Translate each equation into slope-intercept form. Then, state the slope and y-intercept . 4y=2x+20

likoan [24]

Answer:

The slope-intercept form of the equation: y = 0.5x + 5

The slope: m = 0.5

The y-intercept: b = 5

Step-by-step explanation:

Slope-intercept form is y = mx + b, where m is the slope and b is y-intecept

4y = 2x + 20 {divide both sides by 4}

y = 0.5x + 5 ⇒ m = 0.5 and b = 5

What is the focus of the parabola with equation y = x2?

hammer [34]

Answer:

$focus=(0,\frac{1}{4})$

Step-by-step explanation:

We are given equation of parabola as

$y=x^2$

we can also write as

$y=1(x-0)^2+0$

now, we can compare

$y=a(x-h)^2+k$

and find a , h , and k

a=1

h=0

k=0

now, we can use focus formula

$focus=(h,k+\frac{1}{4a})$

now, we can plug values

$focus=(0,0+\frac{1}{4\times 1})$

$focus=(0,\frac{1}{4})$

WILL GIVE BRAINLIEST!

expeople1 [14]

Answer:

$Average\:Rate\:Change=-59.4$

Step-by-step explanation:

The given function is $f(x)=120(0.1)^x$ .

We want to find the average rate of change of this function from $x=0$ to $x=2$ .

This is given by:

$Average\:Rate\:Change=\frac{f(2)-f(0)}{2-0}$

This implies that;

$Average\:Rate\:Change=\frac{120(0.1)^2-120(0.1)^0}{2-0}$

$Average\:Rate\:Change=\frac{120(0.1)^2-120}{2}$

$Average\:Rate\:Change=\frac{120((0.1)^2-1)}{2}$

$Average\:Rate\:Change=\frac{60(0.01-1)}{1}$

$Average\:Rate\:Change=60(-0.99)$

$Average\:Rate\:Change=-59.4$

Factors of 4x^3-14x^2+12x

IRISSAK [1]

Step-by-step explanation:

4x³ - 14x² + 12x

= 2x[2x² - 7x + 6]

= 2x[(2x-3)(x-2)]

= 2x(2x-3)(x-2)
