Answer:

An slope-intercept form equation is written as y=mx+b. “m” is the slope and ”b” is the y-intercept. When we substitute the given values, the equation of the line in slope-intercept form is y=-1/4x+1.

Answer:

4 questions

Step-by-step explanation:

90% is the same as multiplying a number by 0.9. Let's say the number of questions on the quiz is x. This means the amount she got right was 0.9x. We are given this is 36, so we can set them equal and simplify:

0.9x = 36

x = 40

She must have gotten 40 - 36, or 4 questions wrong.

Answer:

A. 2x - 1

Step-by-step explanation:

We want the price of each notebook, so we will get this equation.

(4x^2 + 2x + 1) / (8x^3 - 1)   [ The " / " sign means I wrote as a fraction. ]

After that, we will use this method to factor ( 8x^3 - 1 ).

a^3 - b^3 = ( a - b )( a^2 + ab + b^2 )

1 can be wrote as 1^3 as we still get the same answer.

8^3 - 1^3 = ( 2x - 1 )( 4x^2 + 2x + 1)

So, we will get this.

(4x^2 + 2x + 1) / ( 2x - 1 )( 4x^2 + 2x + 1)

Now, we can cross out the ( 4x^2 + 2x + 1 ).

We will be left with 1 / ( 2x - 1 ).

Flip it and we will get ( 2x - 1 )

And that is the answer.

I hope it helps.

Answer:

sqrt(95)

Step-by-step explanation:

c^2 = a^2 +  b^2

12^2 = 7^2 + b^2

144 = 49 + b^2

95 = b^2

sqrt(95) = b

Answer: (-4,22)

I got this by solving the equation on a graph.

Answer:

B. y= -2x+3

Step-by-step explanation:

1) the slope-interception form is: y=s*x+i, where s - slope, i - interception are unknown numbers;

2) if y(0)=3, then i=3, it means the equation is y=s*x+3;

3) if to substitute x=1; y=1 into the equation y=s*x+3, then s= -2. It means, the initial equation is y= -2x+3.

4) finally, the correct answer is B.

Answer:

I think that the remainder would be 39. I am not 100% sure however.

Step-by-step explanation:

I started by doing 8411-5200 because 100 groups of 52 is 5200. I got 3211 and then divided that by 52. I got 62 r 39. Hope this helps!!

Step-by-step explanation:

Volume of cuboid = Length x breadth x height

= 5 x 3 x 4

= 60m^3

Volume of cylinder = πr^2h

= 22/7 x 2^2x5

= 63.36m^3

Answer:

[tex]\frac{24}{35}[/tex]

Step-by-step explanation:

[tex]\frac{4}{5}[/tex] × [tex]\frac{6}{7}[/tex]

= [tex]\frac{4(6)}{5(7)}[/tex]

= [tex]\frac{24}{35}[/tex]

to divide by a fraction, you multiply by the reciprocal which just means reversing the fraction. so 8/ 1/3 is the same as 8 x 3.

9n-14=5n+58

9n-5n=58+14

4n=72 / 4

n=18

Hello! (:

9n-14=5n+58

Move all the variables to the left, using the opposite operation:

9n-5n=58+14

9n-5n=72

4n=72

Divide both sides by 4 to isolate n:

n=18

Answer:

28meters and 112meters

Step-by-step explanation:

one piece is x

the other is 4x

therefore; 4x+x=140

5x= 140

divide both sides by 5

x=28

4x=4(28)

=112

Answer:

  (0, 1)

Step-by-step explanation:

The orthocenter is the point of intersection of the altitudes of the triangle. Each altitude is a line through a vertex and perpendicular to the opposite side.

In the attached, we labeled the points A, B, C in the order given. Side BC of the triangle is vertical, so the horizontal line through A will have equation ...

  y = 1

The line AC can be seen on the graph to have slope -1, so the altitude through point B will have slope 1. Its equation will be ...

  y = x+1

Then the point of intersection will be where ...

  y = y

  1 = x+1

  0 = x

That is, the orthocenter is the point (x, y) = (0, 1).

Answer:

-2 and 8.

Step-by-step explanation:

Isolate the m variable.

3m<4m+5

Subtract 4m from both sides.

-m<5

Divide both sides by -1.

m>-5

Solutions to this inequality are any number greater than -5 which is -2 and 8.
