Hello
let : A(-2;1) B(1:10) and the equation is: y = ax+b
a = (yb -ya)/(xb -xa)
a = (10-1)/(1+2)
a = 3........ y = 3x+b
A passes by this line : 1 = 3(-2)+b
b = 7
the equation is : y= 3x+7
Answer:
<em>Question 3. Option B,</em>
<em>Question 4. Option D,</em>
<em>Question 5. Option B</em>
Step-by-step explanation:
Question 3.
If we have a table, we can note that each juice has a proportionality among one another - comparative to the number of servings. If we can figure out this proportionality, we can apply it to the servings of grapefruit juice;
As we can tell, this " proportion " is 1 to 2. Thus, the amount of grapefruit for 16 servings is 2 * 3 = 6c -<em> Option B</em>
Question 4.
The distance Carlos biked is 24 miles, the total distance he covered is 30 miles;
Question 5.
If 1 / 6 of the fruits are oranges, there must be 6 times of the other fruit. Thus, the solution is <em>Option B</em>
Volume (V) of a cylinder is the area of circular base (pi×r^2) times it's length/height (h):
h = 20.5 ft
diameter (d) = 1 1/5 × h, 1 1/5 = 6/5 = 1.20
d = 1.20 × 20.5 = 24.6 ft
radius (r) = 1/2 d = 24.6/2 = 12.3 ft
I’m pretty sure the answer is 12
Answer:
The system of equations 10d+25q=375 and q = 3d-2 can be used to find the numbers of dimes and quarters that Joann has.
Step-by-step explanation:
Given that:
Total value of dimes and quarters = $3.75 = 3.75*100 = 375 cents
One quarter = 25 cents
One dime = 10 cents
Let,
d be the number of dimes
q be the number of quarters
According to given statement,
10d+25q=375
q = 3d-2
Hence,
The system of equations 10d+25q=375 and q = 3d-2 can be used to find the numbers of dimes and quarters that Joann has.
