Fiona is trying to prove that a pair of expressions are equivalent by using substitution. Which pair of expressions has the same

fiasKO [112]

Missing Part of the Question

3 (4 - y) -7 ; 5 + 3y

9 + y + 4y - 2 - 3y; -2y + 7

5 + y - 2 - 6y + y; 8y + 3

2y + 7 + y - 2 + y; 4y + 5

Answer:

2y + 7 + y - 2 + y; 4y + 5

Step-by-step explanation:

Given

y = 3

Required

Which pair of expression are equal

To get the pair of expression that are equal; we simply substitute 3 for y in each of the expressions

3 (4 - y) -7 and 5 + 3y

Substitute 3 for y in 3 (4 - y) -7

This gives 3(4 - 3) -7

= 3(1) - 7

= 3 - 7

= -4

Then Substitute 3 for y in 5 + 3y

This gives 5 + 3(3)

= 5 + 9

= 14

-4 and 14 are not equal

---------------------------------------------------------------------------------------

9 + y + 4y - 2 - 3y; -2y + 7

Substitute 3 for y in 9 + y + 4y - 2 - 3y

This gives 9 + 3 + 4(3) - 2 - 3(3)

= 9 + 3 + 12 - 2 - 9

= 13

Then Substitute 3 for y in -2y + 7

This gives -2(3) + 7

= -6 + 7

= 1

13 and 1 are not equal

---------------------------------------------------------------------------------------

5 + y - 2 - 6y + y; 8y + 3

Substitute 3 for y in 5 + y - 2 - 6y + y

This gives 5 + 3 - 2 - 6(3) + 3

= 5 + 3 - 2 - 18 + 3

= -9

Then Substitute 3 for y in 8y + 3

This gives 8(3) + 3

= 24 + 3

= 27

-9 and 27 are not equal

---------------------------------------------------------------------------------------

2y + 7 + y - 2 + y; 4y + 5

Substitute 3 for y in 2y + 7 + y - 2 + y

This gives 2(3) + 7 + 3 - 2 + 3

= 6 + 7 + 3 - 2 + 3

= 17

Then Substitute 3 for y in 4y + 5

This gives 4(3) + 5

= 12 + 5

= 17

17 and 17 are equal

Hence, Option D is correct

3. 'a' and 'b' are the intercepts made

Julli [10]

Given:

'a' and 'b' are the intercepts made by a straight-line with the co- ordinate axes.

3a = b and the line pass through the point (1, 3).

To find:

The equation of the line.

Solution:

The intercept form of a line is

$\dfrac{x}{a}+\dfrac{y}{b}=1$ ...(i)

where, a is x-intercept and b is y-intercept.

We have, 3a=b.

$\dfrac{x}{a}+\dfrac{y}{3a}=1$ ...(ii)

The line pass through the point (1, 3). So, putting x=1 and y=3, we get

$\dfrac{1}{a}+\dfrac{3}{3a}=1$

$\dfrac{1}{a}+\dfrac{1}{a}=1$

$\dfrac{2}{a}=1$

Multiply both sides by a.

$2=a$

The value of a is 2. So, x-intercept is 2.

Putting a=2 in $b=3a$ , we get

$b=3(2)$

$b=6$

The value of b is 6. So, y-intercept is 6.

Putting a=2 and b=6 in (i), we get

$\dfrac{x}{2}+\dfrac{y}{6}=1$

Therefore, the equation of the required line in intercept form is $\dfrac{x}{2}+\dfrac{y}{6}=1$ .
