Answer: x= infinite solutions

there are infinite solutions and when graphing it shows you that they are together they are infinte solutions

Step-by-step explanation:

15(x-3)/5=3(2x-3)

15(x-3)/5=6x-9

*5 *5

15(x-3)=30x-45

15x-45=30x-45

-15x -15x

-45=15x-45+45

+45

0=15x

0/15=x

0=x

$5 PAYPAL + BRAINLIEST TO ANSWER THS

Answer:

Quadratic Equation:

$3x^2=2x +5$

$\text{Standard Form: } 3x^2-2x-5=0$

From the standard form of a Quadratic Function, we get:

$a=3,\:b=-2,\:c=-5$

Discriminant:

$\Delta=\left(-2\right)^2-4\cdot \:3\left(-5\right)$

$\Delta=\left(-2\right)^2+4\cdot \:3\cdot \:5$

$\Delta=64$

From the discriminant, we conclude that the equation will have two real solutions.

State that:

$b^2-4ac$

$b^2-4ac =0:\text{The equation has 1 real solution}$

$b^2-4ac >0:\text{The equation has 2 real solutions}$

By the way, solving the equation given:

$x=\frac{2\pm\sqrt{64}}{2\cdot \:3}$

$x=\frac{2\pm\sqrt{64}}{6}$

$x=\frac{2\pm8}{6}$

$x_{1} =\frac{10}{6}=\frac{5}{3}$

$x_{2}=\frac{-6}{6} =-1$

a baseball and a bat cost $1.10 and if this bat costs .10 cents more than the ball. how much did the ball cost?

kari74 [83]

Define x:
Let the cost of the ball be x.
Ball = x
Bat = x + 0.1

The total cost is $1.10:
x + x + 0.1 = 1.1
2x + 0.1 = 1.1
2x = 1
x = 0.5

Find the cost of the bat and the ball:
ball = x = $0.50
bat = x + 0.1 = 0.5 + 0.1 = $0.60

Answer: The ball cost $0.50

Please explain and/or show your work!! :)

$\left[ \begin{matrix} 2 & a \\ -1 & -2 \end{matrix} \right] + \left[ \begin{matrix} b & 4 \\ -2 & 1 \end{matrix} \right]$

This addition of matrices can be combined into one matrix.
To add matrices, add the corresponding components of each matrix.

After adding, we'll have the following

$\left[ \begin{matrix} 2+b & a+4 \\ -3 & -1 \end{matrix} \right]$

This matrix should be equal to the matrix on the right-hand side of the equation. This means that each corresponding component of this matrix and the other matrix should be equivalent.

This means that

$2+b=1$
AND
$a+4=0$

Solving these one-step equations will give the values of a = -4 and b = -1. That's answer choice D.
