Answer:
2x + 3
Step-by-step explanation:
So, the equation here is:
[tex]\frac{2x^2 - 5x - 12}{x - 4}[/tex]
And so, using this we can set up our synthetic equation using the dividends as the coefficients of the equation, which are 2, -5, and -12; and the divisor 4, which derives from -4.
It's a bit hard to create a table here, so I'll just write out the values and hope you piece it together.
4 | 2 -5 -12
| 2 8 12
2 3 0
Thus, we are given our coefficients for our desired equation.
2x + 3
And we can ascertain this to be the answer by working the converse.
(2x + 3)(x - 4)
2x² - 5x - 12

Find g(f(x)
Answer:

Step-by-step explanation:
[tex]g(x)=x-3 \\ f(x) = -2x + 2 \\ g(f(x)) = ( - 2x + 2) - 3 \\ g(f(x)) = - 2x + 2 - 3 \\ g(f(x)) = - 2x - 1[/tex]
An apple costs $2.00 more than amango. The total cost of
three apples and a mango is $50.00.
put it in algebra pls
Answer:
,,,,,,, ,,,,,,,,,,,,,,,,,
Answer:
1 mango = 11 dollars
1 apple = 13 dollars
Step-by-step explanation:
Let [tex]a[/tex] be equal to the cost of an apple.
Let [tex]m[/tex] be equal to the cost of a mango.
1) Create equations
An apple costs $2.00 more than a mango.
⇒ [tex]m+2=a[/tex] (the cost of a mango + 2 dollars = cost of an apple)
The total cost of three apples and a mango is $50.00.
⇒ [tex]3a+m=50[/tex] (3 apples*the cost of 1 apple + cost of 1 mango = 50 dollars)
2) Solve for m and a
[tex]3a+m=50[/tex]
Substitute a with [tex]m+2[/tex]
[tex]3(m+2)+m=50\\3m+6+m=50\\4m+6=50[/tex]
Subtract both sides by 6
[tex]4m+6-6=50-6\\4m=44[/tex]
Divide both sides by 4
[tex]\frac{4m}{4}=\frac{44}{4} \\m=11[/tex]
Therefore, the cost of 1 mango is 11 dollars.
[tex]m+2=a[/tex]
Substitute m with 11 to solve for a
[tex]11+2=a\\13=a[/tex]
Therefore, the cost of 1 apple is 13 dollars.
I hope this helps!
While standing on top of a hill at a ski resort, Lisa spots the ski lodge below. If the vertical height of the hill is 1209 feet and the angle of depression is 53°, what distance must Lisa ski in order to reach the lodge?
Answer:
1514 feet
Step-by-step explanation:
We solve using the trigonometric function of Sine
sin θ = Opposite/ Hypotenuse
θ = Angle of depression = 53°
Opposite = Vertical height = 1209 feet
Hypotenuse = x =??
Hence,
sin 53 = 1209 feet/x
Cross Multiply
sin 53 × x = 1209 feet
x = 1209 feet/ sin 53
x = 1513.8320107 feet
Approximately = 1514 feet
Therefore, the distance Lisa must ski to reach the lodge is 1514 feet

I think the bigger number would be 203 but I don't knowwww
Step-by-step explanation:
Let the number of psychology books be 'x'.
and that of sociology books be 'y'.
x + y = 317 (given)
Number of sociology books sold was 89 less than that of psychology books.
y = x - 89
Which means,
x + x - 89 = 317
2x = 317 + 89
2x = 406
x = 406/2 = 203
y = 203 - 89 = 114
Hence, 203 psychology books and 114 sociology books were sold.

Answer:
6) x = 36°, y = 18°
7) z = 7°
Step-by-step explanation:
6) 2x + 3x = 180°
5x = 180°
x = 36°
4y = 2x = 72°
y = 18°
7) 2z + 4 = 4z - 10
2z = 14
z = 7

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas. This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Marie charges a $10.75 base fee for each dog she walks,
and, additional $7.10 per hour that she walks the dog.
Each day she spends $5.50 on dog treats.
So, if Marie works for 4 1/2 hour then she can earn
= 10.75 + 4 1/2 x 7.1 - 5.5
= 10.75 + 4.5 x 7.1 - 5.5
= $37.2.
Hence, Marie would earn $37.2.

£770 is divided between Mark, Henry & Gavin so that Mark gets twice as much as Henry, and Henry gets three times as much as Gavin. How much does Henry get? £770 is divided between Mark, Henry & Gavin so that Mark gets twice as much as Henry, and Henry gets three times as much as Gavin. How much does Henry get?
Answer:
henry gets 231
Step-by-step explanation:
my head
Answer:
231
Step-by-step explanation:
Let's consider that Gavin got X pounds.
Then Henry gets 3 times as much as Gavin => 3X
And Mark gets twice as much as Henry => 2 * 3X
Together they get 770, so:
X + 3X + 2*3X = 770
10X = 770 => X = 77
As we mentioned, Henry gets 3X, so
3X = 3 * 77 = 231

In the diagram of triangle FJH below, KG || JH, FK=3, KJ=15, and FG=4. What is the length of FH?
Given:
In triangle [tex]FJH,KG\parallel JH, FK=3, KJ=15,\text{ and }FG=4.[/tex]
To find:
The length of [tex]FH[/tex].
Solution:
Basic proportionality theorem(BPT): If a line intersect the two sides of a triangle and parallel to third side of the triangle, then it divides the sides proportionally.
In triangle [tex]FJH,KG\parallel JH[/tex].
Using BPT, we get
[tex]\dfrac{FK}{KJ}=\dfrac{FG}{GH}[/tex]
[tex]\dfrac{3}{15}=\dfrac{4}{GH}[/tex]
On cross multiplication, we get
[tex]3\times GH=4\times 15[/tex]
[tex]GH=\dfrac{60}{3}[/tex]
[tex]GH=20[/tex]
Now,
[tex]FH=FG+GH[/tex]
[tex]FH=4+20[/tex]
[tex]FH=24[/tex]
Therefore, the length of FH is 24 units.
