Step-by-step explanation:
Answer:
x=-7/3, 7/3.
Step-by-step explanation:
0=9x^2-49
9x^2-49=0
factor
(3x+7)(3x-7)=0
3x+7=0, 3x-7=0
3x=0-7, 3x=-7, x=-7/3

9 (x− 3 =) 45 pleas answer fast
Answer: x = 8
Step-by-step explanation:
9 ( x - 3 ) = 45
distribute 9
9x - 27 = 45
combine constants
9x = 45 + 27
compute 45 + 27
9x = 72
divide both by 9
9x/9 = 72/9
final answer
x = 8

MODELING REAL LIFE The table shows the amount y (in fluid Ounces) of carpet cleaner in a tank after x minutes of cleaning.
X
у
5 108
10 88
15 68
a. Write an equation that represents the amount of cleaner in the tank after x minutes.
y = - Ix + 128
b. How much cleaner is in the tank when the cleaning begins?
There are
fluid Ounces of cleaner in the tank.
C. After how many minutes is the tank empty?
The tank will be empty in 32 minutes.
What is the point-slope form of a line?If m is the slope of the line that passes through the point (x₁, y₁), then the equation of the line is y - y₁ = m (x - x₁).
(a)
The table of values is given.
Rewrite the table of values as ordered pairs:
(5,108), (10,88), (15,68)
Since the difference between any two consecutive y values and the difference between any two consecutive x values is constant, the data shows a linear relation.
The slope of the line that passes through (5,108) and (10,88) is:
m = (88-108)/(10-5)
m = -4
The equation of the line with slope m = -4 and passes through (5,108) is:
y - 108 = -4(x - 5)
y = -4x + 20 + 108
y = -4x + 128 (1)
(b)
Substitute x = 0into equation (1):
y = - 4(0) + 128
y = 128
The tank is 128 ounces cleaner at the beginning.
(c)
Substitute y = 0 into equation (1):
0 = -4x + 128
4x = 128
x = 32
Therefore, the tank will be empty in 32 minutes.

Complete the equation.
(4x)−2(4x)3(4x)9=(4x)
Given:
Consider the given equation is
[tex](4x)^{-2}(4x)^3(4x)^9=(4x)^?[/tex]
To find:
The missing value in the given equation and complete the equation.
Solution:
We have,
[tex](4x)^{-2}(4x)^3(4x)^9=(4x)^?[/tex]
Taking LHS, we get
[tex]LHS=(4x)^{-2}(4x)^3(4x)^9[/tex]
[tex]LHS=(4x)^{-2+3+9}[/tex] [tex][\because a^ma^n=a^{m+n}][/tex]
[tex]LHS=(4x)^{10}[/tex]
and,
[tex]RHS=(4x)^?[/tex]
Let the missing value be k.
For each equation LHS=RHS.
[tex](4x)^{10}=(4x)^{k}[/tex]
[tex]10=k[/tex]
Therefore, the missing value is 10 and the complete equation is [tex](4x)^{-2}(4x)^3(4x)^9=(4x)^{10}[/tex].

56 is 28% of an unknown number is (x)
Answer:
Change 28% to a decimal by moving the decimal point 2 places to the left:
28% = 0.28
Write the question as an equation to get:
56 = 0.28x
Now to solve for x, divide both sides by 0.28:
x = 56 / 0.28
x = 200
The unknown number is 200.
Step-by-step explanation:
Step-by-step explanation:
28% of an unknown number is (x)=56
28/100 of x=56

MK is the segment bisector of RS Find the length of RS.
The length of RS is?
Answer:
m(RS) = 34
Step-by-step explanation:
Since, MK is the segment bisector of RS.
Therefore, segment MK will bisect RS in two equal segments RM and MS.
RM ≅ MS
m(RM) = m(SM) = 17
m(RM) + m(SM) = m(RS)
m(RS) = 17 + 17
m(RS) = 34
