Answer:
There were 61 bagels and 23 coffee sold
Step-by-step explanation:
Let us solve the question
∵ The number of bagels and coffee sold by a bagel shop yesterday
can be modeled using the equation b + c = 84
∴ b + c = 84 ⇒ (1)
∵ Their sales for the same day can be modeled using the equation
2b + c = 145
∴ 2b + c = 145 ⇒ (2)
Let us solve the system of equations using substitution
→ Subtract the two sides of equation (1) by b to find c in terms of b
∵ b - b + c = 84 - b
∴ c = 84 - b ⇒ (3)
→ Substitute c in equation (2) by equation (3)
∵ 2b + 84 - b = 145
→ Add the like terms on the left side
∴ (2b - b) + 84 = 145
∴ b + 84 = 145
→ Subtract 84 from both sides
∵ b + 84 - 84 = 145 - 84
∴ b = 61
→ Substitute the value of b in equation (3) to find c
∵ c = 84 - 61
∴ c = 23
∴ There were 61 bagels and 23 coffee sold.
The answer i got is in the image below
The answer you get will pretty much already have a zero in it ...so thats why
If we see the protractor, we ill see that there is a horizontal line and a slant line. We have to see where the slant line touches the protractor. And as we see that the slant line touches the protractor at two angles which are 150 degree and 30 degree. But since the angle is acute , so 150 degree is not possible . So the correct option is 30 degree.
Answer:
D. (0, 0), (0,3), (-3, 3), (-3, 0).
Step-by-step explanation:
From the statement we know that the vertices of the triangle are:
(0,0) , (0, 3) , (3, 3) , (3, 0).
By multiplying the vertex matrix with the reflection matrix ![\left[\begin{array}{ccc}-1&0\\0&1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-1%260%5C%5C0%261%5Cend%7Barray%7D%5Cright%5D)
we create a reflection image in the y-axis.
So the result is letter D. (0, 0), (0,3), (-3, 3), (-3, 0).
