the answer is 23x +4

you can't combine them anymore since they are not like terms

13x-8+7x+4+3x
Combine like terms
23x-4
It can only be simplified. Without an equal sign (=), x cannot be found.

Find the area of a triangle if the base is 8.2m and the height is 4.6m.

Dmitry [639]

In order to find an area of a triangle we have to multiply the base by the height.

8.2*4.6=?

So now all we have to do is multiply to find our answer of 37.72!

Find a polynomial function with leading coefficient 1 that has the given zeros, multiplicities, and degree. zero: 1, multiplicit

vfiekz [6]

Polynomial expression for the given conditions is formulated in the equation

y(x)=1*(x-2)^3(x-0)^2

The polynomial for the conditions with leading coefficient 1 that has the given zeros, multiplicities, and degree. Zero: 2, multiplicity: 3 Zero: 0, multiplicity: 2 Degree: 5 is given as

According to the given condition

The given conditions to write the polynomial equations are as follows

Zero 2 and Multiplicity 3

Zero 0 and Multiplicity 2

Degree of polynomial expression = 5

The leading coefficient of polynomial expression = 1

Let us consider the polynomial equation has only one variable and hence in the general form we can write the equation of polynomial as follows

From the general form of polynomial expression as shown in equation (1) we can write

Polynomial expression for the given conditions is formulated in the equation

y(x)=1*(x-2)^3(x)^2-------(2)

So the polynomial for the conditions given in the question is expressed as

y(x)=1*(x-2)^3(x)^2

For the given line segment, write the equation of the perpendicular bisector.

natta225 [31]

Answer:

$y=-0.8x-4.7$

Step-by-step explanation:

Let

$A(-6,-4), B(-2,1)$

we know that

The perpendicular bisector pass through the midpoint of AB

step 1

Find the midpoint AB

$M=((-6-2)/2,(-4+1)/2)$

$M=(-4,-1.5)$

step 2

Find the slope of the given line AB

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute

$m=\frac{1+4}{-2+6}$

$m=\frac{5}{4}$

step 3

Find the slope of the perpendicular bisector

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

$m1*m2=-1$

we have

$m1=\frac{5}{4}$ ----> slope of the given line

substitute in the formula

$\frac{5}{4}*m2=-1$

$m2=-\frac{4}{5}=-0.8$

step 4

Find the equation of the perpendicular bisector

we know that

The equation of the line into point slope form is equal to

$y-y1=m(x-x1)$

we have

$m=-0.8$

$M=(-4,-1.5)$

substitute

$y+1.5=-0.8(x+4)$

$y=-0.8x-3.2-1.5$

$y=-0.8x-4.7$
