Help! How do i find a solution set? (I have a texas ti graphing calculator if that helps) An example is

(x - a)(x + b) = 0

How would I find the solution set for this?

Please explain to me in an easy to understand, step by step way.

If you know how to use a texas TI calculator, you can also explain to me how to do it on the calculator, but that is not required

Answers

Answer 1

Answer:

The solution set is given by {a, -b}.

Step-by-step explanation:

We have the equation,

[tex](x - a)(x + b) = 0[/tex]

Equating the factors to 0 gives,

[tex](x - a)=0[/tex] and [tex](x + b)=0[/tex]

i.e. x = a and x = -b

So, the solutions of the equation [tex](x - a)(x + b) = 0[/tex] are x= a and x= -b.

Thus, the solution set is given by {a, -b}.

How do I find the area of the isosceles triangle?

Answers

Use the Pythagorean Theorem to find 'h'.

[tex]\sf a^2+b^2=c^2[/tex]

For right triangles, where 'a' and 'b' are the two legs and 'c' is the hypotenuse.

Divide the base by 2 to find the base length of one of the right triangles. 32/2 = 16. Now apply the Pythagorean Theorem:

[tex]\sf 16^2+b^2=20^2[/tex]

Simplify:

[tex]\sf 256+b^2=400[/tex]

Subtract 256 to both sides:

[tex]\sf b^2=144[/tex]

Take the square root of both sides:

[tex]\sf b = 12[/tex]

So the height is 12cm. Apply the formula for the area of a triangle:

[tex]\sf A=\frac{1}{2}bh[/tex]

[tex]\sf A=\frac{1}{2}(32)(12)[/tex]

[tex]\sf A=192cm^2[/tex]

Your school is located at (2,−1), which is 2 blocks east and 1 block south of the center of town. To get from your house to the school, you walk 5 blocks west and 2 blocks north. a. What ordered pair corresponds to the location of your house?

Answers

Final answer:

Starting from your school's location (2,-1), by subtracting 5 from the x-coordinate for walking west, and adding 2 to the y-coordinate for walking north, the location of your house corresponds the ordered pair (-3,1).

Explanation:

Given your school is at (2,-1) and you walk 5 blocks west and 2 blocks north to reach your school, we can determine the location of your house. If we think of the coordinate system with east being positive along the x-axis and north as positive along the y-axis, then walking west (the opposite direction of positive x) means subtracting from the x-coordinate and walking north (the positive y direction) means adding to the y-coordinate.

So, starting from the school's location (2,-1), to account for your walk, subtract 5 (for walking west) from the x-coordinate, resulting in -3, and add 2 (for going north) to the y-coordinate, resulting in 1. Thus, the location of your house corresponds to the ordered pair (-3,1).

A minor league baseball team plays 101 games in a season. If the team won 14 more than twice as many games as they lost, how many wins and loses did the team have?

Answers

A minor league plays 101 games,
They win 14 more than twice as many as they lost.
How many wins and loses?

Okay, simple.
First, write a simple addition equation. In this case wins = w and losses = l.
l + w = 101.

Now, we have to figure out a way to make one of the terms the same term as the other, in this case we can change the terms of w to l.
l = l
w = 2l +14 (14 more than twice the amount)

Okay. So plug in the new amount for w.
l + 2l + 14 = 101. Great! we now have a simple equation. lets solve.
put similar terms together.
3l + 14 = 101
3l = 87
l = 29
So, we have 29 loses, and
w = 2(29) + 14
72 wins!
To check,
72 + 29 = 101, correct!

Jess observed that 60% of the people at a mall on a particular day shopped for clothes. If 2500 people at the mall did not shop for clothes that day, the number of people who shopped for clothes that day was ______. (only put numeric values, no other symbols)

Answers

If 60% did not, then 40% did

Set up a proportion.
60%/ 2500 = 40%/x
60% x = 2500 * 40%
x = (40% / 60%) * 2500
x = (0.4 / 0.6) * 2500
x = 1666.667
You have to round this, but which way? I would go down.

You could do this another way. Find 100% first.
60% of x = 2500
x = 2500 / 0.6
x = 4166.666666

That is the total number of people he saw.
Take out the 2500
4166.66666 - 2500 = 1666.6666

h(t)=50− 5 t ​
h(35)=?

Answers

Answer:

Step-by-step explanation:

H(t) = 50 - t/5

h(35)=50-35/5

=50-7

=43

h(35) = 43

The quantity represented by h(t) is -125 at time t=35.

The function h(t) represents a certain quantity (for example, height, distance, etc.) as a function of time ‘t’. Here, you want to find the value of h(t) at t=35.

We can substitute t=35 into the function h(t):

h(35) = 50 - 5*35

Now, calculate the expression on the right side to find the value of h(35). This will give you the desired quantity at time t=35. Remember to follow the order of operations (multiplication before subtraction). Let’s calculate it:

h(35) = 50 - 5*35 = 50 - 175 = -125

So, h(35) = -125. This means that the quantity represented by h(t) is -125 at time t=35.

Similarities between justice and revenge

Answers

Justice and revenge are both punishments and Justice is a form of revenge.

Final answer:

Justice and revenge differ in intentions and outcomes. Justice focuses on fairness and societal laws, while revenge is driven by personal vendettas. It's crucial to differentiate between the two concepts to avoid perpetuating harm.

Explanation:

Justice and revenge both involve the desire for consequences towards a wrongdoing, but they differ in their intentions and outcomes. While justice aims for fairness and upholding societal laws, revenge seeks to harm those who have caused harm, often driven by personal emotions.

One key difference between justice and revenge is that justice is typically carried out within a legal framework and aims to restore balance in society, whereas revenge is driven by personal vendetta and can perpetuate cycles of violence.

It's essential to differentiate between the two concepts, as justice aligns with societal norms and legal systems, while revenge risks leading to further harm and conflict.

Distributive property of
36+ 9y

Answers

find the greatest common factor (GCF)
in this case it would be 9

divide each term by the GCF
36 / 9 = 4
9y / 9 = y

put the two "new" terms in parenthesis and the GCF in front of it
9 (4 + y)
it could also be 9 (y + 4) because of Commutative Property of Addition
This problem in the distributive form would be 9(4+y) because the greatest common factor, or GCF, is 9. When you divide 36 by 9 you get 4 and 9 divided by 9 is one, therefore leaving the y.
To conclude the answer would be 9(4+y).

John has four more nickels than dimes in his pocket, for a total of $1.25. Which equation could be used to determine the numbet of dimes, x, in his pocket?

Answers

So, you have to have your equation in terms of dimes. What you said about what he has: four more nickels than dimes in his pocket. Will help with our equation.
We know what a nickel and dime is worth. A nickel is .05 and a dime is .1
We don't know how many dimes are in his pocket, since we're trying to solve it.
.1x+(4+x).05=1.25; 
In the parenthesis, it shows how there are four more nickels. Let's solve it now.
.1x + (4+x).05=1.25
.1x + .2+ .05x = 1.25; Let's add like terms.
.15x + .2 = 1.25; Subtract .2 from both sides.
.15x= 1.05
1.05÷.15= 7 =x
There are 7 dimes in his pocket, let's check our answer.
We now know there are 11 nickels, since there are four more nickels than dimes.
11(.05) +.1(7) = 1.25
.55+ .7 = 1.25
Now that we've tried it, we know there are 7 dimes in his pocket.

Use slope formula m= y2-y1/x2-x1 to find the slope of a line that passes through the points (–3, 8) and (4, –6).

Answers

Final answer:

The slope of the line passing through the points (−3, 8) and (4, −6) is calculated using the slope formula and results in a slope of −2.

Explanation:

To find the slope of the line that passes through the points (−3, 8) and (4, −6), we apply the slope formula m = (y2 − y1) / (x2 − x1). Let's designate the first point (−3, 8) as (x1, y1) and the second point (4, −6) as (x2, y2). Plugging these values into the formula, we get:

m = (−6 − 8) / (4 − (−3))

m = −14 / 7

m = −2

Therefore, the slope of the line between the two points is −2. The negative sign indicates that the line is descending from left to right.

Final answer:

To calculate the slope of a line that goes through the points (-3, 8) and (4, -6), apply the slope formula m = (y2 - y1) / (x2 - x1). After substituting the values, the slope is found to be -2.

Explanation:

To find the slope of the line that passes through the points –(3, 8) and (4, –6), we can use the slope formula, which is m = (y2 - y1) / (x2 - x1).

Using the given points, Point 1 (x1, y1) is (-3, 8) and Point 2 (x2, y2) is (4, -6). Substituting these values into the slope formula gives us:

m = (-6 - 8) / (4 - (-3))

m = (-14) / (7)

m = -2

Therefore, the slope of the line that passes through the given points is -2.
