Answer 1

Answer:

7)Bagel costs $3.5 and muffin cost $1.25

8) Ticket is $9 while snacks are $2

9) Correct because left hand side is zero

10) Correct because they both have same slope and same y-intercept

Step-by-step explanation:

7) Let bagel be x and muffin be y.

Thus;

For Aaron;

x + 3y = 7.25 - - - (1)

For bee;

x + 2y = 6 - - - (2)

Subtract eq 2 from eq 1 to get;

y = 1.25

Put 1.25 for y in eq 2;

x + 2(1.25) = 6

x + 2.5 = 6

x = 6 - 2.5

x = 3.5

Bagel costs $3.5 and muffin cost $1.25

8) Let movie ticket be x and snacks be y.

Thus;

2x + 3y = 24 - - - (1)

3x + 4y = 35 - - - (2)

Multiply eq(1) by 3 and eq(2) by 2 to get;

6x + 9y = 72 - - - (3)

6x + 8y = 70 - - - (4)

Subtract eq 4 from eq 3 to get;

y = 2

Put 2 for y in eq 3;

6x + 9(2) = 72

6x + 18 = 72

6x = 72 - 18

6x = 54

x = 54/6

x = 9

Ticket is $9 while snacks are $2

9) using elimination, subtract eq 1 from eq 2, we will see that the entire left hand side is equal to zero.

Thus, no solution exists because we can't isolate the variable to get an answer.

10) The answer is correct because for a system of 2 simultaneous equations to have infinite solutions, they both have to have the same y-intercept and also same slope.

In this case, their y-intercept which is when x is 0 is;

3(0) + y = 9

y = 9

Their slope is also the same equal to 3.

Consider the function f(x) = 2 + 2x - 15. What are the x-intercepts of the function?

Answers

Answer:

x=6.5

Step-by-step explanation:

I got the x- intercept as 6.5 because I found the x value when y equals 0.

0=2+2x-15

Next, I added 2+-15 and got -13.

0=2x-13

Then, I added 13 to both sides so that I could have x by itself.

13=2x

Next, I divided 2 on both sides so I could find the value of x.

6.5= x

In conclusion, the x- intercept of f(x)=2+2x-15 is 6.5.

84 is the answer I think

Answer:

a = 72 mm is the answer.

Step-by-step explanation:

a = ?

b = 21 mm

c = 75 mm

According to the Pythagoras theorem

a² + b² = c²

a² + 21² = 75²

a² + 441 = 5625

a² = 5625 - 441

a² = 5184

a = 72 mm

∴ a = 72 mm is the length of the missing leg.

Alicia, Jamar, and Tia collect dimes for charity. Alicia collects (3k+4) dimes. Jamar collects twice as many dimes as Alicia. Tia collects 4(5+6k) dimes. How many dimes do they collect altogether in terms of k?

Answers

Answer:

33k+32

Step-by-step explanation:

Assign Variables :

Alicia- A

Jamar- J

Tia- T

Write equations :

A = (3k+4)

J= 2(3k+4)

T=4(5+6k)

Simplify equations:

A= 3k+4

J= 6k+8

T= 20+24k

Add:

(3k+4)+(6k+8)+(20+24k)

3k+6k+24k+8+20+4

33k+32

45 x 45 - 36 x 36 = 729 the square root of 729 is 27

Answer:

a = 27 m is the answer.

Step-by-step explanation:

a = ?

b = 36 m

c = 45 m

According to the Pythagoras theorem,

a² + b² = c²

a² + 36² = 45²

a² + 1296 = 2025

a² = 2025 - 1296

a² = 729

a = 27 m

∴ a = 27 m is the length of the missing leg.
