What are the solutions to f (x) = x2 + 5x

He elimination method is ideal for solving this system of equations. By which number must you multiply the second equation to el

netineya [11]

Answer:

D. Multiply the second equation by 3. The solution is x = 12, y = 10.

Step-by-step explanation:

First, look at the y variable of the first equation. It is 3y.

To solve by elimination, the variables have to add together to 0.

So, -3y needs to be added to -3y to eliminate the y variable.

The second equation has the y variable of -y, so it has to be multiplied by 3.

So, answer choice D is the correct answer.

What is the amount of money whose 25percent is Rs 350

34kurt

Answer:

Rs 1400

Step-by-step explanation:

Let us take the required number be x. According to question ,

=> 25% of x = Rs 350

=> 25/100 × x = Rs 350

=> x = Rs 350 × 100 / 25

=> x = Rs 1400

<h3>• Hence the required answer is Rs 1400.</h3>

.A number consists of 3-digit numbers. The ones and the hundreds place digits are both divisible by 3. The tens and ones place d

Westkost [7]

Answer:

946

Step-by-step explanation:

xyz- the searched number where x depicts hundreds, y - tens and z describes ones. Both X and Z are divisible by 3 .Y and Z are divisible by 2

Z is divisible by 3 and divisible by 2, the only digit which is possible is 3*2=6

6-2=4 - tens digit Y

The hundreds place digit is 3*3=9

My question is on the image it would mean the world to me if you could help

stiks02 [169]

Answer:

a. Slope of f(x) is greater than g(x)

b. y-intercept of f(x) is less than the y-intercept of g

Step-by-step explanation:

Function f(x)

Given the function f(x)

x f(x)

-3 -0.5

-2 0

-1 0.5

0 1

Finding the slope between any two points

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-3,\:-0.5\right),\:\left(x_2,\:y_2\right)=\left(-2,\:0\right)$

$m=\frac{0-\left(-0.5\right)}{-2-\left(-3\right)}$

$m=0.5$

Thus,

The slope of f(x) = 0.5

We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the given point (0, 1), we can easily observe that at x = 0, the value of y = 1.

Thus, the y-intercept of f(x) = 1

Function g(x)

Taking two points from the given graph of g(x)

(1, 0)

(0, 2)

Finding the slope between (1, 0) and (0, 2)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(1,\:0\right),\:\left(x_2,\:y_2\right)=\left(0,\:2\right)$

$m=\frac{2-0}{0-1}$

Refine

$m=-2$

Thus,

The slope of g(x) = -2

We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the given point (0, 2), we can easily observe that at x = 0, the value of y = 2.

Thus, the y-intercept of g(x) = 2

Conclusion:

FOR function f(x)

The slope of f(x) = 0.5

The y-intercept of f(x) = 1

FOR function gx)

The slope of g(x) = -2

The y-intercept of g(x) = 2

Thus:

a. Slope of f(x) is greater than g(x)

b. y-intercept of f(x) is less than the y-intercept of g
