What is the sum of 12 – 5i and –3 + 4i?
A. –16 + 63i
B. 9 – i
C. 9 – 9i
D. 15 – 9i
Answer:
B. 9 - i
Step-by-step explanation:
Combine the real and imaginary parts in numbers 12 - 5i and -3 + 4i
(12 + 5i) + (-3 + 4i)
12 - 3 + (-5 + 4)i
Add 12 to -3. Add -5 to 4.
9 + (-i)
9 - i

Two complementary angles have measures of `s` and `t`. If `t` is 9 less than twice `s`, what are the measures of each angle?
The value of s and t.
with work explaining.
Answer:
s measures 33° and t measures 57°.
Step-by-step explanation:
Since the two angles s and t are complementary, this implies that:
[tex]m\angle s+m\angle t=90[/tex]
We are given that t is 9 less than twice s. Hence:
[tex]m\angle t=2m\angle s-9[/tex]
We can substitute this into the first equation:
[tex]m\angle s+(2m\angle s-9)=90[/tex]
Solve for s. Combine like terms:
[tex]3m\angle s-9=90[/tex]
Adding 9 to both sides yields:
[tex]3m\angle s=99[/tex]
And dividing both sides by 3 gives us that:
[tex]m\angle s=33^\circ[/tex]
Returning to our second equation, we have:
[tex]m\angle t=2m\angle s-9[/tex]
So:
[tex]m\angle t=2(33)-9=66-9=57^\circ[/tex]
So, s measures 33° and t measures 57°.
Answer:
Two complementary angles have measures of `s` and `t`.
Hence, s+t=90°
`t` is 9 less than twice `s`, t=2s-9
According to the above problem,
→s+t=90
→s+2s-9=90
→3s=99
→s=99/3
→s=33
Therefore, the value of s=33°and t=2(33)-9 = 66-9 = 57°.What is the perimeter (please explain your answer)
Answer:
Answer: B. 38 mm
Step-by-step explanation:
The Perimeter of a Shape
The perimeter of a given shape is the sum of all exterior lengths surrounding the shape.
The figure shows a shape where all the external measures are given except the leftmost side.
This length is the sum of 3 mm + 10 mm = 13 mm.
Now calculate the perimeter:
P = 4 mm + 3 mm + 10 mm + 8 mm + 13 mm = 38 mm
Answer: B. 38 mm

There are 178 more bikers than hikers if there are 676 people in the park total how many people are hikers?
Answer:
The total number of hikers are 427
Step-by-step explanation:
Let:
The number of bikers = x
The number of hikers = y
There are 178 more bikers than hikers
y = x + 178
if there are 676 people in the park total how many people are hikers?
Hence:
x + y = 676
we substitute x + 178 for y
x + x + 178 = 676
2x + 178 = 676
2x = 676 - 178
2x = 498
x = 498/2
x = 249
y =x + 178
y = 249 + 178
y = 427
Therefore:
The number of bikers = x = 249
The number of hikers = y = 427
The total number of hikers are 427

DONE
What do the equations have in common and how are they different
Answer:
Slope -intercept for of equation 1: [tex]y=-2x+5[/tex]
Slope -intercept for of equation 2: [tex]y=-2x+3[/tex]
Looking at slope-intercept form of both equations, we have slope m = -2
Both have same slopes so, the lines are parallel.
Step-by-step explanation:
We need to write equations in slope-intercept form.
The general formula of slope-intercept form is: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
The first equation is:
[tex]2x+y=5[/tex]
Slope-intercept form:
[tex]y=-2x+5[/tex]
The second equation is: [tex]3y=9-6x[/tex]
Rearranging: [tex]3y=-6x+9[/tex]
Slope-intercept form:
[tex]y=\frac{-6}{3} x +\frac{9}{3}\\y=-2x+3[/tex]
Slope -intercept for of equation 1: [tex]y=-2x+5[/tex]
Slope -intercept for of equation 2: [tex]y=-2x+3[/tex]
Looking at slope-intercept form of both equations, we have slope m = -2
Both have same slopes so, the lines are parallel.
They have different y-intercepts.

Answer:
The 3 possible values of x are;
6, 4 and 2
Step-by-step explanation:
If the triangle is isosceles, then two of the sides must be equal
So we equate the sides, 2 at a time to get the different values of x
3x + 4 = 2x + 10
3x-2x = 10-4
x = 6
3x + 4 = x + 12
3x-x = 12-4
2x = 8
x = 8/2 = 4
2x + 10 = x + 12
2x - x = 12-10
x = 2

Step-by-step explanation:
-10 - 6x > 26
+10 +10
-6x > 36
-6 -6
When you multiple/divide by a negative you have to flip the sign
x < -6
Answer:
c
Step-by-step explanation:
Given
- 10 - 6x > 26 ( add 10 to both sides )
- 6x > 36
Divide both sides by - 6, reversing the symbol as a result of dividing by a negative quantity.
x < - 6 → c

. Mr. and Mrs. Collins took their son and his 7 friends to the movies in Philadelphia. Each of the 8 tickets cost the same amount of money. They spent $22.00 for parking their van. Mr. and Mrs. Collins are charged a total of $118.00 for parking and tickets. Mr. and Mrs. Collins do not watch the movie. What is the price of each ticket to the movies
Answer:
$12
Step-by-step explanation:
amount spent for 8 movie tickets is equal to 118 - 22 = 96
divide 96 by 8 to get per movie ticket cost of $12
how do you solve 5/2 b - 2 3/4 = 7 1/4
solve the system of equations
Answer:
x= -8
y=7
Step-by-step explanation:
make it so the x's cancel out
to do this multiply the bottom equation by 2
2x+3y=5
2x+4y=12
subtract to cancel out the x
-y=-7
y=7
now substitute y into one of the equations(I'm going to do x+2y=6)
x+2(7)=6
x+14=6
x=-8
