Answer:

x = -7/2

Step-by-step explanation:

-3(4x + 9) = 15

Divide 3 on both sides

-3(4x + 9) /3 = 15 /3

Which makes

4x+9=-5

Subtract 9 on both sides

4x+9 -9 = -5 -9

Which makes

4x=-14

So we divide 4

4x /4 = -14 /4

And we get......

x = -7/2

I hope it's right!

Which type of triangle has one angle with a measurement greater than 90°?

masya89 [10]

Answer:
Obtuse-angled triangle

Explanation:
Triangles can be classified based on the measures of their angles as follows:
1- Right-angled triangle: Triangle that has one of its angles = 90°
2- Acute-angled triangle: Triangle that has all of its angles less than 90°
3- Obtuse-angled triangle: Triangle that has one of its angles greater than 90°

The attached image shows an obtuse-angled triangle. We can note that measure ∠B is greater than 90°

Hope this helps :)

If the parent function is fx) = x^3 which transformed function is shown in the graph?

34kurt

Answer:

g(x) = (x-3)³ is the transformed function.

Step-by-step explanation:

Horizontal shift:

If f(x) is the parent function.

Then horizontal shift can be expressed as:

, will shift left units.

$y = f(x - c)$ , will shift $f(x)$ right c units.

Given the parent function

f(x) = x³

From the graph, it is clear that the transformed function is indicating that the parent function has been horizontally shifted right 3 units.

Therefore, according to the rule, $y = f(x - c)$ :

g(x) = (x-3)³ is the transformed function.

From the graph,

The Red graph indicates the parent function i.e. f(x) = x³

The Blue graph indicates the transformed function i.e. g(x) = (x-3)³

It is clear that the blue graph is obtained when the parent function has been horizontally shifted right 3 units.

Therefore, g(x) = (x-3)³ is the transformed function.

What does 1/4 of a can of coffee cost if 4 cans of coffee cost $1.60

Arte-miy333 [17]

We know that 4 cans of coffee cost $1.60. So, if we divide that number by 4, we get

$4\text{ cans of coffee} = 1.60 \iff \dfrac{4\text{ cans of coffee}}{4} = \dfrac{1.60}{4} \iff 1 \text{ can of coffee} = 0.4$

Now we can simply repeat this process again: if we divide both sides by 4, we get

$1 \text{ can of coffee} = 0.4 \iff \dfrac{1 \text{ can of coffee}}{4} = \dfrac{0.4}{4} \iff \dfrac{1}{4}\text{ cans of coffee} = 0.1$
