Answer:

45 stickers

Step-by-step explanation:

630/42 = 15 (represents the number of stickers in each pack)

Since there ar 3 packs, we multiply 15 by 3.

3 x 15 = 45

45 stickers.

Answer:

It's a probability

1 pack = x stickers

42 pack = 630 stickers

Cross Multiply

42 pack x stickers = 630 ×1 pack

= 630

Divide ( ➗) both sides by 42

x stickers = 630/ 42

x= 15

A line segment has an end point of ( -4,-6) which reflection will produce an image with endpoints (-4, 6) and (-6,-4)
HACTEHA [7]
The given point is (-4, -6)

First reflected point is (-4, 6).
Note that the x coordinate is same and y coordinate has opposite sign. Above x-axis, y is positive and below x-axis y is negative. This shows that the reflection was across x-axis which resulted in the change of sign of y coordinate.

Second reflected point is (-6, -4)
Notice that in comparison to the original point, the location of x and y coordinate has been interchanged. This can only happen when the reflection is across the line y = x. The reflection of a graph across y = x also results in the inverse of that graph, with x values and y values interchanging their positions.

So,
1st Answer: Reflection across x-axis
2nd Answer: Reflection across the line y = x

Answer:

Second option

Third option

Fourth option

Step-by-step explanation:

We have the following quadratic function

f(x) =(x-1)(x+7)

Use the distributive property to multiply the expression

f(x) =x^2+7x-x-7

f(x) =x^2+6x-7

For a function of the form f (x) = ax ^ 2 + bx + c the x coordinate of the vertex is:

x =-\frac{b}{2a}

Then in this case the coordinate of the vertex is:

x =-\frac{6}{2(1)}

x =-3

To obtain the y coordinate of the vertex we evaluate the function at x = -3

f(-3) =(-3)^2+6(-3)-7

f(-3) =9-18-7

f(-3) =-16

Then the vertex is:  (-3, -16)

We can see in the graph that the zeros of the function are x=1 and x=-7

Then the function is decreasing from -∞ to -3 and then it is increasing from -3 to ∞

The function is positive for x and x> 1

The correct answers are:

Second option

Third option

Fourth option

Which number is irrational
alina1380 [7]

For this case, we have by definition, that an irrational number is a number that can not be expressed as a fraction \frac {a} {b}, where a and b are integers and b is nonzero.

Some examples are:

\sqrt {2}, \sqrt {3}, e, \pi.

So, that the answer is \pi.

Which choice is equivalent to the expression below?
eimsori [14]

Answer:

C

Step-by-step explanation:

We have the expression:

\sqrt{-100}

Rewriting this yields:

=\sqrt{-1\cdot100}=\sqrt{-1}\cdot\sqrt{100}=i\sqrt{100}=10i

Therefore, our answer is C.
