8x-4=2(4x-4) math question I need the answer to pls help
Answer:
no solutions.
8x-4=2(4x-4)
distribute.
8x-4 = 2*4x+2*-4
8x-4=8x-8
add 4 to both sides
8x= 8x - 4
subtract 8x from both sides
0=-4
this has no solutions, since 0 is not equal to -4.

Write the equation of a line in slope-intercept form, y = mx + b, between the following
points: (2, 5) and (-4,-4).
Answer:
[tex]y = \frac{3}{2} x + 2[/tex]
Step-by-step explanation:
In the slope-intercept form y= mx +b, m is the slope and b is the y- intercept.
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} } [/tex]
Using the formula above,
[tex]slope = \frac{5 - ( - 4)}{2 - ( - 4)} [/tex]
[tex]m = \frac{5 + 4}{2 + 4} [/tex]
[tex]m = \frac{9}{6} [/tex]
[tex]m = \frac{3}{2} [/tex]
Substitute the value of m into the equation:
[tex]y = \frac{3}{2} x + b[/tex]
To find the value of b, substitute a pair of coordinates into the equation.
When x= 2, y= 5,
[tex]5 = \frac{3}{2} (2) + b[/tex]
5= 3 +b
b= 5 -3
b= 2
Thus, the equation of the line is [tex]y = \frac{3}{2} x + 2[/tex].
The ratio of the amount of money Karen had to the amount of money Peter had was 2 : 5. After Peter received $75 from his mother, the ratio of the amount of money Karen had to the amount of money Peter had became 4 : 15. How much money did each person have at first?
Answer:
$60 and $150
Step-by-step explanation:
Initially
Karen : Peter = 2 : 5
After Peter receiving $75 the ratio is
4 : 15
We can suppose that initally the amount of monye Karen has is 2x and Peter is 5x.
The new ratio is
2x : (5x +75) = 4 :15
2x (15)= 4 (5x +75)
30 x = 20 x + 300
10 x = 300
x = 30
So at first Karen has 2x =60 dollars while Peter has 5x = 5(3) = 150 dollars.

Answer:
Step-by-step explanation:
a) Age of Jeff = j
Tina's age = j - 4
b) j = 15 years
Tina's age = 15 - 4 = 11 years
j = 20 years
Tina's age = 20 - 4 = 16 years
j = 58 years
Tina's age = 58 - 4 = 54 years

temperature dropped 48º.
How many degrees did the
temperature drop each hour?
Answer:
4 degrees every hour
Step-by-step explanation:
Since it was 48 degrees over a total of 12 hours we can do:
48 / 12 = 4 degrees.
It may be presented as -4 degrees since it is dropping in tempature therefore making it negative.
