One factor of 7x2 + 33x – 10 is

stiv31 [10]

$7x^{2} +33x-10=0$

$\implies 7x^{2} +35x-2x-10=0\\\implies7x(x+5)-2(x+5)=0\\\implies (7x-2)(x+5)=0$

$7x - 2 = 0\\\implies \boxed{\bold{x = \frac{2}{7} }}$

$x+5=0\\\implies \boxed{\bold{x=-5}}$

Arisa [49]

Answer:

960

Step-by-step explanation:

<u>Given:</u>

Stan's cookie recipe makes 24 cookies.
It needs exactly 384 sprinkles.

Number of sprinkles needed for 60 cookies

<h2><u>Solution:</u></h2>

<u>Find the number of sprinkles needed for 1 cookie:</u>

24 cookies = 384 sprinkles
1 cookie = 384 ÷ 24
1 cookie = 16 sprinkles

<u>Find the number of sprinkles needed for 60 cookies:</u>

1 cookie = 16 sprinkles
60 cookies = 16 x 60
60 cookies = 960 sprinkles

Answer: Stan will need 960 sprinkles for 60 cookies.

For the function f(x)=-4sqrtx-1, find the inverse function.

d1i1m1o1n [39]

Given function: $f(x)=-4\sqrt{x}-1$ .

We need to find the inverse of the given function f(x).

Let us write the function in terms of x and y first.

$y=-4\sqrt{x}-1$

Now, in order to find the inverse, we need to switch x and y, we get

$x=-4\sqrt{y}-1$

Now, we need to solve it for y.

In order to solve it for y, we need to isolate it for y.

Adding 1 on both sides, we get

$x+1=-4\sqrt{y}-1+1$

$x+1=-4\sqrt{y}$

Dividing both sides by -4, we get

$\frac{x+1}{-4}=\sqrt{y}$

In order to get rid square root from right side, we need to square both side.

$(\frac{x+1}{-4})^2=(\sqrt{y})^2$

$\frac{(x+1)^2}{16}=y$

Or $y=\frac{1}{16}(x+1)^2$

Therefore, inverse function is

$f^{-1}(x)=\frac{1}{16}(x+1)^2$ .
