How do you write the equation for intercept (4,-3), m=-1

Digiron [165]3 years ago

Answer:

\large\boxed{y=-x+1}

Step-by-step explanation:

The slope-intercept from of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

<em />

We have the slope <em>m = -1</em> and the point (4, -3) → <em>x = 4, y = -3</em>.

Substitute to the equation:

-3=(-1)(4)+b

-3=-4+b   <em>add 4 to both sides</em>

-3+4=-4+4+b

1=b\to b=1

ICE Princess25 [194]

Answer: 3 : 37

Step-by-step explanation:

The shop sold 240 necklaces in a month.

Out of these, 18 were sold online.

The number that was sold offline was therefore:

= 240 - 18

= 222 shop sales

The ratio of  online sales to shop sales is therefore:

18 : 222

Take it to simplest form by dividing both sides by their highest common factor of 6:

3 : 37

Answer:

1. m<T =72 , m<U =54

2. EF= 18 in. , m<F=134'

3. x=4

Step-by-step explanation:

1. <s=<u , there is 180' in a triangle total so 180- <S - <U = <T

180 - 54 - 54 = 72

2. ef = gf

180 - 23 - 23 = 134

3. since bottom 2 angles are = , the 2 sides are also =

The length of a rectangle is 3 inches more than its width. the area of the rectangle is 40 square inches. what is the length, in
IceJOKER [234]
Since width is the smaller value, set width=x. That wold mean that length=x+3. Since Area=width*length, 40=x(3+x). Distribute the x to give you 40=3x+x^2. Set the equation equal to 0 giving you x^2+3x-40=0. Factor the equation to give you (x+8)(x-5)=0. Set each factor equal to 0. x+8=0 gives you x=-8 & x=-5 gives you x=5. Since we're working with lengths of objects, it can't be negative. Therefore, your width is 5. To find length, substitute width into the original expression (x+3). Therefore, length is 5+3=8.
