Answer:
x = -5
Step-by-step explanation:
To find the equation of a line, use the formula y = mx + b, where m is the slope of the line and b is the y intercept.
To find the slope, use your ordered pairs: m = (y2 - y1)/(x2 - x1). Substituting in your values, m = (8-6)/(-5 - -5), or m = 2/0. Since you cannot divide by 0, the slope is undefined; you have a vertical line.
If you plot the points on a graph, (-5, 6) and (-5, 8) both pass through -5 on the x axis. Since this is a vertical line, it will never cross the y axis, so you will not have a y intercept.
Your equation is x = -5.
The line equation for its slope and one point is:
y - y1 = m(x - x1)
m is the slope, x1, y1 are the point coordinates, so lets substitute:
y - 4 = (1/2)(x - 2)
y = <span>(1/2)x + 3</span>
Answer:
Not sure what they want when they say evaluate it but the answer would be -12.
Step-by-step explanation:
You distribute the 6, so you would multiply 6 x 7 then keep the minus sign and multiply 6 x 9. So you would have 42 - 54, and just subtract which = -12
The Simplification of the following expression is;
- m = -30/7
- v = -8.8
- x = 3
- u = -2.49
- a = -3/70
<h3>Simplification</h3>
7/8m - 4/7 - 5/6m = - 3/4
7/8m - 5/6m = -3/4 + 4/7
21m-20m/24 = -21+16/28
1/24m = -5/28
m = -5/28 ÷ 1/24
= -5/28 × 24/1
= -120/28
m = -30/7
4.3v + 10.75 - 4v = 8.11
0.3v = 8.11 - 10.75
0.3v = -2.64
v = -2.64/0.3
v = -8.8
9/7 + 9/7x - 6/7x =0
9/7x - 6/7x = - 9/7
(9-6)x /7 = 9/7
3/7x = 9/7
x = 9/7 ÷ 3/7
= 9/7 × 7/3
= 9/3
x = 3
6.9u - 2 - 3.2u - 10 = 2.8
3.7u = 2.8 - 12
3.7u = -9.2
u = -9.2/3.7
u = -2.49
8/5 = - 4a + 7/5 - 2/3a
8/5 - 7/5 = -4a - 2/3a
8-7/5 = -12a-2a/3
1/5 = -14/3a
a = 1/5 ÷ -14/3
= 1/5 × -3/14
a = -3/70

Strictly speacking, since 'c' is defined in the statement this shoudl work:
Part 1) According to the exercise, the letter 'c' represents the total cost of the three pounds of oranges. So c is the total cost of the three pounds of oranges.
Part 2) Rami has three pounds of oranges. In order to know how much a pound of oranges cost, he will have to divide by 3 the total cost of the three pounds 'c'
Part 3) The cost per pound is:
cost 1 pound of oranges = c/3
