Answer:

C.  3, -7

Step-by-step explanation:

x^2 +4x-21 =0

Factor

What 2 numbers multiply to -21 and add to 4

7*-3 = -21

7-3 = 4

(x+7) (x-3) =0

Using the zero product property

x+7 =0       x-3=0

x+7-7=0-7     x-3+3=0+3

x = -7            x=3

Answer:

Step-by-step explanation:

[tex]x^2+4x-21=0\\\\x^2+7x-3x-21=0\\\\x(x+7)-3(x+7)=0\\\\(x+7)(x-3)=0\iff x+7=0\ \vee\ x-3=0\\\\x+7=0\qquad\text{subtract 7 from both sides}\\x=-7\\\\x-3=0\qquad\text{add 3 to both sides}\\x=3[/tex]

[tex]\large\boxed{(f+g)(x)=x^2+3x-3}[/tex]

Step-by-step explanation:

[tex](f+g)(x)=f(x)+g(x)\\\\f(x)=3x-5,\ g(x)=x^2+2\\\\\text{Substitute:}\\\\(f+g)(x)=(3x-5)+(x^2+2)=3x-5+x^2+2=x^2+3x+(-5+2)=x^2+3x-3[/tex]

Final answer:

To find (f+g)(x) for the given functions f(x)=3x-5 and g(x)=x²+2, you simply add the two functions to get (f+g)(x) = x²+ 3x - 3.

Explanation:

Adding Functions f(x) and g(x)

To find (f+g)(x), you simply need to add the values of f(x) and g(x) together for any value of x. Given that f(x)=3x-5 and g(x)=x²+2, the sum (f+g)(x) is obtained as follows:

Take the expression for f(x) and g(x):

f(x) = 3x - 5

g(x) = x² + 2

Add the two expressions together:

(f+g)(x) = f(x) + g(x)

(f+g)(x) = (3x - 5) + (x² + 2)

Combine like terms:

(f+g)(x) = x² + 3x - 3

The resulting function (f+g)(x) = x² + 3x - 3 is the sum of the two functions f(x) and g(x).

Answer:

The correct answer is D) f(x) = (x^2 - 2)/3

Step-by-step explanation:

To find an inverse function, swap x and f(x) and then solve for the new f(x). That will be the new inverse function.

f(x) = √3x+2

x = √3f(x)+2

x - 2 = √3f(x)

x^2 - 2 = 3f(x)

(x^2 - 2)/3 = f(x)

let x=length

let y=width

x/y=5/2

y=2x/5

area=length*width

area=x*y=x(2x/5)=2x^2/5

2x^2/5=360

length= 30 inches

width= 12 inches

there you go!

The dimensions of the rectangle are 20 inches in length and 8 inches in width.

The rectangle has an area of 160 square inches, and the length ratio to the width is 5:2. Let's denote the length as 5x and the width as 2x. The equation for the area of a rectangle is width * length, so we set up and solve the following equations:

Then, we multiply 'x' with the respective parts of the ratio (5 and 2) to find the length and width:

if triangles are similar then corresponding internal angles are equal

=》 x = 180-(50+60) = 70degrees

The measure of angle x is the same as the measure of angle c which is,

x = 70°

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know triangles that are similar to each other have equal measures of corresponding angles.

Given, ΔABC ≈ ΔEDF,

Therefore, m∠B = m∠E = 50° and m∠D = m∠A = 60.

So, The measure of angle x is,

x = 180 - 50 - 60. (sum of interior angles equals 180°)

x = 180 - 110.

x = 70°.

The radius of a circle with a diameter of 2 meters is 1 meter. The radius is found by dividing the diameter by two.

The question pertains to determining the radius of a circle when the diameter is given. The ring through which a leopard jumps in the circus has a diameter of 2 meters.

The formula for the diameter of a circle is d = 2r, where d is the diameter and r is the radius of the circle. To find the radius, we simply divide the diameter by 2.

Therefore, the radius of the ring is 1 meter, as r = d / 2 and thus, r = 2 meters / 2.

Step-by-step explanation:

Let the popcorn = P

Let the drink = D

2*P + 3*D = 22.25         multiply this equation by 6

12*P + 4D = 39.00

12P + 18D = 133.5          Subtract these two equations

- 14D = - 94.50               Divide by -14

-14D/-14 = -94.5/-14        Do the division

D = 6.75

=========================

12P  +  4D = 39            Substitute for D

12P + 4*6.75 = 39        Combine

12P + 27 = 39               Subtract 27 from both sides

12P + 27-27=39-27      Collect like terms

https://brainly.com/question/78672

Fractions less than 3/4 have a numerator to a denominator ratio that equals a number less than 0.75. Examples of such fractions are 1/2 and 2/3.

To determine which fraction is less than 3/4, it's important to remember that a fraction represents a division: the numerator (upper number) divided by the denominator (lower number). Fractions that are less than 3/4 have a ratio of the numerator to the denominator that results in a number less than 0.75, which is the decimal equivalent of 3/4.

For example, the fraction 1/2 is less than 3/4, because 1 divided by 2 equals 0.5, and 0.5 is less than 0.75. Similarly, the fraction 2/3 is less than 3/4, because 2 divided by 3 equals approximately 0.67, and 0.67 is again less than 0.75. Knowing the division values, even approximately, can help you quickly figure out if a fraction is less than or greater than another one.

Step-by-step explanation:

The correct answer is 12

Some factoring lets us write

[tex]a^{2b}-\dfrac1{a^b}=a^{2b}-a^{-b}=a^{-b}(a^{3b}-1)[/tex]

Then

[tex]8a^{3b}=1\implies a^{3b}=\dfrac18[/tex]

[tex]a^{2b}-\dfrac1{a^b}=a^{-b}\left(\dfrac18-1\right)=-\dfrac78a^{-b}=-\dfrac7{8a^b}[/tex]

Taking the cube root to solve for [tex]b[/tex], we find

[tex]\sqrt[3]{a^{3b}}=\sqrt[3]{\dfrac18}\implies a^b=\dfrac12[/tex]

so ultimately

[tex]a^{2b}-\dfrac1{a^b}=-\dfrac7{8\cdot\frac12}=-\dfrac74[/tex]

Answer:

The value of the given expression is    1 - 1 = 0

Step-by-step explanation:

8a^{3b} = 1   can be rewritten as (8a³)^b = 1 = (8a³)^0, which indicates that b = 0.  If b= 0, then 2b = 2(0) = 0.

Then a^(2b) = a^0 = 1, and 1/a^b = 1/1 = 1.

Thus, the value of the given expression is    1 - 1 = 0
