Answer:
2(x-3)
Step-by-step explanation:
2x² - 2x - 12= 2(x²-x+6)= 2(x²+2x- 3x+6)= 2(x-3)(x+2)
(2x² - 2x - 12)/(x+2)= 2(x-3)(x+2)/(x+2)= 2(x-3)Write the equation for a line that passes through the point (2,5) and a slope of m =10 in point slope form
Answer:
y=10x-15
Step-by-step explanation:
with the points given you know x=2 and y=5
make a new point called (x,y)
now use the formula (y-5)/(x-2)=10 (10 being the gradient)
y-5 = 10(x-2)
y-5=10x-20
add 5 to both sides
y-5+5=10x-20+5
y=10x-15
Since we're given a point and a slope, we can write
the equation of this line using the point-slope formula.
The point-slope formula is shown at the top of the image below.
The given point, (2,5), represents (x1,y1).
Now plug in the information to get the equation below.
Now you can distribute the 10.
Then add 5 to both sides.
You will end up with the equation y = 10x - 15 as your answer.
I need assistance :D, Instructions: Using the image, find the distance between the points given on the graph.
Answer:
Step-by-step explanation:
You have to use the distance formula to find that distance. The formula is:
[tex]d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
Let's call the first point x1, y1 (4, -1) and the second point x2, y2 (0, -2). Plugging into our formula then gives us this:
[tex]d=\sqrt{ (0-4)^2+(-2-(-1))^2}[/tex]
which simplifies to
[tex]d=\sqrt{(-4)^2+(-1)^2}[/tex] which is
[tex]d=\sqrt{17}[/tex] ≈ 4.123 units

Answer:
3.5
Step-by-step explanation:
LJ/sin 23° = 9/sin 89°
LJ/0.39 = 9/0,99
LJ = (9*0.39)/0.99 = 3.517
LJ ≈ 3.5
Answer:
3.5
Step-by-step explanation:
∠K is about 3 times less than ∠J
so opposite sides have roughly same ratio
Only the last option, 3.5 is close to the length 3 times less than 9
It costs $2.80 to make a sandwich at the local deli shop. To make a profit, the deli sells it at a price that is 170% of the cost. The sandwich sells for $___. (Make sure to enter the answer as a decimal number only. Do not enter special characters such as the dollar symbol.)
Answer:
$4.76
Step-by-step explanation:
It costs $2.80 to make a sandwich at the local deli shop and the deli sells it at a price that is 170% of the cost.
We have to find 170% of the cost of making each sandwich ($2.80):
170/100 * 2.80 = $4.76
The sandwich sells for $4.76

Answer:
A and B
Step-by-step explanation:
Mrs. Quotient asked her students to simplify each of the expressions below. Which of the numbered choices represents the expressions which simplified to the same result? A 126/2 B 23 × 3 C 3 × 21
When simplifying an algebraic expression, the following steps are needed to be taken.
Firstly, remove parenthesis by multiplying the constant with the term in the parenthesis or remove parenthesis using exponent rules for parenthesis in exponent form.
Secondly Combine terms by adding coefficients of terms with the same order and lastly sum all constant.
A) 126/2
Applying the division rule give:
126/2 = 63
B) 23 × 3
Applying multiplication rule gives:
23 × 3 = 69
C) 3 × 21
Applying multiplication rule gives:
3 × 21 = 63
Both the results of expression A and expression B are simplified to the same result

A bag contains 5 blue marbles, 6 red marbles, and 4 green marbles. You select one marble at random from the bag. What is P(blue)?
Answer:
P(blue) = 1/3 (Answer)
Step-by-step explanation:
Probability for any event A is given by
p(A) = no of times of happening of event A/ total no of occurrence of all the event given under the situation.
____________________________________
A bag contains 5 blue marbles, 6 red marbles, and 4 green marbles
So, total no of occurrence of all the event given under the situation
one can either pick blue , red or 4 green marbles
Total no. of occurrence of all the event = 5 + 6 + 4 = 15
Now , no of occurrence of selecting blue.
since there are 5 blue marbles, there is chance of selecting blue is 5.
no of occurrence of selecting blue = 5
Therefore,
P(blue) = no of occurrence of selecting blue /total no of occurrence of picking any color ball
P(blue) = 5/15 = 1/3 (Answer)
Parallelogram P Q S R is shown. The length of P Q is (2 x + 5) centimeters and the length of R S is (4 x + 1) centimeters. In parallelogram PQSR, what is PQ
Answer:
9 cm
Step-by-step explanation:
Since PQ and RS are opposite each other, then in a parallelogram, the lengths will be congruent.
Therefore 2x+5=4x+1
2x=4
x=2
If you plug x=2 into the the original equation, you get 9 cm.
The measure of PQ is 9 centimeters.
Important information:
In parallelogram [tex]PQSR, PQ=(2x+5),RS=(4x+1)[/tex]Parallelogram:The oppositie sides of a parallelogram are equal.
[tex]PQ=RS[/tex]
[tex]2x+5=4x+1[/tex]
[tex]5-1=4x-2x[/tex]
[tex]4=2x[/tex]
Divide both sides by 2.
[tex]2=x[/tex]
Now, find the measure of PQ.
[tex]PQ=2x+5[/tex]
[tex]PQ=2(2)+5[/tex]
[tex]PQ=4+5[/tex]
[tex]PQ=9[/tex]
Therefore, the measure of PQ is 9 centimeters.

if one score of 39 is changed to 40, how will the histogram change?
Answer: Histogram of 30-40 becomes slightly low and histogram of 40-50 becomes slightly high.
Step-by-step explanation:
Since we have given that
C.I. Frequency
10-20 1
20-30 4
30-40 15
40-50 14
If one score of 39 changed to 40.
Then it comes under class interval of 40-50
so, frequency under 30-40 becomes 14.
frequency under 40-50 becomes 15.
So, Histogram of 30-40 becomes slightly low and histogram of 40-50 becomes slightly high.

The line AB had midpoint (2, 5).
A has coordinates (1, 2).
Find the coordinates of B.
Answer:
The line AB, with A(Ax, Ay), B(Bx, By) and midpoint M(Mx, My) satisfying:
Ax + Bx = 2Mx
Ay + By = 2My
=>
2 + Bx = 2*1
5 + By = 2*2
=> Bx = 0
=> By = -1
=> B(0, -1)
Hope this helps!
:)
Answer:
B(3, 8 )
Step-by-step explanation:
Using the midpoint formula
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then midpoint is
[ [tex]\frac{1}{2}[/tex](x₁ + x₂ ), [tex]\frac{1}{2}[/tex](y₁ + y₂ ) ]
let the coordinates of B = (x, y ), then
[tex]\frac{1}{2}[/tex](1 + x) = 2 ( multiply both sides by 2 )
1 + x = 4 ( subtract 1 from both sides )
x = 3
and
[tex]\frac{1}{2}[/tex] (2 + y) = 5 ( multiply both sides by 2 )
2 + y = 10 ( subtract 2 from both sides )
y = 8
Thus
coordinates of B = (3, 8 )

Answer:
a) S_tot 320 cm² (cube), 282.743339 cm² (cylinder) thus the cube is a greater surface area.
b) V = 300 cm³ (cube) V = 314.159265 cm³ (cylinder) thus the cylinder has a greater volume.
Step-by-step explanation:
First solve for the cube:
length l = 10 cm
width w = 10 cm
height h = 3 cm
diagonal d = 14.4568323 cm
total surface area Stot = 320 cm²
lateral surface area S_lat = 120 cm²
top surface area S_top = 100 cm²
bottom surface area S_bot = 100 cm²
volume V = 300 cm³
Agenda: l = length
w = width
h = height
d = diagonal
S_tot = total surface area
S_lat = lateral surface area
S_top = top surface area
S_bot = bottom surface area
V = volume
Formulas for a rectangular prism or cube:
Volume of Rectangular Prism:
V = lwh
Surface Area of Rectangular Prism:
S = 2(lw + lh + wh)
Space Diagonal of Rectangular Prism:
d = √(l² + w² + h²)
_______________________________
Second we solve for the cylinder
radius r = 5 cm d/2 = 10/2 = 5 cm
height h = 4 cm
volume V = 314.159265 cm³
lateral surface area L = 125.663706 cm²
top surface area T = 78.5398163 cm²
base surface area B = 78.5398163 cm²
total surface area A = 282.743339 cm²
In Terms of Pi π
volume V = 100 π cm³
lateral surface area L = 40 π cm²
top surface area T = 25 π cm²
base surface area B = 25 π cm²
total surface area A = 90 π cm³
Agenda:
Agenda: l = length
w = width
h = height
d = diagonal
S_tot = total surface area
S_lat = lateral surface area
S_top = top surface area
S_bot = bottom surface area
V = volume
Cylinder Formulas in terms of r and h:
Calculate volume of a cylinder:
V = πr²h
Calculate the lateral surface area of a cylinder (just the curved outside):
L = 2πrh

What is one value that is a solution t
o 4x+ .8>3.2 b
ut not -6 <-5x - 1
Answer:
x = 0.8
Step-by-step explanation:
What this question asks us is that what value of x solves the first inequality but does not work for the second
Let’s solve the first inequality;
4x > 3.2-0.8
4x > 2.4
x > 2.4/4
x > 0.6
Now all values of x which is greater than 0.6 is a solution to the first inequality
Now to the second, we have;
-6 > -5x -1
Using the range of values from the first inequality;
if we say x = 0.8
Then
-6 > -5(0.8) -1
-6 > -4-1
-6 > -5
But this is not right in the real sense as actually
-5 > -6
So we can confirm that 0.8 is a solution that works for the first inequality but doesn’t work for the second
