The value of x is 0.65
<u>Step-by-step explanation:</u>
This solution is given by solving the given problem using BODMAS rule.
This means that the steps to be followed to find the solution should be in the order of BODMAS rule.
B- Bracket, O- of, D- Division, M- Multiplication, A- Addition, S- Subtraction.
This rule states that the 1st operation must be done for Brackets.
⇒ -3.75+2(-4x+6.1)-3.25 = 0
⇒ -3.75 -8x + 12.2 -3.25 = 0
The addition operation should be performed next and then followed by subtraction.
⇒ -8x -7+ 12.2 = 0
<u>To find the value of x :</u>
Keeping the x term alone on one side and moving the constants on other side,
⇒ -8x = -12.2 + 7
⇒ -8x = -5.2
⇒ x = 5.2/8
⇒ x = 0.65
-2x - 8 > -12
-2x - 8 + 2x > -12 + 2x ...... add 2x to both sides
-8 > -12 + 2x
-8+12 > -12+2x+12 .... add 12 to both sides
4 > 2x
2x < 4 ..... flip both sides so that the x term is on the left side
2x/2 < 4/2 .... divide both sides by 2
x < 2
This describes the set of x values such that x is less than 2.
The largest integer that x can be is x = 1. The value of x cannot be 2 because we don't have an "or equal to" as part of the inequality sign.
Final Answer: 1
Answer: "C"
roots would make the function "0"
so just plug in the numbers...
with a + 12 you need minuses to cancel out...
B & C can not be the answer...
A is -i -3 + 4i - 12 which also is not 0
C is : 8i -12 -8i +12 WHICH DOES = 0
Step-by-step explanation:
Answer:
n=5 and it's output is -13
Step-by-step explanation:
By inspection, the inputs increase by +1 and the outputs decrease by 2
Thus ,n=4+1=5 and it's output is -11-2=-13
3x + 4y = 19
3x + 6y = 33
2y = 14
y = 7
3x + 28 = 19
3x = -9
x = -3
3x + 42 = 33
3x = -9
x = -3
