Mathematics
1 answer:
jenyasd209 [6]3 years ago
5 0

Answer:

1. Y = 2, 1, 4, 7, 10

2. Y = -12, -8, -4, 0, 4

3. Y = -7, -5, -3, -1, 1

Step-by-step explanation:

all of the numbers in the x value you just substitute in the x place in problem

1. Y = 3x + 4

x: -2, -1, 0, 1, 2

Y = 3(-2) + 4

Y = -6 + 4

Y = -2

You then have:

x: -2, -1, 0, 1, 2

y: -2,

Y = 3(-1) + 4

Y = -3 + 4

Y = 1

You then have:

x: -2, -1, 0, 1, 2

y: -2, 1

just continue substituting each x variable into the x place to get your y variable.

I know you asked for the first 6 but I feel like if I just give you the answers to all of them you will not learn it, so I only gave the first 3, and I recommend trying to do the last 3 yourself. I'm sure you'll do well. <3

Find all points on the x-axis that are 14 units from the point (6,-7) All points on the x-axis that are 14 units from the point
Maksim231197 [3]

Answer: (6+7\sqrt{3},0)\text{ and }(6-7\sqrt{3},0) are the required points.

or  (18.124,0) and ( -6.124,0) are the required points.

Step-by-step explanation:

Let (x,0) be the point on x -axis that are 14 units from the point (6,-7) .

Then by distance formula , we have

\sqrt{(x-6)^2+(0-(-7))^2}=14\ \ \ [\ \because distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}]

Taking square on both the sides , we get

(x-6)^2+7^2=14^2\\\\\Rightarrow\ x^2+6^2-2(6)x+49=196\\\\\Rightarrow\ x^2+36-12x=147\\\\\Rightarrow\ x^2-12x=111\\\\\Rightarrow\ x^2-12x-111=0

Using quadratic formula : x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

x=\dfrac{12\pm\sqrt{(-12)^2-4(1)(-111)}}{2}\\\\\Rightarrow\ x=\dfrac{12\pm\sqrt{144+444}}{2}\\\\\Rightarrow\ x=\dfrac{12\pm\sqrt{588}}{2}\\\\\Rightarrow\ x=\dfrac{12\pm\sqrt{2^2\times7^2\times3}}{2}\\\\\Rightarrow\ x=\dfrac{12\pm14\sqrt{3}}{2}\\\\\Rightarrow\ x=6\pm7\sqrt{3}

so, (6+7\sqrt{3},0)\text{ and }(6-7\sqrt{3},0) are the required points.

since \sqrt{3}=1.732

so, (6+7(1.732),0)\text{ and }(6-7(1.732),0) are the required points.

i.e. (18.124,0) and ( -6.124,0) are the required points.

I need a specific explanation of how to answer this
zimovet [89]
A rectangle has two dimensions, width and length, and the area of it is their product.

since we know its area is 3x²-11x-4, then the two factors from that trinomial are the likely width and length, namely (3x + 1) (x - 4).

you can check them with FOIL.
