A(-1,-4)
B(-5,-8)
C(-5,-4)
D(-4,-2)
I'll do one, you can use it as a basis for your answer.
Subtract 6 from both sides to get X by itself.
Now we divide by 7 for both sides as well.
Now we find the square root of 1 to figure out X.
Therefore, X=1.
my first answer in about a month. hope this helped.
Answer:
<u>1.8 ounces</u>
Step-by-step explanation:
Let :
⇒ weight of a can of juice = x
⇒ weight of an energy bar = y
=============================================================
Equations formed :
- 3x + 2y = 33.6
- 4y + 2x = 27.2
============================================================
Multiply Equation 1 by 2 :
⇒ 2 × (3x + 2y) = 2 × 33.6
⇒ 6x + 4y = 67.2 [Equation 3]
===========================================================
Subtract : Equation 3 - Equation 2
⇒ 6x + 4y - 4y - 2x = 67.2 - 27.2
⇒ 4x = 40
⇒ <u>x = 10</u>
===========================================================
Finding the weight of an energy bar :
⇒ 3(10) + 2y = 33.6
⇒ 2y = 3.6
⇒ y = <u>1.8 ounces</u>
Answer:
p(z<0.42) = 0.6628
Step-by-step explanation:
A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. That is to say:
μ = 0
σ² = 1
Using a calculator, we find that:
p(z<0.42) = 0.6628 (See picture attached)
The answer would be b.) angle C is congruent to angle E.
