Answer:
Correct option: first one
Step-by-step explanation:
The graph has 3 different parts:
Cost = 15 when the Gigabytes used is lesser than or equal 2,
Cost from 20 to 40 when the Gigabytes used is greater than 2 and lesser than or equal 6.
An increase of 4 gigabytes caused an increase of 20 in the cost, so the slope is 20/4 = 5, and the y-intercept is:
20 = 5*2 + b -> b = 10
Cost = 50 when the Gigabytes used is greater than 6.
So the correct option is the first one
12 lbs
Since 3 lbs cost $6, and you want to find how many lbs can be bought with $24, 24/6 is 4, so you multiply 3 by 4 and get 12
The general equation of circles is (x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center. 1. 2x^2+2y^2=72 =x^2+y^2=36 c: (0,0); r = 62. (x-3)^2+(y-1)^2=4 : c: (3,1); r = 23. (x-5)^2+(y+2)^2=49; c: (5,-2); r = 74. (y-4)^2+(x-10)^2=64: c: (4,10); r = 85.(x^2-6x+9)+(y^2+8y+16)=1: c: (3,-4); r = 16. x^2+12x+y^2-8y=-27 =x^2+12x + 36+y^2-8y+16=-27+36+16=25: c( -6,4); r = 5
Answer:
<h2>w² - 2(w)(1) + 1² = w² - 2w + 1 = (w - 1)²</h2>
Step-by-step explanation:
(a - b)² = a² - 2ab + b²
We have
w² - 2w = w² - 2(w)(1)
We must add 1²
w² - 2(w)(1) + 1² = (w - 1)²
The two lines intersect at (-3,4)
-2/3X+2= -2X-2
Add 2X to both sides
Subtract 2 from both sides
Divide both sides by 4/3
You get X=-3
Plug in 3 to one of the equations and you’ll see that y= 4
