Answer:
The measure of the angle will be 25°
Step-by-step explanation:
when two lines intersect each other, four angles are formed . Two of these angles are equal and the other two angles are also equal. The equality of the of these angles is due to the fact that they are vertically opposite angles.
Vertically opposite angles are equal. Since the sum of two angles formed due to the intersection of the two lines is equal to 50° , the two angles should be equal(vertically opposite angles).
The angles will be 50/2 = 25°. Each angle will be 25°. If we want to find the other 2 angles formed by the intersection we subtract 50 from 360°. we will get 310. The angles will be 310/2 = 155°. Generally the angles formed from the intersection of this 2 lines will be 25°, 25°, 155° and 155°.

Answer:
The graph is positive and decreasing for all real values of x where x < -1
Step-by-step explanation:
we have
The function is a vertical parabola open up
The roots (x-intercepts) are x=3 and x=-1
The vertex is the point (1,-4 ) is a minimum
using a graphing tool
see the attached figure
we know that
In the interval (-∞,-1) ---> the function is positive and decreasing
In the interval (-1,1) ---> the function is negative and decreasing
In the interval (1,3) ---> the function is negative and increasing
In the interval (3,∞) ---> the function is positive and increasing
therefore
The graph is positive and decreasing for all real values of x where x < -1
Answer:
The correct option is option A
Step-by-step explanation:
We have the following expression:
sqrt(18x^3) - sqrt(9x^3) + 3sqrt(x^3) - sqrt(2x^3)
We know that sqrt(a*b) = sqrt(a)sqrt(b)
Applying this, we have:
sqrt(18)sqrt(x^3) - 3sqrt(x^3) + 3sqrt(x^3) - sqrt(2)sqrt(x^3)
sqrt(x^3)[ sqrt(18) - sqrt(2)]
sqrt(x^3)[ 3sqrt(2)- sqrt(2)]
sqrt(x^3)[2sqrt(2)]
Then we now that:
sqrt(x^3)[2sqrt(2)] = 2x*sqrt(2x)
The correct option is option A
If u have a solid dot, then there is an equal sign in the inequality....if it is shaded to the right, u use a greater then sign....if it is shaded to the left, u use a less then sign
3. solid dot on -1, shaded to the right......x > = -1
4. solid dot on 5, shaded to the left.....x < = 5
