8-2i is their total score. You can't combine the imaginary numbers and real numbers.
Let's solve your equation step-by-step.
2x
/5 + 3 = x/10 - 1
Step 1: Simplify both sides of the equation.
2x
/5 + 3 = x/10 - 1
2/5x + 3 = 1/10x - 1
Step 2: Subtract 1/10x from both sides.
2/5x + 3 - 1/10x = 1/10x - 1 - 1/10x
3/10x + 3 = -1
Step 3: Subtract 3 from both sides.
3
/10x + 3 - 3 = -1 - 3
3/10x = -4
Step 4: Multiply both sides by 10/3.
(10/3) * (3/10x) = (10/3) * (-4)
x = -40/3
Answer:
4
Step-by-step explanation:
to solve | a | - | b | + | c | we need to plug in the given values
a = -8
b = -5
c = 1
the | | bars mean absolute value which is the exact value a number is away from 0 on a number line. an absolute value has to be positive, not a negative, as you cant be negative spaces away from something. plugging in the values into the equation we have:
| -8 | - | -5 | + | 1 |
the absolute value of -8 is 8, as -8 is 8 units away from 0 on a number line
like wise with -5, the absolute value of -5 is 5, as -5 is 5 units away from 0 on a number line
1 is the absolute value of 1 as its 1 unit away from 0 on a number line
the new expression looks like the following:
8 - 5 + 1
now we just add/subtract
8 -5 = 3
3 + 1 = 4
the solution to this expression is 4
Answer:
Step-by-step explanation:
1) Use the given coordinate points to find the slope
m=
m=
2) plug the slope into slope-intercept form
y=x+b
3) choose one point to use to plug into the equation to solve for b
4=(-2)+b
4) solve for b.
b=
5) substitute the value for b into equation from step 2
y=x+
