Answer: -13/3
Step-by-step explanation: -1 5/8 -> -13/8 2 2/3-> 8/3
-13/8 x 8/3 = -104/24
= -13/3 OR -4 1/3
Answer:
x = 78º
y = 35º
Step-by-step explanation:
These are isosceles triangles
two angles are congruent
-----------------------------
x + 51 + 51 = 180
x = 180 - 102
x = 78º
y + y + 110 = 180
2y = 70
y = 35º
Answer:
2 real roots
Step-by-step explanation:
If the discriminant is any positive number, that means the quadratic will have 2 real roots, or solutions.
Since the discriminant, 36, is a positive number, this will apply.
So, if the discriminant is 36, there will be 2 real roots.
A. y=5+1.5d
b. after 20 days it will be 5+ 1.5 × 20 = 5+ 30= 35 cm
Hello logan693616!

A positive plus a negative will (always, sometimes, never) be negative.
Give an example that proves your answer:

A positive plus a negative will <u>sometimes</u> be negative.
- Suppose, we take a positive number whose value is greater than that of the negative number. While adding them, we'll take the sign of the greater number, which in this case is positive, so our answer will be a positive number. For example, <em>+4 + (-3) = <u>+1</u><u>.</u></em>
- Now, if we take a negative number which is greater than the positive number, the sum of the two numbers will be negative. For example, (<em>-4) + 3 = <u>-</u><u>1</u><u>.</u></em>
- So, the answer can actually depend based on the value of the numbers used.
- Hence, our answer is ⇨ A positive plus a negative will <u>sometimes</u> be negative.
