Answer:

4 plants

Explain how to find the product of the sum and difference of two terms. Give an example with your explanation.
hjlf
Given two terms a, b.
Sum of terms = a+b
Difference of terms = a-b
Product of sum and difference (do not forget parentheses)
=(a+b)(a-b)
which can be expanded as=a^2-b^2

We can make use of this property to calculate with lightning speed, assuming you know the squares of numbers.

For example,
8*6=(7+1)(7-1)=7^2-1^2=48
9*7=(8+1(8-1)=8^2-1^2=64-1=63
5*15 = (10+5)(10-5)=10^2-5^2=75
22*18=(20+2)(20-2)=20^2-2^2=400-4=396
63*57=(60+3)(60-3)=60^2-3^2=3600-9=3591
128*112=(120+8)(120-8)=120^2-8^2=14400-64=14336
We can go on and on!

Subtract the sum of 126 and (-747) from the sum of 135 and (-136)​
Karolina [17]
135 + (-136) = 135 - 136
= -1
126 + (-747) = -621

-1 - (-621) = -1 + 621 = 620

50 POINTS FOR CORRECT AWNSER!
Grace [21]

Answer:

\mathsf{y < \dfrac47x-4}

Step-by-step explanation:

<u>First, find the equation of the line</u>.

<em>Slope-intercept form</em> of a linear equation:  \mathsf{y=mx+b}

(where m is the slope and b is the y-intercept)

From inspection of the graph, the y-intercept is at (0, -4)

Therefore, b = -4

Choose another point on the line, e.g. (7, 0)

Now use the slope formula to find the slope:

\mathsf{slope=\dfrac{y_2-y_1}{x_2-x_1}}

where:

  • \mathsf{(x_1,y_1)=(0,-4)}
  • \mathsf{(x_2,y_2)=(7,0)}

\implies \mathsf{slope=\dfrac{0-(-4)}{7-0}=\dfrac47}

Therefore, the equation of the line is:

\mathsf{y=\dfrac47x-4}

For an inequality, the dashed line means < or >  (whereas a solid line means ≤ or ≥)

As the shading is below the line, we need to use <

Therefore, the final inequality is:

\mathsf{y < \dfrac47x-4}
