Answer:
x/2 + 7 = -4
Step-by-step explanation:
7 more just means plus 7
a quotient of a number and blank basically is 'a number' (usually x) over a the number given if that makes sense. so in our scenario its x/2
'is' basically means is equal to
put it all together and you get x/2 + 7 = -4
hope this helps <3
Answer:
30°,40°
Step-by-step explanation:
let the other angles be 3x and 4x
3x+4x+110=180
7x=180-110=70
x=70/7=10
3x=3×10=30
4x=4×10=40
Step-by-step explanation:
DE = 5x-2
DF = 3(x+3)
3(x+3) = 3 + 5x-2
3x+9= 5x+1
2x=8
x=4
DE=5×4-2=18
DE=18
Answer:20π
Step-by-step explanation:
equation of the circle
(x+3)² + (y-5)² = r²
now, (-9, -3) lies on it
So, (-9+3)² + (-3-5)² =r²
36+ 64 = r² =100
hence, r =10
So, circumference = 2πr = 20π
Answer:
R: {-7,-2,3,8}
Step-by-step explanation:
The range is the output values of the function
The values or 8,3,-2,-7
We put them in order from smallest to largest
R: {-7,-2,3,8}
