The expression is equal to f(x) + g(x) is -10x^2 - 3x + 4, the correct option is C.
What is an expression?Expression in mathematics is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that;
The expression f(x) = -3x^2 + 4x + 4 g(x) = x(-7x – 7)
Now,
To find f(x) + g(x), you can add the two functions term by term. This gives you:
f(x) + g(x) = (-3x^2 + 4x + 4) + (x(-7x – 7))
f(x) + g(x) = -3x^2 + 4x + 4 - 7x^2 - 7x
f(x) + g(x) = -10x^2 - 3x + 4
Therefore, by the given expression the answer will be -10x^2 - 3x + 4.

Step-by-step explanation:
Two small planes start from the same point and fly in opposite directions. The first plane is flying 25 mph slower than the second plane. In 2 hrs, the planes are 470 mi apart. Find the rate of each plane.
Answer:
105 mph = rate of first plane
130 mph = rate of second plane
Step-by-step explanation:
Let r = rate of first plane
then r + 25 = rate of second plane
2r = distance of first plane
2(r + 25) = distance of second plane
2r + 2(r + 25) = 470
2r + 2r + 50 = 470
4r = 420
r = 105 mph
r + 25 = 130 mph

ILL GIVE BRAINLEST, find the value of x.
Answer:
x⁰ = 45⁰
Step-by-step explanation:
As it is given that the 2 sides of a triangle are equal, then it is an isosceles triangle.
Now, by applying the Triangle Sum Property,
x⁰ + 90⁰ + 45⁰ = 180⁰
x⁰ = 180⁰ - 135⁰
x⁰ = 45⁰
Hope it helps :)
Answer:
x = 45 degrees
Step-by-step explanation:
A triangle is always 180 degrees. One angle is already labeled 45 degrees, and we can tell this is a right triangle, so the other angle is 90 degrees. Add 45 + 90 to get 135. Then subtract 135 from 180 to get 45, which is the value of the missing angle.

find the minimum/maximum value
Answer:
Maximum Value / Vertex : (-2,16)
Step-by-step explanation:
Since the value of a is negative, we will solve for the maximum.
Finding the x-value of the vertex of the parabola is x=-b/2a:
x=-(-4)/2(-1)
x=4/-2
x=-2
Now if we plug x=-2 into the function, we'll get our y-value for the vertex:
f(-2)=-(-2)^2-4(-2)+12
f(-2)=-(4)+8+12
f(-2)=-4+20
f(-2)=16
So the vertex of our parabola is (-2,16) which is our maximum value

Answer:
Step-by-step explanation:
4x/33
The simplest fraction after calculating 3/11 times 4/9 is 12/99.
Use the concept of fraction defined as:
A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction. It can be written in the form of p: q, which is equivalent to p / q.
The given expression is:
3/11 times 4/9
It can be written as,
[tex]\dfrac{3}{11} \times \dfrac{4}{9}[/tex]
Multiply the fractions we get
[tex]\dfrac{3\times 4}{11 \times 9} \\\\\dfrac{12}{99}[/tex]
Since both the numerator and denominator have gcd 1,
Therefore, it is in simplest form.
Hence,

The hypotenuse of a right triangle measures 17 cm. One leg of the triangle measures 15 cm. Find the length of the other leg of the triangle
Need Help?
Answer:
8cm
Step-by-step explanation:
The length of the other leg can be determined using the Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
17² = 15² + b²
289 = 225 + b²
b² = 289 - 225
b² = 64
b = √64
b = 8cm

Answer:
2 , Real
Step-by-step explanation:
The quadratic equation is ,
⇒ 4x² - x - 4 = 0 .
Since it is a quadratic equation and has the highest degree of variable as 2 therefore it will have two solutions . For determining the nature of roots we will find the discriminant . The Discriminant of a quadratic equation in standard form of ax² + bx + c = 0 , is ,
⇒ D = b² - 4ac
⇒ D = (-1)² - 4 × 4 × (-4)
⇒ D = 1 + 64
⇒ D = 65 .
Since Discriminant is Greater than 0 , therefore the roots will be real .

Applying the angles of intersecting chords theorem, the measure of arc EI is: 140°.
What is the Angles of Intersecting Chords Theorem?Based on the angles of intersecting chords theorem, the measure of the vertical angle formed when two chords intersect equals half the sum of the measures of the intercepted arcs.
Given the following:
m∠EXY = 80°m∠K = 25°m(EY) = m(YI)m∠K = 1/2(2(EY) -m(JL))
25 = 1/2(2(m(EY)) -m(JL))
50 = 2(m(EY)) -m(JL)
m(JL) = 2(m(EY)) - 50
m∠EXY = 1/2(m(JL) + m(EY) [angles of intersecting chords theorem]
Substitute
80 = 1/2[2(m(EY)) - 50 + m(EY)]
2(80) = 2(m(EY)) - 50 + m(EY)
160 = 3(m(EY)) - 50
160 + 50 = 3(m(EY))
210 = 3(m(EY))
210/3 = m(EY)
m(EY) = 70°
m(EI) = 2(m(EY)) = 2(70)
m(EI) = 140°
Therefore, applying the angles of intersecting chords theorem, the measure of arc EI is: 140°.

A company sells each product they make for $78.00. They pay $2,700.00 in monthly costs, such as rent and bills, as well as $65.00 in manufacturing costs per unit. If the company sold 626 units last month, what was their total profit?

B. $5,438.00

D. $7,065.60
Answer:
B. 5438
Step-by-step explanation:
[(78-65)×626]-2700=5438
The correct option is, (B) 5438
Definition of profit:
In general, profit is defined as the amount generated from the sale of a product, which should be greater than the product's cost price. It is the amount gained from any business activity. In other words, if a product's selling price (SP) is more than its cost price (CP), it is deemed a gain or profit. It refers to the financial gain obtained when the revenue from a company activity exceeds the costs of running the business, such as taxes and expenses.
Profit formula:Profit is better expressed in terms of cost and sale price. The cost price of a product or commodity is the price at which it is purchased, whereas the selling price is the price at which it is sold. If the selling price of the commodity is more than the cost price, the company has made a profit. Profit or Gain = Selling Price – Cost Price is the formula for calculating profit.
However, when a product is sold for less than its cost price, it is referred to as a loss. As a result, loss equals cost price minus selling price.
According, to the question:
A business makes 78.00 per unit and pays 2,700.00 in monthly charges, such as rent and bills, plus 65.00 in manufacturing costs each unit. If the firm sold 626 units in the previous month.
[(78-65)×626]-2700
= 5438
Hence, The company's overall profit is 5438.
