Write an equation of a line that passes through (-1,6) and has a slope of 4.
jeka94

Answer:

y-6=4(x+1) or y=4x+10

Step-by-step explanation:

Point: (-1,6)

m=4

Slope-point form is y-y1=m(x-x1)

y1=6

x1=-1

Now, plug it in!

y-6=4(x-(-1)) which is y-6=4(x+1)

Of course, if you want you could always simplify it down to y=4x+10 if you wanted to

Hope this helps!

Simply. If the solution is not a real number enter not a real number rotate picture answer all 3 please
yuradex [85]

Answer:

13. \frac{\sqrt[5]{x^4} }{x}.

14. v = \pm3\sqrt{5}

15. 2.

Step-by-step explanation:

13. x^{1/5} * x^{-2/5}

= x^{1/5 + (-2/5)}

= x^{1/5 - 2/5}

= x^{-1/5}

= \frac{1}{x^{1/5}}

= \frac{x^{4/5}}{x^{1/5 + 4/5}}

= \frac{x^{4/5}}{x}

= \frac{\sqrt[5]{x^4} }{x}.

14. v^2 - 45 = 0

v^2 = 45

\sqrt{v^2} = \pm\sqrt{45}

\sqrt{v^2} = \pm\sqrt{3^2 * 5}

v = \pm3\sqrt{5}.

15. \sqrt[3]{2} * \sqrt[3]{4}

= \sqrt[3]{2 * 4}

= \sqrt[3]{2 * 2 * 2}

= \sqrt[3]{2 ^3}

= 2.

Hope this helps!

The graph of a quadratic relationship is in the shape of a parabola. Parabolas are symmetric arcs and are useful for modeling re
zhuklara [117]

Answer:

  • The arcs on the Golden Gate Bridge.

Explanation:

I think about the Golden Gate Bridge, which is a suspension bridge.

As in any suspension bridge, a long cable is supported by two large supports.

The cable falls from a support, in the form of a curve concave upwards, to a minimum point that is the vertex of the<em> parabola</em>, through which the axis of <em>symmetry</em> passes, and curves again upwards to ascend to the upper end of the other support.

As a <em>unique feature</em> of this parabolic arc you can tell that the the concavity is upward; the parabola open upward.

Also, you can tell that the parabola is vertical, which means that the axis of symmetry is vertical.

The <em>symmetry</em> is clear because to the curve to the left of the vertex is a mirror image of the curve to the right of the vertex.
