Y equals -2 over 5 x + 1 y-intercept

kipiarov [429]

Y = -2/5x + 1

I think your question is what is the y-intercept? It would be 1. -2/5 is the slope.

olga_2 [115]

Answer:

x^4+x³+7x²-6x+1

Step-by-step explanation:

(x²+2x+8)(x²-x+1)

distribute

x²(x²-x+1)

x^4-x³+x²

2x(x²-x+1)

2x³-2x²+2x

8(x²-x+1)

8x²-8x+1

x^4-x³+x²+2x³-2x²+2x+8x²-8x+1

combine like terms

x^4+x³+7x²-6x+1

Point S is between R and T on line segment RT. Use the given information to write an equation in terms of x.

Setler79 [48]

Answer: $\bold{a)\quad x=\dfrac{35}{3}\qquad RS=13\dfrac{1}{3}\qquad ST=7\dfrac{2}{3}}$

b) x = 12 RS = 20 ST = 40

c) x = 7 RS = 6 ST = 11

<u>Step-by-step explanation:</u>

Use the Segment Addition Postulate: RS + ST = RT

a) (2x - 10) + (x - 4) = 21

3x - 14 = 21

3x = 35

x $=\dfrac{35}{3}$

RS = 2x - 10

$=2\bigg(\dfrac{35}{3}\bigg)-10$

$=\dfrac{70}{3}-\dfrac{30}{3}$

$=\dfrac{40}{3}$

$=\large\boxed{13\dfrac{1}{3}}$

ST = RT - RS

$=21-13\dfrac{1}{3}$

$=\large\boxed{7\dfrac{2}{3}}$

Use the same formula to solve for b and c
