Answer:
D and E
Step-by-step explanation: Math
Answer:
Step-by-step explanation:
let the other angle be x
in complementary angle sum of two angle is 9 degree.so,
73.9+x=90 degree
x=90-73.9
x=16.1 degree
From the equation y = 4x, each strawberry contains 4 calories.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let y represent the number of calories in x strawberries. Hence:
y - 0 = [(27 - 0)/(6.8 - 0)](x - 0)
y = 4x
From the equation y = 4x, each strawberry contains 4 calories.

Answer:
There are no real factors for this.
Step-by-step explanation:
We could answer this either by checking each listed expression to see whether it is a factor of 9r^2-4r+1, or
We could take the coefficients of 9r^2-4r+1, determine the quantity b²-4ac (called the 'discriminant') and draw a conclusion based upon whether the discriminant is -, + or 0.
Let's use the 2nd approach.
Here, a = 9, b = -4 and c = 1.
Then the discriminant is b²2 - 4ac, or (-4)² - 4(9)(1), or 16 - 36.
Since 16 - 36 is negative, we conclude that this 9r^2 - 4r + 1 has NO REAL FACTORS.
Z=4t-5
z+t=180
z= 180-t
4t,-5=180-t
5t=185
t=37
180-37=z = 143
