What are the solutions to x^2-13x+30

BlackZzzverrR [31]

$ax^2+bx+c=0 \\ \\
x^2-13x+30 = 0 \\ \\ D=b^2-4ac = 169-120=\sqrt{49} =7 \\ \\ x_{1/2} = \frac{-b^2+/-\sqrt{D}}{2a} = \frac{13+/-7}{2*1} \\ \\ x_1 = \frac{13+7}{2} = 10 \\ \\ x_2 = \frac{13-7}{2} = 3$

Tanner is ordering a pizza at a restaurant. The cost of a cheese pizza is $8.69, and then it costs $0.30 for each additional top

Grace [21]

Answer:

Option A. $c=8.69+0.30t$

Step-by-step explanation:

Let

t ------> the number of additional toppings

c ----> the cost of the pizza in dollars

we know that

The linear equation that represent this situation is

$c=0.30t+8.69$

This is the equation of the line in slope intercept form

where

the slope m is equal to

$m=0.30\frac{\$}{topping}$

the y-intercept b is equal to

$b=\$8.69$ -----> the cost of a pizza without topping

Ginger’s baby weighed only 3 3/8 pounds when it was born. The doctor said it could not leave the hospital until it weighed 5 1/5

Zigmanuir [339]

To subtract 3 3/8 from 5 1/2,by turning into fractions[(5x2)+1]/2 = 11/2[(3x8)+3]/8 = 27/8 11/2 - 27/8To subtract fractions, your denominator needs to have the same number. so multiply it by 4 44/8 - 27/8 = (44-27)/8 = 17/8.17 / 8 pounds or 2 and 1/8 because 17 / 8 = 2 remainder 1. In terms of weight that is 2.125 pounds.
