Answer:

Step-by-step explanation:

you subtract 7x from both sides and then divide both sides by 2 to get the value of y. This results in -7/2 x

PLEASE HELP, THIS MY LAST QUESTION. I WILL MARK BRAINLEST.

Answer:

Part 1: 30.35 runners

Part 2: 2024

Step-by-step explanation:

We will need to find an equation that best fits this data

The equation of best fit for this data is y = 2.16x - 4291.81

Now in order to figure our part 1, we will need to plug in 2001 for our x value to solve for y and we get:

y = 2.16(2001) - 4291.81 which then simplifies to y = 30.35

Then to figure out part 2, we need to plug in 80 (NOT 80,000 because the y-values are in thousands, meaning we only need to use the number 80) for our y-value and solve for x and we get:

80 = 2.16x - 4291.81
Adding 4291.81 to both sides we get: 4371.81 = 2.16x
Then dividing both side by 2.16 we get 2023.98 = x ≈2024

Evaluate of function h(3a)=x^4+2a^2+4

amid [387]

If you would like to evaluate function h(x) = x^4 + 2 * a^2 + 4 when x = 3a, you can do this using the following steps:

x = 3a
h(x) = x^4 + 2 * a^2 + 4
h(3a) = (3a)^4 + 2 * a^2 + 4 = 3^4 * a^4 + 2 * a^2 + 4 = 81 * a^4 + 2 * a^2 + 4

The correct result would be h(3a) = 81 * a^4 + 2 * a^2 + 4.

What is the value of the sum? - 3/8+ 5/10 -11/16 -1/16 1/16 1/4 -1/4

mafiozo [28]

First, you must convert the decimals to have the same denominator.

Find the least common multiple of both fractions' denominators:

Multiples of 8: {8,16,24,32,40}
Multiples of 10: {10,20,30,40}

The least common multiple of 8 and 10 is 40.

Multiply the fractions by a number that will make their denominator 40:

$- \frac{3}{8} \times \frac{5}{5} = - \frac{15}{40}$
$\frac{5}{10} \times \frac{4}{4} = \frac{20}{40}$

Now you can add these fractions together:

$-\frac{15}{40} + \frac{20}{40} = \frac{5}{40}$

Simplify this fraction:

$\frac{5}{40} \div \frac{5}{5} = \frac{1}{8}$

The answer should be 1/8.
