Answer: 15 months

Step-by-step explanation:

Her balance after paying the registration fee is $300. Then we need to divide this remaining money into as many chunks (months )of $20. So we do 300/20 = 15 months

Y = 3.2 – 24<br> 5x - y = 8<br> The solution is
Yuki888 [10]
X= -8
Y= -48

Explanation:
Since we know that 3x-24 is equal to y, we can plug that in for y in the equation 5x-y=8. That would look like 5x-(3x-24)=8. Distribute the -1 and you will get 5x-3x+24=8. Subtract 24 from both sides and get 2x=-16. Divide both by 2 and get x=-8. Than plug in -8 for y in one of the equations to get the y. You will get -48.

9. Look at triangle RST below.<br><br> Which side of the triangle is the longest?
Lera25 [3.4K]

Answer:

ST is longest

Step-by-step explanation:

  • <em>Theorem: </em>
  • <em>If one side of a triangle is longer than another side, then the angle opposite the longer side will be larger than the angle opposite the shorter side</em>

The values of the angles are:

  • ∠S= 50°,
  • ∠T= 60°,
  • ∠R= 180°- (50°+60°)= 180° - 110° = 70°

Since ∠R is the largest angle, the side ST is longest

If f(x) = 3x^2-10x+2 find the vertex of y=f(x+4)-5
allochka39001 [22]

3 {(4 + x)}^{2}  - 10(x + 4) + 2 - 5
so
3( {x}^{2}  + 8x + 16) - 10x - 40 + 3
so
3 {x}^{2}  + 14x + 11
take differential calculus
6x + 14 = 0
you will find x then y
