The answer is 1 7/8. I got this by first looking at the two negatives. Negative times a negative is always a positive.So if you would write this expression again it would look like: -3 1/4 + 5 1/8

Now you find the common denominator which is 8. Convert -3 1/4 to have a denominator of 8: -3 2/8

Now you can convert both of those fractions into improper fractions: -26/8+41/8

Compute: 15/8

You can either leave your answer like that or you can change it into a mixed fraction :

1 7/8

Standard Form

Step-by-step explanation:

we know that

A quadratic function written in standard form is

[tex]y=ax^{2} +bx+c[/tex]

in this problem we have

[tex]y=2x^{2} +5x-1[/tex]  

so

[tex]a=2\\b=5\\c=-1[/tex]

Final answer:

The function y = -2x² + 5x - 1 is written in standard form, which for a quadratic function is ax² + bx + c.

Explanation:

The function given is y = -2x² + 5x - 1. This function is written in standard form, which is characterized by the quadratic term, followed by the linear term, and then the constant term. The general form of a quadratic function is ax² + bx + c, where a, b, and c are constants, and in this case, a is -2, b is 5, and c is -1.

The integer n can take any value between -45 and 45, satisfying the given inequality |−n| < 46 and leaving a remainder of 4 when divided by 7.

An integer n leaves a remainder of 4 when divided by 7 if it satisfies the given inequality |−n| < 46.

To find the possible values of n, we can solve the inequality.

|-n| < 46 → -n < 46 and -n > -46 → 46 > n > -46.

Therefore, n can take any integer value between -45 and 45, with the condition that it leaves a remainder of 4 when divided by 7.

the slope is 1/4

and the y intercept is -4

Hope this helps

Answer:

y = -1/4x +4

Step-by-step explanation:

Slope intercept form of a line will have y on the left and mx+c on the right.

y = mx+c

Here m is the slope and c is the intercept

Any form of line can be brought to slope intercept form

Given that 2x+8y =32

We have to keep y along on left side

Hence subtract 2x first

8y =-2x+32

Now divide by 8

y = -1/4x +4 is the equation in slope intercept form

Answer-

The total number of the 80 students responded to the poll.

Solution-

The percentage of student who responded that football was their favorite sport = 27.5%

The percentage of student who responded that basketball was their favorite sport = 17.5%

As the remaining students opted for others, so the percentage of student who opted other sport = 100-(27.5+17.5) = 100-45 = 55%

The number of student who chose others, was found to be 44. If total number of student participated in the opinion poll was x, then

[tex]\Rightarrow x \times\frac{55}{100} =44[/tex]

[tex]\Rightarrow x=44 \times\frac{100}{55}=80[/tex]

∴ The total number of the people who responded to the poll was 80.

Remember that: "Platinum Gym charges a one-time registration fee of $60, and membership is $20 a month."

We are solving for a membership that will make Edward's statement untrue, that the gym membership fee will NOT have a month where the cost is the same.

For example, I can say that:

" Bob's Gym charges a one-time registration fee of $50, and membership is $10 a month ".

In this case, the pricing is much lower than Platinum Gym's and would not have a chance of getting the same cost in the same month.

Another example can be:

" SuperSneaker's charges a one-time registration fee of $100, and membership is $30. "

Again, the cost is much more higher than Platinum Gym's and would not have a chance of getting the same cost in the same month.

2 squared X= 550

x = 550 square root

x=23.45

The solution to the equation [tex]2^x[/tex] = 550 is x ≈ 9.0959.

To solve the equation [tex]2^x[/tex] = 550, we need to isolate the variable 'x'. Here's the step-by-step process:

1. Take the logarithm (base 2) of both sides of the equation:

log2([tex]2^x[/tex]) = log2(550)

Using the property of logarithms, logb([tex]b^x[/tex]) = x, we have:

x = log2(550)

2. In this case, since we want to find x, we can use the logarithm function with base 2:

x ≈ log2(550) ≈ 9.0959

Therefore, the solution to the equation [tex]2^x[/tex] = 550 is x ≈ 9.0959.

The two integers between which the cube root of 50 lies are 3 and 4.

To find the two integers between which the cube root of 50 lies, we can start by evaluating the cube roots of consecutive integers until we find the two integers that enclose the cube root of 50.

Let's calculate the cube roots of some consecutive integers:

Cube root of 1: 1

Cube root of 2: 1.25992

Cube root of 3: 1.44225

Cube root of 4: 1.58740

Cube root of 5: 1.70997

Cube root of 6: 1.81712

Cube root of 7: 1.91293

Cube root of 8: 2

Cube root of 9: 2.08008

Cube root of 10: 2.15443

We can observe that the cube root of 50 is greater than the cube root of 27 (which is approximately 3), and less than the cube root of 64 (which is 4). Therefore, the cube root of 50 lies between 3 and 4.

Hence, the two integers between which the cube root of 50 lies are 3 and 4.

Initial amount in Elaine's account = m dollars ---- (1)

On December 8, total money deposited by Elaine = 1200 + r + 568.9

= r + 1768.9 ----- (2)

Total money on her account now = m + r + 1768.9

Total money she cashed by cheques = t + 73.7.

Therefore, her current balance in her account = (m + r + 1768.9) - (t + 73.7)

= (m + r - t) + 1695.2.

Hence, the algebraic expression that represents the amount of money in her account after the transactions is (m + r - t) + 1695.2.

Final answer:

Elaine's checking account balance after her transactions is represented by the algebraic expression m + 1200 + r + 568.90 - t - 73.70, with m being her initial balance, r the amount deposited, and t the amount from the check that was cashed.

Explanation:

Elaine had m dollars in her checking account. After various transactions, we can represent the amount of money in her account with an algebraic expression. The transactions include deposits and cashed checks. The deposits add money to her account, while cashing checks subtract money from her account.

To calculate the new balance, the following expression can be used:

New Balance = original balance + sum of deposits - sum of cashed checks

In Elaine's case, her initial balance is m dollars. She deposited $1,200, r dollars, and $568.90, which are added to her account. She also cashed checks for t dollars and for $73.70, which are subtracted from her account. Therefore, the algebraic expression representing the new account balance after these transactions would be:

m + 1200 + r + 568.90 - t - 73.70

(more than 6, oops)

The answer is 216 because we will compute 6^3 = 6*6*6 = 36*6 = 216

If we had 2 dice rolled out, then it would be 6^2 = 6*6 = 36. For each die added, we multiply another 6 because the die has 6 sides.

Visually, 2 dice form a 2D table of 36 possible outcomes. Three dice form a 3D cube of possible outcomes (a 6 by 6 by 6 cube with volume 216). You can think of it like a rubix cube. Each sub-block would house a possible combo such as {2,1,7} meaning that you rolled a '2' on the first die, a '1' on the second die, and a '7' on the third die.

Note: rolling a single die 3 times will produce the same sample space as rolling three separate dice 1 time.

Final answer:

To find the possible coordinates of point A with a known x-coordinate of -7 and a distance of 13 units from point B (5, 2), we used the distance formula and found two possible y-coordinates for point A, which are -3 and 7. Hence, the possible coordinates for point A are (-7, -3) and (-7, 7).

Explanation:

The question asks for the possible coordinates of point A given that point B has coordinates (5, 2), the x-coordinate of point A is -7, and the distance between points A and B is 13 units. To find the y-coordinate of point A, we can use the distance formula d = √((x2 - x1)^2 + (y2 - y1)^2). Substituting the known values, we have:

13 = √((5 - (-7))^2 + (2 - y1)^2)

Squaring both sides of the equation, we get:

169 = (12)^2 + (2 - y1)^2

This simplifies to:

169 = 144 + (2 - y1)^2

Subtract 144 from both sides:

25 = (2 - y1)^2

Now, taking the square root of both sides, we get two possible solutions for the y-coordinate:

y1 = 2 ± 5

Thus, the possible y-coordinates of point A are -3 and 7. Therefore, the possible coordinates for point A are (-7, -3) and (-7, 7).
