The two numbers are 22 and 7.
22 + 7 = 29
22 - 7 = 15
here is how we can find these numbers;
let a and b are two numbers
a + b = 29
a - b = 15
a = 15 + b
now put this value of a in any of the equation
a + b = 29
15 + b + b = 29
15 + 2b = 29
2b = 29 - 15
2b = 14
b = 7
now put the value of b to find the value of a;
a = 15 + b = 15 + 7 = 22
a = 22
-7 it’s closer to -7 than -6.5
The system has:
- No solutions for two parallel lines.
- 1 solution for two nonparallel lines.
- Infinite solutions for two equations that describe the same line.
<h3>How to identify the number of solutions for the systems?</h3>
A system of two linear equations is given by:
y = a*x + b
y = c*x + d
1) The system has no solutions when both lines are parallel lines, this happens when both lines have the same slope and different y-intercept.
y = a*x + b
y = a*x + d
2) The system has one solution when the lines have different slopes:
y = a*x + b
y = c*x + d
3) The system has infinite solutions when both equations describe the same line:
y = a*x + b
y = a*x + b

Answer:
31 in sq
Step-by-step explanation:
The interior shape is inside the exterior shape
first get the area of the big shape
9 times 15 = 135 in sq
now get the area of the interior shape:
8 times 13 = 104 in sq
now subtract interior shape from exterior
135 - 104 = 31 in sq
that's the shaded part
Answer:
1/169
Step-by-step explanation:
The probability of drawing a 3 in a 52 card deck is 4/52 which can be simplified to 1/13.
The probability of then drawing a jack is 4/52, also simplified to 1/13. It doesn't matter of you want to put jack or 3 first, there are 4 of each in a deck.
1/13*1/13=1/169
