Find the equation of the line that has a slope of 1 and passes through the point (-2,11).

Lyrx [107]

Point-slope form is y-y1=m(x-x1)

m=1
y1=11
x1=-2

y-11=1(x-(-2)

In 2010 the population of Brazil was about 1.907×10 to the 8 power. The population of Mexico is about 1.123×10 to the 8 power. A

Romashka [77]

Brazil population: 1.907× $10^{8}$

Mexico population 1.123× $10^{8}$

To find how much more the population was in Brazil than in mexico, you would subtract the Brazil population to Mexico's population:

The $10^{8}$ 's would not cancel out because they are representing further decimal places that aren't written, so you would subtract 1.907 and 1.123.

1.907 - 1.123= 0.784 $10^{8}$

Brazil's population is 0.784× $10^{8}$ larger than Mexico.

The ____ of Powers property allows you to rewrite xa· xb as xa + b.

erica [24]

Answer:

The Product of Powers property allows you to rewrite $x^a\times x^b=x^{a+b}$ .

Step-by-step explanation:

We are given that,

The property allows us to write, $x^a\times x^b=x^{a+b}$

It is required to know the corresponding property.

As, we see that,

<em>The expression involves the product of terms having same base resulting in the addition of the powers.</em>

So, we have that,

The corresponding property is 'Product of Powers'.

Hence, the complete statement is,

The Product of Powers property allows you to rewrite $x^a\times x^b=x^{a+b}$ .

what is the general form of the equation of a circle with its Center at -2 1 and passing through -4 one

blondinia [14]

Answer:

$\large\boxed{x^2+y^2+4x-2y+1=0}$

Step-by-step explanation:

The standard form of an equation of a circle:

$(x-h)^2+(y-k)^2=r^2$

(h, k) - center

r - radius

The general form of an equation of a circle:

$x^2+y^2+Dx+Ey+F=0$

We have the center (-2, 1). Substitute to the equation in the standard form:

$(x-(-2))^2+(y-1)^2=r^2\\\\(x+2)^2+(y-1)^2=r^2$

Put thr coordinates of the point (-4, 1) to the equation and calculate a radius:

$(-4+2)^2+(1-1)^2=r^2\\\\r^2=(-2)^2+0^2\\\\r^2=4$

Therefore we have the equation:

$(x+2)^2+(y-1)^2=4$

Convert to the general form.

Use $(a\pm b)^2=a^2\pm 2ab+b^2$

$(x+2)^2+(y-1)^2=4\\\\x^2+2(x)(2)+2^2+y^2-2(y)(1)+1^2=4\\\\x^2+4x+4+y^2-2y+1=4\qquad\text{subtract 4 from both sides}\\\\x^2+y^2+4x-2y+1=0$
