Answer:

y = -.075x +4.89

Step-by-step explanation:

The data set has almost no net slope, so the first equation is the most appropriate. (An absolute value function would be a much better fit.)

y = -.075x +4.89

P and Q are points on the line y= 2 -4x complete the coordinates of P and Q, P(0, ) Q( ,0)

docker41 [41]

(d): y=2-4x
P(0;y) belongs to (d)
=> y=2-4*0
= 2
So P(0;2)
Q(x;0) belongs to (d)
=> 0=2-4*x
<=> x=1/2
So Q(1/2;0)

If mJK=(7x-39) and mML)=87, find x

lilavasa [31]

If two chords of a circle are congruent, then their intercepted arcs are congruent
7x-39 = 87
7x = 87 + 39
7x = 126
x = 126/7
x = 18

Which of the following have the correct solution? Check all

Neko [114]

Step-by-step explanation:

To do this, we will substitute the x values to their corresponding equations,

$2x + 5 \\ = 2(7) + 5 \\ = 14 + 5 \\ = 19$

Given 2x + 15 = 19

Calculated 2x + 15 = 19

Given = Calculated, this solution is correct.

$3 + x + 2 -x \\ = 3 + 3 + 2 - 3 \\ = 8 - 3 \\ = 5$

Given 3 + x + 2 - x = 16

Calculated 3 + x + 2 - x = 5

Given not equal to calculated, this solution is incorrect.

$\frac{x + 2}{5} \\ = \frac{8 + 2}{5} \\ = \frac{10}{5} \\ = 2$

Given (x+2)/5 = 2

Calculated (x+2)/5 = 2

Given = Calculated, this solution is correct.

$6 = 2x - 8 \\ 2x - 8 = 6$

$2x - 8 \\ = 2(7) - 8 \\ = 14 - 8 \\ = 6$

Given 2x - 8 = 6

Calculated 2x - 8 = 6

Given = Calculated, this solution is correct.

$14 = \frac{1}{3} x + 5 \\ \frac{1}{3} x + 5 = 14$

$\frac{1}{3} x + 5 \\ = \frac{1}{3}(18) + 5 \\ = \frac{18}{3} + 5 \\ = 6 + 5 \\ = 11$

Given 1/3x + 5 = 14

Calculated 1/3x + 5 = 11

Given not equal to Calculated, this solution is not correct.

Therefore the Correct solutions are 1,3 and 4.
