Answer:
17.5
Step-by-step explanation:
Pythagorean Theorem is a^2 + b^2 =c^2
a= 9 , b= 15, c= x
9^2 + 15^2 = c^2
= c^2
c= 17.493 or 17.5 rounded to the nearest tenth
First, divide each side by 4 to get y alone on the left side.
y=-6/4x+2
The y intercept is 2
Answer:
We will take option B.
Step-by-step explanation:
Option A) |4 − 1| = 3 units
Option B) |4 − (−1)| = 5 units
Option C) |−4 + (−1)| = 5 units
Option D) |−4 − (−1)| = 3 units.
Now, from the number line and from the points given on the number line it is clear that the distance from one point to another is 5 units.
So. option B or Option C can be the right one.
Now, the right side point is on +4 point and the left side point is on -1 point.
So, the distance between those points will be calculated as 4 - (- 1) = 5.
Therefore, we will take option B. (Answer)
Answer:
Step-by-step explanation:
Use the point-slope formula.
y - y_1 = m(x - x_1) you have : x_1 =5 and y_1 =1
m the slope m= -1 (same slope for the line : x+y=9 because this lines are parallel and you can write y=-x+9
an equation for this line is : y-1 = -(x-5)
In 3 1/2 lb is the same as 7 of 1/2 lb so
2.80/7= $0.4 per 1/2 lb
One pound costs 0.4•2= $0.8
