If f(x) = –x2 + 3x + 5 and g(x) = x2 + 2x, which graph shows the graph of (f + g)(x)?
On a coordinate plane, a straight line with a negative slope crosses the y-axis at (0, 5) and crosses the x-axis at (1, 0).
On a coordinate plane, a parabola opens down. It goes through (negative 2, negative 4), has a vertex at (0, 5), and goes through (2, negative 2)
On a coordinate plane, a parabola opens up. It goes through (negative 3, 7), has a vertex at (negative 1, 2), and goes through (0, 5).
On a coordinate plane, a straight line with a positive slope crosses the x-axis at (negative 1, 0) and crosses the y-axis at (0, 5)
Answer:On a coordinate plane, a straight line with a positive slope crosses the x-axis at (negative 1, 0) and crosses the y-axis at (0, 5)
Step-by-step explanation:
(f + g)(x) = -x² + 3x + 5 + x² + 2x = 5x + 5
=> y = 5x + 5
=> the slope is positive
the line crosses the x-axis at (-1;0) and the y-axis at (0;5)

A PAIR OF JEANS MARKED AT R450 IS SOLD AT DISCOUNT OF 25%.
Original price is the jeans = Rs450
Discount = 25%
Discount amount
= 25% of 450
= 25%(450)
= 25/100 × 450
= 25/10 × 45
= 5/2 × 45
= 225/2
= Rs112.5
Price after discount
= original price - discount amount
= 450 - 112.5
= Rs337.5

Which represents the value of Point on the number line?
D
0
2
2 variable inequalities from their graphs . Please answer. Ty!
Answer:
y≤[tex]\frac{1}{3} x+1[/tex]
Step-by-step explanation:
Since the graph is facing down, We know the equation is y<mx+b
Since slope is rise/run the slope is 1/3.
Since the y intercept (The point where the line hits y) is 1, the equation is
y<1/3x+1
BUT WAIT!
The line is solid meaning that we have to include the line as part of the values. This will make the new equation
y≤[tex]\frac{1}{3} x+1[/tex]
Which equation is written in standard form?

Megan's commute to work includes an 8-mile drive and a 21-mile train ride. This expression can be used to find the total time it takes Megan to get to work, where xis her average driving speed in miles/hour. 21
Answer:
(8 / x) + (21 / y)
Step-by-step explanation:
Given that:
Average driving speed = x mph
Miles driven to work = 8 mile
Miles by train to work = 21 miles
Average train speed = y
Total time taken to get to work. :
Recall : time taken = distance / speed
Hence,
Time taken =) total distance / average driving speed)
Total time taken = (8 / x) + (21 / y) hours
Total time taken = (8 / x) + (21 / y) hours
Answer: The average speed of the train is represented by x+20. When Megan drives at an average speed of 45 mph, it takes her approximately 0.50 hour to get to work.

example of *
-the core
-tectonic plates
-the mantle
-the atmopshere
Answer:
The tectonic plates.
Step-by-step explanation:
If you look at a diagram of Earth on Google, you'll see there's the crust, the mantle, the core...etc. If the tectonic plates are apart of the crust- which is the Earth's surface, then it's safe to assume the shell of the egg is the tectonic plates.

Last season, a pair of jeans cost $42.95. This season, the price of the jeans increased by 25 percent. Later in the season, the jeans were put on sale for 25 percent off. First, guess. What do you think the sale price will be? Why? Then, calculate: How much did the jeans cost at the beginning of this season? What was their sale price? Did you get the sale price you were expecting? Why or why not? Consider what the jeans would cost if they had gone on sale by 25% first, and then had their price increased by 25%. First guess. What do you think the jeans will cost this time? Why? Then, calculate: How much will the jeans cost this time? Did you get the answer you were expecting? Why or why not?
Answer:
42.95 first price hiked 25%, then discounted by 25% : Final price = 40.28
42.95 first discounted by 25%, then price hiked by 25% : Final price = 40.27
Both are same (approx) because of same mathematical treatment
Step-by-step explanation:
If Jeans price first hiked price by 25%, then gone on sale by 25%Last season price = 42.95
This season increase in price = 25% of 42.95 = 10.73
Jeans price at beginning of this season = 53.68
Discount on sale price, this season = 25% of 53.68 = 13.42
Discounted jeans price this season = 53.68 - 13.42 = 40.28
If Jeans price first gone on sale by 25%, then price increased by 25%Last season price = 42.95
Discount on previous price = 25% of 42.95 = 10.73
Jeans price this season = 42.95 - 10.73 = 32.22
Price hike this season = 25% of 32.22 = 8.05
New jeans price this season = 32.22 + 8.05 = 40.27
The same answer is got in both cases. As, mathematically, they are same. 1st : 75% of (125% of 42.95) & 2nd : 125% of (75% of 42.95)WILL MARK BRAINLIEST! PLEASE HELP!

Pls help I will brainlest u
Answer: 11/15
Hope this helps! ^^
Answer: The answer in improper form is 11/15 or in mixed number form it is 12 1/5... I did this by dividing the Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
2/3 * 11/10
For fraction multiplication, multiply the numerators and then multiply the denominators to get
2*11/3*10= 22/30
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 22 and 30 using 22 divided by 2/30 divided by 2 which equals 11/15.
Therefore 2/3 divided by 10/11 equals 11/15
Hope this helps... Plz mark me brainliest... Stay safe and have a great weekend!!! :D

Find the GCF of the given polynomial. 16a^4b^4 + 32a^3b^5 - 48a^2b^6
Answer:
[tex]16a^2b^4[/tex]
Step-by-step explanation:
GCF= Greatest Common Factor
Given a polynomial, the GCF is the largest polynomial that will divide evenly into that polynomial.
The polynomial is
[tex]16a^4b^4 + 32a^3b^5 - 48a^2b^6[/tex]
First, we find the GCF of the coefficients:
16, 32, 48
Since 32 and 48 are multiples of 16, 16 is the GCF of the coefficients.
Now we select all the repeating variables with their smallest exponent:
[tex]a^4, a^3, a^2.\ GCF= a^2[/tex]
[tex]b^4, b^5, b^6.\ GCF=b^4[/tex]
The GCF of the polynomial is
[tex]\boxed{16a^2b^4}[/tex]
