Your class hopes to collect at least 325 cans of food for the annual food drive. there were 135 cans donated the first week and
vampirchik [111]

They have collected 135+89=224 cans until now. To equal 325, they need 325-224=101 cans more.

A.

Let C be the number needed to equate atleast 325.

135+89+C\geq 325


B.

If we solve the inequality in part A, we can find minimum number of C to meet the goal of 325 cans.

135+89+C\geq 325\\224+C\geq325\\C\geq325-224\\C\geq101

<em>So they need minimum 101 to complete the target and more than that to surpass.</em>

ANSWER: 101 cans are needed to meet the goal and more than that to surpass the goal.

Which choice is equivalent to the following equation?<br> x = (-4)^2 +27
aleksandr82 [10.1K]

Answer:

x = y^{2} + -8y + 43

Step-by-step explanation:

(y - 4)^{2} + 27 = (y - 4) x (y - 4) + 27

(y x y) + (y x -4) + (y x -4) + (-4 x -4) + 27

(y^{2}) + (-4y) + (-4y) + (16) + 27

y^{2} + -8y + 43

Solve the quadratic equation 3x^2 +x-5=0 give your answers to two decimal places
ddd [48]

Especially if we're to present the answers to 2 decimal places, we'd gues that the roots of this polynomial are not "nice."

My suggestion is that we use the quadratic formula to find the roots, and then write the associated factors.

In 3x^2 +x-5=0, a=3, b=1 and c= -5. Thus, the roots are

-1 plus or minus √(1^2 - 4(3)(-5) )

x = --------------------------------------------------

2(3)

or:

-1 plus or minus √61 -1 plus or minus 7.81

x = ----------------------------------- = ---------------------------------

6 6

Then one root is 6.81/6, or approx. 1.14, and the other is

-8.81/6, or approx. -1.47.

The solution set is then {-1.47, 1.14}.
