Expand and simplify 4 (3a-4)

Mathematics
2 answers:
Anettt [7]2 years ago

Answer:

a=\frac{4}{3}

Step-by-step explanation:

In this situation, we need to first do the distributive property.

4 (3a-4)= 12a -16

I am assuming that the equation would be equal to zero....

12a-16=0

Add 16 to both sides

12a=16

Divide 12 to both sides

a=\frac{16}{12}

Simplify

a=\frac{4}{3}

The variables x and y vary inversely, and x = 12 when y = 6. Use the inverse variation formula, k = xy, to
I am Lyosha [343]

Answer:

D=24

Step-by-step explanation:

y inversely as x

x=k/y

By cross multiplication

k=xy

k=12*6

k=72

finding y

72=3y

y=24

For questions 13 – 15, find x so that q || r. State the converse used.
Grace [21]

Answer:

13. x = 7 ; Converse : Alternate interior angles are equal .

14.  x=12; Converse used : Linear pair

15.  x = 23; Converse: Corresponding angles are equal

Step-by-step explanation:

13.

Refer the attached figure

Given: q || r

\angle CBE =\angle DEB (Alternate interior angles )

So,  15x+3=108

15x=108-3

15x=105

x=\frac{105}{15}

x=7

So, x = 7 ; Converse : Alternate interior angles are equal .

14.

Refer the attached figure

Given q||r

\angle PQT = \angle STQ (Alternate interior angles

So,\angle PQT = \angle STQ=11x-28

Now\angle UTQ + \angle STQ = 180^{\circ}(Linear pair)

So,7x-8+11x-28=180

18x-36= 180

18x=216

x=\frac{216}{18}

x=12

So, x=12; Converse used : Linear pair

15.

Refer the attached figure

Given q||r

\angle BDC+\angle CDE = 90+2x

\angle BDE=\angle PBC(corresponding angles)

90+2x=5x+21

90-21=5x-2x

69=3x

23=x

So, x = 23; Converse: Corresponding angles are equal

At which root does the graph of f(x) = (x – 5)3(x + 2)2 touch the x axis?
LuckyWell [14K]
We have that
f(x) = (x – 5)³(x + 2)²

we know that
<span>the roots can touch or cross the x axis

</span>The way you can tell if the graph is going to cross the x-axis or just touch the x-axis is by looking at the power of the factor.

(x - 5)³ has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis.

(x + 2)² has a power of 2 which is an EVEN number. An EVEN power means that the graph will touch the x-axis.

therefore

the answer is
<span>the graph of f(x) touch the x axis for the root x=-2
</span>
see the attached figure
