Work out the size of obtuse angle DOF, giving a reason for your answer.

Answer:

Here, the given function,

Since, the leading coefficient is negative, and degree is odd,

Thus, the end behaviour of the function is,

Therefore, the graph rises to the left and falls to the right.

Now, when f(x) = 0

That is, graph intercepts the x-axis at (3, 0), (1, 0) and (-1, 0).

When x = 0,

That is, graph intersects the y-axis at ( 0, -3),

Also, for 0 > x > -1 , f(x) is decreasing,

For 2.55 > x > 0, f(x) is increasing,

For 3 > x > 2.55, f(x) is decreasing,

It's the first one...!!!

Answer:

(-4, -5)

Step-by-step explanation:

-4x + 2y = 6

-4x + 2(x - 1) = 6

-4x + 2x - 2 = 6

-2x - 2 = 6

-2x - 2 + 2 = 6 + 2

-2x = 8

-2x/-2 = 8/-2

x = -4

------------------------

y = x - 1

y = -4 - 1

y = -5

-------------------------

-4(-4) + 2(-5) = 6

16 + -10 = 6

6 = 6

Answer: it's y squared by 2-81

Answer: -3x + 1

Step-by-step explanation:

Looking at the y table, when we subtract 1 from them, they become multiples of -3

So we multiply x by -3 then add 1

Answer:

[tex]y=3x-15[/tex]

Step-by-step explanation:

Slope intercept form: [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis)

1) Find the slope of the line ([tex]m[/tex])

When it comes to parallel lines, they will always have the same slope but different y-intercepts. The given equation is [tex]y=3x-5[/tex]. Because 3 is in the place of m, we know that the slope of the line is 3. Therefore, the slope of the line parallel to it will also be 3. So far, this is what our equation looks like:

[tex]y=3x+b[/tex]

2) Find the y-intercept ([tex]b[/tex])

To find the y-intercept, we plug the given point (4,-3) into the equation we currently have and solve for b.

[tex]y=3x+b\\-3=3(4)+b\\-3=12+b[/tex]

Subtract both sides by 12

[tex]-3-12=12+b-12\\-15=b[/tex]

Therefore the y-intercept of our line is -15. Plug -15 back into the original equation as b.

[tex]y=3x+(-15)\\y=3x-15[/tex]

I hope this helps!

Answer:

2. $68.04

Step-by-step explanation:

Step-by-step explanation:

16x+16x+13x= 180

45x= 180

x= 4

16x= 64°

16x = 64°

13x= 52°

Answer:

m∠P=143° and m∠Q=37°

Step-by-step explanation:

(2x-5)+(7x-4)=180°

9x-9=180

9x=189

x=21

2(21)-5=37

7(21)-4=143

Step-by-step explanation:

Answer:

We always start with the x because in the alaphbet x is before y. So it says x=1 and the graph is skipping by 2 so in the middle of where the interact and beside positive 2 on the x row is where the 1 is so you keep it there for now. Now for the y you can see the middle where the interact well that is 0 so you have to keep the dot on the x place because if it said y=2 we would move it but is says 0 so we dont move it!

Answer:X = Daniel spent

Y = Tracy spent

Tracy spent = Y

Put it all together

Y=3X-38

Answer:

This is not possible

W = width of cardboard to start with

W+6 = length of cardboard to start with

H =2    (height of finished box)

volume = W x L x H = 14 in^3

if H=2 in, then the area of the base before cutting out the 2x2 corners is W x L = 7 in^2

This is not enough area to cut out the 4 corners of 2x2 each, which would be 16 in^2

Answer:

Step-by-step explanation:

Side lengths in an isosceles right triangle have the reduced ratios ...

  1 : 1 : √2

Yours have the ratios ...

  9 : x : y

If you multiply the reduced ratios by 9, you can find the values of x and y.

  9 : 9 : 9√2 = 9 : x : y

  x = 9

  y = 9√2
