Answer:
y = 3x - 3
Step-by-step explanation:
Given, (2,3) and (-1,9), m = 3
Equation of a straight line is y = mx + c
Here, y = 3, x = 2 and m = 3
Substituting the values in y = mx + c we get,
3 = 3(2) + c
c + 6 = 3
c = 3 - 6
c = -3
So, the equation of the line is y = 3x - 3 (Answer).
f(x) = x². What is g(x)?
A. g(x) = -x² – 3
B. g(x) = -3x²
C. g(x) = x² - 3
D. g(x) = -x²
Answer:
A
Step-by-step explanation:
because g(x) is the opposite of f(x) minus three steps

Find the area of the parallelogram please.
Answer: 76.8 mi²
Step-by-step explanation:
The area of a parallelogram can be found be multiplying the base times the height.
A = B * H
A = 9.6 * 8
A = 76.8 mi²
Confused as to why this works? We use the same formula that we do for a rectangle because the "extra triangle" on the left can be moved to fill the empty space on the right. This then gives us a normal rectangle, which allows us to solve for the area
In this question we are provided with the base and height of a parallelogram and we are asked to calculate the area of the parallelogram using the formula.
It is given that the base is 9.6 mi and height is 8 mi.
We know,
[tex] \small\boxed{ \sf {Area_{(parallelogram)} = B × H}}[/tex]
Where,
B stand for BaseH stand for HeightSubstituting the values we get
[tex] \small\sf{ Area_{(parallelogram)} = (9.6 × 8) mi} = 76.8 {mi}^{2} [/tex]
Hence the area of the parallelogram is 76.8 mi².You buy a watch that cost $45.50. The tax on the watch is 7.5%. What is the final cost of the watch? *
You are asked to create a 5 LETTER password, how many different passwords can you create if.
a) All letters are capitals and repetition is allowed
b) All letters can be either capitals or lower case, but repetition is
not allowed.
Detailed explanations are most welcome.
We will see that the number of different combinations for each case are:
a) 11,881,376b) 311,875,200How many passwords can we make?
We have 5 selections for each password, we need to find the number of options for each one of these selections.
a) Here we can use only capitals an we can repeat, so for each selection (each letter), we have 26 options.
The total number of combinations will be equal to the product between the numbers of options:
C = 26*26*26*26*26 = 11,881,376
b)Now we can use either capitals or lower case, but we can't repeat. (Here I assume that A is different than a, so we can't use A two times, but we could use A and a).
Then we have 26*2 = 52 options.
For the first letter, we have 52 options.
For the second letter, we have 51 options (because one letter was already used).
For the third letter, we have 50 options, and so on.
The total number of combinations will be:
C = 52*51*50*49*48 = 311,875,200

The volume of a cone with diameter d (and hence radius d/2) and height h is
[tex]V_{\rm cone} = \dfrac\pi3 \left(\dfrac d2\right)^2 h[/tex]
so each scoop holds

The volume of a cylinder with base diameter d and height h is

so the coffee can contains

-2-0.5b+12=0.3b+6.2
Step-by-step explanation:
-2 -0.5b + 12 = 0.3b + 6.2
-2 + 12 - 6.2 = 0.3b + 0.5b
3.8 = 0.8b
b = 3.8/0.8
= 4.75
Answer:
4.75
Step-by-step explanation:
-2-0.5b + 12 = 0.3b + 6.2
Move all terms to the left:
-2-0.5b + 12 - (0.3b + 6.2) = 0
Add all the numbers together, and all the variables
-0.5b - (0.3b + 6.2) + 10 = 0
Get rid of parentheses
-0.5b - 0.3b - 6.2 + 10 = 0
Add all the numbers together, and all the variables
-0.8b + 3.8 = 0
Move all terms containing b to the left, all other terms to the right
-0.8b = -3.8
b= -3.8/-0.8
b= 4+0.6/0.8
b= 4.75

The multiples of 8 from 1 to 100 are: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, and 96.
How to calculate the multiples of the number 8?To calculate the multiples of 8 we must multiply 8 by any number and the result will be a multiple of 8.
To identify the multiples of 8 that are between the number 1 and 100, we must multiply the number 8 by the number sequence 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 .
So we will know properly are the multiples of 8 that are between 1 and 100 as shown below:
8 × 1 = 88 × 2 = 168 × 3 = 248 × 4 = 328 × 5 = 408 × 6 = 488 × 7 = 568 × 8 = 648 × 9 = 728 × 10 = 808 × 11 = 888 × 12 = 96Learn more about multiplication in: https://brainly.com/question/23536361

What value of 2c makes the equation true?
Answer:
[tex]\huge\boxed{\bf\:c = \frac{11}{4}}[/tex]
