For question number 2, the answer is A 6x+9

Explanation:

$\begin{gathered} 3(2x+3) \\ \text{Clearing the brackets, we get} \\ 6x+9 \end{gathered}$

Question Number 19:

$\begin{gathered} 8x-2x+4 \\ 6x+4 \\ \text{Factorizing, we get} \\ 2(3x+2) \end{gathered}$

So, the correct answer for question number 19 is 6x + 4.

A. 4*1 - 3*2 = 4 - 6 = -2 (X
B. 4*4 - 3*2 = 16 - 6 = 10 (O
C. 4*7 - 3*6 = 28 - 18 = 10 (O
D. 4*4 - 3*(-3) = 16 + 9 = 25 (X

so the answers are B and C

Suppose you know a certain parabola has a vertex of (2, 1) and a y-intercept of 4. By symmetry, you can conclude that the parabo

kodGreya [7K]

Answer:

Step-by-step explanation:

We are given a parabola with a vertex point of (2, 1) and a y-intercept of y = 4.

And we want to determine another point on the parabola.

Recall that a parabola is symmetric along the axis of symmetry, which is the x-coordinate of the vertex.

Note that since the y-intercept of the parabola is y = 4, this means that a point on our parabola is (0, 4).

To get from (2, 1) to (0, 4), we move two units left and three units up.

Since the parabola is symmetric along axis of symmetry, another point on the parabola will be two units right and three units up. This yields (2 + 2, 1 + 3) or (4, 4).

Our answer is A.

The measure of ∠1 = 188 172 94

yanalaym [24]

Answer: Third option is correct.

Step-by-step explanation:

Since we have given that

There is a cyclic quadrilateral.

As we know that "Sum of opposite angles in a cyclic quadrilateral is supplementary.":

so, it becomes,

$86^\circ+\angle 1=180^\circ\\\\\angle 1=180^\circ-86^\circ\\\\\angle 1=94^\circ$

Hence, the measure of ∠1 = 94°

Therefore, Third option is correct.

(01.01 MC)Which number line shows the solution to 4 + (−4)?

Rasek [7]

The solution to the statement 4 + (-4) is correctly given by the third number line.

The solution given by plot 1 is : (-4) + (-4) as both arrows points 4 units to the left.

The solution given by plot 2 is : ( 4 + 4) as both arrows points 4 units to the right.

The solution given by plot 3 is (4) + (-4) as one arrow points 4 units to the left and the other points 4 units to the right.

The solution given by the plot 4 is (-4 + 8) as one arrow points 4 units to the left and the other points 8 units to the right.

Therefore, the Number line which shows the solution 4 + (-4) is the third number line.
