Passes through origin means yint is 0
slope is -7

y=mx+b
m=slope
b=yint

yint=0
slope=-7

y=-7x+0
y=-7x is the equation

If you have a picture that shows line c on a graph, you could find your y-intercept or b. If not, you need the y-intercept to make an equation.

Helppppppp pleaseeeeee
Dahasolnce [82]

Step-by-step explanation:

The area, A, in square yards, of a rectangular garden, is given by the function.

A(x)=-2x^2+30x

We know that, the area of the rectangle is given by :

A=l\times b

Where l is length and b is breadth

A=-2x^2+30x\\\\A=2x\times (-x+15)

Length = 2x

Breadth = (15-x)

For zeoes,

2x\times (-x+15)=0\\\\x=15

Length = 15 yards

Breadth = (15-15) = 0 yards

Hence, this is the required solution.

The equation of a circle is x2 + y2 + Cx + Dy + E = 0. If the radius of the circle is decreased without changing the coordinates
valkas [14]

Answer:

Option E

Step-by-step explanation:

The standard equation of circle is:- (x-h)² + (y-k)² = r²

where (h,k) is center point and r is radius

If radius r is decreased then also (h,k) remains same, only r² increases

Equation given in question is x² + y² + Cx + Dx + E=0

So, C and D will remain same but E will increase

The late fee for library books is $2.00 plus 15 cents each day for a book that is late.If Maria's fee for a late book was $3.20,
tekilochka [14]

First we will subtract $2 from $3.2 since that is late fee to get $1.2.

Now we divide $1.2 by $0.15 to get number of cents hence 8 days.

The answer is Maria is 8 days too late to hand over the book.

Hope this helps.
