Answer:

y = -2 and x = 5

Step-by-step explanation:

2x + 3y = 4

-2x - y = -8

Since this is a system of equations, we can either substitute or subtract. I will be subtracting.

2x + 3y - 2x - y = 4 - 8

2y = -4

y = -2

Now that we have y, we will plug it in for the first equation and solve.

2x + 3(-2) = 4

2x - 6 = 4

    + 6  + 6

2x = 10

x = 5

Answer:

-2

Step-by-step explanation:

0.9x+2.3x = -6.4

Add the two values of the left side of the equation together

3.2x = -6.4

Divide both sides of the equation by 3.2

x = -6.4 / 3.2

x = -2

Answer:

Total Accrued Amount = $3,277.45

Interest Amount = $327.45

Step-by-step explanation:

A = $3,277.45

I = A - P = $327.45

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 7.4%/100 = 0.074 per year.

Solving our equation:

A = 2950(1 + (0.074 × 1.5)) = 3277.45

A = $3,277.45

The total amount accrued, principal plus interest, from simple interest on a principal of $2,950.00 at a rate of 7.4% per year for 1.5 years is $3,277.45.

Answer:

Total amount: $3,277.45

Interest: $327.45

Total: 2,950(1 + (0.074 x 1.5)) = 3,277.45

Interest: 3,277.45 - 2,950 = 327.45

Answer: 60

Lets make the people into variables first

Ted = x

Rosie = y

The sum of their ages is 72 so

x + y = 72

Ted is 5 times as old as rosie was when ted was Rosie's age

x = 5y

Now lets put in 5y instead of x so we can solve for y

5y + y = 72

6y = 72

y = 12

If y = 12 then we can put that in to get ted's age

x = 5(12)

x = 60

Ted is 60!

Lets check our work,

since we know the sum is 72 we can add their ages to check,

60 + 12 = 72

Yep! This is right.

Hope this helped! If you could mark branliest i'd appreciate it a lot. Let me know if you need anything else!

Answer: 60 is probably the answee

Answer:

Yes (6,1) is a solution to the inequality

Step-by-step explanation:

Plug in the coordinate point and check:

11(6)+3(1)>4?

66+3>4?

69>4

Since 69 is indeed greater than 4, then (6,1) is a solution to the inequality.

Answer: solve for p or solve for the inequality of p??

314.16 cm3     or   100pi

Answer:

100π

Step-by-step explanation:

[tex]V=\frac{pi r^{2} h}{3} \\ =\frac{pi*5^{2}*12 }{3} \\ =pi*5^{2} *4\\ =pi*25*4\\ =pi*100[/tex]

Sorry I had to write pi instead of π in the equation

substitute the "n" attached to 7 with 5

so it would be 7 times 5 which equals 35

Answer:

A. 40 2/9

Step-by-step explanation:

If I first multiply the whole numbers, so 2 x 5 x 4 that would equal 40. Next you can multiply the fractions, so 2/3 x 1/3 that equals 2/9. So the answer is 40 2/9

Answer:

188

Step-by-step explanation:

f(x)=4x² - 10+2

f(-7) = 4x² - 10 + 2

= 4(-7)² - 10 + 2

= 4 (49) - 10 + 2

= 196 - 10 + 2

= 188

Answer:

y = 4/3x + 11/3

Step-by-step explanation:

y2 - y1 / x2 - x1

1 - (-3) / -2 - (-5)

4 / 3

y = 4/3x + b

1 = 4/3(-2) + b

1 = -8/3 + b

b = 11/3

y = 4/3x + 11/3
