Nilda has $250 in her savings account. She plans to save $15 per week from her salary. Iona has only $200 in her account but can save $20 a week from her paycheck. How many weeks will it take before the amount in each savings account is the same?

Answers

Answer: 10 weeks

Step-by-step explanation:

Nilda's money = 250 +15x being x the number of weeks that have passed    

Lona's money= 200+20x

If they have the same amount, then

250+15x=200+20x

250-200=(20-15)x

50=5x

50/5=x

10=x

Answer:

10 weeks

Step-by-step explanation:

Nilda's money = 250 + 15x

Lona's money = 200 + 20x

250 + 15x = 200 + 20x

250 - 200 = (20 - 15)x

50 = 5x

10 = x

Step-by-step explanation:

which equation is y=(x+3)^2+(x+4)^2 rewritten in vertex form?

Answers

Answer:

[tex]y-1/2=2(x+7/2)^2[/tex]

Step-by-step explanation:

Equation of the Quadratic Function

The vertex form of the quadratic function has the following equation:

[tex]y-k=a(x-h)^2[/tex]

Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.

The given function is:

[tex]y=(x+3)^2+(x+4)^2[/tex]

Expanding the squares:

[tex]y=x^2+6x+9+x^2+8x+16[/tex]

Simplifying:

[tex]y=2x^2+14x+25[/tex]

Factoring 2 from the first two terms:

[tex]y=2(x^2+7x)+25[/tex]

The expression in parentheses must be completed to form the square of a binomial:

[tex]y=2(x^2+7x+49/4-49/4)+25[/tex]

Isolating the square of the binomial:

[tex]y=2(x^2+7x+49/4)-49/2+25[/tex]

Operating and Factoring:

[tex]y=2(x+7/2)^2+1/2[/tex]

Rearranging:

[tex]\boxed{y-1/2=2(x+7/2)^2}[/tex]

Comparing with the vertex form:

a=2, h=-7/2, k=1/2

Sara is selling tickets to a high school festival. She sold 10 less senior tickets than junior tickets and she sold 3 times as many sophomore tickets as junior tickets (no freshman allowed). Senior tickets cost $3, junior tickets cost $5 and sophomore tickets cost $7. Sara raised $782. Write an equation to model the situation so that we can find the amount of tickets sold to seniors, juniors, and sophomores.

Answers

Answer:

[tex]29x-30=782[/tex] where x denotes number of junior tickets.

Step-by-step explanation:

Let x denotes number of junior tickets.

Sara sold 10 less senior tickets than junior tickets.

Number of senior tickets [tex]=x-10[/tex]

Sara sold 3 times as many sophomore tickets as junior tickets.

Number of sophomore tickets [tex]=3x[/tex]

Senior tickets cost $3, junior tickets cost $5 and sophomore tickets cost $7.

Total amount raised by Sara [tex]=5x+3(x-10)+7(3x)=5x+3x-30+21x=29x-30[/tex]

Sara raised $782.

So,

[tex]29x-30=782[/tex]
