What is the slope of the line on the graph?
THANKS TO WHOEVER HELPS
Answer:
m = -2
Step-by-step explanation:
The points I will be using are (-3, 6) and (0,0).
To find the slope, you sub these points into the slope formula - rise over run.
Answer:
The slope is -2
Step-by-step explanation:
to get from (0,0) to (-3,6) you rise 6 and go left 3. Then 6÷-3= -2.
2x+7=x+3 solve for x
Answer:
x = -4
Step-by-step explanation:
Rearrange equation so that like terms are on one side and the numbers are on the other.
2x - x = 3 - 7
x = -4
Answer:
x=-10
Step-by-step explanation:
2x-x+7=x-x-3
x+7-7=-3=7
x=-10
(-49) - (-66)
Pls give relevant ans
Answer:
Step-by-step explanation: -49 -(-66)
= -49 + 66 ( here (-) and (-) is multiplied, therefore the final answer is +)
= 17 ( here when - and+ sign comes subtract them as we do normally, then mark the final answer with the greater number's sign, here the greater number is 66, so in the final answer we mark +17 or 17)

What is the missing term in the factorization?
12x^2 - 75 = 3( 2x+__ )( 2x - 5 )
Enter your answer in the box.
the missing term is 5
Step-by-step explanation:Hi there !
12x² - 75 =
= 3(4x² - 25)
use formula a² - b² = (a - b)(a + b)
= 3(2x - 5)(2x + 5)
= 3(2x + 5)(2x - 5)
the missing term is 5
Good luck !

You get a new job that pays a base salary of $45,000 per year and you earn a commission of $250 per unit sold. How many units would you need to sell to make $90,000 in a year.
Answer:
180
Step-by-step explanation:
subtract 45,000 (the money you already get) from 90,000 and you get 45,000. next divide 45,000 by 250 and get 180 (the amount of units you need to sell in order to make 90k total)
Please help me.
In a group of 45 students at a school, all students must study at least one science. Physics is compulsory, but students may also opt to study chemistry or biology or both. 9 students take all three sciences. 24 take both physics and biology (with or without chemistry). 12 students take only physics. How many are studying chemistry and physics but not biology?
Answer:
9 students
Step-by-step explanation:
Let x be the number of students taking only Physics and Chemistry
Number of students :
All 3 sciences = 9
Only physics = 12
Both Physics and Biology( without Chem ) = 24 -9 = 15
15+ 9 + 12+x = 45 , since Physics is compulsory
36 + x = 45
x = 45 - 36
x = 9
Hope it helps :)

5/3x+6=2/9x
Please answer x as a fraction
Answer:
x = -4 2/13
x = -4.15384615385
x = -54/13
(they are all the same, just in different formats)
Step-by-step explanation:
(5/3x) + 6 = (2/9)x
first, make all "x"s have a common denominator
(5/3) = (15/9)
so
(5/3)x = (15/9)x
(15/9)x + 6 = (2/9)x
solve using inverse operations
(15/9)x + 6 = (2/9)x
-(2/9)x -(2/9)x
(13/9)x + 6 = 0
-6 -6
(13/9)x = -6
to get rid of the fraction, multiply the entire equation by the denominator
(13/9)x = -6
*9 *9
13x = -54
/13 /13
x = -4 2/13
x = -4.15384615385
x = -54/13
(they are all the same, just in different formats)

Answer:

Step-by-step explanation:
We have the summation:
[tex]\displaystyle{\sum_{i=1}^{9} 2i-6[/tex]
Essentially, we want to find the sum of (2i-6) from i=1 to i=9.
First, using summation properties, we can split this to:
[tex]=\displaystyle{\sum_{i=1}^{9} 2i+\displaystyle{\sum_{i=1}^{9} -6[/tex]
On the right, it will simply be -6 evaluated 9 times. We can also move the constant out from the left:
[tex]=\displaystyle{2\sum_{i=1}^{9} i+9(-6)[/tex]
For the summation on the left, this will simply be the sum (1+2+3+...+9). This yields 45. Therefore:
[tex]=2(45)+9(-6)[/tex]
Evaluate:
[tex]=90-54=36[/tex]
So, our final answer is 36.

Write an equation to represent the total weight, p, of a full animal watering pail, if the pail weighs 12 pounds and the water weighs 8.3 pounds per gallon,g.
Answer:
12+8.3(g)=p
Step-by-step explanation:
#of gal of water x 8.3 per gal. number of gallons of water is not given so it is represented by g
+ weight of pail which is given, 12
= p , weight of full pail

A family car is being tested for fuel efficiency. It drives non-stop for 100 miles and uses 3.2 gallons of gasoline. Which of the following is the rates of distance traveled to fuel used?
Answer:
31.25miles per gallon
Step-by-step explanation:
Distance traveled = 100miles
Quantity of gasoline used = 3.2gallons
Unknown:
Rates of distance traveled to fuel used = ?
Solution:
The rates of distance traveled to fuel used is given as;
Rates = [tex]\frac{distance traveled}{fuel used }[/tex]
Input the parameters and solve;
Rates = [tex]\frac{100}{3.2}[/tex] = 31.25miles per gallon

Show that 3 · 4n + 51 is divisible by 3 and 9 for all positive integers n.
Answer:
4^1 + 17 = 21 , which is divisible by 3. 4^k + 17 and 3 * 4^k are both divisible by 3, so 4^k + 17 + 3 * 4^k is divisible by 3 as well. 3 * (4^n + 17) would be divisible by 9

The spinner below has three regions: $5, $0, and $10. To play the game, you spin one time and then you win the amount in the region that the spinner lands on. a.) What is the expected value for the game? b) If you have to pay $10 to play, is it a fair game? *
a) $5.00 b) no
a) $4.79 b) yes
a) - $ 8.75 b) no
a) $ 3.00 b) yes
Answer:
$5.00 ; no
Step-by-step explanation:
Given that:
135 / 360 = 0.375
90 / 360 = 0.25
135/ 360 = 0.375
X ___ 5 _____10 _____ 0
P(x): _0.25___0.375___0.375
Expected value :
ΣX*p(X) :
5(0.25) + 10(0.375) + 0(0.375)
1.25 + 3.75 + 0
= $5
b) If you have to pay $10 to play, is it a fair game?
For the game to be fair :
Amount paid = Expected winning
$10 ≠ $5
Since, amount paid is greater than expected winning, then the game is not fair
