-2x^2+8x-9+4x+7x^2+2
Answer:
Add like terms
Step-by-step explanation:
You want to combine the squared, the variables, and the constants.
Combine -2x^2 and 7x^2 to get 5x^2
Then combine 8x and 4x which is 12x
Then combine -9 and +2 which is -7.
You should get 5x^2 + 12x - 7.
Keep in mind you can only combine like terms that are in the same equals barrier
For example: You can combine 8x + 3 + 2x = 0
but not 8x +3 = 2x +0 because they are on different sides of the equal sign.

Predict how many times Max will choose a rectangular cracker if he carries out this process 200 times
Answer:
70 times.
Step-by-step explanation:
The following data were obtained from the question:
SHAPE >>>>>>>>>>>>> FREQUENCY
Oval >>>>>>>>>>>>>>> 18
Rectangle >>>>>>>>>> 14
Star >>>>>>>>>>>>>>> 8
TOTAL >>>>>>>>>>>>> 40
next, we shall determine the probability of chosing a rectangular cracker. This is illustrated below:
Event of Rectangle (nR) = 14
Sample space (S) = 40
Probability of chosing rectangle, P(R) =?
P(R) = nR/nS
P(R) = 14/40
P(R) = 7/20
Therefore, the probability of chosing a rectangular cracker is 7/20.
Thus, if the process were carried out 200 times, the probability of chosing a rectangular cracker will be:
= P(R) × 200
P(R) = 7/20
= 7/20 × 200
= 70
Therefore, max will chose a rectangular cracker 70 times.
Savannah's balance in her checking account was –$638.57. She deposited two checks, each in the amount of $298.40. What is Savannah’s new checking account balance after the deposits?
Answer:
$-41.77
Step-by-step explanation:
$298.40 multiplied by 2 is $596.8, since Savannah added 2 deposits.
Now we add that to the current balance, -$638.57, to get an answer of $-41.77
Answer:
-41.77
Step-by-step explanation:
Multiply $298.40 by 2 OR add $298.40 + $298.40
either gives you $596.80
Savannah deposited $596.80
You add that to -$638.57

(4k² + 8k +2) - (2k + 3)
а. 4k² + 6k + 5
b. 4k²+ 6k - 1
с. 4k²+ 10k +5
d. 4k²+ 6k + 1
Answer:
Step-by-step explanation:
4k^2 + 8k + 2 - 2k - 3
4k^2 + 6k - 1
answer is B
Answer:
[B] 4k²+ 6k - 1
Explanation:
(4k² + 8k + 2) - (2k + 3)
Remove Parenthesis
4k² + 8k + 2 - 2k + 3
-2k + 3: -2k - 3
= 4k² + 8k + 2 - 2k - 3
Simplify
4k² + 8k + 2 - 2k - 3: 4k²+ 6k - 1
= 4k²+ 6k - 1

Answer:
60 & 55
Step-by-step explanation:
1. the sum of the angles 1; 2 and 3 is 180°, then
m∠1=m∠2=m∠3; ⇒m∠3=60°;
2. m∠3=m∠r; ⇒ m∠r=60°;
3. m∠α= 180-(m∠r+65°)°; ⇒ m∠α=55°
all the details are in the picture.

What is -5(-3r-3)=75
Answer:
r = 4
Step-by-step explanation:
-5(-3r - 3) = 75
Divide both sides by -5.
-3r - 3 = -15
Add 3 to both sides.
-3r = -12
Divide both sides by -3.
r = 4
I need the answer to the image
Answer:
∠B = 156°
Step-by-step explanation:
A line intersects two parallel lines this means that their opposite angles are transversals specifically the angles, A and B. And transversal angles are congruent so I can make this claim below:
[tex]∠A = ∠B \\ 8x +78 = 2x +144[/tex]
Solving for x:
[tex]8x +78 = 2x +144 \\ 8x -2x +78 = 2x -2x +144 \\ 6x +78 -78 = 144 -78 \\ 6x = 66 \\ \frac{6x}{6} = \frac{66}{6} \\ x = 11[/tex]
Solving Angle B if x = 11.
[tex]∠B = 2x +144 \\ ∠B = 2(11) +144 \\ ∠B = 22 +144 \\ ∠B = 166[/tex]

f(x) = 3x + 10
g(x) = x - 2
Find f(g(0))
Answer:
4
Step-by-step explanation:
f(g(x)) = 3(x-2) + 10
f(g(0)) = 3x - 6 + 10
f(g(0)) = 3(0) - 6 + 10
f(g(0)) = 0 - 6 + 10
f(g(0)) = 4
If g(x) = 3x^2+2x-1. Find g(-1).
Step-by-step explanation:
g(x) = 3x² + 2x - 1
g(-1) = 3(-1)² + 2(-1) - 1
= 3(1) -2 -1
= 3 - 3
= 0
