What is the equation of the line that passes through the point(1,7) and has a slope of -1

zhuklara [117]

Answer:

y = -1x + 8

Step-by-step explanation:

(1,7)

y = mx + b

7 = -1 × 1 + b

solving for b:

b = 7 - (-1)(1)

b = 8

Therefore,

y = -1x + 8

For what values of m does the graph of y = 3x2 + 7x + m have two x-intercepts

Irina18 [472]

we are given

$y=3x^2+7x+m$

To find x-intercept means we have to find zeros

and for finding zeros , we will use quadratic formula

and we have it has two x-intercepts

so, it's discriminant must be greater than 0

so, we will find discriminant

$D=\sqrt{b^2-4ac}$

now, we can compare with

$y=ax^2+bx+c$

$y=3x^2+7x+m$

and then we can find a , b and c

$a=3,b=7,c=m$

now, we can find D

$D=\sqrt{7^2-4*3*m}$

$D=\sqrt{49-12m}$

It has two x-intercepts

so,

$D=\sqrt{49-12m}>0$

now, we can solve for m

$49-12m>0$

$12m$

$m$ ............Answer

A school uses the function p(t)=t2−20t+175 to model the profit (in dollars) expected in a weekend when the tickets are sold at a

Arte-miy333 [17]

Answer:

$(a)\ t^2 - 20t + 75= 0$

$(b)$ $t = 5; t -=15$

Step-by-step explanation:

Given

$p(t) = t^2 - 20t + 175$

Solving (a): Equation when profit = 100.

This implies that:

$p(t) =100$

So, we have:

$100 = t^2 - 20t + 175$

Rewrite as:

$t^2 - 20t + 175 - 100 = 0$

$t^2 - 20t + 75= 0$

Solving (b): Calculate t, in (a)

In a, we have:

$t^2 - 20t + 75= 0$

Expand

$t^2 - 15t -5t + 75= 0$

Factorize

$t(t - 15) -5(t - 15)= 0$

Factor out t - 15

$(t - 5)(t - 15)= 0$

Split

$t - 5 = 0; t - 15 =0$

Solve

$t = 5; t -=15$

<em>The prices are $5 and $15, respectively</em>
