Horizontal line has zero slope
slope=rise/run=0
#1) and #2) both are slope=0
greatest y value is +4 from x=3 to 4.
then least y value is -3 from x=-4 to -3.

Answer:

See below

Step-by-step explanation:

The first two questions are slope = 0

a horizontal line has zero slope

slope = rise/run = 0 / run = 0

Greatest y value is + 4 from x = 3 to 4

the least y value is -3 fro x = -4 to -3

The mass of Venus is 4.87 × 1024 kilograms, and the mass of Jupiter is 1,898 × 1024 kilograms.

aivan3 [116]

ASSUMPTION = 10 TO THE POWER OF 24

Venus = 4.87 x 10^24

Jupiter = 1898 x 10^24
= 1.898 x 10^27

(1.898 x 10^27) / (4.87 x 10^24)
= 389.7330595
=390 (3 s.f)

Find x1 and x2.

stepladder [879]

Answer:

$x_1 = 7\\x_2 = 6$

Step-by-step explanation:

To find x₁ and x₂ :

$\left[\begin{array}{ccc}-4&1\\5&4\\\end{array}\right] \times \left[\begin{array}{ccc}x_1\\x_2\\\end{array}\right] + \left[\begin{array}{ccc}11\\-19\\\end{array}\right] = \left[\begin{array}{ccc}-11\\40\\\end{array}\right]$

Step 1

Multiply first 2 x 2 matrix with 2 x 1 vector, we get

$\left[\begin{array}{ccc}-4x_1&+ x_2\\5x_1&+ 4x_2\\\end{array}\right] + \left[\begin{array}{ccc}11\\-19\\\end{array}\right] = \left[\begin{array}{ccc}-11\\40\end{array}\right]$
