Answer:

option A

Step-by-step explanation:

the statement tell us that she slides the triangle 2 units down, so the vertical axis is the one that we are going to modify

we have the points: (1,2), (3,3) and (4,1)

so to these points we subtract "2" to the variable Y

I mean:

(1,2): 2-2=0

(3,3): 3-2=1

(4,1): 1-2=-1

finally we have:

(1,0), (3,1) and (4,-1)

Answer:

-8

Step-by-step explanation:

In order to find the answer to this question you need to use the slope formula, substitute, subtract, and simplify if needed.

$(9,5),(4,1) = (x^1,y^1), (x^2,y^2)$

$m = \frac{y^2-y^1}{x^2-x^1} = \frac{9-1}{4-5}$

$9-1=8$

$4-5=-1$

$= -8$

Hope this helps.

Which equation represents a linear function with a slope of 12 and a y-intercept of -15? A. Y=−15x+12 B. Y=−x2+15 C. Y=x2−15 D.

Naddik [55]

Answer:

y = 12x-15

Step-by-step explanation:

The equation of a line is given by :

$y=mx+c$

Where

m is slope and c is y-intecept.

Here, the slope is 12 and y-intercept is -15.

Then the equation is :

y = 12x+(-15)

y = 12x-15

Hence, the required equation for the line is "y=12x-15".

ABCD is a trapezium with AB= x cm, DC=( x+ 4 )cm and the distance between the parallel sides AB and DC is 1/2 x cm

horsena [70]

We know that the smaller base is x cm, the greater base is x+4 cm, and that the height is x/2 cm.

Since the area of a trapezium is given by

$A=\dfrac{(b+B)h}{2}$

If we plug the expressions we have

$A=\dfrac{(x+(x+4))\frac{x}{2}}{2}=\dfrac{(2x+4)x}{4}=\dfrac{2x^2+4x}{4}$

If this must equal 84, we can solve for x as follows: start with

$\dfrac{2x^2+4x}{4}=84$

Multiply both sides by 4:

$2x^2+4x=336$

Subtract 336 from both sides:

$2x^2+4x-336=0$

We can divide both sides by 2 to make computation simpler:

$x^2+2x-168=0$

Use the quadratic formula (or any mean you prefer) to solve this equation and get the solutions

$x_1=-14,\quad x_2=12$

We can't accept the negative solution, because it would imply

$AB=-14,\quad CD=-10$

and we can't have negative side lengths. So, the answer is 12.
