Answer:

-5/6 =x

Step-by-step explanation:

f(x) = -12x+7

We want to find x when f(x) = 17

17 = -12x+7

Subtract 7 from each side

17-7 = -12x +7-7

10 = -12x

Divide each side by 12

10/-12 = -12x/-12

-5/6 =x

Answer:

$\huge\boxed{x = -\frac{5}{6}}$

Step-by-step explanation:

$f(x) = -12x+7$

Given that f(x) = 17

$17 = -12x+7$

Subtracting 7 to both sides

$17-7 = -12x$

10 = -12 x

Dividing both sides by 12

$x = - \frac{10}{12}$

$x = -\frac{5}{6}$

Answer:

Acute and isosceles

I need to know the answer

almond37 [142]

Answer:

Step-by-step explanation:

That's the formula for the solution of a quadratic equation, like this:

$a {x}^{2} + bx + c = 0$

The formula is:

$x = \frac{ - b± \sqrt{ {b}^{2} \: - 4ac } }{2a}$

In your case:

$a = 7 \\ b = - 5 \\ c = - 2$

The only answer that has c = -2 is the first one, A.

If you move the 5 to the left-hand side, it becomes -5 and with the +3 gives a -2.

Answer:

3.56 cm

Step-by-step explanation:

<em>Cube</em> is a 3D closed structure in which each adjacent side is perpendicular to each other and every side is equal to each other.

Let the side of cube be $a$ cm.

Please refer to attached image of cube for a clear look and feel of a cube with each side = a units.

Then, volume of cube is given by the formula:

$V = a^3$

Here, we are given that:

$V = 45\ cm^3$

$\Rightarrow a^3 = 45\ cm^3\\\Rightarrow a =\sqrt[3] {45}\\\Rightarrow a ={45}^\frac{1}{3}\\\Rightarrow a = 3.56\ cm$

So, the answer is, Side of each petit four is, $a = 3.56\ cm$ .

mihalych1998 [28]

Answer:

Step-by-step explanation:

eq. of given line is x+y=10

eq. of any line parallel to given line is x+y=a

if it passes through (-1,5) then -1+5=a

or a=4

reqd. eq of line is x+y=4

or y=-x+4
