Answer:

J = 7.5

Step-by-step explanation:

* This is going off of the estimate that the = sign means the equation is = to 0, as there is no value after the equal sign. *

First, start off by adding all of the like numbers.

11 + (-3) + 7 = 8 + 7 = 15

- 1/8 j - 3/8 j  = - 4/8 j.

Combining those two sums, we get:

15 - 4/8 j = 0

Subtract 15 from both sides,

-4/8 j = -15

Simplify -4/8 to -1/2, and then to -0.5

-0.5j = -15

Divide.

-15/-0.5 = 7.5

When you divide a negative number by another negative number, you get a positive. Therefore, the answer is J = 7.5

If the number after the = sign IS NOT 0, then when you get to 15 - 0.5j, just do the steps but with a number that isn't 0.

5/2c-3=3/7c+4 and please explain
Naddika [18.5K]
5/2c - 3 = 3/7c + 4...subtract 3/7c from both sides
5/2c - 3/7c - 3 = 4.....add 3 to both sides
5/2c - 3/7c = 4 + 3....common denominator of 7 and 2 is 14
35/14c - 6/14c = 7...simplify
29/14c = 7....multiply both sides by 14/29, eliminating the 29/14 on left
c = 7 * 14/29
c = 98/29 = 3 11/29

Given that B is the midpoint of segment AC, find the unknown values.
shusha [124]
Hi! for x, you need to do 2x-8 = x+17 and solve, because since b is the midpoint, ab and bc would be congruent.

2x-8 = x+17
1x-8 = 17
1x = 25
x = 25

in order to find ab, you plug in the x into the expression.

ab = 2x-8
ab = 2(25)-8
ab = 42

do the same for bc:

bc = x + 17
bc = 25 + 17
bc = 42

and for ac, combine the two expressions and plug in the value for x.

ac = ab + bc
ac = 2x-8 + x+17
ac = 2(25)-8 + 25+17
ac = 84

i hope this helped! have a good day/night :)

Write an equation for the line of fit for this data in the form y=mx+b where x is latitude and y is temperature.
notka56 [123]

Answer:

y = -x + 115

Step-by-step explanation:

Given

See attachment for graph

Required

The equation of best fit

First, we pick two corresponding points on the graph,

We have:

(x_1,y_1) =(55,60)

(x_2,y_2) =(45,70)

Calculate slope (m)

m = \frac{y_2 -y_1}{x_2 - x_1}

This gives:

m = \frac{70 - 60}{45 - 55}

m = \frac{10}{-10}

m = -1

The equation is the calculated using:

y = m(x - x_1) + y_1

This gives

y = -1(x - 55) + 60

Open bracket

y = -x + 55 + 60

y = -x + 115

The ordered pair (3,6) is the solution of the system of equations represented by which lines<br>​
Temka [501]

Answer:

p and n

Step-by-step explanation:

The solution to a system of equations given graphically is at the point of intersection of the 2 lines.

The lines p and n intersect at (3, 6)

Thus (3, 6) is the solution to the system of equations represented by p and n
