Answer:
Step-by-step explanation:
4.5b + 8.5c = 175
b + c = 22.......b = 22 - c
4.5(22 - c) + 8.5c = 175
99 - 4.5c + 8.5c = 175
-4.5c + 8.5c = 175 - 99
4c = 76
c = 76/4
c = 19......there are 19 cats
b + c = 22
b + 19 = 22
b = 22 - 19
b = 3 <==== there are 3 birds
Throwing a ball, shooting a cannon, diving from a platform and hitting a golf ball are all examples of situations that can be modeled by quadratic functions. ... In many of these situations you will want to know the highest or lowest point of the parabola, which is known as the vertex.
The y-intercept is the value of y when the graph intersects the y-axis. Graphs intersect the y-axis when x=0, so we just substitute in x=0 to get:
y=2(0+3)(0+4)
y=2(3)(4)
y=24
Therefore, 24 is our answer.

The expression that represents Lonnie's final number is 2(x + 3) - 6
<h3>Writing an expression</h3>
From the given information, we are to write the expression that represents Lonnie's final number
From the given information,
"<em>kristy asks lonnie to think of a number, add 3 to it</em>"
Let the number be x
Then,
The statement becomes
x + 3
<em>"multiply the sum by 2</em>" we get
2×(x +3)
= 2(x + 3)
"<em> subtract 6</em>",
The expression becomes
2(x + 3) - 6
This is the expression that represents Lonnie's final number
Hence, the expression that represents Lonnie's final number is 2(x + 3) - 6
