The lengths of the sides of a triangle are 3, 3, . Can the triangle be a right triangle?

Answer:

f(-8) = -18

Step-by-step explanation:

given :

f(x) = 2(x – 3) + 4

to find f(-8), simply substitute x= -8 into the function:

f(x) = 2(x – 3) + 4

f(-8) = 2[(-8) – 3] + 4

= 2[-8 – 3] + 4

= 2[-11] + 4

= -22+4

= -18

Given:

Endpoints of a segment are J(−24,−4) and K(−4,6).

To find:

The equation in point-slope form for the perpendicular bisector of JK.

Solution:

Slope of JK is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{6-(-4)}{-4-(-24)}[/tex]

[tex]m=\dfrac{6+4}{-4+24}[/tex]

[tex]m=\dfrac{10}{20}[/tex]

[tex]m=\dfrac{1}{2}[/tex]

Product of slopes of two perpendicular lines is -1. So, product of perpendicular line of JK is -2.

Perpendicular bisector of JK passes through the midpoint of JK.

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-24-4}{2},\dfrac{-4+6}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-28}{2},\dfrac{2}{2}\right)[/tex]

[tex]Midpoint=\left(-14,1\right)[/tex]

Point slope form:

[tex]y-y_1=m(x-x_1)[/tex]

where, m is slope.

Perpendicular bisector of JK passes through (-14,1) with slope -2. So, the point slope form of JK is

[tex]y-1=-2(x-(-14))[/tex]

[tex]y-1=-2(x+14)[/tex]

Therefore, the correct option is D.

Answer:

draw a line trough (2,3) and (0, 2)

Step-by-step explanation:

f(x)=(3/2)x+2

so 3/2 is your slope  and 2 is your y coordinate of y-intercept

pick any point to start for example (0, 0) and go slope=rise/run=3/2 and you will end-up at (2,3)

now you have a point (2,3) and a second the y-intercept (0,2)

draw a line trough those points

Answer:

2.31 ×10 ^− 2

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  

10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:

Winston:$32,000

Fran:$48,000

1 of 4 parts is equal to 1 of 6 parts so if you add 4 parts to 6 parts you get 10. Divide the total amount by 10 and you get 8000. multiply 8000 to the amount of parts each person gets and you get that.

Answer:

the standard form equation is 1/2x^2-x-3/2=0

the vertex form equation is  1/2(x-1)^2-2=0

Step-by-step explanation:

Unfortunately, this can't be written in slope intercept form but I can write it in standard form(ax^2+bx+c) or vertex form (a(x-h)+k)

The vertex is (1,-2)

I estimate a=1/2 because the graph was widened and that can only be done by a fraction.

So, 1/2(x-1)^2-2=0

To find it in standard form

foil (x-1)(x-1)= x^2-2x+1

Then multiply by 1/2(x^2-2x+1)= 1/2x^2-x+1/2-2

To add 1/2-2. You mulitply -2 by 2/2 which equals 1/2-4/2 which equals -3/2

So the standard form equation is 1/2x^2-x-3/2=0

Answer:

7xy + 2x^2t

Step by step explanation:

You just group the like terms and simplify (pay attention to the signs)

5xy + 2xy = 7xy

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

So the answer is : 7xy + 2x^2t

Step-by-step explanation:

= 33/100×171

=56.43

Answer:

Yes, it is a solution

Step-by-step explanation:

(x,y) (1,-3)

a. Plug in x:

y= 1-4

y = -3 yes this is correct as -3 is on y.

b. Plug in X.

y=9(1)-12

y=9-12

y=-3 yes this is also correct as this also is -3 for y.
