Answer:

the graph that goes through the points

(0,3), (-4,0)

Step-by-step explanation:

make y the subject

3x-4y=-12

4y=3x+12

y=(3x+12)/4

now when x=0

y=12/4=3

so coordinates (0,3)

now when y=0

0=(3x+12)/4

by multplying both sides by 4

0=3x+12

0=3 (x+4)

divide both sides by 3

0=x+4

x=-4

so coordinates (-4,0)

Identify all factors of the expression 〖4x〗^2+17x-15.

Basile [38]

The factors of given expression are: -5 and 3/4

Step-by-step explanation:

Given equation is:

$4x^2+17x-15$

Making pairs for the mid-term 17x by factoring the product of co-efficient of 4x^2 and 15

$4x^2+20x-3x-15$

$= 4x(x+5) - 3(x+5)$

$=(4x-3)(x+5)$

Now

$4x-3 = 0\\4x = 3\\x = \frac{3}{4}$

$x+5 = 0\\x = -5$

Hence,

The factors of given expression are: -5 and 3/4

6x + 2y > 48 solve for y

kozerog [31]

Answer:

y > 24 − 3x

Step-by-step explanation:

Step 1: First, you need to factor out the common term 2.

2 (3x + y) > 48

Step 2: Then, you divide both sides by 2.

$3x+y>\frac{42}{2}$

Step 3: Next, you have to simplify $\frac{42}{2}$ into 24.

3x + y > 24

Step 4: Lastly, subtract 3x from both sides and you're done!

y > 24 − 3x
