Answer:

y=2.5

Step-by-step explanation:

first you add -3x to both sides so you get 5-3x and then divide that by 2 to get Y by itself so now you have 5/2 - 3/2x and when you put in the equation y=5/2 - 3/2x in DESMOS, the answer is 2.5

PLEASE HELP ASAP!!

Elza [17]

Answer:

The parabolic equation does not intersect the linear equation.

Explanation:

Given equation's:

y = x² − 5x + 9
y = -2x

To solve , use substitution method by inserting 2nd equation into 1st

$\sf y = x^2 - 5x + 9$

when substituted y = -2x

$\sf -2x = x^2 - 5x + 9$

collect terms

$\sf x^2 - 5x+ 2x + 9=0$

simplify

$\sf x^2 - 3x + 9=0$

Find discriminant:

$\sf b^2 - 4ac$

$\sf (-3)^2 - 4(1)(9)$

$\sf -27$

As the discriminant is negative, it tell us that they both does not intersect each other.

Change to a decimal: 14 1/2 %. 0.145 0.0145 14.5

bearhunter [10]

The answer is 0.145
14 1/2 can be expressed as:
 $14 \frac{1}{2} = 14+ \frac{1}{2} =14+ \frac{1*5}{2*5} = 14+ \frac{5}{10} = 14 + 0.5 = 14.5$

Since we know that x% is x/100, then 14 1/2 % can be expressed as:
14 1/2% = 14.5% = 14.5/100 = 0.145

AnnyKZ [126]

Answer:

More sod is needed

Step-by-step explanation:

Well we know that 3/4 of a bag of sod covers 55 ft^2 then if we divide 55 by 3 we get 18.3333 we take that and multiply by 4 to get 73.333 or the amount one bag of sod can cover

73.333*3 cuz 3 bags of sod is 220 ft^2

She needs more sod
