Answer:
7)
8)
Step-by-step explanation:
7) The equation of the straight line passing through the ordered pair (-3,5) and (3,-5) is given by
⇒ -3(y - 5) = 5(x + 3)
⇒ -3y + 15 = 5x + 15
⇒ 5x + 3y = 0
⇒ (Answer)
8) The equation of the straight line passing through the ordered pair (5,7) and (11,16) is given by
⇒ 2(y - 7) = 3(x - 5)
⇒ 2y - 14 = 3x - 15
⇒ 3x - 2y - 1 = 0
⇒ (Answer)
can u maybe write the full question?
Answer:
The number is 529 because is you square 23 it will become 529 which will then become 23 is you square root 529. (Hope this makes sense)
Step-by-step explanation:
Answer:
Y=60
Step-by-step explanation:
S+Y=90
S=(2*Y)-90
Y+2Y-90=90
3Y=180
Y=60
Plug back into S+Y=90
S+60=90
S=30
Answer:
The solution is (-17,80.5) and (1,8.5)
Step-by-step explanation:
Equation 1 :
Equation 2:
Substitute the value of y from equation 2 in equation 1
Equation 1 :
After substitution :
Substitute the value of x = -17
y = -4x+12.5
y = -4(-17)+12.5
y=80.5
Substitute the value of x = 1
y = -4(1)+12.5
y=8.5
Hence the solution is (-17,80.5) and (1,8.5)
