Answer:

The area of the given triangle is 6 sq units.

Step-by-step explanation:

The area of triangle is given by

Area =

$\frac{1}{2} \times base \times height$

Here base is 6units and height is 2units

hence area= (6*2)/2= 6 units

x= -0.25 and 1.25

x = -0.5 and 1.5

x = 0 and 1

x = -0.375 and 1.625

Step-by-step explanation:

Given equation of the curve is

$y = 4x^2 -4x-1$

(i)

First equation $4x^2 -4x-1 =0$

Here y = 0

In x-axis the value of y = 0

The graph cuts the x-axis at(-0.25,0) and (1.25,0)

So, x= -0.25 and 1.25

(ii)

$4x^2 -4x-1 =2$

here y = 2

The line y= 2 cuts the curve at (-0.5,2) and (1.5,2)

So, x = -0.5 and 1.5

Given equation of the curve is

$y= 3x^2-3x -1$

(i)

$3x^2-3x +2 =2$

$\Leftrightarrow 3x^2-3x -1 = -1$

Here y = -1

The line y = -1 cuts the curve at (0,-1) and (1,-1)

So x = 0 and 1

(ii)

$3x^2-3x -1 =x+1$

Here y = x+1

The line y -x =1 cuts the curve at (-0.375,0.5) and (1.625,2).

So x = -0.375 and 1.625

What is the slope of the line whose equation is 2y = 5x + 4? 1) 5 2) 2 3) 5/2 4) 2/5

Romashka [77]

Answer:

3) 5/2

Step-by-step explanation:

2y = 5x + 4

y = 5/2x + 2

slope = 5/2

(y = mx + b, m being slope, b being y intercept)

6. Check whether - 150 is a term of the AP: 11, 8,5,2...

AURORKA [14]

To check -150 is present in the sequence
-150=a+(n-1)d
According to the given series
a=11,d=-3
So we need to find n
If n is a fraction then it does not belongs to that series
From formula=-150=11+(n-1)-3
-150=11-3n+3
-150=14-3n
-150-14=-3n
-164=-3n
n=164/3
We got n as a fraction so -150 does not belong to series
