Answer

x²+15x+50

Step-by-step explanation:

You start with the left side of the equation. Multiply the right binomial by x

{ x (x) + x(10) }  = x² + 10x

Then multiply the right side of the equation by 5

{  5 (x) + 5 (10)  =  5x + 50

Add both the (x² + 10x) and the (5x+50)

This will give you an answer of x²+15x+50

Answer: x^2+10x+5x+50    =    x^2+15x+50

Step-by-step explanation:

Basically, use something called FOIL. It stands for first, outer, inner, last. Basically multiply the first x, by the first x in the second parenthesis. Then multiply that x by the outer x in the second parenthesis. After that, multiply the 5 by the inner x. Then the five by the ten.

To answer this question, try to solve the system of equations.  Start by plugging in "x^{2} +3x-7" in for y in the second equation:

x^{2} +3x-7-5x+8=0

<em>*Combine like terms*</em>

x^{2} -2x+1=0

<em>*Factor*</em>

(x-1)(x-1)=0

<em>*Set each term equal to 0*</em>

x-1=0

<em>*Add 1 to both sides*</em>

x=1


C) There is exactly 1 solution.


Hope this helps!!

Suppose you need to know an equation of the tangent plane to a surface S at the point P(4, 1, 4). You don't have an equation for
Alex777 [14]

Answer:

15x-8y+9z=88

Step-by-step explanation:

We are given that

Equation of curves

r_1(t)=

r_2(u)=

Both curves lie on S.

We have to find the equation of tangent plane at P(4,1,4).

r'_1(t)=,r'_2(u)=

r_1(0)=, r_2(1)=

Hence, t=0 and u then it satisfied the given point.

Substitute the values in the derivatives

r'_1(0)=,r'_2(1)=

r'_1(0)\times r'_2(1)=\times =

The equation of tangent at point P(4,1,4) is given by

30(x-4)-16(y-1)+18(z-4)=0

30x-120-16y+16+18z-72=0

30x-16y+18z=176

15x-8y+9z=88

9. The decrease in population for Lakeside 5,500.

You can find this by taking the new amount and subtracting the original amount. This will give you the net change.

new - old = net change

45,800 - 51,300 = net change

-5,500 = net change

10. The percent increase for Riverview is +51%.

You can find that by looking at the formula for percent change.

\frac{new - old}{old}

\frac{63000 - 41700}{41700}

\frac{21300}{41700}

51%
