Answer:
2 < h <= 3
Step-by-step explanation:
4 + h <= 7
h <= 3 (subtract 4 on both side)
h + 1 > 3
h > 2 (subtract 1 on both side)
So, 2 < h <= 3
Create an equation for the total costs of driving x miles: 3.50 + 2.50x
since Sasha has $37, the equation would become: 3.50 + 2.50x = $37
subtract 3.50 from both sides: 2.50x = 33.50
divide 2.50 on both sides: x = 13.4
since the problem is asking for the greatest whole number of miles, you have to round down and the answer would be: 13 miles.
Answer:
All the coordinates are changed to
(x, y) ⇒ (2x, 2y)
Step-by-step explanation:
Given - A triangle is to be dilated with the origin as the center of dilation and with a scale factor of 2.
To find - Which answer choice correctly maps this dilation algebraically?
Proof -
Let ABC is a triangle where A, B, C are the vertices of the triangle respectively.
Now,
Let the coordinates be (x, y)
If a triangle is to be dilated with the origin as the center of dilation and with a scale factor of a , then the coordinated be changes as
(x, y) ⇒ (ax, ay)
Here given , a = 2
So, all the coordinates are changed to
(x, y) ⇒ (2x, 2y)
Answer:
x=-1/4
Step-by-step explanation:
-4/16=16x/16
-1/4=x
1 1/2 is the correct answer
