2x + 5 > 7
2x > 7 - 5
2x > 2
x > 2/2
x > 1
Answer:
x-intercept(s): (
0
,
0
)
y-intercept(s): (
0
,
0
)
Explanation:
To find the x-intercept, substitute in 0 for y and solve for x
.
To find the y-intercept, substitute in 0 for x and solve for y
.
Well, since we know $3.65 is how much ONE PACK of pencil costs, and k represents the packs of pencils PURCHASED, and x represents the COST per pack, your answer would be A. x = 3.65k. This is because to find out the total cost (x) of k amount of packs, you would multiply the cost (3.65) times k, (known as 3.65k), which would be expressed as x = 3.65k. =)
Hope I helped! ^-^
Answer:
3 packages
Step-by-step explanation:
There are 1000 m in 1 km, so 2500 m is the same as 2.5 km.
1 package = 2.5 km
2 packages = 5.0 km . . . . still too little
3 packages = 7.5 km . . . . more than sufficient
Annabelle needs 3 packages of yarn to satisfy her requirement for 7 km.
Answer:
Step-by-step explanation:
Well, the center origin of the circle is given (h,k) = (-3,5).
Point on the circle is (x,y) = (1,8)
We have to find our radius as they gave us a point. from origin to the edge of the circle.
Using the formula: (x - h)^2 + (y - k)^2 = r^2
Plug in our (h,k) = (-3,5) and (x,y) = (1,8) to solve for radius.
(x - h)^2 + (y - k)^2 = r^2
(1 - (-3))^2 + (8 - (5))^2 = r^2
(4)^2 + (3)^2 = r^2
16 + 9 = r^2
r^2 = 25
r = 5
