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]

Step 2

Add the 2 x 1 matrices on LHS, we get

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

Step 3,

we get

-4x_1 + x_2 + 11 = -11

and

5x_1 + 4x_2-19=40

Step 4,

Simplify, we get

-4x_1+x_2=-22----(1)\\ 5x_1+4x_2=59----(2)

Step 5,

multiply eqn(1) by 4

we get

16x_1+4x_2=-88

Step 6,

eqn (2) - eqn(3)

we get

21x_1 = 147\\x_1 =\frac{147}{21} \\x_1= 7

substituting in eqn (1), we get

(-4 \times 7) + x_2 = -22

so, we get

x_2 = 6

Therefore

x_1 = 7\\x_2 = 6
