Which shows the correct substitution of the values ab and c from the equation 0 = - 3x ^ 2 - 2x + 6 into the quadrati formula?
The answer would look something like this:
[tex]\frac{2+-\sqrt{2^{2}-4(-3)(6) }}{2(-3)}[/tex]
There could also have a simplified version.
I hope this helps.
What is the slope of the line of best-fit in the scatterplot below?
Answer:
Option C
Step-by-step explanation:
Using the slope formula and the points in the picture: (3,12) (6,19)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{19-12}{6-3}=\frac{7}{3}[/tex]
The slope of the line is 7/3.
Option C should be the correct answer.
Answer:
Your correct answer is option C. 7/3

Need the answer to this one please
The answer is A.
I used a graphing calculator.
Answer:
the first one
Step-by-step explanation:
slope: use rise-over-run theorem. the slope of the graph rises -2 for every 1 unit over, so slope is -2x
intercept: the line crosses the y-axis at y=3, hence +3
put it together: y=-2x+3

-3.6 - 1.9t + 1.2 + 5.1t
Answer:
3.2t-2.4
Step-by-step explanation:
-3.6 - 1.9t + 1.2 + 5.1t
Combine like terms
-3.6+ 1.2 - 1.9t +5.1t
-2.4 + 3.2t
Answer: 3.2t-2.4
Step-by-step explanation:
First thing you need to do is do -1.9t+5.1t= 3.2t. Then you do -3.6+1.2= -1.2.
Then put all this together and you get 3.2t-1.2. (do not do 3.2t+-1.2 this incorrect because we left the subtracting sign
Solve the simultaneous equations
2x - 3y = 18
5x + 9y = -10
Answer:
2x - 3y = 18 (1)
5x + 9y = -10 (2)
<=>
Multiply both sides of (1) by 5, and multiply both sides of (2) by 2, then:
10x - 15y = 90
10x + 18y = -20
Subtract (2) to (1):
=> 33y = -110 => y = -110/33
Substitute y back into (1):
=> 2*x - 3*(-110/33) = 18
=> 2*x + 10 = 18
=> 2*x = 8
=> x = 4
=> Solution: x = 4, y = -110/33
Hope this helps!

On a coordinate plane, trapezoid A B C D has points (negative 3, negative 2), (negative 1, 2), (3, 2), and (5, negative 2). Trapezoid ABCD is graphed in a coordinate plane. What is the area of the trapezoid? 16 square units 24 square units 32 square units 48 square units
Answer:
Correct option: second one -> 24 square units
Step-by-step explanation:
First we need to find the length of each side of the trapezoid, and we do that finding the distance between points:
AB = sqrt( (-1 - (-3))^2 + (2 - (-2))^2) = 4.4721
BC = sqrt( (3 - (-1))^2 + (2 - 2)^2) = 4
CD = sqrt( (5 - 3)^2 + (-2 - 2)^2) = 4.4721
DA = sqrt( (-3 - 5)^2 + (-2 - (-2))^2) = 8
The points B and C have the same y-coordinate, and the points D and A also have the same y-coordinate, so they are the bases of the trapezoid.
The height of the trapezoid is the difference in y-coordinate of points B and A:
height = 2 - (-2) = 4
So the area of the trapezoid is:
Area = (BC + DA) * 4 / 2 = (4 + 8) * 2 = 24 square units
Correct option: second one
Answer:
Its B

Devon started the week with $50 in his checking account. On Monday he took $20 out of the
account. On Tuesday, the balance of Devon's account changed to $0. Which value best
represents the change to his account balance on Tuesday?
Answer:
see below
Step-by-step explanation:
Starting with 50
Took out 20
50-20 = 30
Then the balance was 0
We need to subtract 30 to get to get to 0
30-30 = 0
Taking out 30
Withdrawing 30
Spending 30
All are ways of indicating taking out 30 dollars
Answer:
On Tuesday, Devon took 30 dollars out of his checking account.
Step-by-step explanation:
Starting with: $50 - Ending with $0
Monday: took out $20 or in other words -20 50-20=30
Tuesday: undetermined, but since that was his last day, it would correspond with $0 so, he must've took out $30 and then ended up with none in the end.
30-30=0
So, he took 30 dollars out on tuesday.
There were 144 people in attendance at the school football game last Friday. This week there were 346 people in attendance at the school football game.What is the percent of change from last week to this week?Round your answer to the nearest whole number
Answer: 140%
Step-by-step explanation:
STEP 1: FIND THE CHANGE IN # OF PEOPLE:
initial # of people: 144
final # of people: 346
change in # of people = (final - initial)
change in # of people = (346 - 144)
change in # of people = 202
STEP 2: FIND THE % CHANGE
202/144 = x/100
(100)(202/144) = x
100(1.4) = x
140% = x
Answer:
140 %
Step-by-step explanation:
(346-144)/144 * 100
(202/144) * 100

Answer:
g(n) = [tex]\frac{11+5n}{3}[/tex]
Step-by-step explanation:
Given
3m - 5n = 11
Rearrange making m the subject
Add 5n to both sides
3m = 11 + 5n ( divide both sides by 3 )
m = [tex]\frac{11+5n}{3}[/tex] , thus
m = g(n) = [tex]\frac{11+5n}{3}[/tex]

Answer:
x > 0
Step-by-step explanation:
Division by zero is not defined. Therefore, x must be greater than zero. Also: The square root function is defined only for x greater than zero or equal to zero. Together these restrictions tell us that the domain is (0, infinity ).
If sin a-b =1/2 and cos a+b =1/2 Find a and b
Answer:
[tex]a = \frac{1}{2} [/tex]
[tex]b = 0[/tex]
Step-by-step explanation:
[tex]a - b = \frac{1}{2} \\ a + b = \frac{1}{2} \\ \\ a - b + a + b = \frac{1}{2} + \frac{1}{2} \\ a + a = \frac{2}{2} \\ 2a = 1 \\ \frac{2a}{2} = \frac{1}{2} \\ a = \frac{1}{2} [/tex]
[tex]a + b = \frac{1}{2} \\ \frac{1}{2} + b = \frac{1}{2} \\ b = \frac{1}{2} - \frac{1}{2} \\ b = 0[/tex]

find the value of JW given that JW=6x+2 and JB=10x+1
The value of JW is 14 units.
What is a triangle?A triangle is a polygon with 3 sides. The area of a triangle with base b and height h is given by A = (1/2)bh.
Given that, JB is the median of the triangle and JW = 6x + 2 and JB = 10x + 1.
The distance between the centroid and a vertex of a triangle is 2/3 of the length of the median, therefore, it follows:
JW = (2/3)JB
Substitute the values:
6x + 2 = (2/3)(10x + 1)
18x + 6 = 20x + 2
2x = 4
x = 2
Substitute x = 2 into the expression for JW:
JW = 6(2) + 2
JW = 14
Hence, the value of JW is 14 units.
