Answer:
55 - 56i² + 94i
Step-by-step explanation:
11(5 + 6i) - 7i(8i - 4)
=> 55 + 66i - 56i² + 28i
=> 55 - 56i² + 94i
Therefore, 55 - 56i² + 94i is our simplified form.
Answer:
11(5+6i)−7(−4+8i)
11(5+6)−7(−4+8)
11(5+6)−(−28−56)
11(5+6)−(−56−28)
11(5+6)+56+28
55+66+56+28
(55+56)+(66+28)
111+94

Kim's age is twice that of her sister. When you add Kim's age to her sister's age, you get 30. How old is each sister?
(a) Write an equation that represents the situation. Explain any variable used.
(b) Solve the equation from Part (a). Show your work. State your solution as a complete sentence.
Answer:
Kim's age is twice of that of her sister. We'll let k2 = Kim and k = Kim's sister.
So, k2. When you add Kim's age to her sister age you get 30.
Because Kim is twice the age of her sister k2. And because it said 'add' then we put a + sign. k2 + s = 30. Now let's solve it.
k2 + k = 30 < Given
3k = 30 < Combine like terms
k = 10 < Divide both sides by 3
We know Kim's sister is 10 y/o but what about Kim herself? Earlier we assigned Kim to k2. Substitute 10 for k and you get 10(2) = 20
Kim's sister is 10 y/o and Kim is 20 y/o

PLEASE SOMEONE ANSWER THIS EQUATION FOR ME I NEED HELP ON THIS!!!!worth 20 points i will mark you brainliest
Answer:
2/3
Step-by-step explanation:
The slope of the line can be calculated by dividing the vertical distance (rise) by the horizontal distance (run) between the two points.
The first point has coordinates (-1,0), and the second point has coordinates (2,2).
The rise is 2-0=2, and the run is 2-(-1)=3. Therefore, the slope is 2/3.

Shayla decides to have a bbq for her birthday and purchased sodas and juice pouches. She paid $6 for each soda and the price of each juice pouch was 50% of each soda. She paid no more than $70.
Write an inequality that represents all possible combinations of x, the number of sodas, and y, the number of juice pouches purchased.
Answer:
Juice is 3 dollars
Step-by-step explanation:
If soda is 6 dollars then juice is 3 dollars. So dividing 70 we get 35$, she could get around 6 sodas and 12 jucies
Which equation represents a line which is perpendicular to the line
6
x
+
7
y
=
−
42
6x+7y=−42?
Answer:
Mark me as brainlist
Step-by-step explanation:
the equation is : y = ax+b
the slope is a : a×(2/7) = -1......( perpendicular to a line with a slope of 2/7) because : 2x-7y =-42...y=(2/7)x+6 )
a = -7/2 y=(-7/2)x+b
the line that passes through (6, -3) :- 3 = (-7/2)(6)+b
b =18
the equation is : y = (-7/2)x+18
