write the equation of a line that is perpendicular to the given line and passes through the given point
y-2=-1/4(x+3);(-3,5)
The point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
m - slope
We have the line
[tex]y-2=-\dfrac{1}{4}(x+3)\to m=-\dfrac{1}{4}[/tex]
If m₁ and m₂ are the slopes of the perpendicular lines, then
[tex]m_1m_2=-1\to m_2=-\dfrac{1}{m_1}[/tex]
Therefore the slope of ouer line is
[tex]m=-\dfrac{1}{-\frac{1}{4}}=4[/tex]
We have the point (-3, 5). Put the coordinates to the equation of a line in the point-slope form:
[tex]y-5=4(x-(-3))\\\\\boxed{y-5=4(x+3)}[/tex]
Julia is allowed to watch no more than 5 hours of telivison a week. So far this week, she has watched 1.5 hours. write and solve an inequality to show how many hours of teli she can watch this week. ( can u show your work along with it? )
Answer:
she can watch 3.5 hours this week.
Step-by-step explanation:
Julia is allowed to watch no more than 5 hours of television a week.
Let x be the number of hours she can watch per week
number of hours not more than 5 hours
so x<=5
She already watched 1.5 hours. so inequality becomes
x+ 1.5 <= 5
Now we solve for x
subtract 1.5 on both sides
x + 1.5 < = 5 - 1.5
x < = 3.5
So, she can watch 3.5 hours this week.
there are 11 regular players and 5 substitute players on a soccer team how many players are on 15 soccer teams ??
Answer:
225 players (including the substitutes)
Step-by-step explanation:
11 regular player and 4 substitutes makes 15 team members per team.
15 players on each team times 15 teams gives you 225 players in total.
The total number of players on 15 soccer teams can be calculated by multiplying the total number of players (including regular and substitute) on one team (16 players) by the number of teams (15), which equals 240 players.
Explanation:The subject of this question is Mathematics, and it's referencing a concept of multiplication in a real-world context. To determine the total number of players on 15 soccer teams, you consider that each team is composed of 11 regular players and 5 substitutes. So, the total number of players on one team is 16 (11 regular players + 5 substitutes).
To find out the number of players on 15 teams, you multiply the number of players on one team by 15. That is, 16 players * 15 teams = 240 players. So, there are 240 players on 15 soccer teams.

Dan wants to make 12 pancakes but what quantity of each ingredient should he use for 240g plain flour,2 eggs and 600ml milk?
To make 12 pancakes, Dan should use 20g of plain flour, 2 eggs, and 50ml of milk.
Explanation:To determine the quantity of each ingredient needed to make 12 pancakes, we can use the ratio of ingredients given in the recipe:
240g plain flour : 2 eggs : 600ml milk
To find the quantity of plain flour needed for 12 pancakes, we can set up a proportion:
240g / x = 12 / 1
Cross multiplying, we get:
x = (240g * 1) / 12
x = 20g
Therefore, Dan should use 20g of plain flour for 12 pancakes. Similarly, he should use 2 eggs and 50ml of milk for 12 pancakes.
Solve h + p = 4(k − 8) for k.
Answer:

h + p + 32 = 4k ( divide both sides by 4 )
k = [tex]\frac{h+p+32}{4}[/tex]
expand the brackets, to get 4k-32
sp you have; h + p = 4k - 32
add 32 to both sides== h + p + 32 = 4k
/4
k= (h + p+ 32)/4

A recursive rule for an arithmetic sequence is a1=-2; an=an-1 -9
What is an explicit rule for this sequence?
The explicit rule for the given arithmetic sequence is an = -2 + (n - 1) * (-9)
Explanation:An arithmetic sequence is a sequence of numbers in which each term is found by adding a common difference to the previous term. In this case, the recursive rule for the arithmetic sequence is given as a1 = -2 and an = an-1 - 9.
To find the explicit rule for this sequence, we need to find a formula that directly calculates the nth term of the sequence. We can do this by examining the pattern in the sequence:
First term: a1 = -2Second term: a2 = a1 - 9 = -2 - 9 = -11Third term: a3 = a2 - 9 = -11 - 9 = -20Fourth term: a4 = a3 - 9 = -20 - 9 = -29...From the pattern, we can see that each term is obtained by subtracting 9 from the previous term. So, the explicit rule for this arithmetic sequence is given by:
an = a1 + (n - 1) * d
where a1 is the first term, n is the term number, and d is the common difference. Plugging in the values, we have:
an = -2 + (n - 1) * (-9)
Simplifying this equation gives the explicit rule for the sequence.
Final answer:
The explicit rule for the arithmetic sequence is an = -2 + (n-1)(-9).
Explanation:
An explicit rule for an arithmetic sequence is given by the formula:
an = a1 + (n-1)d
Where:
an is the nth term of the sequence
a1 is the first term of the sequence
n is the position of the term in the sequence
d is the common difference between consecutive terms
In this case, the first term (a1) is -2 and the common difference (d) is -9. Therefore, the explicit rule for this sequence is:
an = -2 + (n-1)(-9)

Anyone know? Will mark brainliest if correct!
The answer is A. g(x).
Here's why:
f(x) = -x^4 - 2: This function is a downward-facing parabola (due to the negative coefficient of x^4) with a maximum y-value at its vertex. The vertex occurs at x = 0, and the maximum y-value is f(0) = -2.
g(x) = -3x^3 + 2: This function is a cubic function with a local maximum, but it does not have a global maximum. However, its maximum value is still greater than the maximum value of f(x).
Key points:
The maximum y-value of f(x) is limited to -2 because of the negative leading coefficient and the constant term of -2.
g(x) doesn't have a defined maximum y-value, but it can reach values greater than -2, making its maximum value larger than that of f(x).
Therefore, g(x) has the largest maximum y-value among the two functions.

Which value is the same as 2 tenths?
2 tenths is equal to 0.2 in decimal format. This is derived from its fraction format, 2/10, and its place value in the base-ten number system, which is a 'tenths' place.
Explanation:In mathematics, the value that is equivalent to 2 tenths is 0.2. This is because when we say 'tenths', we are referring to a fractional or decimal value that has a denominator of ten in the context of fractions or one place after the decimal point.
Therefore, 2 tenths is essentially 2 divided by 10 which equals 0.2 in decimal format. We can further illustrate this using a base-ten number system. In this system, each place to the right of the decimal point represents a 'tenths' place value. Therefore, in the number 0.2, the digit '2' is in the 'tenths' place.

Which of the following would earn the same amount of interest as a $600 principal with 2.5% interest for 6 years?
To earn the same amount of simple interest as $600 with 2.5% interest over six years ($90), another investment combination that would yield the same interest amount is $1,000 at 3% interest for 3 years.
Explanation:The student is asking which investment would earn the same amount of simple interest as a principal of $600 with 2.5% interest over 6 years. The formula for calculating simple interest is Interest = Principal imes Rate imes Time. For the given principal of $600 with 2.5% interest over 6 years, the interest earned would be:
Interest = $600 imes 0.025 imes 6
Interest = $90
To find another investment with the same interest earned, one must find a principal, rate, and time that satisfy the equation:
Interest Earned = New Principal imes New Rate imes New Time = $90
An example would be a principal of $1,000 with 3% interest for 3 years:
Interest Earned = $1,000 imes 0.03 imes 3
Interest Earned = $90
This indicates that both investments would earn the same amount of interest over their respective periods.
