Question

Mathematics
1 answer:
Vesnalui [34]3 years ago
4 0

Answer:

width is 4

height is 20

Step-by-step explanation:

Area=½ width × height

let the width be x

height will be 6x - 4

40 = ½ × x × (6x - 4)

40 = 2/2 × 3x² - 2x

40 = 3x² - 2x

3x² - 2x - 40 = 0

3x² -12x + 10x - 40 = 0

3x(x-4) + 10(x-4) = 0

(3x + 10)(x - 4) = 0

x = -10/3 or 4

dimension cannot be negative

x is 4

6x-4= 6(4) - 4

24 - 4

20

Which equation is a point-slope form of the equation of this line (-2, 1 ) and (1, 7 )
lana [24]

The point-slope formula:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have (-2, 1) and (1, 7).

Substitute:

m=\dfrac{7-1}{1-(-2)}=\dfrac{6}{3}=2

y-1=2(x-(-2))\\\\y-1=2(x+2)

Please help me it dues in 30 minutes​
Anna71 [15]

Answer:

y=-1/4x+2

Step-by-step explanation:

Slope intercept form is :

y=mx+b

where m is the slope, and b is the y intercept.

We are given the slope, it is -1/4. We are also given the y intercept, it is (0,2). For this form, the 0 in (0,2) is ignored, and we consider the y intercept to be 2.

So, m is -1/4, and b is 2. Substitute the values into the equation above.

y= -1/4x+2

So, the equation in slope intercept form is

y= -1/4x+2
