Mathematics
1 answer:
Scorpion4ik [409]3 years ago
6 0

Answer:

10

Step-by-step explanation:

The answer is 10 because there are 20 days and no home work is due on 7 of those days so that’s 13 days with homework from math or writing. Then you take the three days where it was just math and subtract that to get 10 days of writing.

The diagonal AC is drawn in parallelogram ABCD Which method can NOT be used to prove that AABC is congruent to ACDA?
diamong [38]

Answer:

B SSA

Step-by-step explanation:

Geometric proofs can be used to show that the two triangles are congruent using ASA, SAS and SSS.

However, there is no such thing as SSA in geometry because an angle and two sides can not show congruence of triangles. This is so because the angle is not an included angle.

Is (-5,-5) a solution of y&gt; - 2x + 4?
valina [46]

Answer:

No

Step-by-step explanation:

Let's check by substituting -5 for y and -5 for x:

y > -2x + 4

-5 > -2 * (-5) + 4

-5 > 10 + 4

-5 > 14

However, we know that -5 is definitely not greater than 4, so we know that (-5, -5) is NOT a solution to the given inequality.

Hope this helps!
