Greetings!

Solve for x.
45(15x+20)-7x=56(12x-24)+6
Distribute the Parenthesis.
675x+900-7x=56(12x-24)+6
675x+900-7x=672x-1344+6
Combine Like Terms.
668x+900=672x-1338
Add 1338 to both sides.
(668x+900)+1338=(672x-1338)+1338
Subtract 668x from both sides.
[(668x+900)+1338]-668x=[(672x-1338)+1338]-668x
Simplify.
900+1338=672x-668x
2238=4x
Divide both sides by 4.
(2238)/4=(4x)/4
Simplify.
559.5=x
x=559.5

Hope this helps.

Use the discriminant to determine all values of k which would result in the graph of
Shalnov [3]

Answer:

k > 100

Step-by-step explanation:

y= x²+20x+k

if the graph doesn't intersect the x-axis it means it has no real roots so the discriminat has to be negative so will have imaginary roots

discriminant is

b²-4ac = 20²-4*1*k = 400-4k for this to be negative k has to be more then 100 so will have 400 - a number bigger then 400

k > 100 is the solution

Question 5 (1 point)
Airida [17]

Answer:

y = 90

Step-by-step explanation:

If y varies jointly as x and z, then;

y = kxz

If y = 18 when x = 2 and z = 3

18 = k(2)(3)

18 = 6k

k = 18/6

k = 3

To get y when x = 5 and z = 6

y = kxz

y = 3(5)(6)

y = 15*6

y = 90

Hence the value of y is 90
