Answer: X= days. Equation: 16-2-3X=X

Step-by-step explanation:

there is none, it’s pretty straight forward.

But if you want to solve for how many days then it’s, 3 1/2 days

Find the number if:

Paraphin [41]

Answer:

162 and $\frac{5}{2}$

Step-by-step explanation:

To find the original number multiply by the reciprocal of the multiplier, that is

90 × $\frac{9}{5}$ = $\frac{810}{5}$ = 162

------------------------------------------------------------------------

Similarly

Change the mixed number into an improper fraction

5 $\frac{5}{6}$ = $\frac{35}{6}$ , then

$\frac{35}{6}$ × $\frac{3}{7}$ ( cancel 35 and 7 by 7 / cancel 6 and 3 by 3 )

= $\frac{5}{2}$ × $\frac{1}{1}$

= $\frac{5}{2}$

In f(x) = 2x2 − 8x − 10, the y-intercept is ? at ? and the x-intercepts are (-1, 0) and ? .

IgorLugansk [536]

<h2>1. y-intercept</h2>

$\boxed{(0,-10)}$

The quadratic function $f(x)=2x^22-8x-10$ represents a parabola. In fact, the graph of a quadratic function is a special type of U-shaped curve called a parabola. To find the y intercept, we set $x=0$ as follows:

$f(x)=2x^2-8x-10 \\ \\ If \ x=0 \rightarrow f(0)=-10 \\ \\ Then \ y-intercept: \\ \\ (0,-10)$

<h2>2. x-intercepts</h2>

$\boxed{(-1,0) \ and \ (5,0)}$

To find the other x-intercept, we must set $y=0$ as follows:

$f(x)=2x^2-8x-10 \\ \\ If \ y=0 \rightarrow 2x^2-8x-10=0 \\ \\ Using \ the \ quadratic \ formula: \\ \\ x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \\ \\ \therefore x=\frac{-(-8) \pm \sqrt{(-b)^2-4(2)(-10)}}{2(2)} \\ \\ \therefore x_{1}=-1 \ and \ x_{2}=5$

Therefore, the other x-intercept is $(5,0)$ . You can see both the y-intercept and the x-intercepts in the figure below.
