Answer:
at 7 months old, the cat weighs 4 kilograms
Step-by-step explanation:
all functions have an input and output. in this case, the question tells us that the information you put into the function is how many months old the kitten is, which is your input, 7. your output is the weight of the kitten in kilograms, so 4.
In one baseball season, Peter hit twice the difference of the
number of home runs Alice hit and 6. Altogether, they hit
18 home runs. How many home runs did each player hit
that season?
Answer:
Alice hit 10 home runs.
Peter hit 8 home runs.
Step-by-step explanation:
Let [tex]p[/tex] be the number of home runs Peter hit.
Let [tex]a[/tex] be the number of home runs Alice hit.
[tex]p=2(a-6)\\a+p=18\\\\a+2(a-6)=18\\a+2a-12=18\\a+2a=30\\3a=30\\a=10\\\\a+p=18\\10+p=18\\p=8\\\\p=2(a-6)\\8=2(10-6)\\8=2(4)\\8=8[/tex]
Find the x-intercept and y-intercept of the graph of of the equation: y=8-3x
Answer:
x-intercept: x = 8/3
y-intercept: y = 8
Step-by-step explanation:
x-intercept
[tex]y = 8 - 3x[/tex]
[tex]0 = 8 - 3x[/tex]
[tex]3x = 8[/tex]
[tex]x = \frac{8}{3} [/tex]
••••
y-intercept
[tex]y = 8 - 3x[/tex]
[tex]y = 8 - 3 \times 0[/tex]
[tex]y = 8[/tex]

Simplify: 4(5x-1)-8x+11=?
Slove: -5(x+1)+3x=6-(4x-3)=?
Answer:
1. 12x+7
2. x=7
Step-by-step explanation:
1. 4(5x-1)-8x+11=?
multiply 4(5x-1)
20x-4-8x+11
Subtract 8x from 20x which is 12x
then subtract 4 from 11 which is 7
12x+7
Answer:
4(5x - 1) - 8x + 11 = 12x + 7-5(x+1)+3x = 6-(4x-3) ↔ x = 7Step-by-step explanation:
4(5x - 1) - 8x + 11
= 20x - 4 - 8x +11
= 12x + 7
-5(x + 1) + 3x = 6 - (4x - 3)
↔ -5x - 5 + 3x = 6 - 4x + 3
↔ -2x - 5 = 9 - 4x
↔ 2x = 14
↔ x = 7
Determine if the lines are parallel, perpendicular, neither or the same line: y = -2x + 1 and 2x + y = 5.
Step-by-step explanation:
They are parallel.
Parallel lines have the same slope.
for the line y = -2x + 1 the slope is -2 and when we put the line 2x + y = 5 in general equation it will be y = -2x + 5, and it's slope is also -2.
Therefore, the lines are parallel

Answer:
C.
Step-by-step explanation:
The transformation ...
g(x) = f(ax)
represents a horizontal compression of the graph by a factor of 'a'. Here, the original function graph is compressed by a factor of 3 horizontally, so the curve will look a lot narrower.
The appropriate choice is C.

Find the smallest value of k such that 54k is a perfect square.
Answer: 6
Step-by-step explanation:
From the prime factorization of 54 you get:
54 = 2×3×3×3
So ,
You can write it as,
54 = 2×3^2×3,
Make sure all of the factors are in square form, so we add a another 2 and a three to the factors to make them all in square form
You get
=2×3^2×3×2×3 (the last 2×3 is added because one 2 and 3 were not having another pair so they were added to make them squares)
So k is basically 2×3 which is 6
And 54×6 gives us 324, which is a perfect square.
Part A Find the value of x
x=20
x=35
x=70
x=110
Part B Find the measure of the unlabeled angle in the previous question
40°
70°
110°
140°
Answer: x = 35
Step-by-step explanation: The sum of all the angles is equal to 360.
2*(x+y+5)+y+2x=360
Opposite angles are equal: y = 2x
Substitute y=2x into the first: 4x+6x+10 = 360: x=35 (y = 70)

Find the measure of JL.[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Given, K is the midpoint of JL. So, JK = KL.
KL = 14x - 1JK = 8x + 11JL = ?________
JL = JK + KL (given that K is the midpoint of JL)
JL = (8x + 11) + (14x - 1)
________
[tex] \large \boxed{\mathfrak{Steps} \downarrow}[/tex]
[tex] \sf( 8 x + 11 ) + ( 14 x - 1 )[/tex]
Combine 8x and 14x to get 22x.
[tex] \sf \: 22x+11-1 [/tex]
Subtract 1 from 11 to get 10.
[tex] \boxed{ \boxed{ \bf22x+10 }}[/tex]
________
Also given that, JK = KL.
So, (8x + 11) = (14x - 1)
⇨ (8x + 11) = (14x - 1)
⇨ 8x + 11 = 14x - 1
⇨ 11 + 1 = 14x - 8x
⇨ 12 = 6x
⇨ x = 12 / 6
⇨ [tex] \boxed{ \boxed{ \bf \: x= 2 }}[/tex]
________
Now, value of JL will be,
JL = 22x + 10
Substitute the value of x.
JL = 22(2) + 10
JL = 44 + 10
[tex] \boxed{ \boxed{ \bf\: JL = 50 }}[/tex]
⇨ So, the value of JL will be 50 units.

rectangle A has a side length of 12 cm and another side of 8cm. rectangle B has a side length of 15 cm and the other side is 8 cm. are they scale copies?
Answer:
No
Step-by-step explanation:
In order to find if they are scale copies we need to check if the ratio betwenn the two lengths and between the two widths are equal.
The ratio of the lengths is 12 : 15 = 4 : 5
The ratio of the widths is 8 : 8 = 1: 1
Since th ratio are different then the are not scale copies.

If a truck starts from rest and it has acceleration of 4m/s square for 5 second , calculate it's final velocity . What will be the distance travelled by the truck during the time interval
Answers:
Final Velocity = 20 m/s
Distance Traveled = 50 meters
======================================================
Explanation:
The truck starts from rest, so its initial starting velocity is 0 m/s. I'll denote this as Vi = 0.
The final velocity is what we want to find, so we want to solve for Vf.
The acceleration is a = 4 m/s^2.
The change in time is t = 5 seconds.
So,
a = (Vf - Vi)/(t)
4 = (Vf - 0)/5
4*5 = Vf
20 = Vf
Vf = 20
The final velocity is 20 m/s.
---------------------
Now let's calculate the distance traveled using the following kinematics equation:
d = 0.5*(Vi+Vf)*t
d = 0.5*(0+20)*5
d = 0.5*(20)*5
d = 10*5
d = 50
The truck travels a total distance of 50 meters.
---------------------
This is another way to calculate the distance traveled where we don't need to find Vf
d = Vi*t + 0.5*a*t^2
d = 0*5 + 0.5*4*5^2
d = 0 + 2*25
d = 50
However, since your teacher wanted you to compute Vf, I think you should stick to the previous set of steps.
A gardener plants 20 trees in a straight line. The trees are 5 m apart. What is the distance between the first tree and the last tree.
A Distance between 1st tree and 2nd tree is 5m
similarly it's 10m between 1st and 3rd trees and so on.
So, the total distance between the first and last tree will be :
[tex] \hookrightarrow \: (n -1) \times d[/tex]
where,
n = number of trees d = distance between each tree[tex] \hookrightarrow \: (20 - 1) \times 5[/tex]
[tex] \hookrightarrow \: 19 \times 5[/tex]
[tex] \hookrightarrow \: 95[/tex]
Therefore, the distance between first and last tree is 95 m.
