$n^2 -7=38$

$n^2=38+7$ $Add \ 7 \ to \ both \ sides$

$
n^2=45
 
$

$n=+ \sqrt{45}$

$n=+3 \sqrt{5}$

what does y =mx +b mean and how do you use it to solve problems? whats the different between y=mx+b and y=mx + c

algol13

y=mx+c is the equation for a line graph, m is the gradient and c is where it goes through the y axis, the only difference between y=mx+c and y=mx+b is where u live as in different countries learn it different ways but it is still the same thing

-3r-8(8r+8)=-9(-4+9r)

natulia [17]

Answer:

r= 7.14 (rounded to 2 decimal places)

Step-by-step explanation:

We have to solve this equation for the value of r. We will use distributive property and basic algebra to solve this.

Distributive property is a(b+c) = ab + ac

Now, the steps of solving are shown below:

$-3r-8(8r+8)=-9(-4+9r)\\-3r -64r-64=36-81r\\-67r-64=36-81r\\-67r+81r=36+64\\14r=100\\r=\frac{100}{14}\\r=7.14$

Hence, value of r is 7.14 (rounded to 2 decimal places)
