There are ALOT of equations that can go through the point (7,4). So, pick a slope. it doesnt matter what it is. just pick a number. let us say you pick 3.

Your equation is now y=3x+b.

now you need to find b in respect to (7,4). plug 7 and 4 into the equation and solve for b.
now you have a function that runs through the coordinate (7,4)!

So if it is going completely horizontally, you know that it will begin with the equation y=?. If you use the point (7, 4) then you know that y is 4. Therefore, the answer would be y=4.

The product of (a − b)(a − b) is a2 − b2.<br> A. Sometimes<br> B. Always<br> C. Never

Damm [24]

$(a-b)(a-b)=a^2-2ab+b^2\\\\a^2-2ab+b^2=a^2-b^2\\2b^2=2ab\\b^2=ab\implies a=b \vee b=0$

So, sometimes.

WRITE THE equation THAT correctly represents the statement: 'After spending four- fifth of a certain amount of money, the money

Arte-miy333 [17]

Answer:

$\frac{4}{5} x = 25 + \frac{3}{10} x$

Step-by-step explanation:

four-fifth means 4/5 .

we let the amount of the money to be x.

so four-fifth of money =4/5 of x.

twenty Five more than three tenth of the initial amount means 25+3/4 of x.

the equation becomes

$\frac{4}{5} x = 25 + \frac{3}{10} x$

Please please help me I need to learn this for my school tmr thank u very much if you do help me !!

Answer:

Step 1 :

Split the figure into 3 parts

part 1: triangle with base = 7 + 2 + 6 = 15in, height = 7in

part 2 : Rectangle with breadth = 3 + 6 + 2= 11in and length 8in

Part 3 :Rectangle with breadth 2in and length 9in

Step 2 :

find the area of each part

Area of part 1

$\frac{1}{2} * base * height = \frac{1}{2}*15*7 = 52.5in^{2}$

Area of part 2

$length * breadth = 11*8 =88in^{2}$

Area of part 3

$length * breadth = 2*9 =18in^2$

Total area = 52.5 + 88 + 18 = 158.5 sqaure inches
