If x = ─7 and y= 3 , find i) x+y ii) xy iii) xꓥ2 + yꓥ2 WHAT IS THE ANSWER
Answer:
Step-by-step explanation:
1. X + y
Putting values of x and y
-7 + (-3)
= - 10
2. xy
Putting values of x and y
(-7)(-3)
= 21
3. x2 + y2
Putting values of x and y
= (-7)2 + (-3)2
= 49 + 9
= 58
An airplane flies at an altitude of 14,690 feet while a submarine is submerged at a depth of 521 feet below the surface of the ocean. What is the difference between these two elevations?
Answer:
15,211 feet
Step-by-step explanation:
According to the question, given data are as follows:
Airplane altitude = 14,690 feet above
Submarine depth = 521 feet below
So, let the difference between these two elevation be d,
So, we can calculate difference by using following formula:
Difference = Airplane altitude + Submarine depth
By putting the value, we get
Difference = 14,690 + 521
= 15,211 feet
Find the slope of the ordered pairs (2,5) (4,13)
Answer:
[tex]slope = \frac{y2 - y1}{x2 - x1} \\ slope = \frac{13 - 5}{4 - 2} \\ = \frac{8}{2} = 4[/tex]

Find the increasing functions. Then arrange the increasing functions in order from least to greatest rate of change. (not all of the functions will be used)
y= 5/2x + 10
y= -1/2x + 1/2
y= 3/2x - 11/2
y= 1/2x - 2
y= 4/3x - 7/3
y=3/4x - 10
Answer:
to a function is increasing we have to find the slope of the function
the higher the slope the faster the growth
Step-by-step explanation:
slope = 5/2. which is 2.5slope 2 = -1/2 which is -0.5slope 3 = 3/2 which is 1.5slope 4 = 1/2 which is 0.5slope 5= 4/3 which is 1.33slope 6 = 3/4 which is 0.75so the function in increasing order
y= -1/2x + 1/2
y= 1/2x - 2
y=3/4x - 10
y=4/3x -7/3
y=3/2x-11/2
y=5/2x +10

Given the table, how can you use a graph to find additional equivalent ratios? x y 2 3 4 6 Plot the ordered pairs (2, 3) and (4, 6). Start at (4, 6). Move right 3 and up 2, and then plot a point. Keep this same rate to get other points. Draw a line through the two given points. Any point below the line represents an equivalent ratio. Plot the ordered pairs (2, 4) and (3, 6). Start at (3, 6). Move right 2 and up 3, and then plot a point. Keep this same rate to get other points. Draw a line through the two given points. Any point on the line represents an equivalent ratio.

find the value of x in the triangle below
Answer:
x=109
Step-by-step explanation:
The angles inside of a triangle all add up to 180 degrees. So:
23+48+x=180
Simplify Like-Terms:
71+x=180
Subtract 71 from both sides:
x=109

Mya and ERIC WORK IN A BAKERY . MYA HAS 3 TIMEA AS MUCH FLOUR AS ERIC .MYA HAS 15.81LB OF FLOUR .USE THE EQUATION 3F = 15.81 TO FIND HOW MUCH FLOUR ERIC HAS .
Answer:
5.27 lb
Step-by-step explanation:
Given that,
Mya has 3 times as much floor as Eric. Mya has 15.81 lb of floor. The relation is given by :
Let Eric has F floor.
3F = 15.81 ...(1)
We need to find how much flour Eric has.
Dividing both sides by 15.81.
F = 15.81/3
F = 5.27 lb
Hence, Eric has 5.27 lb of flour.

Work out the area of the trapezium ABDE.
9 cm
6 cm
Answer:DE = 4
AB = 30
Step-by-step explanation:
Answer:
30cm²
Step-by-step explanation:
AE/BD = CE/CD
9/6 = CE/8
CE = 9/6 x 8
CE = 12cm
DE = CE - CD
DE = 12 - 8 = 4 cm
½(6 + 9)4 = 30cm²
