Answer:
(9,12).
Step-by-step explanation:
If a figure dilated by a scale factor of k and origin is the center of dilation, then the relation between point and its image is defined as
[tex]P(x,y)=P'(kx,ky)[/tex]
It is given that a figure is dilated by a scale factor of 3 and origin is the center of dilation. So,
[tex]P(x,y)=P'(3x,3y)[/tex]
We need to find the image of a vertex located at (3, 4). So, substitute x=3 and y=4 in the above rule of dilation.
[tex]P(3,4)=P'(3(3),3(4))[/tex]
[tex]P(3,4)=P'(9,12)[/tex]
Therefore, the image of a vertex located at (3, 4) is (9,12).

Find AB
picture is attached
Answer: AB = 15 units long.
Step-by-step explanation:
The triangles are identical.
You can infer this from both triangles sharing the side of BD and AD and CD marked as equal in length.
When triangles are identical, all three sides and angles are identical in length and measure, respectively.
Knowing this, we can set the sides of "5x" and "4x + 3" equal to each other in an equation to solve for x:
5x = 4x + 3
x = 3
When x equals 3, multiply x by 5 to find the side length of AB.
AB = 15 units long.
Is 5.130 greater than 5.13
Answer:
They are equal
Step-by-step explanation:
5.130 is equal to 5.13 because you simply added a zero onto the end of 5.13.
Adding a zero after a decimal is like adding a zero in front of an integer.
1.5 = 1.50
5 = 05
Can anyone help me solve this question thanks?
Answer:
X^2 + 8x + 15
Step-by-step explanation:
The only like terms are 5x and 3x so you add those together and sinse no other terms are similar you leave the answer at x^2 + 8x +15.
What’s the slope of the equation y = x + 6
Answer:
m (slope)=1
Step-by-step explanation:
y=x+6(m is always found in front of X so m=1)
Answer: 1
Step-by-step explanation: This equation is written in y = mx + b form.
The slope of the line will be the coefficient of the x-term.
Remember, the coefficient is the number in front of the variable.
Notice that the x does not have a coefficient.
When that happens, when there is no number in front
of your variable, you can put a 1 there to fill that position.
So the slope of the line will is 1.

In a class of 40 students, 8 are in the drama club and 12 are in the art club. If a student is selected at random, what is the probability that the selected student is...
1
...in the drama club?
1
...in the art club?
Answer:
20 percent for drama club
30 percent for art club
Answer:
p(drama club) = 1/5
p(art club) = 3/10
Step-by-step explanation:
Total number of students = 40
Number of students in drama club = 8
p(drama club) = 8/40 = 1/5
Number of students in art club = 12
p(art club) = 12/40 = 3/10

Adrian and his children went into a bakery and where they sell donuts for $1.50 each and brownies for $2.50 each. Adrian has $40 to spend and must buy a minimum of 20 donuts and brownies altogether. If x represents the number of donuts purchased and y represents the number of brownies purchased, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
10 donuts and 10 brownies
Step-by-step explanation:
In this case we must solve the system of equations that do not say in the statement:
at least 20 must be, therefore:
x + y = 20 => x = 20 - y
1.5 * x + 2.5 * y = 40
replacing:
1.5 * (20 - y) + 2.5 * y = 40
30 - 1.5 * y + 2.5 * y = 40
y = 40 - 30
y = 10
now for x:
x = 20 - 10
x = 10
therefore, to be a minimum of 20, they must be 10 donuts and 10 brownies

Cameron is going to the market to buy some vegetables. He has $20 to spend. He plans on buying peppers and onions. If he spends more than $12 on the onions, which inequality
represents the amount of money Cameron can spend on peppers, p?
Answer:
x = amount of money he spends on peppers
0<x<8
if it's 12 or more dollars than 20-12=8 which can be your greatest number and 0 being the lowest range based on the actual amount spent on onions. make sure to put a line under the inequality signs to show that it can also be equal to the number.
Find the solution to the system of equations.
Answer:
3x - 2 = -5x + 6
8x = 8
x = 1
y = 3 (1) -2
y = 3 - 2
y = 1
Step-by-step explanation:
Answer:
x = 1 and y = 1
Step-by-step explanation:
We want to find the solution. Our equations are:
y = -5x + 6
y = 3x - 2
Let's set these two equations equal to each other:
-5x + 6 = 3x - 2
8x = 8
x = 1
Substitute this back into any of the two equations to solve for y:
y = 3x - 2
y = 3 * 1 - 2 = 3 - 2 = 1
Thus, the answer is (1, 1), or x = 1 and y = 1.

PLEASE....HELP !!! WRITE PROPERLY PLEASE... CORRECT ANSWER PLSS...
Answer:
see below
Step-by-step explanation:
V = l*w*h
1. V = l*w*h
96 = 6*3.2 h
96 = 19.2h
Divide each side by 19.2
96/19.2 =h
h = 5
2. V = l*w*h
22 = l*2 *1.1
22 = 2.2l
Divide each side by 2.2
22/2.2 =l
10 = l
3. V = l*w*h
120 = 12*w *4
120 = 48w
Divide each side by 48
120/48 = w
w =2.5

Answer:
h = 2.5 cm
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular end, h is the length of prism )
Here V = 35 and h = 7, thus
7A = 35 ( divide both sides by 7 )
A = 5 cm²
Thus
A = [tex]\frac{1}{2}[/tex] × 4 × h = 5
2h = 5 ( divide both sides by 2 )
h = 2.5 cm

Answer:
x = 52
Step-by-step explanation:
the right angle means 90 degrees so add 90 and 34 to get 124 then when u subtract from 180 degree (the degrees of a triangle) you get 54 degrees. that means that p has to be 124 degrees. 124 subtracted by 72 is 52. Therefore x is 52.

At a concession stand, a pickle and two bags of chips costs a total of $3.25. Three pickles and four bags of chips costs a total of $7.25. To determine the cost of one pickle, Kevin is writing a system of equations. His first equation is shown below. Which of the following could be the second equation in his system of equations?
Answer:
A bag of chips costs $1
A pickle costs $1.25
Step-by-step explanation:
P + 2c = 3.25 Start with these two equations
3p + 4c = 7.25
p = -2c + 3.25 Solve for one variable
3(-2c +3.25) + 4c = 7.25 Substitute
-6c + 9.75 + 4c = 7.25
-2c = -2
c = 1
p + 2(1) = 3.25 Substitute
p + 2 = 3.25
p = 1.25

8^3 8^-5 8^y= 8^-2=1/8^2
Answer:
y=0
Step-by-step explanation:

We know that a^b * a^c = a^(b+c)
8^(3-5+y) = 8^-2
The bases are the same so the exponents must be the same

Answer:
b = -2
Step-by-step explanation:
Hello!
Solve the equation:
2b + 3 = 2 - 3(b + 3)2b + 3 = 2 - 3b - 95b + 3 = -75b = -10b = -2We can plug it back in to the original equation to see if it works:
2(-2) + 3 = 2 - 3(-2 + 3)-4 + 3 = 2 + 6 - 9-1 = -1The solution works.

To the nearest cent, how much interest will she earn in 3 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer:
1180.12
Step-by-step explanation:
p= 4000
r = 9% =0.09
t =3
plug in into B = p(1 + r)^t
B = 4000(1 + 0.09)^3
B = 4000(1.09)^3
B =5180.116 round to the 2 decimals
B = 5180.12
make the difference between B, the balance (final amount) and p, the principal (starting amount) = 5180.12-4000 =1180.12
