Answer:

y=3x-1

Step-by-step explanation:

First, we must find the slope of the equation. To do that we take two ordered pairs from the graph.

(2,5) (10,29)

The equation for slope is m=y2-y1/x2-x1

m=29-5/10-2

m=24/8

m=3

Now, we will find the variable B.

5=3(2)+b

5=6+b

-1=b

That's how we get the equation!

y=3x-1

Answer:y= 3x-1

Step-by-step explanation:

m= y2-y1/ x2-x1=

29-5/10-2=3

Now,use: y-y1= m(x-x1)

y-5=3( x-2)

y= 3x-1

Foil: (x+9)(3x-4)

QveST [7]

QUESTION 1

The given binomial is;

$(x+9)(3x-4)$

First terms are multiplied: $x\times 3x=3x^2$

Outside terms are multiplied: $x\times -4=-4x$

Inside terms are multiplied: $9\times 3x=27x$

Last terms are Multiplied: $9\times -4=-36$

This gives us;

$=3x^2-4x+27x-36$

$=3x^2+23x-36$

QUESTION 2

We want to factor

$6r^5s+4r^4s^2-8r^2s$

The HCF is $2r^2s$

We factor to get;

$2r^2s(3r^3+2r^2s-4)$

QUESTION 3;

$x^2+x-2=0$

Split the middle term;

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

Factor

$x(x+2)-1(x+2)=0$

$(x+2)(x-1)=0$

$(x+2)=0,(x-1)=0$

$x=-2,x=1$

The solutions are;

$x=-2$ and $x=1$

These are the x-intercepts of the graph of the function

$f(x)=x^2+x-2$

Answer

h = 8.12 cm

Explanation

Area of a parallelogram = b • h

We know the area is 20.3 cm^2 and that the base is 2.5cm.

Therefore 20.3 cm^2 = 2.5h

20.3/2.5 = 8.12 cm

h = 8.12 cm
