How to respond to "good talk good talk"
Answer:
Step-by-step explanation:
If the person who sent “good talk good talk ” message to you is someone you know very well, but you have not heard from him or her for quite a while, answering with “What took you so long? I missed you!” will be the perfect reply. Simply asking back with “How are you” without any greetings is also fine.

What is the slope of the line
-4+7= 2y - 3
Answer: 0
Step-by-step explanation:
Rewrite as y = mx + b form, where m is slope and b is the y-intercept.
2y - 3 = -4 + 7
2y = 3
y = 3/2
There is only the y- intercept, 3/2, therefore the slope is 0.
A balloon has a radius of 7.25 cm. What is the approximate area of the circle, rounded to the nearest whole number?
Answer:
165 square cm
Step-by-step explanation:
Area of a circle is [tex]\pi r^2[/tex], where r = radius. We're given the radius as 7.25.
[tex]3.14 * 7.25^2[/tex] [tex]3.14 * 52.5625[/tex] [tex]165.04625[/tex] 165.04625 ≈ 165 square cmTherefore, the answer is 165 square cm.

however, is the same cat wearing different costumes.
to get the slope of a straight line we only need two points off of it, hmmm let's use from the table (-1 , 13) and (2 , 1)
[tex](\stackrel{x_1}{-1}~,~\stackrel{y_1}{13})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{1}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{1}-\stackrel{y1}{13}}}{\underset{run} {\underset{x_2}{2}-\underset{x_1}{(-1)}}}\implies \cfrac{-12}{2+1}\implies \cfrac{-12}{3}\implies -4[/tex]
The required rate of change in the slope-intercept form is -4. Option A is correct.
What is the slope of the line?The slope of the line is the tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
Two coordinates from the table,
(-2, 17) and (-1, 13)
Now,
Rate of change = slope of the function = (13 - 17) / (-1 - (-2))
= -4 / 1
= -4
Thus, the required rate of change in the slope-intercept form is -4. Option A is correct.

How to solve graph 5+h>7
Answer:
h > 2
Step-by-step explanation:
It may look hard, but it is not really.
1. Solve
Here we have the equation 5+h>7.
All we have to do to find h is to subtract 5 from both sides.
5+h>7
-5 -5
When you subtract 5 from both sides, you get
5 - 5 = 0
7 - 5 = 2
All is left is 0+h>2, or h > 2.
2. Substitute
To make sure, (I do this but you can if you want to) I will substitute.
The values of h have to be greater than 2. So, Let's substitute 3.
5 + h > 7 --> 5 + 3 > 7
It's simple math.
5+3=8
8>7
Now, also to confirm, let's try a value less than 2, 1.
5 + h > 7
5 + 1 > 7
6 > 7 is not true, so it is confirmed that anything less than 2 is not true and anything greater is true.
Hence, h > 2
Hope this helps :)

arvin has a bake shop he sold 85 cakes today that is 16 cakes fewer than yesterday how many cakes did he sell yesterday
NEED SOLUTION EXPLAIN PLEASE
cake sold today :- 85
cake sold yesterday :- X
relationship between caked sold :-
Today cake sold = cake sold yesterday- 16 (ATQ)
85 = x -16
85+16= x = 101 cakes
so Arvin sold 101 cakes yesterday
Answer:
Its 101
Hope this will help you
Step-by-step explanation:
Cake he sold today-85
Let the cake he sold yesterday be x,
x = 85+16
Therefore, x= 101
Therefore, He sold 101 cakes yesterday
Use elimination to solve for x and y: -2x-y=9 2x-9y=1
Group of answer choices A. (5, 1) B. (-1, -7) C. (-4, -1) D. (-1, -4)
Answer:
C
Step-by-step explanation:
Label the two equations:
-2x -y= 9 -----(1)
2x -9y= 1 -----(2)
(1) +(2):
-2x -y +2x -9y= 9 +1
-2x +2x -y -9y= 10
Simplify:
-10y= 10
y= 10 ÷(-10)
y= -1
Substitute y= -1 into (2):
2x -9(-1)= 1
2x +9= 1
2x= 1 -9
2x= -8
x= -8 ÷2
x= -4
Thus, the solution is (-4, -1).
How do you factorise 6x-9
Answer:
6 x a number - 9 = factored
In this case, since the number is not declared as a specific number, this is the key to us factoring.
Like the number could be 6. ↓
Factoring:
[tex]6*6-9=27\\6*3-9=9\\6*9-9=45[/tex]
bonus even factor:
[tex]6*2-9=3[/tex]
These are factors and Least common multiples of 6 and 9.
Because 9 and 3 show up during half of the problem, and these are related to 6 and 9, the parents, we could measure this on a mathematical scale that this proves the factors correct.
There are other ways to factor this. See comments.

1. The polynomial of degree 5, P(x) has leading coefficient 1, has roots of multiplicity 2 at x=1 and x=0 and a root of multiplicity 1 at x= -5 Find a possible formula for P(x)
The degree of the polynomial P(x) is the highest power of the polynomial P(X)
A possible formula for P(x) is [tex]P(x) =(x + 5)x^2(x - 1)^2 \\[/tex]
How to determine the polynomialThe given parameters are:
Roots of multiplicity 2 at x=1 and x=0
Root of multiplicity 1 at x= -5
Write out the roots
x=1 and x=0 ------- Multiplicity 2
x = -5 ------- Multiplicity 1
Equate the roots to 0
x - 1 = 0 and x = 0 ------- Multiplicity 2
x + 5= 0 ------- Multiplicity 1
Place the multiplicities as the exponents of the roots
(x - 1)^2 = 0 and x^2 = 0
(x + 5)^1 = 0
Multiply the expressions
[tex](x - 1)^2 * x^2 * (x + 5)^1 = 0 * 0 * 0[/tex]
This gives
[tex](x - 1)^2 * x^2 * (x + 5) = 0[/tex]
Rewrite as:
[tex](x + 5)x^2(x - 1)^2 = 0[/tex]
Replace 0 with P(x)
[tex]P(x) =(x + 5)x^2(x - 1)^2[/tex]
Hence, a possible formula for P(x) is [tex]P(x) =(x + 5)x^2(x - 1)^2 \\[/tex]

Given the functions f(x)=7-2x and g(x)=5x-3 find g(f(-4)) find f(g(x))
Answer:
g(f(-4)) = -8

Step-by-step explanation:
g(f(-4)):
Plug in the equation f(x) into the variable x of g(x), we have:
[tex](gof)= 5(7-2x)-3[/tex]
Plug in x = -4 and the answer is -8
f(g(x)):

Find the exact value of y.
Answer:
[tex]y = 2\sqrt{10}[/tex]
Step-by-step explanation:
In left small right triangle: we have the square of left side = 5^2 + y^2 = 25 + y^2
In right small right triangle: we have the square of right side = 8^2 + y^2 = 64 + y^2
In the large right triangle, we have (25 + y^2) + (64 + y^2) = (5 + 8)^2
89 + 2y^2 = 13^2 = 169
2y^2 = 169 - 89 = 80
y = 80/2 = 40
so
[tex]y=\sqrt{40} = 2\sqrt{10}[/tex]
-3x+3y=4 -x+y=3 substitution
Answer: No solution
Step-by-step explanation:
-3x+3y=4
-x+y=3
We will rewrite the first equation and then substitute it into the second equation since we are solving by substitution.
Rewriting
-3x + 3y = 4
3y = 4 + 3x
y = [tex]\frac{4}{3}[/tex] + x
Substituting
-x + y = 3
-x + ([tex]\frac{4}{3}[/tex] + x) = 3
-x + [tex]\frac{4}{3}[/tex] + x = 3
[tex]\frac{4}{3}[/tex] = 3
