Okay so it's basically saying that 30 is greater than 3x by 89
We would represent that mathematically by:
30 - 89 = 3x
So then we just solve this like we usually would
30 - 89 = -59
-59 [tex]\div[/tex] 3 = 19.666. . .

Find the slope of the line passing through the points (5, 1) and (5, "-6)"
Answer: undefined
This is because the x value is 5, which means that there is no horizontal movement of the line. So therefore, the line is vertical. And vertical lines have an undefined slope.
Hope this helps!
Answer:
the slope is just x= 5
Step-by-step explanation:
because if its just going streight down it would just be a line on x axis on 5
Which statement explains how to correct the error that was made?
O The subtraction property of equality should have been applied to move m to the other side of the equation.
O The multiplication property of equality should have been applied in the last step.
The division property of equality should have been used to divide by k instead of m.
O The square root property should have been applied to both complete sides of the equation instead of to select
variables.
Solving for v in the given equation is performed by making v the equation's
subject.
Response:The statement that describes where the error was made is option;
The square root property should have been applied to both complete sides of the equation instead of to select variables.Method for solving for v in the given equation;v can be solved for from the given expression as follows;
[tex]\displaystyle k = \mathbf{\frac{1}{2} \cdot m \cdot v^2}[/tex]
[tex]\displaystyle k \div m = \mathbf{\left(\frac{1}{2} \cdot m \cdot v^2 \right) \div m}[/tex]
[tex]\displaystyle \frac{k}{m} \times 2 = \left( \frac{1}{2} \cdot v^2 \right) \times 2[/tex]
[tex]\displaystyle \frac{2 \cdot k}{m}= \mathbf{v^2}[/tex]
Taking the square root of both sides of the equation gives;
[tex]\pm \sqrt{\displaystyle \frac{2 \cdot k}{m}} = \mathbf{\sqrt{v^2}}[/tex]
Therefore;
[tex]\displaystyle \pm \sqrt{\frac{2 \cdot k}{m} } = v[/tex]
Therefore, the error was made in the step, [tex]\displaystyle \pm \frac{2 \cdot \sqrt{k} }{m} = \sqrt{v^2}[/tex] , which is by
applying the square root property was applied to only some of the
variables on the left hand side of the equation, rather than the combined
expression on the left hand side of the equation.

find f(9) if f(x) = 4^x + 12
Answer:
I think its 262156
Step-by-step explanation:
Answer:
If f(x) = 4ˣ + 12, f(9) = 262156.
Step-by-step explanation:
f(x) = 4ˣ + 12
Substitute input x = 9.
f(9) = 4⁹ + 12
Evaluate 4 to the 9th power.
f(9) = 262144 + 12
Add 262144 and 12.
f(9) = 262156.
A fast-food restaurant was selling 7 boxes of chicken nuggets for $25.90. A competing restaurant was selling 3 boxes of chicken fingers for $11.07. Which food has a higher unit price? Answer:
Answer:
The competing company is better
7 for 25.90 vs. 7 for 25.83
Step-by-step explanation:
Since it's 3 for 11.07
we need to see how much higher the price will get at 7, so divde 11.07 by 3 then double the price.
3.69 per box for competing company
11.07*2 = 22.14
22.14 + 3.69= 25.83

Step-by-step explanation:
Nayeli is driving on a long road trip. She currently has 14 gallons of gas in her car. Each hour that she drives, her car uses up 1.5 gallons of gas. How much gas would be in the tank after driving for 4 hours? How much gas would be left after t hours?
Answer:
8 gallons
Step-by-step explanation:
Total gas in the car = 14 gallons
Each hour gas usage = 1.5 gallons
Total hours traveled = 4 hours
Left gas after 4 hours
= 14-1.5(4)
=14-6
=8 gallons
Left gas after t hours
=14-1.5t
Hence the answer is after 4 hours, 8 gallons are left after t hour(s) 14-1.5t
The amount of gas in the tank after driving for 4 hours will be 6 gallons. The amount of gas that is left after t hours will be 14 - 1.5t.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Nayeli is driving on a long road trip. She currently has 14 gallons of gas in her car. Each hour that she drives, her car uses up 1.5 gallons of gas.

Step-by-step explanation:
what do we need to do ? find the 0 solutions for x ?
if that is the case, let's just do all the multiplication first :
(3/2)² × (2/3)⁴x² = x
9/4 × 16/81 x² = x
4/9 x² = x
4/9 x² - x = 0
4x² - 9x = 0
x × (4x - 9) = 0
so, one solution is obviously x = 0.

what number is six more than 1/3 of 90? step by step I have a test tomorrow and I don't know any math
Answer:
36
Step-by-step explanation:
First, just multiply 90 by 1/3. 90 is equal to 90/1 as any number divided by 1 is still equal to itself.
[tex]\frac{90}{1}*\frac{1}{3}=\frac{90*1}{1*3}=\frac{90}{3}[/tex]
Now, 90/3 is just 90 ÷ 3.
[tex]90 \div 3 = 30[/tex]
Finally, just add 6 to it.
[tex]30+6=36[/tex]
Answer:
36
Step-by-step explanation:
1/3 of 90 is 30
6 more is 30+6=36

Step-by-step explanation:
(Total increase) = (Original Amount) × (Multiplier)²
Rearrange the equation to find the original amount
(Total increase) ÷ ( Multiplier)² = (Original amount)
To find the Multiplier, add 1 to 3% = 1.03
Substitute what you can
(72) ÷ (1.03)² = Original amount
£67.8669054576 = Original Amount
Round up the number to 2 decimal places since it is British Pounds currency
£67.87 = Original Amount

Give the slope values that are parallel and perpendicular to a slope of 1/4.
Step-by-step explanation:
Finding the Slopes of Parallel and Perpendicular Lines
How do we know if two distinct lines are parallel, perpendicular or neither? To make that determination, we need to review some background knowledge about slope.
Concept 1: When two points are given, the slope of a line can be algebraically solved using the following formula:
Slope Formula
The slope,mm, of a line passing through two arbitrary points \left( {{x_1},{y_1}} \right)(x
1
,y
1
) and \left( {{x_2},{y_2}} \right)(x
2
,y
2
) is calculated as follows…
m = (ysub2-ysub1)/(xsub2-xsub1)
Concept 2: When a linear equation is given, we can find the slope by transforming it into the Slope-Intercept Form. The value of slope will stand out, as it is the coefficient of the linear term (xx-term).
Slope-Intercept Form of a Line
The linear equation written in the form y = mx + by=mx+b is in slope-intercept form where:
m is the slope, and b is the y-intercept
Now, suppose we have two distinct and nonvertical lines, {\ell _1}ℓ
1
and {\ell _2}ℓ
2
in Slope-Intercept Form.
Line 1:
line 1 → y=msub1x+b
Line 2:
line 2 → y = msub2x+b
Parallel Lines: The lines are parallel if their slopes are equal or the same. That means
Equal Slopes:
msub1 = msub2
Graph:
graph showing line 1 and line 2 parallel on the coordinate plane.
Perpendicular Lines: The lines are perpendicular if their slopes are opposite reciprocals of each other. Or, if we multiply their slopes together, we get a product of - \,1−1. These lines intersect at a ninety-degree angle, 90°.
Opposite Reciprocal Slopes:
msub1 = -(1/msub2)
Product of Slopes:
msub1× msub2 = -1
Graph:
graph showing line 1 and line 2 perpendicular to each other on the coordinate plane.
Examples of How to Find the Slopes of Parallel and Perpendicular Lines
Example 1: Line 1 passes through the points \left( {1,3} \right)(1,3) and \left( {4,9} \right)(4,9), while line 2 passes through \left( {2,5} \right)(2,5) and \left( { - \,2, - \,3} \right)(−2,−3). Tell whether these lines are parallel, perpendicular, or neither.
