3.)

∠1 = 60°

∠2 = 180° - 70° - 60°

= 50° (A)

4.)

∠3 = 180° - 40° - 60°

= 80°

∠4 = 180° - ∠3

= 180° - 80°

= 100° (H)

5.)

ΔABC = ΔCBD (B)

Reason :

ΔABC --> the angle is at B

ΔCBD ---> the angle is at B

Hope it helps and is useful :)

on a certain map 3/4 inch represents one mile .what distance in miles is represented by 1 3/4 inches

Studentka2010 [4]

Answer:

Step-by-step explanation:

3/4 inch to 1 mile = 1 3/4(or 7/4 in) to x miles

make a proportion

(3/4) (7/4)

-------- = ------- cross multiply

1 x

(3/4)(x) = (7/4)(1)

3/4x = 7/4

x = (7/4) / (3/4)

x = 7/4 * 4/3

x = 7/3 or 2 1/3 miles <===

Manuel and Sonja are shopping for school supplies. Manuel is buying 5 notebooks and 3 pens at a cost of $21. Sonja is buying 6 n

brilliants [131]

Answer: 6x+5y=28

Step-by-step explanation:

Looking at the first equation, we can tell that x stands for notebooks and y stand for pens. Since this talks about the total cost with the amount of products they bought, we can automatically eliminate the subtracting answer choices.

Now, we know that 6x+57=28 is the correct answer because Sonja bought 6 notebooks and 5 pens. This becomes 6x+5y.

Given that a function, g, has a domain of -1 ≤ x ≤ 4 and a range of 0 ≤ g(x) ≤ 18 and that g(-1) = 2 and g(2) = 8, select the st

Juli2301 [7.4K]

Answer:

Option 4 is correct.

Step-by-step explanation:

Consider a function g, it has a domain of -1 ≤ x ≤ 4 and a range of 0 ≤ g(x) ≤ 18. It is given that g(-1) = 2 and g(2) = 8.

The statement g(5) = 12 is not true because the value of x is 5 which is not in its domain.

The statement g(1) = -2 is not true because the value of function g(x) is -2 which is not in its range.

The statement g(2) = 4 is not true because g is a function and each function has unique output for each input value.

If g(2)=8 and g(2)=4, then the value of g(x) is 8 and 4 at x=2. It means g(x) is not a function, which is contradiction of given statement.

The statement g(3) = 18 is true because the value of x is 3 which is in the domain and the value of function g(x) is 18 which is in its range.

Therefore, the correct option is 4.
