Answer 1

Answer:

B is the answer.

x = 1

y = 2

Step-by-step explanation:

In B, Multiply the second equation by 2

8y - 2x = 14                

Now add the first and the equation above.

8y - 2x = 14

3y +2X = 8

11y = 22        

Divide by 11

11y/11 = 22/11

y = 2

Use the given equation #2

4y - x = 7

4*2 - x = 7

-x = 7 - 8

-x = - 1               Multiply by - 1

-1*x = -1*-1

x = 1

Step-by-step explanation:

The distance, d, that an object foto is directly proportional to the square of the time, t, it has been in free fall. An object that has been in free fall for 8 seconds has fallen 1024 feet. Determine the distance the object has fallen if it has been falling for 2 seconds

Answers

Answer:

d = 64 feet

Step-by-step explanation:

Given that d is directly proportional to t² then the equation relating them is

d = kt² ← k is the constant of proportion

To find k use the condition t = 8 , d = 1024 , then

1024 = k × 8² = 64k ( divide both sides by 64 )

16 = k

d = 16t² ← equation of proportion

When t = 2 , then

d = 16 × 2² = 16 × 4 = 64 feet

Jordan’s family exchanged 250 dollars for 5000 pesos.
Jordan bought a sweater for 550 pesos.
How much dollars is it for the cost of one peso

Answers

The number of dollars for one peso is 20 dollars.

Exchange rate is the rate at which one currency is exchanged for another currency.

In order to determine how many pesos can be exchanged for a dollar, the value of pesos would be divided by the amount of dollars exchanged.

Exchange rate = 5000 / 250 = 20 dollars

This means that 1 peso would be exchanged for 20 dollars.

find slope of line with the points (-5,-4) and has a slope of -3/5

Answers

Answer:

-3/5

Step-by-step explanation:

The answer is already in your question. You're asking for the slope of a line with an already stated slope

Answer:
(-7, 1)
Step-by-step explanation:

Okay, have you heard of the formula y = mx + b?
M = slope
B = y-intercept (what point the line is crossing on the y axis (0, _) )

So what to do with this information? Let’s start by plotting (-5, -4)

Since we know the slope is -3/5, we will go down 3 points from (-5, -4) and to the right 5 points. Our new points will be (-7, 1)

Given that (3^-2×4^-2)^-3 = 12^x

⇛ [(3×4)^-2]^-3 = 12^x

Since a^m × b^m = (ab)^m

⇛(12^-2)^-3 = 12^x

⇛ 12^(-2×-3) = 12^x

Since (a^m)^n = a^mn

⇛ 12^6= 12^x

⇛6 = x

Since the bases are equal then exponents must be equal

Therefore,x = 6

If the bases are equal then exponents must be equal.

From a box of 120 mangoes, Brent sold 60%. How many mangoes were left?

Answers

Given:-

From a box of 120 mangoes, Brent sold 60%.

To Find :-

How many mangoes are left .

Solution :-

According to the question, box has 120 mangoes . The number of mangoes he sold will be ,

[tex]\longrightarrow[/tex] n(sold) = 60% of 120

[tex]\longrightarrow[/tex] n(sold) = 60/100 × 120

[tex]\longrightarrow[/tex] n(sold) = 3/5 × 120

[tex]\longrightarrow[/tex] n(sold) = 72

Hence the number of mangoes left will be ,

[tex]\longrightarrow[/tex] n(left) = 120 - 72

[tex]\longrightarrow[/tex] n(left) = 48

Hence the number of mangoes left is 48.

Step-by-step explanation:

the quotient of a number and 12 - 3 is -4

Answers

Answer:

-36

Step-by-step explanation:

12 - 3 = 9, so if the quotient of a number (let's call it x) and 9 is -4, we can create the following equation:

x ÷ 9 = -4

So, if we multiply both sides by 9, we get:

x = 9 * -4 which is -36.
