Step-by-step explanation:

5 negative tiles and 5 negative tiles.

The product of 2 and - 5 is shown in 'option 3' with 5 negative tiles and 5 negative tiles.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We have to given that;

The product of 2 and - 5.

After multiply, we get;

⇒ 2 × - 5 = - 10

Answer:

12h+20=M

Where H=hours babysitting and M= money made or total amount

in this case since it's only an hour the equation would be 12(1)+20=M

12*1=12 and 12+20=32 so in the one hour with homework help would give you 32=M just for one hour.

Note that the 20 never changes considering it's only the charge for helping with homework and not over an hour.

But since this only asked for an hour and never specified if it was with the homework help here's this

12h=M

Answer:

6x+1

Step-by-step explanation:

Answer:

6x+1

Step-by-step explanation:

Hi there!

We are given the following expression:
4x + 8 + 2x - 7

And we want to simplify

When we simplify, we want to combine like terms. This means that we want to add terms with the same variables together (like x), and then combine them  

If there is no variable, then we add and combine the terms that don't have any variable together as well

Please note that we cannot combine terms with different variables (so if you had x+y, then it would stay as x+y).

In this case, we have 4x + 8 + 2x - 7

4x and 2x are like terms; they have the same variable (x). If we add them together, the result is 6x

8 and -7 are also like terms; they both don't have a variable. If we add (or rather, subtract) these terms, the result is 1.

Now we add 6x and 1 together, which would be 6x+1 (1 doesn't have a variable after it, so we can't combine it with 6x).

6x+1 is our answer.

Hope this helps!

The function of the baseball is a quadratic function

The baseball hits the ground after 7.7 seconds

The function is given as:

h(t) = -16t^2 + v0t + h0

Where:

v0 = 0 --- the initial velocity

h0 = 952 -- the height of the skyscraper

So, we have:

h(t) = -16t^2 + 952

When the baseball hits on the ground, h(t) = 0.

So, we have:

-16t^2 + 952 = 0

Collect like terms

-16t^2 =- 952

Divide both sides by -16

t^2 =59.5

Take the square root of both sides

t =7.7

Hence, the baseball hits the ground after 7.7 seconds

Step-by-step explanation:

D and E are right.

==================================================

Explanation:

The domain is the set of all real numbers because we can replace x with any real number we want to get some y output. There isn't any restriction on x. We don't have to worry about dividing by zero for instance. This is why choice A is one of the answers.

The range is restricted however. The largest value we can make in the range is y = 0. The graph of y = -4x^2 shows a parabola that opens upside down. The highest point is at (0,0). So that's why choice D is the other answer.

Answer:

x = 95 , y = 147 , z = 128

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the two opposite interior angles.

x is an exterior angle of the triangle , then

x = 45 + 50 = 95

vertex of triangle ( with x in it ) = 180 - 95 - 52 = 180 - 147 = 33

the vertex and y are adjacent angles on a straight line and sum to 180 , then

y = 180 - 33 = 147

z is an exterior angle of the triangle , then

z = 95 + 33 = 128

Answer:

8.5

Step-by-step explanation:

First we need to know the formula is BxH/2 for triangles. First we would do 68x2=136. Then we would do 136/16 which would give you 8.5! Hope this helps!

A triangle having area of 68 ft and a height of 16 ft, the length of the base for a triangle is, 8.5 ft

An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².

Given that,

a triangle has an area of 68 ft

a height of 16 ft

the length of the base​ = ?

Area of triangle = 1/2×base×height

                    68 = 1/2×base×16

                base =  8.5 ft

Hence, the length of the base is 8.5 ft
