6x-4y=-14 -3x-3y=12with the elimination method

1 answer:

8 0

6x-4y=-14
2(-3x-3y=12)

6x-4y=-14
-6x-6y=24

-10y=10
Divide both sides by 10
-1y=1 divide by -1
y=-1

6x-4(-1)=-14
6x+4=-14
-4 -4
6x=-18
Divide both sides by 6
x=-3

Answer:

(2,-7)

Step-by-step explanation:

Plug in the numbers to test and see if it gives you -17 and -8.

Option 1. 2(-4)+3(2)

= -8+6 = -2. Not it.

Option 2. 2(2)+3(-7)

4 - 21 = -17 Works. Try the second equation to make sure.

3(2)+2(-7)

6-14 = -8. Works.

(2,-7) is the answer.

Write a formula for g(x) in terms of x.

liberstina [14]

The formula of g(x) is g(x) = -0.8x - 1.6

<h3>How to determine the formula of g(x)?</h3>

The equation is given as:

-4x - 6 = 5y + 2

Subtract 2 from both sides

5y = -4x - 8

Divide through by 5

y = -0.8x - 1.6

Express as a function

g(x) = -0.8x - 1.6

Hence, the formula of g(x) is g(x) = -0.8x - 1.6

All the fraction that are greater than 1\2

never [62]

Hi There!

Change all the fractions to decimal you do that by dividing numerator by the denominator. Remember $\frac{1}{2}$ as a decimal is 0.5

A= $\frac{3}{7}$ = 0.43

B= $\frac{5}{9}$ = 0.60

C= $\frac{8}{10}$ = 0.8

D= $\frac{5}{12}$ = 0.42

E= $\frac{3}{5}$ = 0.6

Based, on the data above B,C,E are greater than $\frac{1}{2}$ because they all have decimals greater than 0.5, B= 0.6, C= 0.8, E=0.6

So, $\frac{5}{9} ,\frac{8}{10} ,\frac{3}{5}$ are all greater than $\frac{1}{2}$

Hope This Helps :)
