Factor the quadratic expression to reveal the zeroes of the function it defines
Kazeer [188]

Answer:

Below.

Step-by-step explanation:

This factors to the product of 2 binomials like (x + a)(x + b), where a and b are 2 numbers.

40 = 4 * 10 and 14 = 4 + 10 so the answer is

(x + 4)(x + 10).

If we expand this we will get back to the quadratic expression:

(x + 4)(x + 10)

= x(x + 10) + 4(x + 10)

= x^2 + 10x + 4x + 40

= x^2 + 14x + 40.

4y+4=7z, 36-4y=3x <br> thank you so much!!
iogann1982 [59]
Is it supposed to say 7x rather than Z? If so then


If you make both equations = to 4y you can work out the answer so

4y =7x-4
4y = 36-3x

Then you put them equal to each other so

7x-4 = 36-3x
10x = 40
x = 4

You can then find y by doing
4y = 7x4 - 4
4y = 28-4
4y = 24
y= 6

So the answer is x = 4 and y = 6

How to create an equation for function m? I wrote the right equation as a guess, but I don't understand it.​
AfilCa [17]

Answer:

h(x)=2(x + 3)^{\frac{1}{2} }

Step-by-step explanation:

Parent function of the square root function has been given as,

f(x) = x^{\frac{1}{2} }

If the graph of the given function is stretched vertically by the scale factor = g(x) = k(x^\frac{1}{2})

If the graph is shifted 3 units to the left,

h(x) = k(x + 3)^{\frac{1}{2} }

Since, the graph of the function passes through a point (-2, 2),

2=k(-2 + 3)^\frac{1}{2}

2 = k

Therefore, the function is h(x)=2(x + 3)^{\frac{1}{2} }.
