Solve this PLZ! 4 - 7 (v - 9) = -7 -6(v - 10)

1 answer:

7 0

I maybe wrong, but I think it is 14

Simplify both sides of the equation
(Do distributive property)
Add 6v to both sides
Subtract 67 from both sides
Divide both sides by -1

QveST [7]

Answer:

D. D

Step-by-step explanation:

Where -1.9 is!!

The question states the : opposite of the opposite.

So- we find the opposite of (-1.9) =1.9 and the opposite of that is = -1.9.

So- it is situated at -1.9

Hope this helps!! =)

Form quadratic functions given the following information: Zeroes at 4 and –2, f(0)=4

laila [671]

Answer:

$f(x)=-0.5x^2+x+4$

Step-by-step explanation:

we know that

A quadratic function in factored form is equal to

$f(x)=a(x-x_1)(x-x_2)$

where

a is the leading coefficient

x_1 and x_2 are the zeroes of the function

substitute the given values

$f(x)=a(x-4)(x+2)$

Find the value of a

Remember that

For x=0 ----> f(0)=4

substitute

$4=a(0-4)(0+2)$

$4=a(-8)\\a=-0.5$

$f(x)=-0.5(x-4)(x+2)$

$f(x)=-0.5(x^2+2x-4x-8)$

$f(x)=-0.5(x^2-2x-8)$

$f(x)=-0.5x^2+x+4$

Easy one - giving brainly if correct - show work.

astra-53 [7]

Answer:

47. 1 5/8

48. 1 1/12

Step-by-step explanation:

47.

First, convert the denominators to be the same.

8 1/2 minutes, Ruby's mile time, can be converted to 8 4/8.

Then subtract.

8 4/8 - 6 7/8 = 1 5/8

48.

Make sure the denominators are the same. Both denominators can be multiplied by 3 or 4 to become 12.

1 1/4 can be multiplied by 3 to get 1 3/12. And 1 1/3 can be multiplied by 4 to get 2 4/12.

Then subtract.

2 4/12 - 1 1/3 = 1 1/12

Find a formula for the general term an of the sequence, assuming that the pattern of the first few terms continues. (Assume that

sveta [45]

The formula for the general term of the sequence is Tn = 4n - 2

<h3>How to determine the formula?</h3>

The sequence is given as:

{2, 6, 10, 14, 18, . . . }

The above sequence is an arithmetic sequence with the following features:

First term, a = 2
Common difference, d = 4 i.e. 6 - 2

The formula for the general term is calculated using:

Tn = a + (n - 1) * d

This gives

Tn= 2 + (n - 1) * 4

Expand

Tn = 2 + 4n - 4

Evaluate the like terms

Tn = 4n - 2

Hence, the formula for the general term of the sequence is Tn = 4n - 2
