since the scatterplot is up and down until day 5 and then it increases on day 6 and again on day 7

the average temperature increased from day 5 to day 7

Find the solution(s) to 22 +57-3 = 0. Check all that apply.

irakobra [83]

Answer:

x = -3 and x = 1/2

Step-by-step explanation:

To find the solutions to

2x² + 5x - 3 = 0

we can use the quadratic formula, as follows:

$x = \frac{-b \pm \sqrt{b^2- 4(a)(c)}}{2(a)}$

$x = \frac{-5 \pm \sqrt{5^2- 4(2)(-3)}}{2(2)}$

$x = \frac{-5 \pm 7}{4}$

$x_1 = \frac{-5 + 7}{4}$

$x_1 = 0.5$

$x_2 = \frac{-5 - 7}{4}$

$x_2 = -3$

Which expression is a difference of squares with a factor of 5x − 8?

Olegator [25]

Answer:

$25x^2-64$

Step-by-step explanation:

Remember that the formula for the difference of squares is $a^2-b^2=(a+b)(a-b)$ . The formula implies that if (5x - 8) is a factor, then (5x + 8) is the other factor. We can use our formula to find which one is our difference of squares:

$(5x-8)(5x+8)=(5x)^2-8^2$

$(5x-8)(5x+8)=5^2x^2-64$

$(5x-8)(5x+8)=25x^2-64$

We can conclude that the correct answer is $25x^2-64$ .
