The sum of two numbers is 19, and their difference is 55. What are the two numbers?
Answer:
37 and -18
Step-by-step explanation:
Let one number be x and other y
1 x + 1 y = 19 .............1
1 x -1 y = 55 .............2
Eliminate y
multiply (1)by 1
Multiply (2) by 1
1 x 1 y = 19
1 x + -1 y = 55
Add the two equations
2 x = 74
/ 2
x = 37
plug value of x in (1)
1 x + 1 y = 19
37 + 1 y = 19
1 y = 19 -37
1 y = -18
y = -18
37 and -18

Using the information given, select the statement that can deduce the line segments to be parallel. If there are none, then select none. When m<7=m<8
AD || BC
AB || DC
none
Answer:
AB || DC

cause Well, since AB and DC arent touching anothers line, then that will be paralell because paralell is two or more lines that arent ever going to touch another line
Find the slope of the line passing through the points (-8,-8) and (6,-8)
Answer:
Slope = 0
So, the line is parallel to x-axis
Step-by-step explanation:
(x₁ , y₁) = (-8, -8) & (x₂ ,y₂) = (6 , -8)
[tex]Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\=\frac{-8-[-8]}{6-[-8]}\\\\=\frac{-8+8}{6+8}\\\\= 0[/tex]

what’s the answer??????
Answer:
53.99 cm
Step-by-step explanation:
- since we have the hypotenuse and want to find the opposite side to the angle, we use sin x = hypotenuse/ opposite
- sin (38) = 16/AB
- rearrange & calculate, AB = 16/sin(38) = 53.986
- we round it up to 53.99
(5x+3y)-(2x-7y)+8x please help
Answer:
A I soo sorry but I really can't solve this I have not learned it yet
Answer: 11x-10y
Step-by-step explanation:
Combine like terms.
(5x+3y)-(2x-7y)+8x
3x + 8x
Remember to distribute the negative.
-(-7y) = +7y
3y +7y
Combine like terms once again.
3x+8x= 11x and 3y+7y= 10y
