Y=3x-8
y=5x-8
y=2x-8
y=1/3x-8
the y intercept is the b in y=mx+b and all of these have -8 as the y int

What is the cost of 1 shirt if I have 3 shirts and 2 scarves totaling $94?

Pepsi [2]

Let x be the cost of 1 shirt and y be the cost of 1 scarf.

Since, 3 shirts and 2 scarves cost $94, we have,

3x + 2y = 94

Since the number of unknowns is greater than the number of equations (2 > 1), the above system has infinitely many solutions.

If t is the cost of 1 scarf, then

3x + 2t = 94

3x = 94 - 2t

x = $\frac{94-2t}{3}$

For different values for t, we will get different values for x.

Set t = 2.

Then, x = $\frac{94-2(2)}{3}$

= $\frac{94-4}{3}$

= $\frac{90}{3}$

= 30

So, if the cost of 1 scarf is $2, then the cost of 1 shirt is $30.

X² + 3x + k = 0<br>pls help

denis-greek [22]

Answer:

$\left(h,\:k\right)=\left(-\frac{3}{2},\:\frac{9}{4}\right),\:p=-\frac{1}{4}$

Step-by-step explanation:

$x^2+3x+y=0$

$4\left\bigg(-\frac{1}{4}\right)\left\bigg(y-\frac{9}{4}\right)=\left\bigg(x-\left\bigg(-\frac{3}{2}\right)\right)^2$

$\bold{\mathrm{Therefore\:parabola\:properties\:are:}}$

$\left(h,\:k\right)=\left(-\frac{3}{2},\:\frac{9}{4}\right),\:p=-\frac{1}{4}$

Answer:

5. ○ $\displaystyle \frac{25}{48}$

4. ○ $\displaystyle \frac{25}{46}$

3. ○ $\displaystyle \frac{31}{100}$

2. ○ $\displaystyle \frac{3}{4}$

1. ○ $\displaystyle \frac{27}{50}$

Step-by-step explanation:

5. $\displaystyle \frac{25}{23 + 25} = \frac{25}{48}$

4. $\displaystyle \frac{25}{46} = \frac{25}{21 + 25}$

3. $\displaystyle Flat-out\:given\:to\:you$

2. $\displaystyle \frac{21 + 23 + 31}{100} = \frac{75}{100} = \frac{3}{4}$

1. $\displaystyle \frac{31 + 23}{100} = \frac{54}{100} = \frac{27}{50}$
