Use the the factor theorem to determine wether the first polynomial is a factor of the second. X-3; 2x^2-4x+30

Firdavs [7]

Given the polynomial function

$P(x)=2 x^{2} -4x+30$

If (x-3) is a factor of P(x), then

$P(x)=2 x^{2} -4x+30=(x-3)*Q(x)$ , for some polynomial Q of 1st degree,

Then according to the factor theorem P(3)=0, because P(3)=(3-3)Q(x)=0*Q(3)=0.

Check

$P(3)=2 (3)^{2} -4(3)+30=18-12+30=36$ ≠0

we see that P(3) is not 0, so (x-3) is not a factor of P(x).

Which statements are true about the ordered pair

Lostsunrise [7]

Answer:

-The ordered pair (-1, 5) is a solution to the first equation because it makes the first equation true.

-The ordered pair (-1, 5) is a solution to the second equation because it makes the second equation true.

-The ordered pair (-1, 5) is a solution to the system because it makes both equations true

Step-by-step explanation:

The correct question is

Which statements are true about the ordered pair (−1, 5) and the system of equations?

x+y=4

x−y=−6

we know that

If a ordered pair is a solution of a equation, then the ordered pair, must satisfy the equation (makes the equation true)

If a ordered pair is a solution of the system of equations, then the ordered pair, must satisfy the equations of the system (makes both equations true)

we have

$x+y=4$ ----> first equation

$x-y=-6$ ----> second equation

step 1

Verify if the ordered pair satisfy the first equation

Substitute the values of x and y of the ordered pair in the first equation

For x=-1, y=5

$-1+5=4$

$4=4$ ---> is true

The ordered pair satisfy the first equation

The ordered pair is a solution to the first equation because it makes the first equation true

step 2

Verify if the ordered pair satisfy the second equation

Substitute the values of x and y of the ordered pair in the second equation

For x=-1, y=5

$-1-5=-6$

$-6=-6$ ---> is true

The ordered pair satisfy the second equation

The ordered pair is a solution to the second equation because it makes the second equation true

therefore

The ordered pair (-1, 5) is a solution to the system because it makes both equations true

Please help with those two?

german

First question:

When you bisect an angle, you create two new equal angles, both measuring half of the original angle. So, if the original angle was 52°, the two angles will be 52/2=26 degrees each.

Note: the picture is not very clear, and I'm not sure the original angle is 52°. It it's not, just divide by 2 whatever measure the angle is.

Second question:

Focus on triangles RQP and RSP:

They are both right, because Q and S are right angles
We are given QP=SP
They share the side RP

So, they are congruent. This implies that angle SRP is 50° as well, and then

QRS = QRP+SRP = 50°+50°=100°

Very counfused on this

Lilit [14]

Answer:

Step 1: Fill three gallon jug

Step 2: Pour the water from the three gallon to the five gallon jug

Step 3: Refill three gallon jug

Step 4: Pour three gallon jug into five jug until full (this leaves one gallon in the three gallon tank.

Step 5: Dump out the water in the five gallon jug

Step 6: Pour the 1 gallon of water into the five gallon jug

Step 7: Refill the 3 gallon jug

Step 8: Pour the 3 gallons into the five gallon jug (3 + 1 = 4)

Step 9: Place jug on scale.

Hope this helps!
