Answer:
No
Step-by-step explanation:
Based on the table, it would not have been from a linear function. To have a linear function, the x and y values would have to be increasing/decreasing at a constant rate.
This is the change from the first (x, y) pair to the second. Now, let's see if the next has the same change:
-7+4=-3
4-3=1
-3+4=1
3-2=1
Now, let's check the last one:
1+6=7
2-1=1
The y value is still changing by -1, but the x value has been increased by a different amount, therefore it is NOT a linear function.
Answer:
x = 48°
Step-by-step explanation:
42 + 90 + x = 180 (we can tell because it is a straight line and straight lines are supplementary, ie = 180)
Rearrange the equation so that x is on one side:
x = 180 - 90 - 42
Simplify
x = 48°
Answer:
The value of x is 
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the measure of arc DF
we know that
The inscribed angle measures half that of the arc comprising
so

we have

substitute

step 2
Find the measure of x
we know that
---> is a semi circle
we have

substitute

Answer:
QT = 45
Step-by-step explanation:
ST = 65
SP = 26
RQ = 30
QT = 4x - 3
Given that ∆STR is similar to ∆PTQ, therefore:

Plug in the values

Solve for x


Cross multiply


Collect like terms


Divide both sides by 8


✅QT = 4x - 3
Plug in the value of x
QT = 4(12) - 3 = 48 - 3
QT = 45
