Step-by-step explanation:

The student is viewing the equation in the wrong way, he needs to put the equation in standard from / correctly first in order to be able to find the slope.
The straight line formula is

$y = mx + c$

looking at the formula in that form m=gradient (slope) , and c is the Y intercept.
so putting the above equation in the correct form

$y = - 4x + 3$

so m = -4 meaning that -4 is the gradient aka slope, and 3 is the y-intercept!
hope this helps

9. A home improvement store advertises 60 square

vlada-n [284]

Answer:

C. $5.55

Step-by-step explanation:

Total cost of installing 60 square feet of flooring

= $253.00 + $80

= $333

Total number of square feet for flooring = 60

Now cost per square foot of the flooring

= total cost/total number of square feet

That’s

$333/60 = $5.55

Each square foot cost $5.55

A hairdresser is deciding where to open her own studio. If the hairdresser chooses Location A, she will pay $1200 per month in r

Ymorist [56]

She will need to cut 26.6 haircuts a month a location A to break even (1200/45 = 26.6) so roughly 27 haircuts to make a profit

She will need to cut 30 haircuts at location B to break even (1800/60 = 30) and 31 hair cuts to see a profit.

She will need to cut 30.67 haircuts at location A and 33 haircuts at location B to make the same profit at either location (Roughly $180).

30.67 x 45 = 1380.15 - 1200 = 180

33 x 60 = 1980 - 1800 = 180

The number of letters in Stephanie's full name is sixteen less than twice the number of letters in Amy's full name. If the numbe

Anestetic [448]

Answer:

19 letters

Step-by-step explanation:

Suppose Number of Amy's full name letters = X

Number of Stephanie's full name letters = Y

Now, according to given condition that ''number of letters in Stephanie's full name is sixteen less than twice the number of letters in Amy's full name'',

Equation 1 becomes

Y = 2X-16

Now, according to second condition, product of their names' letter is 418. So,

Equation 2 becomes

XY = 418

Deducing value of X from equation 1,

X = (Y+16)/2

Putting this value in equation 2 we get,

{(Y+16)/2}*Y = 418,

By simplifying this equation we get a quadritic equation

(Y^2)+16Y-836=0

By breaking middle term (You can use quadratic formula here as well)

(Y^2)+38Y-22Y-836=0

Y(Y+38)-22(Y+38)=0

(Y-22)(Y+38)=0

At this stage we have two values for Y,

Y=22, or Y=-38

Now considering only positive value since the number of letters in a name can not be in negative number,

Y=22,

So X=(Y+16)/2

X=19
