Which equation is the slope intercept form of this equation?

solmaris [256]

Answer:

Step-by-step explanation:

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

$y=mx+b$

m - slope

b - y-intercept

We have the equation i point-slope form.

Convert to the slope-intercept form:

$y-4=-2(x-5)$ use the distributive property

$y-4=-2x+(-2)(-5)$

$y-4=-2x+10$ add 4 t oboth sides

$y-4+4=-2x+10+4\\\\y=-2x+14$

The living spaces of all homes in a city have a mean of 2300 square feet and a standard deviation of 500 square feet. Let x be t

antoniya [11.8K]

Answer:

the mean and standard deviation is 2300 and 100 respectively

Step-by-step explanation:

Given that

Mean = 2300

Standard deviation = 500

let us assume the x be the mean of living space

And, the sample is of 25 homes

We need to find out the mean and the standard deviation

So here mean = 2300

And, the standard deviation

= 500 ÷√25

= 500 ÷ 5

= 100

hence, the mean and standard deviation is 2300 and 100 respectively

The gradient of the curve

AleksAgata [21]

Answer:

Coordinate of P is (-2, -3)

Step-by-step explanation:

Gradient is the derivative of the curve:

$y = {3x}^{2} + 11x + 7 \\ \\ \frac{dy}{dx} = 6x + 11$

but dy/dx is -1 :

$6x + 11 = - 1 \\ 6x = - 12 \\ x = - 2$

substitute for x :

$y = 3( - 2) {}^{2} + 11( - 2) + 7 \\ y = - 3$
