Answer:
if [tex]-192[/tex] is not divided by [tex]-4[/tex], then y - intercept becomes [tex]-192[/tex].
In such a situation, Shari thought that -192 was the y-intercept.
Step-by-step explanation:
Given: [tex]288x-4y=-192[/tex]
Solution:
Consider the equation:
[tex]288x-4y=-192[/tex]
To find y-intercept, put [tex]x=0[/tex]
[tex]288(0)-4y=-192\\-4y=-192\\y=\frac{-192}{-4}\\y=48[/tex]
In the second step [tex]-4y=-192[/tex],
if [tex]-192[/tex] is not divided by [tex]-4[/tex], then y - intercept becomes [tex]-192[/tex].
In such a situation, Shari thought that -192 was the y-intercept.
8. What, besides temperature, can make ocean water significantly denser?
pollutants
oxygen
salinity
pressure
Answer:
The answer is salinity because when the higher it is, the more it increases the density.
Beside temperature, salinity can make ocean water significantly denser.
What is temperature?"Temperature is a physical quantity that expresses hot and cold or a measure of the average kinetic energy of the atoms or molecules in the system."
What is salinity?"Salinity is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity)."
What is ocean water?"Seawater is a complex mixture of 96.5 percent water, 2.5 percent salts, and smaller amounts of other substances, including dissolved inorganic and organic materials, particulates, and a few atmospheric gases."
Salinity and density of water are directly proportional.Higher the salinity, higher the density.Salinity affects the movement of the ocean water current.
Hence, salinity make the ocean water significantly denser.

what is the measure of an angle if it is 90 less than 5 times its own compliment
Answer:
The angle is 30. It's complement is 60.
Step-by-step explanation:
Complementary angles add up to 90.
x + (5x-90) = 90
6x = 180
x = 30
The measure of the angle is 60 degrees.
How to find the angle?Let's denote the angle as "x." The complement of angle x would be 90 degrees minus x.
According to the given information, the angle is 90 less than 5 times its own complement. Mathematically, we can express this as:
x = 5(90 - x) - 90
Now, let's solve this equation to find the value of x:
x = 450 - 5x - 90
x + 5x = 450 - 90
6x = 360
x = 360/6
x = 60
That is the angle.

2(a+7) - 7 = 9 what is the answer
Answer:
The answer is 1
Step-by-step explanation:
2(a+7)−7=9
Step 1: Simplify both sides of the equation.
2(a+7)−7=9
(2)(a)+(2)(7)+−7=9(Distribute)
2a+14+−7=9
(2a)+(14+−7)=9(Combine Like Terms)
2a+7=9
2a+7=9
Step 2: Subtract 7 from both sides.
2a+7−7=9−7
2a=2

the ratio of the length to the width of a rectangle is 10:6. if the perimeter of the rectangle is 160 meters, find the measure of the width.
Given:
The ratio of the length to the width of a rectangle is 10:6.
Perimeter = 160 meters
To find:
The measure of the width.
Solution:
Let the length and width of the rectangle be 10x and 6x respectively.
Perimeter of a rectangle is
[tex]P=2(l+w)[/tex]
where, l is length and w is width.
Putting P=160, l=10x and w=6x, we get
[tex]160=2(10x+6x)[/tex]
[tex]160=2(16x)[/tex]
[tex]160=32x[/tex]
Divide both sides by 32.
[tex]\dfrac{160}{32}=x[/tex]
[tex]5=x[/tex]
Now,
[tex]Width=6x[/tex]
[tex]Width=6(5)[/tex]
[tex]Width=30[/tex]
Therefore, the width of the rectangle is 30 meters.

Answer:
Option A: x+y=136 and x-y=34 is the correct answer.
Step-by-step explanation:
Let,
x and y be the two numbers.
According to given statement,
The sum of two numbers is 136.
x + y = 136 Eqn 1
The difference of two numbers is 34.
x - y = 34 Eqn 2
x+y=136 and x-y=34 is the system of equations that could be used to solve and determine the numbers.
Hence,
Option A: x+y=136 and x-y=34 is the correct answer.

Another doctor suggest that for women, there are two researched formulas to find a maximum heart rate m in terms of age a m=220 -a m=206-(0.88xa) using the two equations, at what age year and months would both formulas give the same solution for m? How did yoh find this age? Is your solution reasonable? Explain your reasoning
Answer:
At 116 years and 8 months, the rate would be the same
The solution is not reasonable
Step-by-step explanation:
Given
[tex]m = 220 - a[/tex]
[tex]m = 206 - (0.88 * a)[/tex]
Solving (a): At what age would both rate be equal
To do this, we simply equate both expressions.
[tex]m = m[/tex]
This gives
[tex]220 - a = 206 - (0.88 * a)[/tex]
[tex]220 - a = 206 - 0.88 a[/tex]
Collect Like Terms
[tex]0.88a - a = 206 - 220[/tex]
[tex]-0.12a=-14[/tex]
Divide both sides by -0.12
[tex]\frac{-0.12a}{-0.12} =\frac{-14}{-0.12}[/tex]
[tex]a =\frac{-14}{-0.12}[/tex]
[tex]a =\frac{14}{0.12}[/tex]
Multiply fraction by 100/100
[tex]a = \frac{14*100}{0.12*100}[/tex]
[tex]a = \frac{1400}{12}[/tex]
[tex]a = 116\frac{8}{12}[/tex]
This implies at 116 years and 8 months, the rate would be the same
Is the solution reasonable?
No, it is not reasonable, considering the life expectancy of women to be around 70-72 years old.
116 years old is way too bigger than the life expectancy.

Note: Cost of second iron must be 1200 instead of 12000.
Given:
Cost of first electric iron = 900
Grain on first electric iron = 10%
Cost of second electric iron = 1200
Loss on second electric iron = 5%
To find:
The correct statement for the given problem.
Solution:
We have,
Cost of first electric iron = 900
Grain on first electric iron = 10%
Profit on first iron is
[tex]900\times \dfrac{10}{100}=90[/tex]
Cost of second electric iron = 1200
Loss on second electric iron = 5%
Loss of second iron is
[tex]1200\times \dfrac{5}{100}=60[/tex]
Now, profit is 90 and loss is 60. Profit is more than loss.
Exact profit = Profit - Loss
Exact profit = 90 - 60
Exact profit = 30
Therefore, Avinash get a profit of Rs. 30 on the transactions. Hence, the correct option is c.

4)Infinitely many
Answer: Your answer should be 1.
The given equation 2(x + 2) = 2 + 2x has zero solution. which is the correct answer would be an option (A).
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The equation is given in the question following:
2(x + 2) = 2 + 2x
We have to determine the number of solutions to the given equation.
As per the given question, we have
⇒ 2(x + 2) = 2 + 2x
Apply the distributive property of multiplication, and
⇒ 2x + 4 = 2 + 2x
Rearrange the terms of variable x in the above equation,
⇒ 2x - 2x = 2 - 4
⇒ 0 = -2
This is not true, so the given equation has no solution.
Thus, the equation 2(x + 2) = 2 + 2x has zero solution.
