I'm pretty there's a complement
suck it
3 - (7a + 1) =
3 - 7a - 1 =
-7a + 2 <===
If a number's ten digit is 
and the units digit is 
, then you can write the number as 
.
Obviously, inverting the digits would lead to the number 
.
Since this new number is 36 less than the original, we have
Since we also know that the digit in the tens place is three times that in the units place, we can add an equation to form a system:
And thus 
Answer:
The square root of 7 is 2.65
Step-by-step explanation:
2.645751311 is the long square root of 7 so just round it to the nearest tenth
I hope this helped in any way!
Plz mark brainliest :D
Since slope-intercept form is y = mx + b where m is slope and b is the y-intercept, so to find what the equation of the line is, you need to find the values of both variables.
The equation for slope is (change in y)/(change in x), or y/x.
You can set up the equation like this;
[tex] m= \frac{y2-y1}{x2-x1}\\
m=\frac{10-5}{2-(-3)} \\
m=\frac{5}{2+3}\\
m=\frac{5}{5}
m=1 [tex]
So the slope of the line is 1.
To find the y-intercept, solve y = (1)x + b for b;
[tex] y=x+b\\
b=y-x [tex]
Plug the values of a point in for x and y;
[tex] b=10-2\\
b=8 [tex]
This brings your final equation to be [tex] y=x+8 [tex].
