Reasoning Explain why either a or b must be 0 if ab = 0, but neither a nor b
must be 4 when ab = 4.

Answers

Answer 1
By the zero product property, a or b must be 0 if ab = 0. Or you could solve for each variable.

Divide both sides by b:
b=0/a —> b=0

Divide both sides by b:
a=0/b —> a=0

Hmm A could be 4 and b could be 1 because 4*1=4

Which equation could represent a vertical asymptote of the graph of the function?
O x=0
O y = 0
Ox= -1
O y=-1

Answers

Answer:

X=-1

Step-by-step explanation:

The correct equation could represent a vertical asymptote of the graph of the function is,

⇒ x = -1

What is mean by Function?

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Now, According to the given table, we see that for x = -1, the function is not defined, that means that the rational function has a restriction there, and such restriction is shown as an asymptote in the graph of the function.

So, basically, we could say that the given rational function has one asymptote and it's at x = -1, which is a vertical asymptote, because all forms like x = k, are vertical lines, that is, they are parallel to the vertical axis.

Therefore, The correct equation could represent a vertical asymptote of the graph of the function is,

⇒ x = -1

2. How many solutions to the equation 2x +2 = 2(x+3)
O 1 solution
O Infinitely many solutions
O No solution

Answers

Answer:

O No solution

Step-by-step explanation:

2x +2 = 2(x+3)

Distributer the 2 on the right side.

2x + 2 = 2x + 6

Subtract 2x from both sides.

2 = 6

2 = 6 is a false statement.

Since we did two legal steps to solve the equation, and we ended up with a false statement, that means this equation has no solution.

Answer: O No solution

Find the area of the composite figure

Answers

Step-by-step explanation:

You're only finding half of a circle but since you have 2, it is possible to just do the area of a circle which is [tex]\pi r ^{2} [/tex]

3.5 x 3.5 = 12.25

Because the radius of your circle is 3.5m but there are 2 of them you subtract 7 from 18 which give you 11:

Then you multiply 11 by 7.

= 77

Then add it all together.

[tex]a = (77 + 12.25\pi)m^{2} [/tex]

Answer:

Step-by-step explanation:

Combine like terms into a single fraction:

[tex]\frac{1}{2} p+75=100[/tex]

[tex]\frac{1p}{2} +75=100[/tex]

Multiply by 1:

[tex]\frac{1p}{2}+75=100[/tex]

[tex]\frac{p}{2} +75=100[/tex]

Subtract 75 from both sides of the equation:

[tex]\frac{p}{2} +75=100[/tex]

[tex]\frac{p}{2} +75-75=100-75[/tex]

Simplify:

Subtract the numbers:

[tex]\frac{p}{2} +75-75=100-75[/tex]

[tex]\frac{p}{2} =100-75[/tex]

Subtract the numbers:

[tex]\frac{p}{2} =100-75[/tex]

[tex]\frac{p}{2} =25[/tex]

Multiply all terms by the same value to eliminate fraction denominators:

[tex]\frac{p}{2} =25[/tex]

[tex]2*\frac{p}{2} =2*25[/tex]

7(x-2)=28 Can somebody help me and show the steps?

Answers

Since the 7 is in front of the parentheses you must multiply it by everything inside the parentheses. 7 times X is 7X and 7 times -2 is -14. Then you need to make the X be by itself on one side, to do that you have to add 14 to -14 to make it disappear, and also add 14 to the other side, to 28. Then you divide both sides by 7 to make X be by itself.

7(x-2)=28
7X-14=28
7x=42
X=6

DO multiplication them convert like terms

Answer:

-3s² + 16s - 7

Step-by-step explanation:

Remember to follow FOIL. FOIL stands for (First, Outside, Inside, Last).

First, distribute -3s to s and -10, and 7 to -2s and -1:

-3s(s - 10) = -3s² + 30s

7(-2s - 1) = -14s - 7

Next, combine like terms:

-3s² + 30s - 14s - 7

-3s² + (30s - 14s) - 7

-3s² + 16s - 7

-3s² + 16s - 7 is your answer.

Set up a proportion.

The total side of the “top” line is 8 + 10 = 18. The total side of the “bottom” line is 45. This makes the ratio 18/45.

Now we are trying to find the “larger” bottom segment, let it be x. Because the lines are parallel, the ratio of the “larger” top and bottom segments is equal to the ratio of the whole top and bottom lines.

So 18/45 = 10/x

Reduce 2/5 = 10/x

Cross multiply 2x = 50

Solve x = 25
