Answer:

The answer is B: (1,2)

Step-by-step explanation:

(solved using elimination method)

-2x+y=0

y=x+1

-x+y=1

-2x+y=0

x+y=-1

-x=-1

x=1

-1+y=1

y=2

(x,y)=(1,2)

Write two polynomials with a difference of 2x2 + x + 3

Anettt [7]

Answer:

The two polynomial CAN be $5x^4+5x^3+8x^2+x+6$ and $5x^4+5x^3+8x^2+2x+13$ .

Step-by-step explanation:

Step 1: Simplify the expression:

$2*2 + x + 3$

$4+x+3$

$x+7$

Step 2: Think of a random polynomial:

$5x^4+5x^3+8x^2+x+6$

Step 3: Either add your "random polynomial" by $x+7$ or subtract it.

I want to add it so...

$5x^4+5x^3+8x^2+x+6+x+7$

= $5x^4+5x^3+8x^2+2x+13$

Check by subtracting $5x^4+5x^3+8x^2+x+6$ and $5x^4+5x^3+8x^2+2x+13$ .

$5x^4+5x^3+8x^2+2x+13$

- $5x^4+5x^3+8x^2+x+6$

$0x^4 - 0x^3 -0x^2 +x +7$ or  $x+7$

What is the y-intercept of the graph of the function f(x) = x2 + 3x + 5?

OLga [1]

Hello there!

How do you find the y-intercept?

Answer: To find the y-intercept, substitute in 0 for x and solve for y

y = x² + 3x + 5

y = (0)² + 3(0) + 5

y = 0 + 0 + 5

y = 5

Thus, the correct answer is option D (0,5)

I really hope this answer is clear enough for you to understand. If you have questions about the answer, please let me know.

As always, I'm glad to be your helper this evening~!

A cereal mixture contains Almond, Wheat, and Corn in the ratio of 3:5:7. What amount of this mixture contains 9 kilograms of Alm

Mice21 [21]

The total cereal mixture is 45 kilograms

Solution:

Given that, cereal mixture contains Almond, Wheat, and Corn in the ratio of 3:5:7

Therefore,

Almond : Wheat : Corn = 3 : 5 : 7

Let the almond present be 3x

Let the wheat present be 5x

Let the corn present be 7x

Therefore,

Total cereal mixture = 3x + 5x + 7x

Total cereal mixture = 15x

Given that mixture contains 9 kg of almond

Almond = 9

We know that,

Almond present = 3x

3x = 9

x = 3

Therefore,

Total cereal mixture = 15x = 15(3) = 45

Thus total cereal mixture is 45 kilograms

Name a pair of perpendicular lines: is line BC and AJ perpendicular: explain

wel

A pair of perpendicular lines would be line CF and line AJ.

Line BC and line AJ are NOT perpendicular because when a pair of lines are perpendicular, all angles become 90 degrees. It is obvious, in the case, if you were to slide line BC on top of line AJ, the angles will not equal 90 degrees.
