Hey there! I'm happy to help!
Here is our equation
3x - 4 (2x - 5) = 15
First, we will sue the distributive property to remove the parentheses. The term outside the parentheses is -4, so that is what we multiply the insides by.
3x-8x+20=15
We combine our like terms (our x-values).
-5x+20=15
We subtract 20 from both sides.
-5x=-5
We divide both sides by -5.
x=1
Have a wonderful day and keep on learning! :D
Answer:
If B is between A and C, AB = x, BC = 2x + 2, and AC = 14, find the value of x. Then find AB and BC.
Step-by-step explanation:
AB=x
BC = 2x + 2BC=2x+2
AC =14AC=14
Required
Determine x, AB and BC.
Since B is between A and C;
AB + BC = ACAB+BC=AC
Substitute x for AB; 2x + 2 for BC and 14 for AC
x + 2x + 2 = 14x+2x+2=14
3x + 2 = 143x+2=14
Collect Like Terms
3x = 14 - 23x=14−2
3x = 123x=12 '
x = \frac{12}{3}x=
3
12
x = 4x=4
Substitute 4 for x in
AB = xAB=x
BC = 2x + 2BC=2x+2
AB = 4AB=4
BC = 2(4) + 2BC=2(4)+2
BC = 8 + 2BC=8+2
BC = 10BC=10
Answer:
-5/8
Step-by-step explanation:
Step 1: Find the slope of line d. As we move from point (5, 2) to point (10, 10), x increases by 5 and y increases by 8. Thus, the slope of line d is
m = rise / run = 8/5.
Step 2: Find the negative reciprocal of this m = 8/5. Doing so will give us the slope of line e or of any other line perpendicular to line d:
Slope of line e: -(5/8) = -5/8
Answer:
Subtract: 5 - 9i = 5-9i
Add: the result of step No. 1 + (-4) = (5-9i) + (-4) = (5-4) + (-9i) = 1-9i
Add: the result of step No. 2 + 7i = (1-9i) + 7i = 1 + (-9+7)i = 1-2i
Subtract: 1 - 2i = 1-2i
Subtract: the result of step No. 1 - 4 = (1-2i) - 4 = (1-4) + (-2i) = -3-2i
Add: the result of step No. 2 + 7i = (-3-2i) + 7i = -3 + (-2+7)i = -3+5i
