Answer:

y=2x-3

Step-by-step explanation:

So we want to find an equation in slope-intercept form that is parallel to:

y=2x+5

And contains the point (4,5).

So to create the equation, we will need to slope and the y-intercept.

First, recall that parallel lines have the same slope. Since we want our equation to be parallel to y=2x+5, this means that the slope of the new equation must be 2.

Now, we can use the point-slope form to solve for the y-intercept. The point slope form is:

y-y_1=m(x-x_1)

Let (4,5) be x₁ and y₁. m is 2 since it's parallel to y=2x+5. Thus:

y-5=2(x-4)\\

Distribute:

y-5=2x-8

Add 5 to both sides:

y=2x-3

And that's our equation :)

This is super simple. Begin with cross multiplying


35/x=7/13 becomes (35)*(13)=(7) *(x)

Then multiply my love muffin, you get...

455=7x

divide both sides by 7

65=x
-or-
x=65

hope that helped :)

Which of the following is equivalent to<br> (5) 3<br> O 54<br> O 54<br> 05<br> O V5
IrinaK [193]

Answer:

D. \sqrt[3]{5^7}

Step-by-step explanation:

The formula for this conversion is:

a^\frac{x}{n}=\sqrt[n]{a^x}

Substitute the values you currently have.

5^\frac{7}{3}=\sqrt[n]{a^x}

Since we know that

a = 5

x = 7

n = 3

Fill the square root with this.

5^\frac{7}{3}=\sqrt[3]{5^7}
