Answer:
The solution of the system of equation is x = 3.5
Step-by-step explanation:
The given system of equation is;
f(x) = 3·x + 5 and g(x) = x + 12
To find the common solution, we equate the values of both functions as follows;
3·x + 5 = x + 12
We collect like terms;
3·x - x = 12 - 5
2·x = 7
x = 7/2 = 3.5
x = 3.5
Therefore, the solution of the system of equation is x = 3.5

measure the angle of 10x+10
Answer:
We know that opposite angle are congruent.
[tex]10x + 10 = 11x + 3 \\ \\ 10x - 11x = - 7 \\ - x = - 7 \\ x = 7[/tex]
So, We found out that x = 7,
So, Putting x = 7 in 10x+10
[tex]10 \times 7 + 10 \\ \\ = 70 + 10 \\ \\ = 80[/tex]
So, The measure of angle 10x+10 is 80.
Solve r9+1= 0 please help idk what it means or anything really
Answer:
r = -1
Step-by-step explanation:
This is the answer because:
1) You can take the root of both sides and solve
2) You can also isolate the variable and solve for it
1. r9 + 1 = 0, divide 9 and 0 first. 9 x 0 = 0
2. r + 1 = 0, subtract 0 and 1. 0 - 1 = -1

The equation of line j is
y= -6/7+7. Line k is perpendicular to j. What is the slope of line K
Answer:
7/6
Step-by-step explanation:
in order for it to perpendicular then its need to be the negative reciprocal of it, so you flip the sign making it positive and do the opposite of the slope like for ex if it was 1/2 it would have been 2

-2x – 6y = -24
X-8y = -10
Answer:
{x,y}={31,4}
Step-by-step explanation:
x-8y = -1 x-6y = 7
Answer:
first we find the value of 'y' so
x-8y=-10+8y
x=-10+8y
-2(-10+8y)-6y=-24
20-16y-6y=-24
20-22y=-24-20
-22y=-44
y=2
then also we can find the value of 'x'
-2x-6y=-24
2x-6(2)=-24
2x-12= -24
2x= -24+12
x= -12
If x = 10 find the value of
2x + 9
Answer:
29
Step-by-step explanation:
okay so we are going to substitute 10 where the x variable is in this problem
2x + 9
like this:
2(10) + 9
and then we do order of operations by multiplying 2 by 10 then adding 9:
2x + 9 =
2(10) + 9 =
20 + 9 =

123 degrees
3x degrees
Answer:
Step-by-step explanationthe answer is 19 because your trying to find 180 and your timing that 3 by what ever gets you the extra of 180 so you do 19 ×3 equaling 57 and then you add in that 123 and it all equals 180
The value of x is 19°.
What are linear pairs?A linear pair of angles are formed when two lines intersect each other at a single point.
Given a pair of angles which are on a straight line and so, making a linear pair,
123°+3x=180°
3x = 57°
x = 19°
Hence, x = 19°

Help me please with math
Answer:
The average rate will be: 0.7 inches/hour
Hence, Option (4) is correct.
Step-by-step explanation:
As the average rate = change in y-values/change in x values
= Δy/Δx
From the table, it is clear that over the time interval 't=2' to 't=7', the values
snow depth 'd' inches change from d=1.5 to d=5.
Therefore,
Average rate = Δy/Δx
= (5-1.5) / (7-2)
= 3.5/5
= 0.7 inches/hour
Therefore, the average rate will be: 0.7 inches/hour
Hence, Option (4) is correct.
