Answer:

5x² - 5x + 17

Step-by-step explanation:

(3x² + 7) + (2x² - 5x + 10)

Combine the like terms.

3x² + 2x² = 5x²

-5x does not have a like term, so there is no change.

7 + 10 = 17

Combine them, and the final equation is

5x² - 5x + 17.

Answer: 5x² - 5x + 17

Step-by-step explanation:

(3x^2+7)+(2x^2-5x+10)

3x^2 + 2x^2

-5x

7 + 10

5x^2 - 5x + 17

Answer:

1. y = 2(x + 2)

Step-by-step explanation:

if we substitute the values,

we get 6 = 2*1 + 4

6 = 6

therefore, it is correct.

The system of equations has no solution. hence option d is correct.

Equation is described as the state of being equal, and it is commonly represented as a math expression with equal values on both sides, or it refers to a problem involving numerous variables.

here, we have,

to find solution to the system:

The given equation is

y=2x+8  ..(1)

3(-2x + y) = 12  ...(2)

Substitute the y value in equation 2 from equation (1)

3(-2x + 2x+8) = 12

               3(8)=12

                24≠12

Hence the system of equations has no solution.

Answer: 25 , 10 years

Step-by-step explanation:

Suppose the present age of Artie and Carrie is x and y

According to the question, 5 years ago

[tex]\Rightarrow x-5=4(y-5)\\\Rightarrow x-4y=-15\quad \ldots(i)\\[/tex]

In five year time

[tex]\Rightarrow x+5=2(y+5)\\\Rightarrow x-2y=5\quad \ldots(ii)[/tex]

Solving (i) and (ii) we get

[tex]x=25,y=10[/tex]

The current age of Artie and Carrie is 25 and 10 years

Answer:

the area of the circle is 4π

Step-by-step explanation:

The computation of the area of the circle is shown below:

As we know that

The area of the circle = πr^2

where

diameter = 4

So radius = diameter ÷ 2

= 4 ÷ 2

= 2

Now the area of the circle is

= π × 2^2

= 4π

hence, the area of the circle is 4π

Answer:

Step-by-step explanation:∠ MON= -45°→→ angle lies in fourth quadrant.

Where, MN represents the path of rock, which is a straight line.

Taking the Horizontal and vertical component of OM,to get the coordinate of point M

The coordinate of point M will be [1.25 cos (-45°), 1.25 sin(-45°)]=

Taking O as center and Coordinates of O as (0,0) and Coordinates of M as () we get the equation of line OM as

y= tan (315°)× x

As general form of equation of line passing through the origin will be,

y= m x, where m is angle made by line with positive direction of x axis.

m= (360-45)°= 315°

→→y=-x

→→  y +  x=0

equation of line perpendicular to OM will be

→→ x -  y + k=0

Since it passes through .

→→

So, equation of initial path of stone will be:

Answer:

2(x+10)

Step-by-step explanation:

Well since sum is addition and the number and 10 are the sum, let’s make the “number“ (x) and add em up. 10+x.

Now we gotta double that sum which is basically

2(10+x)

Answer: first graph is F(x) = 0.5(x-6) (x+2)

Second graph f(x) = (x - 3) ( x + 1 )

Third graph f(x) = -2(x - 1) (x + 3 )

Step-by-step explanation:

Type functions into Desmos graphing calculator and it will plot the points for you.

PLATO

The required quadratic function shown in the graph is

f(x)=0.5(x+2)(x-6).

Let us suppose the quadratic function

[tex]f(x)=a(x-\alpha )(x-\beta )[/tex]......(1)

where α and β are roots of the quadratic equation f(x)=0

Any equation of the form [tex]ax^{2} +bx+c=0[/tex] is called a quadratic equation where a≠0

From the shown graph we can see the roots of f(x)=0 as:

[tex]\alpha =-2[/tex]

[tex]\beta =6[/tex]

So, (1) becomes [tex]f(x)=a(x+2 )(x-6 )[/tex].....(2)

Since the graph is intersecting the y-axis at (0, -6)

So,  (0, -6) will satisfy the (2)

So put x=0 and f(x)= -6 in (2)

[tex]-6=a(0-2)(0-6)[/tex]

[tex]a=\frac{-1}{2}=0.5[/tex]

So, [tex]f(x)=0.5(x+2 )(x-6 )[/tex]

Thus, the required quadratic function shown in the graph is

f(x)=0.5(x+2)(x-6).

Answer:

x = 27

Step-by-step explanation:

Given

[tex]\sqrt{2x+10}[/tex] - 6 = 2 ( add 6 to both sides )

[tex]\sqrt{2x+10}[/tex] = 8 ( square both sides )

2x + 10 = 8² = 64 ( subtract 10 from both sides )

2x = 54 ( divide both sides by 2 )

x = 27
