When you say two angles are complementary, they add up to 90 degrees.
Since two angles are the ratio 2:7, you can represent the smaller angle as 2x and the larger as 7x.
add them up as 2x+7x=90
2x+7x=9x 90/9x=10x
the angles are 2x=20 degrees and 7x=70 degrees
so the smaller angle is 20 degrees
-4x+7=2y-3
Put this in y=mx+b
-4x+10=2y
Switch it around
2y=10-4x
Put it in y=mx+b
2y=-4x+10
Divide by 2
y=-2x+5

; where a = 1, b = -4 and c = 8
3x^2y^4z - 6xy - 3z(5x^2) has three terms.
Answer:
Option 3 - The value of c is 3.
Step-by-step explanation:
Given : If 32 Superscript 2 c Baseline = 8 Superscript c + 7.
To find : What is the value of c?
Solution :
Superscript denotes the power.
32 Superscript 2 c i.e. 
8 Superscript c + 7 i.e. 
The equation form is
.
Write the expression as,


Comparing the base,





Therefore, the value of c is 3.
So option 3 is correct.
