The roots of a quadratic equation are 7 and -3. Which quadratic equation has these roots?
(x + 7) (x – 3) = 0
(x - 7) (x + 3) = 0
(x – 7) (x – 3) = 0
(x + 7) (x + 3) = 0
Fifteen is equal to 7 more than twice a number. Write the equation and
nd the number.

Since both sides of the equation are equal, x has infinite solutions.
Determine which ordered pair is a solution of y= x+2/5
Wouldn’t it be (0, 2/5)?
Answer:
(-1,2/5) i'm pretty sure
Step-by-step explanation:
Answer:
(2, 2 2/5)
Step-by-step explanation:
(0, 2/5) is correct, and since the slope is 1, adding any number to both the x and the y would still make it a solution.
In this case, you could add 2 to both x and y, resulting in (2, 2 2/5).

data will be collected on the following variables. which variable can be considered discrete
Variables that can only take on a finite number of values are called "discrete variables." All qualitative variables are discrete. Some quantitative variables are discrete, such as performance rated as 1,2,3,4, or 5, or temperature rounded to the nearest degree.
It was -8°F in the morning. The temperature increased throughout the day, and in the afternoon, it was 11°F. How much did the temperature change?
Answer:
19
Step-by-step explanation
This is simple
I will teach you a simple technique
Count them, don't count the -8
-8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11
You are just subtracting, but instead counting.
I said not to count -8, because normally in subtraction, we normally don't count the number we are subracting.
for example
8 - 7 = 1
so counting technique
8 - 7, 6, 5, 4, 3, 2, 1
there are 7 numbers, if i didn't count the 8
so it is right.
hope you understand :-)

Find the sum or difference for questions 1-3. 20.58 – 13.3 A. 6.88 B. 7.28 C. 33.88 D. 7.58 plz respond fast
Answer:
B
Step-by-step explanation:
20.58
- 13.3
= 7.28 here u go
The difference between 20.58 and 13.3 is 7.28.
What is a decimal ?Decimal is a dot or a point which separates the whole part and the fractional part of given number.
According to the given question
The difference of 20.58 and 13.3 is
(20.58 - 13.3 ) can be written as (20.58 - 13.30 ).
If we remove the decimals and simply subtract 1330 from 2058 we get
(2058 - 1330)
= 728 and putting back the decimals in their actual place which was two digits from the leftmost side we get
= 7.28
So the difference between 20.58 and 13.3 is 7.28.

What is the ratio AC: CB?
Answer:
D. 1 : 2
Step-by-step explanation:
Given:
A(-6, -2),
B(6, 7),
C(-2, 1)
Required:
Ratio of AC : CB
SOLUTION:
Find AC:
[tex] AC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] A(-6, -2) = (x_1, y_1) [/tex]
[tex] C(-2, 1) = (x_2, y_2) [/tex]
[tex] AC = \sqrt{(-2 -(-6))^2 + (1 -(-2))^2} [/tex]
[tex] AC = \sqrt{(4)^2 + (3)^2} [/tex]
[tex] AC = \sqrt{16 + 9} = \sqrt{25} [/tex]
[tex] AC = 5 [/tex]
Find CB:
[tex] CB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] C(-2, 1) = (x_1, y_1) [/tex]
[tex] B(6, 7) = (x_2, y_2) [/tex]
[tex] CB = \sqrt{(6 -(-2))^2 + (7 - 1)^2} [/tex]
[tex] CB = \sqrt{(8)^2 + (6)^2} [/tex]
[tex] CB = \sqrt{64 + 36} = \sqrt{100} [/tex]
[tex] CB = 10 [/tex]
Find AC : CB
AC : CB = 5 : 10 = 1 : 2
2). Bill has twice as many candies as Fred. Tim has 3 fewer than 3 times as many candles as Fred.
In all, they have 177 candies. How many do they each have?
Step-by-step explanation:
Answer:-[tex]\tt{Let \ the \ candies \ taken \ by \ Fred \ be \ x.}[/tex]
Now, let's Solve!
So, according to Question,
Bill = 2x
Tim = 3x-3
Total Candies = 177.
[tex]\bf{x+2x+3x-3=177}[/tex]
Totalling x,
[tex]\bf{6x-3=177}[/tex]
[tex]\bf{6x=177+3}[/tex]
[tex]\bf{6x = 180}[/tex]
[tex]\boxed{\sf{x = 30}}[/tex]
So, Fred has 30 candies.
Bill's Candies = 2×30 = 60 Candies
Tim's Candies = 3×30-3 = 90-3 = 87 Candies.

The ratio of boys to girls in a class is 3:4. There are 35 students in the class. How many students are girls?
Answer:
20 students are girls. (15 are boys)
Step-by-step explanation:
if the ratio is 3:4 and the total students is 35, you can make the following equation:
3x + 4x = 35
7x = 35
x = 5
then, multiply x by 4.
5*4 = 20.
20 students are girls. (15 are boys.)
