Slope of 2 and passes through the point (-4,3). Write the equation in slope intercept form
erastova [34]

Answer:

The equation is y = 2x + 11.

Step-by-step explanation:

It is given that the gradient of the equation is 2. Using slope-form formula, y = mx+b where m is gradient and b is y-intercept. In order to find b, you have to substitute x-coordinate and y-coordinate into the equation :

y = mx + b

m = 2

At(-4,3),

3 = 2(-4) + b

b = 3 - 2(-4)

= 11

Clara Schumann is buying bagels for her coworkers, She buys a dozen bagels priced at $5.49 a dozen. The bakery's cost for making
Tcecarenko [31]

Answer:

The markup rate is 144% .

Step-by-step explanation:

Formula

Mark\ up\ percentage = \frac{(Selling\ price-Cost\ price)\times 100}{Cost\ price}

As given

Clara Schumann is buying bagels for her coworkers, She buys a dozen bagels priced at $5.49 a dozen.

i.e

Selling price of a dozen bagels is $5.49 .

The bakery's cost for making the bagels is $2.25 per dozen.

i.e

Cost price of a dozen bagels is $2.25 .

Putting all the values in the formula

Mark\ up\ percentage = \frac{(5.49-2.25)\times 100}{2.25}

Mark\ up\ percentage = \frac{3.24\times 100}{2.25}

Mark\ up\ percentage = \frac{32400\times 100}{225\times 100}

Mark\ up\ percentage = \frac{32400}{225}

Markup percentage = 144 %

Therefore the markup percentage is 144% .

Which craftworld should I choose to colect for Warhammer 9th edition:
g100num [7]

Answer:

Ulthwé was caught in the pull of the Eye of Terror, where the Immaterium intersects with realspace. It is a breeding ground for Chaos and a gateway into the Warp. Due to this baleful proximity to the Eye, Ulthwé must be on constant high alert in case of attacks by the Forces of Chaos. Constant risk and warfare has hardened this Craftworld's citizens to hardship. Due to the lack of Aspect Warriors on the Craftworld, Ulthwé maintains a standing militia known as the Black Guardians, who are more skilled and better-trained than the Guardians of other Craftworlds.Step-by-step explanation:
