X= 2y-5
4x+3y=-9

Answers

Step-by-step explanation:

x=2y-5 - equation 1

4x+3y=-9 -equation 2

Replace equation 1 in equation 2

4(2y-5)+3y=-9

8y-20+3y=-9

11y=-9+20

11y=11

y=11/11

y=1

If y=1, therefore x=2(1)-5=-3

x=-3,y=1

Jasmin can walk 1/4 mile every 1/5 hour. At this rate, how far can Jasmin
walk in one hour?

Answers

Answer:

hope this helps :)

Step-by-step explanation:

Since we know how far she can walk in 1/5 (one fifth) of an hour, if we multiply this distance by 5, we will find out how far she can walking in 5/5 (five fifths) of an hour, or to be clear: in one hour.

So, 5 x 1/4 miles = 5/4 or 1.25 miles per hour

What is the solution to the inequality 7<=-3x-4

Answers

Answer:

The nearest option is -3 (negative 3)

So, Option B is correct.

Step-by-step explanation:

We need to solve the inequality [tex]7 \leq -3x-4[/tex]

Solving:

Step 1: Switching sides of inequality and reversing the inequality

[tex]-3x-4\geq 7[/tex]

Step 2: Adding 4 on both sides

[tex]-3x-4+4\geq 7+4\\-3x\geq 11[/tex]

Step 3: Dividing both sides by -3 and reversing the inequality

[tex]\frac{-3x}{-3}\leq \frac{11}{-3} \\x\leq -3.6\\[/tex]

The nearest option is -3 (negative 3)

So, Option B is correct.
