Find the slope:

a line passes through P (3,-7) and Q (-5,5)

Answer:

x = 14 and y = 0

Step-by-step explanation:

Given that,

2x - 4y = 28 ....(1)

-x + 6y = -14​ ....(2)

Multiplying equation (2) by 2.

-2x + 12y = -28 ....(3)

Adding equation (1) and (3).

2x - 4y + (-2x) + 12y = 28 + (-28)

-4y +12y = 0

y = 0

Put the value of y in equation (2).

-x + 6(0)= -14

x = 14

Hence, the solution of the equations are x = 14 and y = 0.

Answer:

-8x2y

Step-by-step explanation:

Answer:

-8x^2y

Step-by-step explanation:

First collect like terms of xy^2 and 4xy^2(since their variables and deggres are the same) and you get: 5xy^2 - 2x^2y + 3y^3 - 6x^2y

Then collect like terms of -2x^2y and -6x^2(since their variables and deggres are the same) and you get: 5xy^2 - 8x^2y + 3y^2

The problem states "which must be the first term of her polynominal in standard form?"

That means that the polynominal Alina is talking about is -8x^2y.

i used a algebra calculator and dont know if you should trust that because it just seems like too much... sorry i tried to be helpful and prob failed immensely

Answer:

So basically you have to find the width and the length that fits based on what they're giving you.

A basic perimeter equation= P=2L+2W

24=2W+2L

divide by 2 for each variable

so

12=2w+l

6=w+l

so, w+l could be 2+4, 3+3, or 1+5. now, if you input each of these into the equation

(2w)-3=l

so 2 could be 1,2,3,4, or 5.

2(1)-3=-1.... so it can't be w=1 l=5

2(2)-3=1... it can't be w=2 l=4

2(3)-3=3.... the length is 3

SO

you're answer for the length is 3

Answer:

x=7

?=133°

Step-by-step explanation:

If the lines are parallel then:

2x+9=5x-12

3x=21

x=7

and ?=180-5x-12=180-5*7-12=180-35-12=133°

distance formula:

d = √[( x₂ - x₁ )² + ( y₂ - y₁ )²]

Given:

(0,1) and (6, -8)

x₂ = 6

x₁ = 0

y₂ = -8

y₁ = 1

Solve:

d = √[( 6 - 0 )² + ( (-8) - 1 )²]

d = √[( 6 )² + ( -9 )²]

d = √[36 + 81]

d = √[117]

d = 10.8

Choice 10.8

Answer: Theorem 10

Step-by-step explanation: Theorem 10 states that Two lines intersected by a transversal are parallel if and only if corresponding angles are congruent.

You can slide the top angle down, and it is congruent to the bottom angle, proving that it is parallel

Answer:

Option A, B, C, E are correct. Kindly verify for Option F. Option D is incorrect.

Step-by-step explanation:

The list shows the daily low temperature, in degrees Celcius, In Shawna's hometown during one week.

-2, 4,0,–3, 6, 1,4

Choose all of the inequalities that correctly compare values from the list.

Option A: 4 > 2

We know that 4 is greater than 2, so this inequality 4>2 is true.

Option B: 0 > - 2

We know that 0 is greater than -2, so this inequality 0 > -2 is true.

Option C: 6 > -4

We know that 6 is greater than -4, so this inequality 6 > -4 is true.

Option D: 0 < -3

We know that 0 is greater than -3 and not less than -3, so this inequality     0  < -3 is false.

Option E: -4 < 3

We know that -4 is less than 3, so this inequality -4 > 3 is true.

Option F: -2-3

The inequality sign is missing so, we can have either < or > sign. I am solving with both inequalities, you can consider whichever option is given to you.

So if -2 < -3

We know that -2 is greater than -3,and not less than -3 so this inequality -2 < -3 is false.

if -2 > -3

We know that -2 is greater than -3, so this inequality -2 > -3 is true.

Please check for the given statement and consider your answer.

Option A, B, C, E are correct. Kindly verify for Option F. Option D is incorrect.

Answer:

17

Step-by-step explanation:

I think I did it right

Answer:

Yes

Step-by-step explanation:

So start with (0,1) the y intercept and make the first point at (0,1)

Think of m ( the slope) as the mountain slope, This is the angle of the slope of the line

So in this case go up three on the y axis and over 1 on the x axis.

make the next point at 1 + 3 = 4 for the y value and 0 + 1 = 1 for the x value. Make the next point at ( 1, 4)

Now connect the points. creating the line

The given function is linear. Thus its rate is constant.

The rate of given function is 1.35 per unit growth in input.

Rate of the function

A linear function is a function whose graph is a straight line.

Rate of a linear function is constant.

Let we increase the input x with unity, then:

[tex]f(x) = 1.35x\\ f(x+1) = 1.35(x+1)\\ [/tex]

The difference in functions' output is the growth per unit growth in input:
[tex]f(x+1) - f(x) = 1.35(x+1) - 1.35(x) = 1.35[/tex]

Thus, the rate of the growth of function is 1.35 per unit growth in input(since the rate is constant for linear function, thus this rate is true for all values of x).

Answer:

y = -2x

Step-by-step explanation:

since the y-int starts at 0, you would go down 2 (negative) and to the right by 1, 2/1=2

use the equation y=mx+b to find the equation of a graph

m is the slope and b is the y-int

you can also use the method rise/run, where in this case, the rise (down when it’s a negative) is -2 and the run (across) is 1

2 represents the change in y and 1 represents the change in x

when finding the equation of a graph, always check the y-axis for the point then start there. that represents your y-int. then you look for a solid point and see how much units away across and up or down it is from the y-int.

in this case, i went to the point (1, -2).
