Sove the equation for all real solutions
-d^2-12d+4=-6d^2
Answer:
d=25 or d=2
Step-by-step explanation:
hope that helps!
Answer:
d=2/5 or d=2
Step-by-step explanation:
Step 1: Subtract -6d^2 from both sides.
−d2−12d+4−−6d2=−6d2−−6d2
5d2−12d+4=0
Step 2: Factor left side of equation.
(5d−2)(d−2)=0
Step 3: Set factors equal to 0.
5d−2=0 or d−2=0
d= 2/5 or d=2
can someone please help me

Answer:
[tex]y=-\frac{1}{4}x+4[/tex]
Step-by-step explanation:
So we pick one point from the graph
(0, 4)
[tex]y-y_{1}=m(x-x_{1} ) \\y-4=-\frac{1}{4}(x-0)[/tex]
Answer:
[tex]y-4=-\frac{1}{4}(x)[/tex]
Step-by-step explanation:
Point slope form = y − y1 = m(x − x1)
Our point is 0,4.
So the point slope is
[tex]y-4= (slope)(x)[/tex]
The slope is -1/4.
so,
[tex]y-4=-\frac{1}{4}(x)[/tex]
This is the answer.

The area of Australia is 2.95 × 106 square miles. What is the approximate average number of people per square mile in Australia? Round to the nearest person
Answer:
9 people per square mile
Step-by-step explanation:
Given that:
Area of Australia = 2.95 * 10^6 mi²
Approximate average Number of people per square mile :
This can be obtained by taking the proportion of the population of Australia and the Area of the land mass
Approximate population of Australia : 25,499,884 ( data obtained from internet)
Average number of people per square mile :
Approximate population / Land Area
25,499,884 / 2.95 * 10^6
= 8.6440284
Hence, there will be approximately 9 people per square mile.

Step-by-step explanation:
A sequence is defined recursively using the formula f(n + 1) = f(n) – 5 . Which sequence could be generated using this formula?
1, –5, 25, –125, ...
2, 10, 50, 250, ...
3, –2, –7, –12, ...
4, 9, 14, 19, ...
In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.
Answer: Choice (3) which is the sequence –2, –7, –12, ...
Here we start with -2 and subtract off 5 each time we need a new term
-2-5 = -7
-7-5 = -12
and so on.
The notation f(n+1) = f(n) - 5 tells us "subtract 5 from the nth term, called f(n), to get the next term f(n+1)"
A small pool is being drained. There are 1,320 gallons of water remaining in the pool after 2 minutes and 1, 040 gallons after 9
minutes. How long would it take for the pool to be completely drained? (1 point)
Answer: 35 minutes
Step-by-step explanation:
For us to solve the question, we have to calculate the amount of gallons of water that is drained every minute. This will be:
= (1320 - 1040) / (9 - 2)
= 280/7
= 40 gallons per minute
Since we are told that 1,320 gallons of water remain in the pool after 2 minutes. This means that the total water in the pool at the beginning was:
= 1320 gallons + (40 × 2)
= 1320 gallons + 80 gallons
= 1400 gallons
The time taken for the pool to be completely drained will be:
= Total water in pool / Gallons drained per minute
= 1400 / 40
= 35 minutes

Laney is ordering books while she is on summer vacation. Reader’s Book Club charges $4.00 per book and requires a one-time membership fee of $12. Perfect Pages requires no membership fee and charges $7.50 for each book ordered. The cost for Laney to order books depends on the number of books ordered, b. Which inequality can be used to find the minimum number of books that can be ordered so that the cost of ordering books from Reader’s Book Club is less than the cost of ordering books from Perfect Pages?

Using the inverse of sine, cosine and tangent allow us to find A missing side in a right triangle A missing angle in a right triangle The perimeter of a right triangle Triangular area
Answer:
A missing angle in a right angle.
Step-by-step explanation:
Given, the inverse of trigonometric functions sine, cosine and tangent.
To find:
The value that can be found using the inverse trigonometric functions.
Solution:
First of all, let us consider the right angled triangle attached in answer area.
Hypotenuse is AC, Base is BC and AB is the Altitude/Height of the right angled [tex]\triangle ABC[/tex].
Let us suppose all three sides are known and [tex]\angle C[/tex] is unknown.
Formula:
[tex]1.\ sin\theta = \dfrac{Perpendicular}{Hypotenuse}[/tex]
[tex]2.\ cos\theta = \dfrac{Base}{Hypotenuse}[/tex]
[tex]3.\ tan\theta = \dfrac{Perpendicular}{Base}[/tex]
Let us consider [tex]\angle C[/tex].
[tex]sin C = \dfrac{AB}{BC}[/tex]
If we taken inverse:
[tex]sin^{-1} sinC = sin^{-1} (\frac{AB}{BC})[/tex]
[tex]\Rightarrow \angle C = sin^1\frac{AB}{BC}[/tex]
Similar is the case for cosine and tangent.
Therefore, the missing angle of the right angled triangle can be calculated by the inverse of sine, cosine and tangent.

Answer:
[tex](x+5)+ \dfrac{2}{x+2}[/tex]
Step-by-step explanation:
Given
[tex]\dfrac{x^2+7x+12}{x+2}[/tex]
Required
Simplify and present your answer in
[tex]p(x)+\dfrac{k}{x+2}[/tex]
First, we need to expand and factorize the numerator:
[tex]\dfrac{x^2+7x+12}{x+2}[/tex]
Express 12 as 10 + 2
[tex]\dfrac{x^2+7x+10+2}{x+2}[/tex]
Split into two using brackets
[tex]\dfrac{(x^2+7x+10)+2}{x+2}[/tex]
Split to two fractions:
[tex]\dfrac{(x^2+7x+10)}{x+2}+\dfrac{2}{x+2}[/tex]
Factorize the numerator of the first fraction
[tex]\dfrac{(x^2+5x+2x+10)}{x+2}+\dfrac{2}{x+2}[/tex]
[tex]\dfrac{x(x+5)+2(x+5)}{x+2}+\dfrac{2}{x+2}[/tex]
[tex]\dfrac{(x+2)(x+5)}{x+2}+\dfrac{2}{x+2}[/tex]
The first fraction can be simplified to give:
[tex](x+5)+ \dfrac{2}{x+2}[/tex]
Hence, by comparison:
We have simplified the given expression to the required format of:
[tex]p(x)+\dfrac{k}{x+2}[/tex]
Which implies that:
[tex]p(x) = x + 5[/tex] and [tex]k = 2[/tex]

O -28
O 28
O 44
Answer:
- 44
Step-by-step explanation:
The absolute value function always gives a positive result, that is
| - a | = | a | = a
Given
- 2 | 6x - y | ← substitute x = - 3 and y = 4
= - 2 | 6(- 3) - 4 |
= - 2 | - 18 - 4 |
= - 2 × 22
= - 44

Answer:
TriangleJXP = Triangle HCD
Side XJ = side HC
Side CD = side JP
Side PX = HD
Step-by-step explanation:
Looking at both of the triangles you use the lines on “top” of the side. These lines represent congruence meaning that they are similar to each other.
So looking at side JP u can see that there are two lines meaning that this is the second side that is congruent to another side, side CD.
Hope this helps.
