The graph of f(1/2x) is a horizontal expansion of the graph of f(x) by a factor of 2. The mapping rule is (x, y) -> (2x, y)
                               (-4,2) -> (-8,2)
                               (-2,-2) -> (-4,-2)
                               (0,0) -> (0,0)
Plot those points to get the graph of f(1/2x).

Simplify both sides of the equation(-1.3x+-7.4x)+(7)=(1.5x+-6x)+(9)

-10.5x+7=-4.5x+9

Add 4.5 to both sides
-6x+7=9

Subtract 7 from both sides
-6x=2

Divide both sides by -6

x= -1/3

ok so if you have 3 and 1/4 pizza and want to subtract 3/4 out of it,and get 3x more slices then you had from a friend after sub

Brilliant_brown [7]

Answer:

You have 2 and 1/2 pizzas and your friend has 5/6 of a pizza.

Step-by-step explanation:

You have 3 1/4 pizzas. If you get rid of 3/4 of a pizza, you will end up with 2 2/4 pizzas.

To make it easier, you can just change the values into improper fractions: 3 1/4 = 13/4

13/4 - 3/4 = 10/4

10/4 = 2 2/4 pizzas

(2 2/4 = 2 1/2)

Anyways! You now have 2 and a half pizzas. You have 3 times the amount of pizza that your friend has. In other words, your friend has 1/3 the amount of pizza that you have. You can solve for this in two ways, whichever way you solve it is up to you.

You can solve this problem by dividing the amount of food you have by 3: $\frac{2\frac{1}{2} }{3}$ which equals 0.8333... (the 3 is repeating). But you can just keep your final answer in fraction form if you want to: $\frac{2.5}{3} = \frac{5}{6}$
You can solve this problem by multiplying 1/3 to the amount of food you have: $\frac{1}{3} * 2 \frac{2}{4}\\=\frac{10}{12}\\ =\frac{5}{6}$

You have 2 and 1/2 pizzas and your friend has 5/6 of a pizza.

Write and equivalent expression for 24x+16

Alexxandr [17]

Answer:

$8[3x+2]$

Step-by-step explanation:

we have

$24x+16$

we know that

$24=(2^{3})(3)$

$16=(2^{4})$

substitute

$(2^{3})(3)x+(2^{4})$

Factor 2^3

$(2^{3})[(3)x+(2)]$

$8[3x+2]$

A blimp is flying at a speed of 40mph and going in a direction of 80 degrees. After 3 hours of flying it turns and travels 1 hou

kykrilka [37]

Bearing is a topic that can be used to locate the position of an object at a given time. Therefore, the blimp is 80 m far away from its starting point. And in the North-East direction.

The speed of an object relates the distance it covers to the time taken to cover the said distance.

i.e speed = $\frac{distance}{time taken}$
