Step-by-step explanation:

We would do multiplication first, because of order of operations.

2x3=6

Now we add.

6+4=10

hope it helps! :3

What’s the answer to 14

mars1129 [50]

Step-by-step explanation:

EF = 6x - 4

and it is also the combination of EG and GF.

so,

6x - 4 = EG + GF = EG + 13

6x = EG + 17

now, we have additional information. EF bisects CD. that means it cuts CD in half.

and that means both banks must be off equal size.

5x - 1 = 7x -13

12 = 2x

x = 6

so, back to the first problem

6×6 = EG + 17

36 = EG + 17

19 = EG

The value 5 is an upper bound for the zeros of the function shown below.

Mice21 [21]

Answer:

The given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18 will be true.

Step-by-step explanation:

Given

$f\left(x\right)\:=\:x^2\:+\:x^3\:-\:11x^2\:-\:9x\:+\:18$

We know the rational zeros theorem such as:

if $x=c$ is a zero of the function $f(x)$ ,

then $f(c) = 0$ .

As the $f\left(x\right)\:=\:x^2\:+\:x^3\:-\:11x^2\:-\:9x\:+\:18$ is a polynomial of degree $4$ , hence it can not have more than $4$ real zeros.

Let us put certain values in the function,

$f(5) = 448$ , $f(4) = 126$ , $f(3) = 0$ , $f(2) = -20$ ,

$f(1) = 0$ , $f(0) = 18$ , $f(-1) = 16$ , $f(-2) = 0$ , $f(-3) = 0$

From the above calculation results, we determined that $4$ zeros as

$x = -3, -2, 1,$ and $3$ .

Hence, we can check that

$f(x) = (x+3)(x+2)(x-1)(x-3)$

Observe that,

$for x > 3$ , $f(x)$ increases rapidly, so there will be no zeros for $x>3$ .

Therefore, the given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18 will be true.

GalinKa [24]

Answer:

he should buy 128 oz of milk for 6.49

Step-by-step explanation:

2.49 divided by 32 equals 7 cents unless your rounding which would be 8 cents

4.99 divided by 64 is 7 cents too 8 if rounding

6.49 divided buy 128 oz would equal 5 cents so it is the cheapest.
