Answer:
1. the vertex form of your function is f(x)= (x+-2)^2+-7
The vertex is at (2,-7)
2. So, the vertex form of your function is f(x)= (x+-7/2)^2 -41/4
The vertex is at (7/2, -41/4)

In a nursery, there are 5 adults and 14 children. Write the ratio of adults to
children in the form 1:n
*
can someone help me?
Answer:
5:14
Step-by-step explanation:
The ratio of adults to children using the form 1:n would look like this:
number of adults : number of children
So:
5 adults : 14 children = 5:14
Answer:
1 : 2.8
Step-by-step explanation:
in such a case what the question is asking you to is to compare the numbers and simplify them with the left hand number.
ratio of adult to children
write it as 5:14
put the 1 :n underneath
5 : 14 what we want to find is the n. among the 2 sides one is complete
1 : n only whole numbers. to get n look at the complete side . if
5:1 14=14 x 1 /5(cross multiplication). or you can
divide both sides by the left hand number(5)
5 and 14 = 1 : 2.8
5 5
the n is what we were trying to find and compare it to 1
this means for every 1 adult there are 2.8 children
Find the x-intercept of the line y=-4x +2. Write the point as a coordinate (x,
y).
Answer:
X intercept = 1/2
(x, y) = (1/2, 0)
Step-by-step explanation:
In order to find the x intercept, plug y = 0
y = - 4x + 2
Plug y = 0
0 = - 4x + 2
4x = 2
x = 2/4
x = 1/2
(x, y) = (1/2, 0)

The
of a nonvertical line passing through two points is the ratio of the rise to the run.
Answer: Slope
Step-by-step explanation:
Slope is rise over run. It can be calculated by dividing the change in y (rise) over the change in x (run).
The slope of a non vertical line passing through two points is the ratio of the rise to the run.
What is slope of a line?
The slope of a line is a measurement of its steepness and direction.The slope of a line formula computes the "vertical change" to "horizontal change" ratio between two distinct points along a line.
1. Slope of Parallel Lines :
A set of parallel lines always has the same inclination angle. Assume we possess two parallel lines l1 and l2 in the reference plane, inclined at angles θ1 and θ2 with the x-axis, respectively, such that the, θ2 = θ1.
m1 = m2
Therefore, the slopes of the two given parallel lines are equal.
2. Slope of Perpendicular Lines :
A pair of perpendicular lines always form a 90° angle. Imagine we have two perpendicular lines l2 and l1 in the coordinate plane, inclined at angles θ1 and θ2 with the x-axis, respectively, so that the provided angles follow the external angle theorem, θ2 = θ1 + 90°
m₁ = tan θ₁
m₂ = tan (θ₁ + 90º) = - cot θ₁
m₁ × m₂ = -1
Therefore, the product of slopes of two given perpendicular lines is equal to -1
Hence , The slope of a non vertical line passing through two points is the ratio of the rise to the run.

En un colegio hay 315 alumnos de los cuales 1/3 son mujeres y el resto hombres. 2/7 de los hombres juegan al fútbol y el resto al baloncesto. ¿Cuántos hombres juegan al baloncesto?
Answer:
150 hombres juegan baloncesto.
Step-by-step explanation:
En una escuela hay 315 alumnos de los cuales 1/3 son mujeres y el resto son hombres.
Paso 1
Encontramos el número de estudiantes que son mujeres
= 1/3 × 315
= 105 mujeres.
Se nos dice que el resto son hombres. Por lo tanto, el número de hombres que son estudiantes se da como:
= 315 - 105 mujeres
= 210 hombres
Paso 2
2/7 de los hombres juegan fútbol y el resto baloncesto.
Esto significa que 2/7 de 210 hombres juegan al fútbol
= 2/7 × 210 hombres
= 60 hombres
Por tanto, 60 hombres juegan al fútbol.
Paso 3
También se nos dice que el resto juega al baloncesto.
El número de hombres que juegan baloncesto se calcula como:
210 - 60
= 150 hombres.
Por tanto, 150 hombres juegan baloncesto.

Answer: D. SSS
Step-by-step explanation:
The solution would be SSS because the image shows that AB is congruent to DE, BC is congruent to EF, and AC is congruent to DF. Because the image shows that all three sides are congruent to their corresponding side on the other triangle, with no mention of angles, the triangles are congreunt through the SSS theorem.
A shop sells pairs of trainers for £52 each. They make a percentage profit of 30% on each pair. What was the cost of each pair of trainers to the shop?i will mark as brainliest if right answer.
Answer:
£15.6
Step-by-step explanation:
Method 1:
You are trying to find 30% of £52.
Therefore:
[tex]\frac{30}{100} * 52 = \frac{30 * 52}{100}[/tex]
If you solve this you will find that 30 × 52 = 1560, and 1560 ÷ 100 = £15.6.
So, the answer is £15.6.
Method 2:
You can solve 30% of £52 by using an algebra equation.
By using the rule that to convert a percentage to a decimal you divide by 100, you can change 30% to be 0.3.
Now, in order to write the equation, you will have to include 0.3 and 52.
The equation is:
0.3 * 52 = x
Once you multiply, you will find that the answer is £15.6.
I hope I helped!

Two teachers, Mr. Meehan and Mrs. Chipps, decide to buy compasses and rulers for their classrooms. Mrs. Chipps buys 30 compasses and 50 rulers for $95. Mr. Meehan buys 40 of each for $116. What are the individual costs of the compasses and rulers that were purchased? Explanation Please
Answer:
compass = $ 2.50 each ruler = $ 0.40 eachStep-by-step explanation:
Mrs. Chipps buys 30 c + 50 r = $95
Mr. Meehan buys 40 c + 40 r = $116 x (-1.25) to eliminate r
30 c + 50 r = $ 95
-50 c - 50 r = $-145
-20 c = -50
c = 50 / 20
c = $2.5
substitute c = 2.5 into eq. 1
30 c + 50 r = $95
30 (2.5) + 50 r = 95
75 + 50 r = 95
50 r = 95 - 75
r = 20 / 50
r = 0.40
therefore, the individual costs of the compasses and rulers are:
compass = $ 2.50 each
ruler = $ 0.40 each

Answer:X=3
y= -4
Step-by-step explanation:
If we're solving for x or y, then the intercept we're not solving for is equal to zero. Solving for y means x=0, solving for x means y=0.
so solving for x, 4x=12--> x=3, since y=0 in this scenario.
Solving for y, x=0, so -3y=12--> y=(-4)
9514 1404 393
Answer:
see below for a table
Step-by-step explanation:
You can easily identify intercept points by solving for one variable when the other is zero.
x-intercept (y=0)
4x = 12
x = 12/4 = 3
y-intercept (x=0)
-3y = 12
y = 12/-3 = -4
So, the coordinate pairs of these points are ...
(3, 0) and (0, -4)
__
If you solve for y, you get ...
-3y = 12 -4x
y = (4/3)x -4 . . . . . divide by -3
This suggests that x being a multiple of 3 will be useful for finding integer values of y.
We already have points for x=0 and x=3. We can add points for x=6 and x=-3.
y = 4/3(6) -4 = 4
y = 4/3(-3) -4 = -8
So, the additional points are ...
(6, 4) and (-3, -8)
What is the value of k in the function f(x)=112-kx if f(-3)=121?
Answer:
k = 3
Step-by-step explanation:
f(x) = 112 - kx ------------------(I)
f(-3) = 121
In equation (I) substitute x = -3
112 - k*(-3) = 121
112 + 3k = 121
3k = 121 - 112
3k = 9
k = 9/3
k = 3

He passes a sign which gives the speed limit as 60 mph.
By how much, in mph, did Alyn's average speed exceed the speed limit?

In a survey of 1046 adults conducted by Bradley Corporation, subjects were asked how often they wash their hands when using a public restroom, and 70% of the respondents said "always."
Identify the sample and the population.
Answer:
Sample = 1046
Population = All adults.
Step-by-step explanation:
In Statistics, a sample can be defined as a set of items, objects or individuals collected, selected or drawn from a population. Thus, a sample is a subset of a population. In this scenario, the sample is 1046.
On the other hand, population can be defined as the total number of individuals in a survey. Thus, all the adults are a population.

Answer:
x = 10
Step-by-step explanation:
Okay the two sides are going to equal the same measure soo...
4x + 9 = 11x - 61 (Subtract 4x on both sides)
9 = 7x - 61 ( add 61 on both sides)
70 = 7x (divide both sides by 7)
10 = x

The triangles ΔJMK and ΔLMK are congruent. Then the value of the variable 'x' will be 10.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
In triangles ΔJMK and ΔLMK, then we have
∠JMK = ∠LMK = 90° (Right angle)
∠JKM = ∠LKM (Given)
KM = KM (Common side)
The triangles ΔJMK and ΔLMK are congruent with each other. Then the sides JK and KL will be equal. Then the value of 'x' will be given as,
KL = JK
11x - 61 = 4x + 9
11x - 4x = 61 + 9
7x = 70
x = 70 / 7
x = 10
The triangles ΔJMK and ΔLMK are congruent. Then the value of the variable 'x' will be 10.
