Si colocan en 16 pisos, 16 ladrillos. ¿Cuántos ladrillos pusieron en total?. (expresarlo en forma de potencia)
Answers
Answer:
Númer total de ladrillos= 256
Step-by-step explanation:
Dada la siguiente información:
Total de pisos= 16
Total de ladrillos por piso= 16
Para calcular cantidad de ladrillos en total, tenemos que usar la siguiente formula:
Número total de ladrillos= total de ladrillos^2
Número total de ladrillos= 16^2
Númer total de ladrillos= 256
En este caso lo hace al cuadrado por que la cantidad de pisos y ladrillos por piso es la misma. Sino, es mejor expresarlo como una multiplicación.

Answers
Answer:
y = -4/3 x + 2
Step-by-step explanation:
Let us assume the equation given is 3y + 4x = 6
The standard form in slope-intercept form is y = mx+c
m is the slope
c is the intercept
Make y the subject of the formula
3y + 4x = 6
3y = -4x + 6
Divide through by 3
3y/3 = -4/3 x + 6/3
y = -4/3 x + 2
Hence the equation of the line in slope-intercept form is y = -4/3 x + 2

Given the equation of line y = -2x : Does the point M( 1/2 , 1) belong to the graph?
PLEASE HELP ME! I promise to mark brainliest if you give me the correct answer. Thank you!!
Answers
Answer:
no it does not belong to the graph
Step-by-step explanation:
plug in the x-coordinate and see if it gives you the y-coordinate (1). if 1 is what comes out, then it is not a point on the graph.
y = -2(1/2)
y = -1
y = -1 when x = 1/2, which is not 1 so it does not belong to the graph

Step-by-step explanation:
I know this was posted a week ago, but, if you still need help:
You can set up a proportion, as follows.
50 / 2 = 40 / x => where x = frequency in Hz,

Answers
Answer:
B
Step-by-step explanation:
all you need to do is add 5 to the y for example ( -5, 5) add 5 to the (x,5) to make ( -5,10). As you can see only the y value is shifting, not the x value, that's why you need to add 5 to all the y values.
So the answer here is B.
Answer:
B
Step-by-step explanation:
The answer is B because 5 units up from 5 is 10. A and B both have a y coordinate of 5 and the answer letter B is the only one that mention 10 as a y coordinate twice

Answers
Answer:
4, 8 and 16
Step-by-step explanation:
a/r ×a×ar =512
a^3 =512
a = cube root of 512
a=8
8/r+8+8r=28
8r^2+8=20r
8r^2-20r+8=0
8r^2-16r-4r+8=0
8r(r-2)-4(r-2)=0
(8r-4)(r-2)=0
r=2
8r=4
so r=2 or r=1/2
so of r is 2
8/2=4
