Respond to the following question with either a TRUE or FALSE: "The following parabola opens down: f (x) = -x2 + 5"
O TRUE because the leading coefficient is negative.
O TRUE because the linear function is negative.
O FALSE because the 5 is.positive.
O FALSE because this function is actually linear and not a parabola.
O I'm not sure how to approach this problem...yet.

Answers

Answer 1

Answer: A) True because the leading coefficient is negative

Explanation:

The leading term is -x^2 since this term has the largest exponent.

The leading coefficient is -1 as it's the coefficient of the leading term.

It might help to write -x^2 as -1x^2

The negative leading coefficient makes the parabola open downward, so each endpoint goes off to negative infinity. The graph looks like a frowny face. You can think of a negative emotion going with a frowny face, so that negative emotion matches with the negative leading coefficient. There are probably other ways to remember but that's the trick I use.

A ticket to a baseball game costs $32. Each soda at the game costs $4. Shawn may spend no more than $50. He buys 1 ticket and x sodas. (ignore what I wrote already i think it’s wrong)

Answers

Answer:

32 + 4x ≤ 50

Step-by-step explanation:

Cost of tickets = $32

Cost of soda = $4

Total spent = $50

When we say "no more than", we mean less than or equal to (≤)

He buys 1 tickets and x sodas

32 + 4x ≤ 50

4x ≤ 50 - 32

4x ≤ 18

Divide both sides by 4

x ≤ 18 / 4

x ≤ 4.5

Shawn can buy more than 4 sodas

how do I find the value of x so f(x)=7​

Answers

Answer:

x=5

Step-by-step explanation:

Here we are given with a graph.

we have been asked to find the value of x for which

As we know that , to find the value of x for the given value of f(x), we need to look onto the vertical axis, and mark a dot on the given value now draw a line perpendicular to vertical axis so that it cut the given straight line, and where they intersect draw another line perpendicular to the horizontal axis and you will get the value where it crosses the horizontal axis.

Hence we get x=5, then f(x)=7.

Write the equation of the line that passes through the points (4,9) and (9,1). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.

Answers

Answer:

y=-8/5x+77/5

Step-by-step explanation:

The equation of line that passes through the points (4, 9) and (9, 1) is y=-8/5x+77/5. Hope it helps!

The equation of line passes through the points (4, 9) and (9, 1) will be;

⇒ y = - 8/5x + 77/5

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (4, 9) and (9, 1)

Now,

Since, The equation of line passes through the points (4, 9) and (9, 1)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - 9) / (9 - 4)

m = - 8 / 5

Thus, The equation of line with slope - 8/5 is,

⇒ y - 9 = - 8/5 (x - 4)

⇒ y - 9 = - 8/5x + 32/5

⇒ y = - 8/5x + 32/5 + 9

⇒ y = - 8/5x + 77/5

Therefore, The equation of line passes through the points (4, 9) and (9, 1) will be;

⇒ y = - 8/5x + 77/5

If n divided by m equals 7/8,
what does m divided by n equal?

Answers

Step-by-step explanation:

1,

It is found that m divided by n is equal  to 8/7.

How can we interpret the division?

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.

Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.

Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

Thus,  a/ b = a divided in b equal parts.

If n divided by m equals 7/8, then m divided by n equal.

n / m = 7/8

Then m/n = 8/7

Therefore,  m divided by n is equal  to 8/7.
