Step-by-step explanation:
$1.80 per pound
The amount she's supposed to buy it is
1.80 × 12.5 = $22.5
She paid $21.25 for the 12.5 pounds, that means she saved
$22.5 - $21.25 = $1.25
the amount she saved per pound is
1.25/12.5 = $0.1 per pound
Answer:
![n * \frac{1}{2} = 95](https://tex.z-dn.net/?f=%20n%20%2A%20%5Cfrac%7B1%7D%7B2%7D%20%3D%2095%20)
Step-by-step explanation:
Required:
Select the equation that most accurately depicts the word problem
One-half of a certain number is 95.
Take the certain number to be n.
This statement in equation form will be:![n * \frac{1}{2} = 95](https://tex.z-dn.net/?f=%20n%20%2A%20%5Cfrac%7B1%7D%7B2%7D%20%3D%2095%20)
Therefore, the equation that most accurately depicts the word problem is ![n * \frac{1}{2} = 95](https://tex.z-dn.net/?f=%20n%20%2A%20%5Cfrac%7B1%7D%7B2%7D%20%3D%2095%20)
Although your options are incomplete, but this answer is correct.
The * symbol can be replaced with a dot sign
When you want to find the coordinates of vertices on coordinate plane, first :
1- look for the movement of the vertice parallel to x-axis (how many square houses did the vertice move to left or right?)if it moved right, the number is positive. if it moved left, then it's negative.
2- find out the movement of the vertice parallel to y-axis (how many square houses did the vertice move up or down?) if it moved up, the number is positive. if it moved down, it's negative
3- write the numbers as coordinates (x,y)
for example: the coordinates of this vertice is:
![\binom{4}{ - 6}](https://tex.z-dn.net/?f=%20%5Cbinom%7B4%7D%7B%20-%206%7D%20)
it moves 4 to right(positive) and 6 to down(negative)
good luck

Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 4x - 1 ← is in slope- intercept form
with slope m = - 4
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
, thus
y =
x + c ← is the partial equation of the line
To find c substitute (- 2, 2) into the partial equation
2 = -
+ c ⇒ c = ![\frac{5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2%7D)
y =
x +
← in slope- intercept form
