Answer:
0 or 6x+4=6x+4 (Technically no slope at all!!)
Step-by-step explanation:
You need to do distributive property and then solve for x!!
meaning the 2(3x+2) has to get distributive property process.
6x+4=6x+4
That shall be equal together!!! (You could stop here!!)

What is the general form of a quadratic equation?The general form of a quadratic equation is [tex]ax^{2} +bx+c=0[/tex] with [tex]a\neq 0[/tex].
As we know the minimum value of a quadratic function is [tex]\frac{4ac-b^{2} }{4a}[/tex] when a>0
For f(x) a>0 so minimum value of f(x) = [tex]\frac{4*1*8-(-2)^2}{4*1}[/tex]=7
From the graph, the maximum value of g(x) =12
So, the difference between the maximum value of g(x) and the minimum value of f(x) =12-7 =5
Hence, the difference between the maximum value of g(x) and the minimum value of f(x) is 5.

You are calculating how many seats there are at Wrigley
Field in Chicago, Illinois. You count that there are 1,487 rows
Each row has 28 seats.
How many seats are there in the whole field?
Answer:
41,636
Step-by-step explanation:
Easy, on each row, there are 28 seats, and we know there's 1487 rows in total.
Hence, number of rows multiplied by number of seats counted
1487 × 28
=41,636
(Dang, that's alot of seats then)
Describe how to compare the two ratios 5:8 to 7:9. Tell each step to set up the ratios, then explain what to do to be able to compare the ratios. Finally make sure to answer how the ratios compare. ~ 100 POINTS AND ILL GIVE YOU BRAINLIEST IF YOU ANSWER CORRECTLY AND 5 SENTENCES NEEDED
Answer:
5/8 is smaller.
Step-by-step explanation:
A ratio is just a different type of fraction, a 5:8 ratio means 5/8 which is 0.625. A 7:9 ratio equals 7/9 which is 0.777777
Then to compare them you see which is smaller or bigger.
0.77777 is bigger than 0.625 so we know that 0.77777777 which was the 7:9 ratio is the bigger one.

Please I’m desperate I already tried and it was wrong I’ll mark Brainlist
Answer:
y = (-5/2)X + 4
Step-by-step explanation:
we know that the equation of a line is y = mx + b
m = -5/2
so
y = -5/2x + b
to find b:
-6 = -10 + b
b = 4
so
y = (-5/2)X + 4
Answer:
Use the point-slope form of a linear equation:
[tex]y-y_1=m(x-x_1)[/tex]
where:
[tex]m[/tex] = slope[tex](x_1,y_1)[/tex] = point on lineGiven:
[tex]m=-\dfrac52[/tex][tex](x_1,y_1)=(4,-6)[/tex]Substitute given information into the equation:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-(-6)=-\dfrac52(x-4)[/tex]
[tex]\implies y+6=-\dfrac52x+10[/tex]
[tex]\implies y=-\dfrac52x+4[/tex]
Therefore, the equation of the line in different formats is:
[tex]\textsf{slope-intercept form: }y=-\dfrac52x+4[/tex]

Romeo has a work that pays 100 pesos per 1 hour. How much would he make in 10 hours?
Answer: he would get 1000
Step-by-step explanation:
100 x 10 =1000
Answer:
$1,000
Step-by-step explanation:
Since he makes 100 pesos in 1 hour, all you have to do is multiply 100 by 10. When multiplying a number by 10, all you do is move the decimal point back one. In this case, our decimal point is imaginary, so when we move it back one, you just add a zero at the end of the number. That gives you 1000.

The total US dollars it cost to Tom to get the rupees he wants for the trip of India is $270 round to the nearest dollar.
How to calculate the percentage?Percentage of a number is the part of the number expressed in the in every hundred. Percentage of a number is expressed with the symbol '%'.
To calculate the percentage part of number, multiply it with the original number and divide with 100.
Tom is exchanging money for his trip to india. The exchange rate of us dollars to indian rupees is,
[tex]r=\dfrac{1}{45.897}[/tex]
Tom needs 11,550 rupees. The dollars need for 11550 Indian rupees are,
[tex]n=\dfrac{11550}{45.897}\\n=251.65[/tex]
The currency exchange service he is using charges a fee of 7.25% after the exchange is made. Thus the total dollar requied after the service charge is,
[tex]n=251.65+\dfrac{7.25}{100}\times251.65\\n=251.65+18.245\\n=269.895\\n\approx270[/tex]

First, distribute the given problem :
