9 tens because 10 time 9 is 90 and 2 ones
Answer:
y=4x+19
Step-by-step explanation:
(-5,-1)
-1=4(-5)+b Multiply 4 and -5
-1=-20+b Add 20 to -1
19=b
b=19

should be : 24 + 6 = 6(4 + 1)
By graphing the given points, you will see that a rectangle can be made from the points. Points A and B lie on the same line horizontally as well as points C and D. To determine the distance between points, we use the distance formula expressed as:
d = √((y2-y1)^2 + (x2-x1)^2)
For points A and B, the term (y2-y1)^2 is equal to zero since they lie on the x-axis. The formula would become
d = √(x2-x1)^2
d = x2-x1 = a - 0 = a
Therefore, the distance would be equal to the value of a.
<span>1. Solve the system by substitution -2x+y=-11, 3x-4y=11.
</span>-2x+y=-11<span>
y = 2x-11
</span><span>3x-4y=11
</span>3x-4(2x-11)=11
3x -8x + 44 = 11
-5x = -33
<span>x =33/5
y = 11/5
</span><span>2. Solve the system using elimination- 2x+6y=-12, 5x-5y=10.
</span><span>(-2x+6y=-12)5
</span>-10x + 30y = -60
<span>(5x-5y=10)2
</span>10x - 10y = 20
Adding the two equations,
<span>-10x + 30y = -60
</span><span>10x - 10y = 20
</span>
20y = -40
y = -2
x = 0
<span>3. What is the solution of the following system?-3x-2y=-12, 9x+6y=-9.
</span><span>-3x-2y=-12
</span>y = -3/2 x + 6
<span>9x+6y=-9
</span>y = -3/2 x - 3/2
Since the slopes are equal then they are parallel lines so they never meet at one point.
