Simplify each term.
4x^2 - 5x^2 + 3x - 1/x -2 2
Hope this helps! :)

By the remainder theorem this will be
f(2) = 4(2)^3 - 5(2)^2 + 3(2) - 1
= 32 - 20 + 6 - 1
= 12 + 5

= 17

Can some one help me graph y=4x + 5 I keep doing something wrong.

Delvig [45]

Answer:

y = - 3x + 4

Step-by-step explanation:

Line is passing through the points (1, 1) & (0, 4)

Slope of line = (4-1)/(0-1) = 3/(-1) = - 3

Equation of line

y = mx + b

Here m = - 3, b = 4

y = - 3x + 4

Using point (1, 1)

y - 1= - 3(x - 1)

y = - 3x +3 +1

y = - 3x + 4

If d , e, and f are midpoints of the sides of ABC, find the perimeter of ABC.

ehidna [41]

Answer:

Perimeter of the ΔDEF = 10.6 cm

Step-by-step explanation:

The given question is incomplete; here is the complete question with attachment enclosed with the answer.

D, E, and F are the midpoints of the sides AB, BC, and CA respectively. If AB = 8 cm, BC = 7.2 cm and AC = 6 cm, then find the perimeter of ΔDEF.

By the midpoint theorem of the triangle,

Since D, E, F are the midpoints of the sides AB, BC and CA respectively.

Therefore, DF ║ BC and $FD=\frac{1}{2}\times(BC)$

FD = $\frac{7.2}{2}$

= 3.6

Similarly, $FE=\frac{1}{2}\times(AB)$

$FE=\frac{8}{2}$

FE = 4 cm

And $DE=\frac{AC}{2}$

DE = $\frac{6}{2}$

= 3 cm

Now perimeter of ΔDEF = DE + EF + FD

= 3 + 4+ 3.6

= 10.6 cm

Perimeter of the ΔDEF is 10.6 cm.
