someone help me please i don’t understand

Answer:

The answer is 5.34 times 5, which is $27.70

Explanation: I would substitute 2 into x which would be y = 2(2) + 3. I would then multiply 2 and 2 which would give me 4 and then add 3 which I get 7. This means that (2,5) is not a solution to the equation.

Answer:

0

Step-by-step explanation:

f(-4) means x = -4 so then plug -4 into the function.

y = -4²-16

y = 0

Answer:

f(-4) =0

Step-by-step explanation:

f(x)=x²-16

Let x = -4

f(-4) = (-4)^2 -16

       =  16-16

       = 0

Answer:

y =  0.7(x^2 - 64x - 576)

Average rate of change = -49.

Step-by-step explanation:

As the x intercepts are -8 and 72 we can write the equation

y = a(x + 8)(x - 72)     where a is some constant to be found.

As it passes through point  (62, -490) we have, substituting:

-490 = a(62+8)(62-72)

-490 =  - 700a

a = 0.7

So the equation of the parabola

y = 0.7(x + 8)(x - 72) or

y =  0.7(x^2 - 64x - 576).

Average rate of change between x = -8 and x = 2

=  [0.7(2+ 8)(2 - 72) -  0.7(-8+8)(-8-72)] / (2 - -8)

= -490 - 0 /10

= -49

Answer:

Y = 130

X = 20

Z = 110

Answer:

y= 130 degrees  x= 20 degrees  z= 110 degrees

Step-by-step explanation:

I solved top left triangle first. So, we know all triangles add up to 180 degrees and we have two on the angles so 85 + 45 = 130 then 180 - 130 = 50 so the missing angle near y is 50. Now to figure out Y then you just subract your answer (50)  from 180 which you get 130. So y is 130 degrees. Then to figure out X, you just do 180 - 130 = 50, 50 - 30 = 20, so x is equal to 20 degrees. Then lastly to figure out z we know that the missing angle is 50 because its vertical to the other 50 degree so now you do 180 - 20 = 160, 160 - 50 = 110 degrees.

Answer:

-$5.50>x>$20

Elena has more than -$5.50 but less than $20.

Step-by-step explanation:

Ok, so the question says that Elena has -$5.50 in her account. That means that she owes someone ( the bank) $5.50.

Elena then mows the lawn which may have paid off her debt. But we don't know that for sure.

All they give us is that Elena has less than $20 in her bank account.

So your answer may look like this:

-$5.50>x>$20

Elena has more than -$5.50 but less than $20.

Elena earned, amount more than -$5.50 and less than $20 by mowing the lawn.

If two real numbers or the algebraic expressions are related by the symbols “>”, “<”, “≥”, “≤”, then the relation is called an inequality.

For example, x>3 (x should be greater than 3)

Given,

Account balance of Elena with her parents = -$5.50.

Which means she is in debt of $5.50.

Elena then  adds a certain amount of money to her balance by mowing the lawn,

which may have paid off her debt, that is not sure.

But,

Account balance of Elena after mowing the lawn is more than - $5.50 less than $20.

Let the money Elena earned by Elena earned mowing the lawn  = x

Then,

Possible amount she earned mowing the lawn = -$5.50 < x <$20.

Hence, Possible amount Elena earned mowing the lawn is

between -$5.50 and $20 = -$5.50 < x < 20.

Answer:d

Step-by-step explanation:

The fraction that represents Sharta's batting average is 583/1000.

A fraction is a mathematical representation of a part or parts of a whole. It consists of two numbers separated by a horizontal line, with the number above the line called the numerator and the number below the line called the denominator.

To convert a decimal to a fraction, we can use the place value of the decimal. In this case, Sharta's batting average is 0.583.

The decimal 0.583 can be expressed as a fraction by considering the digits after the decimal point.

The number 583 has three decimal places, so we can write it as:

= 0.583

= 583/1000

Therefore, the fraction that represents Sharta's batting average is 583/1000.

Answer: 2.6 pounds of CO₂

Step-by-step explanation:

1 kilowatt per hour produces 0.99 pounds of C02.

The watts used was;

= (5,657 * 28/60 hours) / 1,000

= ‭2,639.93333333

In kilowatts;

= ‭2,639.93333333/1,000

= 2.6399333 kilowatts

CO2 produced;

= 2.6399333 * 0.99

= 2.613533967‬

= 2.6 pounds of CO2
