-__y^2-[-5y-y(-7y-9)]-[-y(15y+4)]=0 please help I don’t know how to find the missing coefficient in the blank

Rama09 [41]

Hello,

if y≠0 then

$ay^2-[-5y-y(-7y-9)]-[-y(15y+4)]=0\\\\ay^2-[-5y+7y^2+9y]-[-15y^2-4y]=0\\\\ay^2+5y-7y^2-9y+15y^2+4y=0\\\\ay^2+8y^2=0\\\\(a+8)y^2=0\\\\a=-8\\\\\\$

Determine two coterminal angles in degree measure (one positive and one negative) for each angle. (There are many correct answer

Nat2105 [25]

Answer:

(a) Coterminal =495, -225

(b) Coterminal = 135,-585

Step-by-step explanation:

The angles are:

(a) 135° (b) −225°

The coterminal angle of angle x is derived by:

$Coterminal = x \± 360$

Solving (a): 135°

Substitute 135 for x in $Coterminal = x \± 360$

$Coterminal =135 \± 360$

Split

$Coterminal =135 + 360, 135 - 360$

$Coterminal =495, -225$

Solving (b): -225°

Substitute -225 for x in $Coterminal = x \± 360$

$Coterminal =-225 \± 360$

Split

$Coterminal = -225 + 360,-225 - 360$

$Coterminal = 135,-585$

Christine's middle school has a total of 900 students and 45 teachers . The local high school has 110 teachers & a student-t

qaws [65]

Answer:

2,200 students

Step-by-step explanation:

To find the number of students, create a proportion which is two equal ratios. Since the middle school and the high school are proportional then they have equal ratios.

$\frac{students}{teachers}= \frac{900}{45}=\frac{x}{110}$

Solve for x by cross multiplying by multiplying the numerator and denominator of each fraction.

900(110) = 45(x)

99,000=45x

2,200 = x
