Answer:
y=3x+5
Step-by-step explanation:
Point slope equation:
y=mx+b
m-slope, b- is y-intercept
equation given 2 points
y-y1 = m(x-x1)
For point (1,8) and slope m=(y2-y1)/(x2-x1) = 20-8/5-1=12/4=3
y-8 =3(x-1)
arange it in point slope format
y-8=3x-3
y=3x-3+8
y=3x+5

Alyn drives 20.4 miles in 17 minutes.
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?
Answer:
12 mphStep-by-step explanation:
Speed = distance/time
Distance = 20.4 milesTime = 17 minutes = 17*1/60 hours = 17/60 hoursSpeed is:
20.4 : 17/60 =20.4*60/17 =72 mphAlyn exceeded the limit by:
72 - 60 = 12 mphFind 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)

What do you call the set of points after you apply the transformation?
Answer:
The "prime"
Edit: the "prime" is specifically the tic mark that you have to do after a transformation, so there are many names, but my teacher taught me that "prime" is a good way.
Step-by-step explanation:
Answer:
A transformation is a change in the position, size, or shape of a geometric figure. The given figure is called the preimage (original) and the resulting figure is called the new image.

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.

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

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.

I WILL MARK YOU BRAINLIEST IF YOU EXPLAIN TO ME HOW TO DO IT
Answer:
Step 1: Draw the points TUVW using the given coordinates (you already did T).
Step 2: For the reflection, in each coordinate replace the x coordinate with -x. E.g., T becomes T' (6,1). Reflection in y axis means the x coordinates swap their sign.
Step 3: Draw the reflected rectangle T'U'V'W'.
Step 4: Replace each coordinate of step 3 with x-5 and y+7, e.g., T' becomes T'' (1, 8)
Step 5: Draw T''U''V''W''
Answer:
see explanation
Step-by-step explanation:
(a)
Under a reflection in the y- axis
a point (x, y ) → (- x, y ) , thus
T(- 6, 1 ) → T'(6, 1 )
U(- 1, 0 ) → (1, 0 )
V(- 2, - 5 ) → V'(2, - 5 )
W(- 7, - 4 ) → W'(7, - 4 )
(b)
The translation rule (x, y ) → (x - 5, y + 7 ) means
Subtract 5 from the original x- coordinate and add 7 to the original y- coordinate, that is
T(- 6, 1 ) → T'(- 6 - 5, 1 + 7 ) → T'(- 11, 8 )
U(- 1, 0 ) → U'(- 1 - 5, 0 + 7 ) → U'(- 6, 7 )
V(- 2, - 5 ) → V'(- 2 - 5, - 5 + 7 ) → V'(- 7, 2 )
W(- 7, - 4 ) → W'(- 7 - 5, - 4 + 7 ) → W'(- 12, 3 )

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.

Slowhan decides to play a very fun game. He starts off with his favorite
odd integer. For every turn, Slowhan will either add 1 or subtract 1 to his current number.
What is the probability that after 11 turns, the resulting number will be odd?
Answer:
Answer is even on the 11th turn unless Slowhan is allowed to skip a turn.
Step-by-step explanation:
If you add or subtract every turn then every turn will always be the opposite of the last turn, so, it would be.
odd is 0
1 = even
2 = odd (You've seen here that every even numbers of turns how answer will be odd and when it is an odd number of turns it will be even)
3 = even
4 = odd
5 = even
6 = odd
7 = even
8 = odd
9 = even
10 = odd

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.

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.

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.
