Answer:

x^2 -11x +30 = 0

Step-by-step explanation:

If these two integers are solutions of the quadratic, then its factors are ...

(x -5)(x -6) = 0

Multiplying this out, we get ...

x^2 -11x +30 = 0

What is the slope-intercept equation of this line?

Gekata [30.6K]

Answer:

y = -2x+8

Step-by-step explanation:

We have 2 points so we can find the slope

m = (y2-y1)/x2-x1)

m = ( -4 -8)/(6 - 0)

= -12/6

= -2

The y intercept is 8 from the point (0,8)

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = -2x+8

If you vertically stretch the exponential function f(x)=2^x by a factor of 3, what is the equation of the new function

AleksAgata [21]

Answer:

$y=3*2^{x}$

Step-by-step explanation:

A vertical stretch of a function means the output values have changed by a factor of 3 or multiplication by 3. Recall, an exponential function has the basic form

$y=ab^{2}$ .

If our equation is $f(x)=2^x$ , then a=1. To stretch it vertically by a factor of 3, we multiply a by 3. So 1(3)=3. The value of a now becomes 3.

$y=3*2^{x}$

Help me please fast

Natalija [7]

Answer:

Step-by-step explanation:

$\frac{5}{x-3}+\frac{2}{x+1}=3 \\\\\frac{5(x+1)+2(x-3)}{(x-3)(x+1)} =3\\\\5x+5+2x-6=3(x-3)(x+1)\\\\7x-1=3(x^2+x-3x-3)\\\\7x-1=3(x^2-2x-3)\\\\7x-1=3x^2-6x-9\\\\0=3x^2-6x-7x-9+1\\0=3x^2-13x-8$

Hence proved!
