Are these equations equivalent? 0.8x + 3= 1.8x and 2x =6

1 answer:

leonid [27]3 years ago

6 0

Answer:

Yes

Step-by-step explanation:

0.8x + 3 = 1.8x

3 = 1.8x - 0.8x

x = 3

And:

2x = 6

dividing both sides by 2:

x = 3.

hence the two equations are equivalent since they give the same answer.

The axis of symmetry for a function in the form f(x) = x2 + 4x − 5 is x = −2. What are the coordinates of the vertex of the grap

Studentka2010 [4]

Answer:

D) $(-2,-9)$

Step-by-step explanation:

<u>Vertex Form of a Vertical Parabola:</u>

$y=a(x-h)^2+k$

Vertex -> $(h,k)$

Axis of Symmetry -> $x=h$

Vertical Scale Factor -> $a$

To turn $f(x)=x^2+4x-5$ into vertex form, we need to complete the square on the right side
Therefore, if $f(x)=0$ , then $0+9=x^2+4x-5+9$ completes the square on the right side
This becomes $9=(x+2)^2$
This means that our function in vertex form is $f(x)=(x+2)^2-9$

Therefore, the vertex of the graph is $(h,k)=(-2,-9)$ .

pav-90 [236]

Answer:

Shares of Igor Stravinsky car tires in United state = 8%

Shares of Igor Stravinsky truck tires in United state = 46.15%

Step-by-step explanation:

We have given,

Approximate yearly sales of Igor Stravinsky car tires = 3,760,000

Approximate yearly sales of Igor Stravinsky truck tires = 1,200,000

Also,

Every year about 47,000,000 care tires and 26,000,00 truck tires are sold in the United States.

Shares of Igor Stravinsky car tires in United state = $\frac{3,760,000}{47,000,000} * 100$ = 8%

Shares of Igor Stravinsky truck tires in United state = $\frac{1,200,000}{26,000,00} * 100$ = 46.15%
