Write an equation of the line that passes through (1, -8) and is parallel to the line y = -3x - 7
Answers
Answer:
the desired new equation is y = -3x - 5
Step-by-step explanation:
The desired equation of this new (parallel) line has exactly the same form as the given line y = -3x - 7. Only the y-intercept will be different.
Starting with y = -3x - 7, replace x with the x-coordinate of the given point (1, -8) and y with the y-coordinate. We get:
-8 = -3(1) + C, where C is the new y-intercept and is to be determined.
Then C = -5, and the desired new equation is y = -3x - 5.
Which counterexample shows the conjecture “If the product of two numbers is positive, then the two numbers must both be positive” to be false?
(-3)(-1) = (+3)
(-3)(+1) = (-3)
(+3)(+1) = (+3)
(+3)(-1) = (-3)
Answers
Answer:
(-3)(-1) = (+3)
Step-by-step explanation:
In this question, we have to find the equation that proves the statement wrong.
The statement says that “If the product of two numbers is positive, then the two numbers must both be positive"
We can already make this statement false because both numbers doesn't only have to be positive in order to have the product of a positive number.
We know that if you multiply two negatives, the number turns positive.
Therefore, we can see that displayed in this equation: (-3)(-1) = (+3)
This is because (-3)(-1) = 3, and they both aren't positive numbers.
Answer:
(-3)(-1) = (+3)
Step-by-step explanation:
The counterexample would be that the product of two negative numbers is positive but the numbers are negative. For example, (-3)(-1) = (+3).

Which is the graph of the linear inequalityx2y>-6?
Answers
Answer:
We will graph the inequality in simplified form i.e [tex]y>-3[/tex]
The graph is shown in figure below
Step-by-step explanation:
Which is the graph of the linear inequality [tex]2y>-6[/tex]
(Note: Considering the inequality is 2y>-6 and x is typing mistake.)
First we will solve the inequality to find value of y
We have inequality:
[tex]2y>-6[/tex]
For finding y we have to divide both sides of inequality by 2
[tex]\frac{2y}{2}>\frac{-6}{2} \\y>-3[/tex]
Now, we will graph the inequality in simplified form i.e [tex]y>-3[/tex]
Inequality can be graphed on number line as well as graph paper.
Graph on number line
Since y is greater than -3, so all values greater than -3 will be included on the number line. An open circle will be drawn on -3, indicating -3 is not included but values greater than -3 are included. The figure A shows the graph
Graph on Graph paper
Since y is greater than -3, so all values greater than -3 will be included on the number line. A dotted line will appear on -3 and the region on right side of -3 (values greater than 3) will be shaded. The figure B shows the graph

Answer: 29
Step-by-step explanation: 180-146= 34-5 29.
Answer:
[A] 29
Explanation:
Equation: 180 = 146 + (x + 5)
The line adds up to 180, so we need to find what x is180 = 146 + (x + 5)
Switch Sides
146 + (x + 5) = 180
Remove Parenthesis
146 + x + 5 = 180
Group Like Terms
x + 146 + 5 = 180
Add: 146 + 5 = 151
x + 151 = 180
Subtract 151 From Each Side Of Equation
x + 151 - 151 = 180 - 151
x = 29

For the following, indicate whether a confidence interval for a proportion or mean should be constructed to estimate the variable of interest. Justify your response. Does chewing your food for a longer period of time reduce one's caloric intake of food at dinner? A researcher requires a sample of 75 healthy males to chew their food twice as long as they normally do. The researcher then records the calorie consumption at dinner.
Answers
Answer:
A confidence interval for a mean should be constructed to estimate the variable of interest.
Step-by-step explanation:
The confidence interval for a mean uses the sample mean to estimate the true population mean. Since it is a confidence interval, instead of a single number for the mean, the result shows a lower estimate and an upper estimate of the mean. In this experiment, the confidence interval cannot be for a proportion since the population of healthy males is unknown, but the calculation is being done with a sample of 75 healthy males.
Answer:
A confidence interval for a mean

Step-by-step explanation:
Step 1: Define Equation
-w - 2 = 42
Step 2: Solve for w
Add 2 to both sides: -w = 44Divide -1 on both sides: w = -44Step 3: Check
Plug in w into the original equation to verify it's a solution.
Substitute in w: -(-44) - 2 = 42Multiply: 44 - 2 = 42Subtract: 42 = 42Here we see that 42 does indeed equal 42.
∴ w = -44 is the solution to the equation.
