Make x the subject of the formula<br>y = mx + b​
zubka84 [21]

Step-by-step explanation:

y=mx+c

Take c from both sides:

y-c = mx

Divide both sides by m:

(y-c) / m =x

Now swap sides to make it prettier:

x = (y-c) / m

In one particular suburb, 50% of families own a pug. If there are a total of 24 families in the neighborhood that own a dog in g
Norma-Jean [14]
50% can also be written as (1/2)

Multiply the two known values:

24 x (1/2)

This is equal to (24/2). Simplify the fraction by dividing:

(24/2) = 12

12 dog owners own a pug.

I hope this helps!

Which one are these paired to the solution
Soloha48 [4]

Answer:

Option b and d.

Step-by-step explanation:

Given equation : -5x + 4y > -7

Putting the values of x and y one by one in the options,

a) Putting x as 6 and y as 4.

=> -5(6) + 4(4) > -7

=> -30 + 16 > -7

=> -14 > -7

This doesn't satisfy the inequality, hence this couldn't be the ordered pair.

Similarly,

b) Putting x as 5 and y as 5.

=> -5(5) + 4(5) > -7

=> -25 + 20 > -7

=> -5 > -7

This satisfies the inequality, hence this is the ordered pair.

c) Putting x as 3 and y as 2.

=> -5(3) + 4(2) > -7

=> -15 + 8 > -7

=> -7 > -7

This doesn't satisfy the inequality, hence this couldn't be the ordered pair.

d) Putting x as -2 and y as -4.

=> -5(-2) + 4(-4) > -7

=> 10 - 16 > -7

=> -6 > -7

This satisfies the inequality, hence this is the ordered pair.
