Answer:
The answer is x = 5.
Step-by-step explanation:
Given:
Δ ABC is an Isosceles triangle with AB = CA
m∠ ABC = ( 6x + 4 )°
m∠ BAC = 73°
m∠ BCA = ( 8y - 7 )°
To Find:
x = ?
Solution:
Properties of an Isosceles Triangle.
- Base angles or two angles are equal.
- Any two sides are equal.
Here , Δ ABC is an Isosceles triangle with AB = CA
∴ m∠ BAC = m∠ BCA

∴ m∠ BCA = ( 8y - 7 )°
= 8 × 10 - 7
m∠ BCA = 73 Which is same as ∠ CAB
Property of a Triangle is Sum of the measures of the angle of a triangle is 180°.

Substituting the values we get,

The answer is x = 5.
64*3= 192 I multiplied that because the car traveled for 3 hours at the speed of 64 miles.
64-15= 49 I subtracted 15 out of 64 because the car only traveled 45 minutes after the three hours.

EG
Step-by-step explanation:
Hi there!
I like to think of input and output like coordinates on a graph. So, the input is also called domain, and is also the x coordinate on a graph. The output is also called the range, and is also the y coordinate. For example, in the coordinate (5,7), 5 would be the input, and 7 would be the output.
Now for relation and function. A function is where each x, or the input, can only be assigned to one y: but this is where it gets a little tricky. Although an x value can only be assigned to one y, and y value can be assigned to multiple x's. Let's say for the x values you have 3 and 8, and for your y values you have 7 and 4. 3 can't be assigned to both of these, however, both 3 and 8 could be assigned to the same y. (feel free to ask me for more clarification on this, I know it's a little hard to remember). For relation, it's the opposite of what I just explained. The x values can be assigned to as many of the y values they want. For example, with the last numbers, 3 could be assigned to both 7 and 4 at the same time.
Again, feel free to ask me for more clarification, I'm just trying to keep this from sounding really complicated.
I hope I helped! :)
