How are maps of cities like dilations? GEOMETRY WILL GIVE BRANLIEST.

1 answer:

Dilations change the size of an object or image. In this case, a city map changes the city's size and makes it smaller so that it can be read.

1-A 2-A 3-B

$- 104 \geqslant - 8b - 8$

put -8 near -104

$- 104 + 8 \geqslant - 8b$

$- 96 \geqslant - 8b$

b will be alone.

$\frac{ - 96}{ - 8} \geqslant \frac{ - 8b}{ - 8}$

$b \geqslant 12$

Answer A

$3m - 7 > - 4$

$3m > - 4 + 7$

$3m > 3$

$\frac{3m}{3} > \frac{3}{3}$

$m > 1$

Answer A

İf

$m \geqslant 1$

The answer would be D

But answer A

$- 4x + 4 > - 16$

$16 + 4 > + 4x$

$20 > 4x$

$\frac{20}{4} > \frac{4x}{4}$

$x < 5$

Answer B

We learnt this way in Turkey.

Find f(x) and g(x) so that the function can be described as y = f(g(x)). y = 7/sqrt 8x +10

Blizzard [7]

Assuming you meant

$y = \frac{7}{ \sqrt{8x+10} }$

Then you can compose the function g(x)

$g(x)= \sqrt{8x+10}$

With the function

$f(x)= \frac{7}{x}$

Because f (g(x) ) means that you first find (calculte) $\sqrt{8x+10}$ and second you divide 7 by g(x) to obtain 7 / [√(8x+10) ].

(4x + 8x - 5) + (3x2 + 6x - 7)

ch4aika [34]

Answer:

7x^2 + 14x - 12

Step-by-step explanation:

Add like terms:

(4x + 8x - 5) + (3x2 + 6x - 7) becomes:

4x^2 + 8x - 5 or (grouping like terms in columns):

+ 3x^2 + 6x - 7

---------------------

7x^2 + 14x - 12

Two number cubes are rolled for two separate events:

andrew11 [14]

Answer: $\bold{P(B|A)=\dfrac{P(B\cap A)}{P(A)}=\dfrac{11}{30}}$

Step-by-step explanation:

The probability of Event B given Event A = the intersection of Event A and B divided by the probability of Event A. (see below for the symbols)

$P(B|A)=\dfrac{P(B\cap A)}{P(A)}$

P(A) = (1, 6), (1, 5), (1, 4), (1, 3), (1, 2), (1, 1)

(2, 6), (2, 5), (2, 4), (2, 3), (2, 2), (2, 1)

(3, 6), (3, 5), (3, 4), (3, 3), (3, 2), (3, 1)

(4, 5), (4, 4), (4, 3), (4, 2), (4, 1)

(5, 4), (5, 3), (5, 2), (5, 1)

(6, 3), (6, 2), (6, 1)

= 30

P(B) = (1, 2), (2, 1) sum = 3

(1, 5), (2, 4), (3, 3), (4, 2), (5, 1) sum = 6

(3, 6), (4, 5), (5, 4), (5, 4), (6, 3) sum = 9

(6, 6) sum = 12

= 12

P(A ∩ B) = (1, 2), (2, 1)

(1, 5), (2, 4), (3, 3), (4, 2), (5, 1)

(3, 6), (4, 5), (5, 4), (5, 4), (6, 3)

= 11

Question 15 of 43

Andrews [41]

Answer:

Option A

Step-by-step explanation:

$\frac{12}{25} \times \frac{11}{24} \times \frac{10}{23} \times \frac{9}{22}$

we start with 12 red marbles out of 25 marbles, that's the probability for the first.

in the second step we have one red marble less, wich also means one marble less overall

and so on

$\frac{12 \times 11 \times 10 \times 9}{25 \times 24 \times 23 \times 22}$

$= \frac{11880}{303600}$

can be reduced by 1320 (step by step) to

$\frac{9}{230}$
