = 7 or -7
Step-by-step explanation:
x2 + (-6.5) = 42.5
x2 = 49
x = 7 or -7
Answer:
x=4
Step-by-step explanation:
The two angles together are complementary, which means they add up to 90 degrees
solving for x:
9x+4x+38=90
9x+4x=13x
13x+38=90
13x+38-38=90-38
13x=90-38
13x=52
x=4
hope this helps ^D^
Answer:
- reflection over the x-axis
- translate right 2 units
- translate down 3 units
Step-by-step explanation:
Horizontal translation of the graph of a function is accomplished by replacing x with (x-h) for translation h units to the right. Vertical translation of the graph is accomplished by adding the amount of translation to the function value: f(x)+k translates the graph k units upward.
Reflection of a function over the x-axis is accomplished by changing the sign of every function value: -f(x).
<h3>Application</h3>
We observe that f(x) has been transformed by ...
- multiplying by -1 to get -f(x)
- replacing x with (x -2) to get -f(x -2)
- adding -3 to the function value to get -f(x -2) -3
The effect of these transformations is (correspondingly) ...
- reflection over the x-axis
- translate right 2 units
- translate down 3 units
__
The attached graph shows a function f(x) (red) and the transformed function (blue).
Answer:
x = 4
Step-by-step explanation:
4(2x + 5) = 52 ( divide both sides by 4 )
2x + 5 = 13 ( subtract 5 from both sides )
2x = 8 ( divide both sides by 2 )
x = 4
