what is the slope of (4,1) and (6,-1)
Answer:
slope = -1
Step-by-step explanation:
you subtract the y-values (-1-1=-2) then subtract the x-values (6-4=2) then divide the sum of the y-values by the sum of the x-values
[tex]\frac{-2}{2}[/tex] which simplifies to a slope of -1

Solve the equation: [tex]x^{2} +5x+6=0[/tex]
I know [tex]x^{2} +5x+6=(x+3)(x+2)[/tex] (that was part a) but I don't know where to go from here!
Step-by-step explanation:
but then you did already the most work.
because just think : when is the expression
(x+3)(x+2) equal to 0 ?
only, if at least one factor of the multiplication is equal to 0.
you know, for example, 5×0 = 0, or 0×3 = 0.
that means either (x+3) or (x+2) must be 0.
x + 3 = 0
x = -3
and
x + 2 = 0
x = -2
and there you have it.
a quadratic equation (with the highest x exponent is 2) has 2 solutions for being 0.
and this one here has the 2 solutions
x = -3 and
x = -2
again, by finding the factors you did already the biggest and most difficult part yourself. congratulations !

Answer:
Step-by-step explanation:
Use DESMOS to plot both lines (attached).
If you make your own lines on the graph paper, pick two points for each line and connect them with a ruler. Both are straight lines, so we only need two points.
Pick any two values of x and solve each equation for y. I picked x = 1 and 3
EQ1: y=2x-2
EQ2: y=-x+4
Value of y EQ1 EQ2
x =1 0 3
x =3 4 1
Plot the points (1,0) and (3,4) for EQ1.
Do the same for EQ2: (1,3) and (3,1)
The attached graph shows these points. Note that one can draw stright lines for both equations using only these two points.

Answer:
-47
Step-by-step explanation:
First term in the sequence is given as 30. The common difference (difference between first term and next term) is -7. Since we are looking for the 12th term we can do 30 - (11 * -7) = -47. It's 11 * -7 because we already are given one term in the problem statement.

Step-by-step explanation:
[tex]81x^{3}-36x[/tex]
9(9x³ - 4x)
9x(9x² - 4)
Since both terms are perfect squares factor using the difference of squares formula, a² - b² = (a + b) (a - b)
Therefore, 9x(3x-2) (3x+2)
Answer:
81z^3-36z = 9z(3z-2)(3z+2)
Step-by-step explanation:
(81z^3-36z)=9z(9z^2-4)
9z(9z^2-4)=9z(3z-2)(3z+2)
81z^3-36z=9z(3z-2)(3z+2)
81z^3-36z=9z(3z-2)(3z+2)
Which of the following is a solution to the inequality below?19 ≥ 5k + 6
Answer:
k ≥ 13/5 or k ≥ 2.6 ( same thing )
Step-by-step explanation:
symbol stays the same throughout (≥)
subtract 6 from both sides of the symbol ( 13 ≥ 5k)
divide both sides by 5 (13/5 ≥ k )
your answer can be written as k ≥ 13/5 or k ≥ 2.6

3÷5 = 0.6

5 cannot go into 3 so the answer is a decimal
then add a zero at the end of 3 to make 30

and 5 can go into 30, 6 times so you add a 6 to make 0.6

(-5+2)•(-1/2)
I don’t know how to do this problem. Would anyone be able to assist? Thanks!
Answer:
3/2 or 1 1/2 or 1.5
Step-by-step explanation:
first do the equations in each parentheses:
(-5+2) = -3
(-1/2) = -1/2
then multiply both sides:
-3 • -1/2 (which is the same as -3 • -1 over 2)
= 3/2 or 1 1/2 or 1.5
What is the product?

Answer:
Step-by-step explanation:
Let's start by looking at the graph of the two equations.
Since you are not looking for where the lines cross, I have chosen any 3 points for each equation almost randomly. I have not used either the x or y intercepts except once.
As a sample for the method of calculation
Let x -2y = 4
Let x = -2. Find y and put it in the table
-2 - 2y = 4 Add 2 to both sides
-2+2-2y = 4 + 2 Combine
-2y = 6 Divide by -2
y = 6/-2
y = - 3
Put that in the table under the first equation.
The other 5 points are done the same way.
An art gallery is increasing the asking price of its paintings by 60%. A painting now costs $400.00. How much was the painting before the increase??
$
Answer:
$250
Step-by-step explanation:
The goal here is to find the cost of the painting BEFORE the 60% increase.
To find the cost of the painting, we must take in the information we already have:
Increase percent: 60%
Original price: unknown
Price after increase: $400
$400 is the price of the painting AFTER the increase has been added. So this equals the cost of the painting before the increase, plus the total amount of the increase (which is 60% of the original price).
The total must be (100% + 60% = 160%) 160% of the original painting price.
To find the original price, we must divide the increased price by the new percentage (160%). But how do we get here?
Well, we have 160% and our (fraction) $400/1%. We will have to switch the 160% and the 1%, giving us..
1% $400/160%
We take 400/160, which is 2.5. But this is only 1% of the original price! We want 100%.
So now, we multiply the 2.5 by 100 to get our answer: $250.

Find the value of y to the nearest tenth.
Step-by-step explanation:
the easiest approach seems to be the law of sines :
a/sin(A) = b/sin(B) = c/sin(C)
where the sides and the angles are always opposite of each other.
we have here a right-angled triangle, so the angle opposite of 10 is 90 degrees.
10/sin(90) = 10/1 = 10 = y/sin(37)
y = 10×sin(37) = 6.018150232 ≈ 6.0
