write the equation of the line passing through point 2, 5 and parallel to y=-1/2x-2
Answers
Answer:
option b
Step-by-step explanation:
explaination is in picture
Answer:
2nd option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - [tex]\frac{1}{2}[/tex] x - 2 ← is in slope- intercept form
with slope m = - [tex]\frac{1}{2}[/tex]
Parallel lines have equal slopes , then
y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (2, 5) into the partial equation
5 = - 1 + c ⇒ c = 5 + 1 = 6
y = - [tex]\frac{1}{2}[/tex] x + 6 ← equation of line

Kim is making cookies. She is using a recipe that calls for 1/4 cup of lemon juice. She has a 6 fl oz. bottle of lemon juice. There are 8 fl oz. of lemon juice in 1 cup. How many batches of cookies can she make?
Answers
Answer:
3
Step-by-step explanation:
Answer:
Step-by-step explanation:
1 cup = 8 fl oz
x cup = 6 fl oz Cross multiply
6 oz * 1 cup = 8 oz x divide by 8
x = 6 oz /8 oz = 3/4 cup
If kim needs 1/4 cup per batch then she will have enough for 3 batches of 1/4 cup each.
At a competition with 7 runners, medals are awarded for first, second, and
third places. Each of the 3 medals is different. How many ways are there to
award the medals?
Decide if this is a permutation or a combination, and find the number of ways
to award the medals.
Answers
Answer:
35 different combinations
Step-by-step explanation:
This would be a combination because the same person cannot get all three medals so permutation is not the correct way to calculate this. We use the formula C(n,r)=(nr)=n!(r!(n−r)!)=? where n is the number of total objects and r is the number of objects taken from the total.

−5x+4y=3
x=2y−15
what would be the values of x and y
Answers
Answer:
x=9 y=12
Step-by-step explanation:
eqn 1 - x=2y-15
eqn 2- -5x+4y=3
-5(2y-15)+4y=3
-10y+75+4y-3=0
-6y+72=0
y= 12
x=2y-15
x=2(12)-15
x= 9
Substitution,
-5(2y-15) + 4y=3
-10y + 75+ 4y=3
75-3 = 10y - 4y
6y = 72
y. = 72/6
Y= 12
Now find x
X= 2(12) - 15
X= 24 - 15
X= 9

Answers
Answer:
Step-by-step explanation:
(21 + 3y) + y = 90
21 + 4y = 90
4y = 69
y = 17.25
x = 21 + 3(17.25)
x = 21 + 51.75
x = 72.75
Answer check:
72.75 + 17.25 = 90
90 = 90 Corrrrrrect !
Explanation:
x = 3y + 21
And x + y = 90° (complementary angle)
Substitute x value in the equation:
3y + 21 + y = 90
4y + 21 = 90
4y = 69
y = 69/4
y = 17.25
x = 3(17.25) + 21
x = 51.75 + 21
x = 72.75
