Answer:
5x⁴ + 7x or x(5x³ + 7 )
Step-by-step explanation:
Given expression:
5x⁴ - 7(-x )
To simplify this expression, we have to follow the order of operation PEMDAS;
Parentheses, Exponents, Multiplication, Division, Addition and Subtraction
5x⁴ - 7(-x ) = 5x⁴ + 7x
Since x is common to both terms;
= x(5x³ + 7 )
So the simplified version can be 5x⁴ + 7x or x(5x³ + 7 )

Helpppp!!! Can somebody give me 2 problems and solve them so I can do this assignment so I can pass , has to be before 12!!
3(2x+5)=3
3 • 2x] + [3 • 5] = 3
6x + 15 = 3
6x = –12
x = –2
2x – 2(3x – 2) = 2(x –2) + 20
2x – 2(3x – 2) = 2(x –2) + 20
2x – 6x + 4 = 2x – 4 + 20
– 4x + 4 = 2x + 16
–4x + 4 – 4 –2x = 2x + 16 – 4 -2x
–6x = 12
x = –2

Step-by-step explanation:
g(x) = -x2 + 2x - 9
g(-4)
Answer:
-33
Step-by-step explanation:
g(x) = [tex]- x^{2} + 2x - 9\\[/tex]
g(-4) = [tex]- ( -4)^{2} + 2 * (-4) - 9[/tex]
= - 16 - 8 - 9 = - 33

pls show me how to solve it
the total cost of playing an online game is $170. the base cost of the game is $50, and it costs $30 per month to play the game. The equation 170=30x+50 can be used to find the x (the number of months you play the game). How many months will you get to play the game if the total cost is $170?
Answer:
x = 4 (4 months)Step-by-step explanation:
170 = 30x + 50
Step 1: Subtract 50 from both sides170 - 50 = 30x + 50 - 50
120 = 30x
Step 2: Divide by 30 on both sides120/30 = 30x/30
x = 4
Step 3: Check170 = 30(4) + 50
170 = 120 + 50
170 = 170 ✔️
x = 4 (4 months)The price of a dress was reduce from $20 to $12. By what percentage was the price of the dress reduced?
Answer:
40%
Step-by-step explanation:
12$ out of the original 20$ = 12/20
12/20 = .6 (60%)
1=100%
if 12/20 = 60% then 100% - 60% = 40%
$20-40% is $12

The equation of the line in slope Intercept form is
Answer:
y = 60x + 40
Step-by-step explanation:
It is in the form of
y = mx + b
m is the slope
b is the y intercept.
The y intercept is 40, so it will be y = mx + 40.
The slope is 60, so y = 60x + 40!

If y=15 when x=5, find y when x=7, given that y varies directly with x.
Answer:
when x = 7, y = 21
Step-by-step explanation:
This is about direct variation. If y varies directly with x, then there is a constant factor of variation, k. The constant of variation can be found by ʸ⁄ₓ
k = ʸ⁄ₓ
k = ¹⁵⁄₅ = 3
Now that we have found k, we simply multiply x by it to find y (this is because y is directly proportional to x). We plug in our x = 7 to find y at this point.
y = 3x
y = 3(7)
y = 21

Answer:
66.4°
Step-by-step explanation:
→ Find the side which is not given
Hypotenuse = 15 cm
Opposite = ?
Adjacent = 6 cm
→ Utilise the formula triangle with out opposite in it
Cos⁻¹ = Adjacent ÷ Hypotenuse
→ Substitute in the terms
Cos⁻¹ = 6 ÷ 15 ⇔ 66.4°

Answer:
2/8 and the simplified version is 1/4
Step-by-step explanation:
Answer:
2/8
Step-by-step explanation:
First you know that it is a eight- sided die. 2 or 5 are two numbers so it is 2/8.
you put all of the numbers and count them up on the top as numerators ex: 2/ Then the number of the sided die as the denominator.ex: 2/8 Hope this helped.

determine the vertex of y=4(x-25)2+ 91
Answer:
(25, 91)Step-by-step explanation:
y = a(x - h)² + k ← vertex form of the equation of the parabola with vertex (h, k)
So y = 4(x - 25)² + 91 means:
a = 4
x - 25 = x - h ⇒ - 25 = - h ⇒ h = 25
+ 91 = + k ⇒ k = 91
Therefore vertex is:
(25, 91)
