Question 1)

Given

The expression is 5xy

To determine

Find the value of 5xy if x = 2 and y = 3

5xy

substitute x = 2 and y = 3

5xy = 5(2)(3)

= 5(6)

= 30

Therefore, the value of 5xy = 30 if x = 2 and y = 3.

Note: your remaining questions are not mentioned. But, the procedure may remain the same. Hopefully, your concept will be cleared anyway.

Find the slope of the line that passes

Vlad1618 [11]

Answer:

a) $\frac{4}{3}$

b) -1

Step-by-step explanation:

$\boxed{slope = \frac{y1 - y2}{x1 - x2} }$

where (x₁, y₁) is the first point and (x₂, y₂) is the second point

6a) Slope

$= \frac{7 - 3}{4 - 1}$

$= \frac{4}{ 3}$

6b) Slope

$= \frac{6 - 5}{2 - 3}$

$= \frac{1}{ - 1}$

= -1

Write two numbers that when rounded to the greatest place value have an estimated sum of 11,000 and an estimated difference of 3

lianna [129]

Answer:

x + y = 10,999.5 (rounded up to 11000)

x - y = 3,000.3 (this would be rounded down to 3000)

Step-by-step explanation:

Assume;

Two numbers are x, y

So,

x + y = 11,000 .......eq1

x - y = 3,000 .........eq2

eq1 + eq2

So,

2x =14,000

x = 7,000

So y = 4,000

For rounding number

x = 6,999.9 (rounded up to 7,000)

y = 3,999.6 (rounded up to 4,000)

Sum;

x + y = 10999.5 (rounded up to 11000)

x - y = 3000.3 (this would be rounded down to 3000)
