Answer: 4
Step-by-step explanation: compute the distance between (x1, y1), (x2, y2):
(8 -4)² + [ -1 - (-1) ]² = 4
Answer:
4
Step-by-step explanation:
X1 = 4
X2= 8
Y1 = -1
Y2= -1
Distance Formula = √(X2-X1)² + (Y2-y1)²
Step 1. calculate (X2-X1)²
(8 - 4)2 = 16
Step 2. calculate (Y2-Y1)²
(-1 - -1)2 = 0
Step 3. calculate √16 + 0
= 4

1.)Which has greater density?
object
fluid
neither
2.)The object will
sink
float
be suspended
in the water column.
Answer:
1. Object
2. Sink
Step-by-step explanation:
1.5 < 1, the object is denser than the fluid
When an object is denser than a fluid it is submerged in, the object will sink.

1. DIVING A submarine descends 32 feet below the surface. It rises 13 feet to look at a coral reef. Write an addition sentence to find its current depth.
Answer:
-32 + 13 = -19
Step-by-step explanation:
It descends 32 feet, which can be said as -32 feet, and then goes up 13 feet, so you add 13 feet. We can then solve and get -32+13=-19
Evaluate the following function f(x) = 2x + 4 for f(3)
Answer:
the answer is b
Step-by-step explanation:
In the fall, you charge your neighbors $9 for going to their house to rake leaves, then $6 for every
hour you rake. If you make $51 one day, how many hours did you spend raking?
1. Summarize the data given.
You know that you made $51 in just one day. You charge $9 for going to their house, plus $6 hours for raking.
9 + 6x = 51
X = The Hours Spent Raking
2. Turn the equation so then 6x is by itself.
9 + 6x = 51
-9 -9
6x = 42
3. Remove the number, so x remains by itself.
6x = 42
/6 /6
x = 7
So that means, you spent 7 hours raking leaves on the day I made 51 dollars.
Answer:
You spent 7 hours.
Step-by-step explanation:
First add 9 and 6 together which is 15 and then you continue to add 6 until you reach 51. I added 6 to my sum 7 times .
Abby is adopting kittens from the pet store. if there are 18 kittens, how many ways can she choose 2 kittens? **the answer isnt 9 or 32**
Answer:
153 ways.
Step-by-step explanation:
The answer is the number of combinations of 2 from 18
= 18! / 2! (18-2)!
= 18! / 2! 16!
= 18*17*16! / 2! 16!
= 18 * 17 / 2*1
= 9 * 17
= 153 ways.

A survey of Micki's customers showed that 1,800 out of 2,200 of the customers buying carrots would buy organic carrots if the carrots were placed near the front of the store. In the first month, 1,500 of those 2,200 customers actually bought the organic carrots. What was the percent error in the survey estimate of the number of people buying organic carrots?
Answer:
13.63%
Step-by-step explanation:
The computation of the percent error is shown below;
= (Showing amount - first month amount) ÷ (Actual purchased)
= (1,800 - 1,500) ÷ (2,200)
= (300) ÷ (2,200)
= 13.63%
Hence, the percent error is 13.63%
We simply applied the above formula so that the correct percent error could come and the same is to be applied
Answer:
83.3%

A quadratic equation is an equation whose leading coefficient is of the second degree. The correct option is C.
What is a quadratic equation?A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
Its roots are given as:
[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
The second-degree polynomial function that has roots –3 and 5 are,
f(x) = (x+3)(x-5)
f(x) = x² + 3x - 5x -15
f(x) = x² - 2x - 15
Now, it is needed that the polynomial's leading coefficient should be 2. Therefore, the polynomial should be multiplied by 2. Thus, the polynomial will be,
f(x) = 2x² - 4x - 30

The solution to the equation 3x + 7 = 16 - 2x is x = 9/5.
Option A is the correct answer.
We have,
To solve the equation 3x + 7 = 16 - 2x for x, we need to isolate the variable x on one side of the equation.
Let's solve it step by step:
Start with the original equation:
3x + 7 = 16 - 2x
- Add 2x to both sides of the equation to get rid of the -2x on the right side: 3x + 2x + 7 = 16 - 2x + 2x
- Simplifying, we have: 5x + 7 = 16
- Next, subtract 7 from both sides of the equation to isolate the term with x: 5x + 7 - 7 = 16 - 7
- Simplifying, we have: 5x = 9
- Finally, divide both sides of the equation by 5 to solve for x: (5x)/5 = 9/5
- Simplifying, we have: x = 9/5
Therefore,
The solution to the equation 3x + 7 = 16 - 2x is x = 9/5.

2, 4, 5, 7, 15Write the equation of the line that it is parallel to 5x = 1 - 3y and passes through (9,4).
Answer:
y = -5/3x + 57/3
Step-by-step explanation:
Solve 5x = 1 -3y for y
so 3y = -5x + 1 divided by by 3
y = -5/3x +1/3
Since its parallel it has the same slope
To find the y-intercept you need to move 9 to 0
so the intercept = 12/3 + 45/3 = 57/3
