In the attached image you can find both quantities in a line 4 being less than 10. To have the absolute value equation we note that 7 is equidistant 3 units from 4 and 10 or another way to figure this out is 4+10/2=7 therefore the equation can be written as |d-7|=3
Answer:
See below
Step-by-step explanation:
<u>1. Solve for y</u>
- x = 0
- z = 5x + 3 ⇒ z = 5*0 + 3 = 3
- 4y + 6z = 26 ⇒ 4y + 6*3 = 26 ⇒ 4y = 26 - 18 ⇒ 4y = 8 ⇒ y = 2
- y = 2
- Option B
<u>2. Solve for x</u>
- -7x - y = 6 ⇒ y = -7x - 6
- x - 3y = 18 ⇒ x - 3(-7x - 6) = 18 ⇒ x + 21x + 18 = 18 ⇒ 22x = 0⇒ x = 0
- x = 0
- Option C
<u>3. Solve for x</u>
- y = -4
- z = 3x - 12
- 3x + 3y = -6 ⇒ 3x + 3(-4) = -6 ⇒ 3x = 12 - 6 ⇒ 3x = 6⇒ x = 2
- x = 2
- Option B
<u>4.....................</u>
- 0 = 1
- The equation is false so it means no solution
<u>5...................... </u>
- 0 = 0
- The equation is true so it means infinitely many solutions
Answer:
-52 / 5
Step-by-step explanation:
3 9/10 * -8 / 3 = 39 / 10 * -8 / 3 = -52 / 5
