Which shows the first equation written in slope-intercept form?1/2 (2y + 10) = 7x​

Mathematics
1 answer:
adelina 88 [10]4 years ago
7 0

Answer:

y = 7x - 5

Step-by-step explanation:

To write the equation in the slope intercept form, use the distributive property and rearrange the terms.  

1/2 (2y + 10) = 7x

y + 5 = 7x

y = 7x - 5

Hope this helped :)

Step-by-step explanation:

let : the pair of jeans = X

a. the equation is :

4(X-3) + 8 = 92

b. 4(X-3) = 92-8

4X -12 = 84

4X = 84+12

4X = 96

X = 96/4

X = 24

so, the price of each pair of jeans = $24

_________

For the solution x = 2.6, the left side of equation

(2x - 6) => would be 2(2.6)-6 = 5.2-6 = -8 ( the negative value),

but on the right side of the equation 4x+8 => 4(2.6) +8 = 18.4 ( the positive value)

this difference indicates that x=2.6 is not the right solution.

Which of the following shows the general formula for factoring the difference of cubes?
Tcecarenko [31]

Answer:

(a - b)(a² + ab + b²)

Step-by-step explanation:

The difference of cubes is expressed as:

a³-b³

Using trial and error:

a³-b³

Check  (a - b)(a² + ab + b²)

Expand

(a - b)(a² + ab + b²)

= a(a²)+a(ab)+a(b²)-a²b-ab²-b³

= a³+a²b+a(b²)-a²b-ab²-b³

Collect the like terms

= a³+a²b-a²b+ab²-ab²-b³

= a³-b³

Hence the required option is

If the sum of two consecutive odd number is 12 find them​
Fiesta28 [93]

Answer:

5 and 7

Step-by-step explanation:

<u>Fast and loose</u>: 12 is written as a sum of two odd numbers as 1+11; 3+9; 5+7. The only consecutive pair is 5 and 7

<u>Let's use algebra</u>: let's call 2n+1 the first and 2n+3 the second.

Their sum is 2n+1 +2n+3 = 4n+4 = 12. Thus, n+1=3 and n= 2. It means the 2 numbers are 2x2+1 =5 and 2x2+3 =7

Option B

Step-by-step explanation:

Only lines which are parallel to the line which connects the given two points will neve r intersect,

parallel line has same slope

the slope of the line which connects the given two points is, 5/2

and the line is option B also has the same slope, so those two lines will never intersect each other.

A​ T-shirt is launched from a height of 66 feet with an initial upward velocity of 6464 feet per second. The​ T-shirt is caught
dusya [7]
<span> s = -16t^2 + 64t + 3
v = -32t + 64

the maximum height occurs when v = 0:
-32t + 64 = 0 when t = 2 sec

the maximum height is
s = -16(2^2) + 64(2) + 3 = 67 ft

the range is [ 3, 67] </span>
