If — 2x + 3 = 13, then 2x
?
Hi!
Your answer should be: -2x= 10
Reason being: -2+3= 0
So this must mean: x=10
Because 10+3=13
Hope this helps!
Yours truly,
~~~PicklePoppers~~~Answer:

h(x) = 10x - x2 + 4
h(2) =
Answer:
h(2) = 20
Step-by-step explanation:
h(x) = 10x - x^2 + 4
Let x = 2
h(2) = 10*2 - 2^2 + 4
=20 -4+4
=20
Seven students have been entered into the prize drawing for perfect attendance. The first name drawn recieves a $50 giftcard. The second name drawn recieves a $25 giftcard. The third name drawn recieves a $10 giftcard. How many ways can these rewards be given out? * bila.
Answer:
21
Step-by-step explanation:
there are 7 students and 3 prizes so all you needed to do was multiply 3 by 7 or 7 by 3.
Answer:
35 different ways!
Step-by-step explanation:
7! / 3! * (4!)
If you know combinations and permutations, then the above formula will make sense.
Since this question is asking for all possible combinations, it's this formula if you don't know it:
n! / r! (n - r)!
n is the total number of things, which in this case are people. So, we get 7 and r is the set amount of the things used at a time which is 3... because out of 7 people only 3 can win gift cards.
Hope this helps!

Answer:
8
Step-by-step explanation:
simple, divide 24/3 and you get your answer.
why?
because when you divide 3(game) by 24(score) you get how much score you get per 1 game.
same if you divide for 32/4 and 5/40, you get the same answer.
find the median of the given data if the mean is 4.5.5,7,7,8,x,5,4,3
Find the median of the given data. If the mean is 4.5...
5, 7, 7, 8,x,5,4,3 = x, 3, 4, 5, 5, 7, 7, 8
The median is 5. For the second part... The question is incomplete... “If the mean is 4.5...” Also, I have no idea if x should have been added or not. Even if it was, it doesn’t change the answer.

Step-by-step explanation:
90
-------------------
10 + (3^2 - 4)
first we look at the parenthesis. take 3 to the second power, and it equals 9
90
------------------
10 + (9 - 4)
next, still in the parenthesis you subtract 4 from 9
90
--------------
10 + (5)
next add 10 plus 5
90
------- = 6
15
now divide 90 by 15 and you get your answer, 6

Answer:
x=1±i√5
Step-by-step explanation:
the quadratic equation is in the form :
y=ax²+bx+c
y= 2x²-4x+12
x=(-b±√b²-4ac)/2a
x=-(-4)±√-4²-4(2)(12)/2a
x=4±√16-96/4
x=4±√-80/4
since the number under the square root then √-80=4i√5 ( assuming possitive numbers)
x=(4±4i√5)/4
x=4(1±i√5)/4
x=1±i√5

Answer:
b) -12 , -8 , -4, 0
Step-by-step explanation:
-12 + 4(n - 1)
n means the term
place the values of 1, 2, 3 and 4
-12 + 4(1-1) = -12
-12 + 4(2-1) = -8
-12 + 4(3-1) = -4
-12 + 4(4-1) = 0
hence the answer is
b) -12 , -8 , -4, 0

8b-7 = 7b - 2
-12+5k=15-4k
Answer:
Step-by-step explanation:
8b - 7 = 7b - 2
Bringing like terms on one side
8b - 7b = - 2 + 7
B = 5
-12 + 5k = 15 - 4k
Bringing like terms on one side
5k + 4k = 15 + 12
9k = 27
k = 27/9 = 3

Hi there! :)
a) (ii) The two angles are vertical angles, so they are congruent.
b)(i) y = 71°
(ii) The two angles are alternate interior angles, so they are congruent.
c) z = 44°
(ii) m∠x = 65° because the two angles are vertical angles, so they are congruent.
b) (i)
∠y is an alternate interior angle, therefore:
m∠y = 71°
c) Use the sum of interior angles of a triangle to determine the measure of angle z:
180 = 65 + 71 + z
180 = 136 + z
180 - 136 = z
z = 44°.

20.0% Complete You work on a manufacturing line. Currently, the status board for the line says"-55" This means that your line still needs to produce 55 items to meet the day's goal. Q. If your line produces 30 items in the next hour, what number will be displayed on the status board? A. 25 B. 85 C. -25 D. -85
Answer:
C. -25
Step-by-step explanation:
Since the current number is -55, it depicts the number to achieve the target.
That is the current position states that we require 55 more units to produce.
If we produce 30 more units in an hour, we shall require 55 - 30 = 25 more units to produce, in order to achieve target.
Since target is decreased by 30, but yet not achieved completely it will still be a negative number.
Thus, the correct answer is
C. -25
This depicts that achieved volume of units is short by 25 units in order to achieve the target.
