x-5y=-6
7x-3y=42
Solve each system using substitution

Answers

Answer 1

Answer:

Step-by-step explanation:

To solve the system of equations using substitution, we first need to isolate one of the variables in one of the equations. We can start by solving the first equation for y:

x - 5y = -6

y = (x + 6) / 5

Now we can substitute this expression for y into the second equation:

7x - 3y = 42

7x - 3((x + 6) / 5) = 42

Simplifying and solving for x:

(35/5)x - (3/5)x - 18/5 = 42

32x = 210+18

x=57/8

Now we can substitute this value of x back into the first equation to find the value of y:

y = ((57/8) + 6) / 5

y = 21/8

So the solution of the system is (x, y) = (57/8, 21/8).

For the exponential function f(x)= a(b)' we know that f(3) =17 and f(7)=3156. Which of the

following is closest to the value of b?

Answers

The closest to the value of b is 3.6912.

An exponential function is a Mathematical function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.

f(x)=a(b)^x and we know that f(3)=17 and f(7)=3156. what is the value of b

Set up both equations with values

When x = 3, f(3) = 17, so we have a(b)^3 = 17

When x = 7, f(7) = 3156, so we have a(b)^7 = 3156

Isolate a in each equation

a = 17/(b)^3

a = 3156/(b)^7

Now set them equal to each other

17/(b)^3 = 3156/(b)^7

Cross Multiply

17b^7 = 3156b^3

Divide each side by b^3

17b^4 = 3156

Divide each side by 17

b^4 = 185.6471

b = 3.6912

Therefore, the closest to the value of b is 3.6912.

Answers

Answer:

b. To express p(x) as a product of linear factors using long division, we divide p(x) by (x - 2) and get a quotient of (x + 5) and a remainder of 0. This means that p(x) = (x - 2)(x + 5)

e. To solve p(x) = 0, we set each factor equal to zero and find the solutions:

x - 2 = 0, x = 2

x + 5 = 0, x = -5

Thus, the solutions to the equation p(x) = 0 are x = 2 and x = -5.

a. To show that x-2 is a factor of p(x), we can use synthetic division or polynomial long division.

Tan2x = (2*15/17)/(-12/17) = -5/12
Since sinx = 15/17 and x terminates in quadrant 2, then x = -3π/17. The trigonometric identities for double angles can be used to solve for sin2x, cos2x, and tan2x.
Sin2x = 2*sinx*cosx = 2*(15/17)*(-12/17) = -30/289
Cos2x = 2*cosx*cosx - 1 = 2*(-12/17)*(-12/17) - 1 = -5/289

2(3b+6) =78 : Answer is 11
-2(6c-3) = -72 : Answer is 6.5

Check Right and Left side of the equation

Answers

The right side of the first equation is 78 and the right side of the second equation is -72. Both sides of the equations are constants (numbers with no variable in them)

The left side of the first equation is 2(3b+6) and the left side of the second equation is -2(6c-3). Both sides of the equations are products of a constant and a variable or a sum/difference of variables.

To find the value of b and c in the equation, you need to solve the equation.

For the first equation:

2(3b + 6) = 78

3b + 6 = 39

3b = 33

b = 11

For the second equation:

-2(6c - 3) = -72

6c - 3 = 36

6c = 39

c = 6.5

So, the value of b is 11 and the value of c is 6.5

How do you write 2 more than 3 times?.

Answers

The correct equation to write 2 more than 3 times is 3x + 2.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Let us assume that, the number is 17 .

So,

Three time of x = 3 * x = 3x

then,

→ 2 more than three time of x = (3x + 2)

given that, 2 more than three time of x is equal to 17 .

therefore,

→ 3x + 2 = 17

→ 3x = 17 - 2

→ 3x = 15

→ x = 5 (Ans.)

Hence, the required number is 5 .

Verification :-

→ 2 more than three times of 5 = 17

→ 3 * 5 + 2 = 17

→ 15 + 2 = 17

→ 17 = 17 .

The solutions of the system of linear equations 3x+ 4y= 10 2x+ 2y= 2 can be found by using the method of substitution or elimination.Solve one of the equations for one of the variables in terms of the other variable.

Let's solve the first equation for x: 3x + 4y = 10 3x = -4y + 10 x = -4/3y + 10/3

Substitute this expression into the other equation and solve for the remaining variable.

Find, correct to the nearest degree, the three angles of the triangle with the given vertices.

Answers

The three angles of the triangle can be found by using the formula for the sum of angles of a triangle, which is 180°. Then, the measure of angle A + angle B + angle C = 180°.

1. Using the sum of angles formula, angle A + angle B + angle C = 180°

2. Use the Law of Cosines to calculate the angle between two sides of the triangle.

3. Subtract the sum of those two angles from 180° to find the measure of the third angle.

The three angles of a triangle can be found using the sum of angles formula, which states that the sum of the angles of a triangle equals 180°. This means that angle A + angle B + angle C = 180°. To find the individual angles, we can use the Law of Cosines which states that c2 = a2 + b2 - 2ab cos C, where C is the angle between two sides of the triangle. This formula allows us to calculate the angle between two sides of the triangle. Once we have calculated the sum of the two angles, we can subtract this sum from 180° to find the measure of the third angle. For example, if the sum of the two angles is 120°, then the third angle would be 180° - 120° = 60°. This method allows us to find the three angles of the triangle with the given vertices.

The complete question is:

What is the slope of 4x + 2y = -12?

2/3 x 22/7 x 5.25 x 5.25 x 5.25 =?

Please explain this step by step because i am weak at math.

Answer:

Step-by-step explanation:

step 1:  NUMERATOR:

                                  2 x 22 x (5.25)³

                               = 44 x 144.703125

            Numerator = 6366.9375

step 2: DENOMINATOR:

                                     = 3 x 7

           Denominator    = 21

step 3: CALCULATION:
                                      = numenator / denominator

                                      = 6366.9375 / 21

                        Answer =  303.1875

RAMP The height of a ramp can be
modeled by f(x) = -1/2 x − 241 +2,
where f(x) is the height of the ramp, in
feet, and x is the distance from one
side of the ramp. Graph the function
on a separate piece of paper. Find and
interpret the key features of the graph
in the context of the situation.
The vertex is located at ( , )This means that the maximum height of the ramp is _ feet when the distance from one side is _ feet. Because the distance cannot be negative, and the ramp is _ feet long, the relevant domain is {x | 0 ≤ x ≤ __}.

Because the height cannot be negative, and the ramp is _ feet tall, the relevant range is {y | 0 ≤ y ≤ __ }. The graph is symmetric in the line x = _ This means that the height from a distance of 0 to _ feet away from one side of the ramp is the same as the height from a distance of _ to _ feet away from one side of the ramp.

It is a downward parabola, which means the height of the ramp decreases as the distance from one side of the ramp increases.

What is the parabola?

A parabola is a symmetric, U-shaped geometric curve that can be defined as the set of all points that are equidistant to a fixed point (the focus) and a fixed line (the directrix). It is a conic section, which means it is the intersection of a plane and a cone. In algebraic terms, a parabola can be defined as the graph of a quadratic equation of the form y = ax^2 + bx + c, where a, b, and c are constants.

The height of a ramp can be modeled by f(x) = -1/2 x − 241 +2, where f(x) is the height of the ramp, in feet, and x is the distance from one side of the ramp. To find the vertex of the parabola, we need to complete the square.

The vertex is located at (-b/2a, f(x) + (b^2-4ac)/4a) = (-1/2, -241 +2) = (0, -240)

This means that the maximum height of the ramp is -240 feet when the distance from one side is 0 feet.

Because the distance cannot be negative, and the ramp is unknown length, the relevant domain is {x | 0 ≤ x ≤ unknown}.

Because the height cannot be negative, and the ramp is unknown tall, the relevant range is {y | 0 ≤ y ≤ unknown }.

The graph is symmetric in the line x = 0. This means that the height from a distance of 0 to an unknown feet away from one side of the ramp is the same as the height from a distance of an unknown to an unknown feet away from one side of the ramp.

It is a downward parabola, which means the height of the ramp decreases as the distance from one side of the ramp increases.
