Kevin has 17 trading cards Billy has t more trading cards then Kevin chose the expression that shows how many trading ingredient

sp2606 [1]

So we know that Kevin has 17 cards. The total number of cards that Billy has is 17 plus an unespecified number t. THis means that we have an addition of cards then the total number of cards that Billy has is given by:

$t+17$

And the correct option is A.

Breanna has $150 and she needs to save at least $560 for spring break trip if she can save $45 per week how long will it take he

melamori03 [73]

Answer: It will take her more than 9 weeks.

Step-by-step explanation:

If she already has $150 that will be constant and if she can save $45 per week the we will have the expression 45w where w is the number of weeks.

Together it will be 150 + 45w

Now the money has to be at least $560 so it will be

150 + 45w ≥ 560 Now solve for w

-150 -150

45w ≥ 410

w ≥ 9.1

Which means it will take 10 or more weeks t

Answer:

<h2>Function 1 has the least minimum value and its coordinates are (2. - 7).</h2>

Step-by-step explanation:

The first function is

$f(x)=2x^{2} -8x+1$

The second function is

x g(x)

-2 2

-1 -3

0 2

1 17

The vertex has coordinates of $V(h,k)$ , where $h=-\frac{b}{2a}$ and $k=f(h)$ .

Let's find the vertex for the first function where $a=2$ and $b=-8$ .

$h=-\frac{-8}{2(2)}=2$

$k=f(2)=2(2)^{2} -8(2)+1=8-16+1=-8+1=-7$

Therefore, the vertex of the first function is at $(2,-7)$ .

Now, the minimum value of the second function can be deducted from its table, which is $(-1,-3)$ .

Therefore, $f(x)$ has -7 as minimum value and $g(x)$ has -3 as minimum vale.

So, the right answer is B, because -7 is less than -3.
