If x(x - 5) = 14, then what is x equal to

Artyom0805 [142]

Answer:

x(x-5) = 14

x^2-5x-14 = 0

x^2 -7x+2x-14=0

x(x-7)+2(x-7)=0

(x+2)(x-7)=0

x = -2, 7

Hope this helps!

A curve passes through the point ????0, 5???? and has the property that the slope of the curve at every point P is twice the y-c

Angelina_Jolie [31]

Answer: $y=2x^2$

Step-by-step explanation:

Given Curve passes through $\left ( 0,5\right )$

Also the slope of the curve at every point p is twice the Y-coordinate of p

Let the coordinate of p be $\left ( x,y\right )$

Therefore

$\frac{\mathrm{d} y}{\mathrm{d} x}=2y$

$\frac{dy}{y}=2dx$

Integrating both sides

$\int \frac{dy}{y}=\int 2dx$

$\ln y=2x+c$

Substituting values

$\ln 5=c$

$\ln \frac{y}{5}=2x$

$y=2x^2$

Ingrid claims that Cosine (negative StartFraction pi over 2 EndFraction + y) = sine (y). Review Ingrid’s steps in verifying her

natali 33 [55]

9514 1404 393

Answer:

(b) Ingrid’s claim is correct, but her steps are incorrect

Step-by-step explanation:

As nearly as we can tell from the problem statement, Ingrid's table looks like the one attache. We have highlighted the incorrect steps.

Step 3 should read ...

0·cos(y) -(-1)·sin(y) = sin(y) . . . . . . . . . sin(-π/2) = -1

Step 4 should read ...

0 + sin(y) = sin(y)

So, Ingrid's conclusion is correct, but her steps are incorrect.
