Combine like terms - in this case, that would be the real and imaginary parts:
(8 - 2i) + (5 + 9i) = (8 + 5) + (-2i + 9i)
… = 13 + 7i
Then a = 13 and b = 7.

Which is an example of having infinitely many solutions? 1 Point 2x+8 = 2(x+8) 3x + 2(x - 2) + 6 = 5x + 2 x+7=7 X=0
Answers
Given:
The different equations in the options.
To find:
The equation which have infinitely many solutions.
Solution:
In option A,
[tex]2x+8=2(x+8)[/tex]
[tex]2x+8=2x+16[/tex]
[tex]8=16[/tex]
This statement is false for any real value of x. So, the given equation has no solution.
In option B,
[tex]3x+2(x-2)+6=5x+2[/tex]
[tex]3x+2x-4+6=5x+2[/tex]
[tex]5x+2=5x+2[/tex]
[tex]2=2[/tex]
This statement is true for all real value of x. So, the given equation has infinitely many solutions.
In option C,
[tex]x+7=7[/tex]
[tex]x=7-7[/tex]
[tex]x=0[/tex]
This equation has only one solution, i.e., x=0.
In option D,
[tex]x=0[/tex]
This equation has only one solution, i.e., x=0.
Only equation [tex]3x+2(x-2)+6=5x+2[/tex] has infinitely many solutions. Therefore, the correct option is B.
Which equation represents the line that has a slope of -2 and passes through the point (6,5)?
A. y= -2.6 - 17
B. Y = -23 - 16
c. y = -2x + 16
D. y = -2.c + 17
Pls don’t write random thing I really need helllppp
Answers
Answer:
y = - 2x + 17
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2, then
y = - 2x + c ← is the partial equation
To find c substitute (6, 5) into the partial equation
5 = - 12 + c ⇒ c = 5 + 12 = 17
y = - 2x + 17 ← equation of line

Answers
Given:
Each time Sally waters her tomato plants she uses 5 liters of water.
Sally waters her tomato plants 3 times a week.
To find:
How much water, in liters, does Sally use in a week?
Solution:
We have,
Water used in each time = 5 liters
Number of times Sally waters her tomato plants = 3 times
Now,
Water used in 1 time = 5 liters
Water used in 3 time = 3×5 liters
= 15 liters
Therefore, the Sally use 15 liters of water in a week.

Mrs. Hector wanted to bring giant souvenir snow globes, which weigh 1.5 kg each, back to the USA as presents for her students. Mrs. Hector's suitcase weighs 2.4 kg, but she wanted to fill it with as many snow globes as possible. Write and solve an inequality to determine the maximum number of snow globes that Mrs. Hector could have brought back in her suitcase.
Answers
Answer:
the maximum number of snow balls can bought back = 1.6
Step-by-step explanation:
Let
Mrs. Hector brings total number of giant snow globes = x
As given,
weight of 1 snow globe = 1.5 kg
So,
Weight of x snow globe = 1.5x
As given,
She have to take them in a suitcase of weight 2.4 kg
∴
For number of snow globes we have the equation,
1.5x = 2.4
⇒x = [tex]\frac{2.4}{1.5}[/tex] = 1.6
So, the maximum number of snow balls can bought back = 1.6
I have a D in math. May someone please help me get it up by helping me on this assignment? Thank you so much!! 25 points btw :))

The area of first area is (2t)^2*pi or whatever that variable is, I assume its t because its not clear.
The area to the second circle is t^2*pi
The area together is 80 which means
(4t^2+t^2)pi=80
5t^2pi=80
t^2pi=16
The radius of the smaller circle, t, will be 4/sqrt(pi) or 4sqrt(pi)/pi
So the larger circle has double the radius thus it will be
8/sqrt(pi) or 8sqrt(pi)/pi
This is the value, but if your teacher wants an approximate value just punch this into an calculator :) Hope it helps!

Answers

Answer:
35 feet square
Step-by-step explanation:
The greatest common factor of 70 and 525 is 35. The largest square plot can be 35 feet on a side.
70 = 2·35
525 = 15·35

I like to find the GCD (greatest common divisor) using Euclid's algorithm. We find the remainder when dividing the larger by the smaller. When that remainder is not zero, we replace the larger number with the remainder, and repeat. When the remainder is zero, the divisor is the GCD.
525/70 = 7 r 35
70/35 = 2 r 0 . . . . . 35 is the GCD

Answers
Answer:
C) Do the inverse or opposite operations
Step-by-step explanation:
Take for example the equation 4=2x. Because 2 is being multiplied by x, the only way for x to get by itself is to do the opposite operation; dividing both sides by 2 to get 2=x.

D. 9 + 4√5
Step-by-step explanation:
What we're essentially doing here is squaring 2 + √5. (2 + √5 and 2 + 1√5 are essentially the same)
(2 + √5)(2 + √5) (I didn't put the one on the conjugate for a reason; look above)
Step 1: Apply the distributive property by multiplying each term of 2 + √5 by 2 + √5
4 + 2√5 + 2√5 + (√5)²
Step 2: Combine 2√5 and 2√5 to get 4√5.
4 + 4√5 + (√5)²
Step 3: The square of √5 is 5.
4 + 4√5 + 5
Step 4: Add 4 and 5 to get 9.
9 + 4√5 is the final answer to this question.
