Answer: ×=5
Step-by-step explanation: Add 3 to both sides. simplify. Subtract 2× from both sides of the equation and u will get ×≡5
for the area of the smaller semicircles
area = 1/2 x 3.142 x 5 x 5
area = 39.275cm²
for the larger circle
area = 1/2 x 3.142 x 10x 10
area= 157.1cm²
but since part of it is out and is replaced again
..total area of shaded part is 157.1cm² + 39.275cm² - 39.275cm²
area =157.1cm²
Answer:
(-3,-43) and (3,107)
Step-by-step explanation:
input 25x+32 for y
25x+32=5x²+25x-13
32=5x²-13
-5x²=-45
x²=9
x=+-3
which means you separate the solution
x= -3
x= 3
then input the answers you got for x, in both equations. Then you'll get your y.
y=25(-3)+32
-43
Then check your answer.
Then input the other answer you got for x.
I may be wrong, but I tried and checked my answers.
23.25 plus 10.5 is 33.75 so now its 33.75 ounces in 15 servings now you do a unit rate which is to find out how many ounces are in 1 serving so you do 33.75 divided by 15 which equals 2.25 check it in do 2.25 times 15 and get 33.75
Answer 2.25
Answer:
- x² + 11x - 28
Step-by-step explanation:
y = - (x - 4)(x - 7) ← expand factors using FOIL
= - (x² - 11x + 28) ← distribute parenthesis by - 1
y = - x² + 11x - 28 ← in standard form
