Brock is six feet tall. He climbs a ladder to paint some trim on his house. For each rung that he climbs, Brock is 1.2 feet high

kogti [31]

Since he is 6 feet tall, he starts with 6 feet above the ground and adding 1.2 each rung that he clibs so..y=mx+b ..m=slope.. b=started with...y=1.2x+6

Solve by using the quadratic formula: x2 - 6x + 7 = 0

IgorC [24]

Final Answer: $x = 3 + \sqrt{2}, 3 - \sqrt{2}$

Steps/Reasons/Explanation:

Question: Solve by using the quadratic formula: $x^{2} - 6x + 7 = 0$ .

Step 1: Use the Quadratic Formula.

$x = \frac{6 + \sqrt[2]{2} }{2}, \frac{6 - \sqrt[2]{2} }{2}$

Step 2: Simplify solutions.

$x = 3 + \sqrt{2}, 3 - \sqrt{2}$

~I hope I helped you :)~ The quadratic formulaic is attached in an image.

Answer:

(b) Mr. Sánchez's class earned more money.

(a) $\displaystyle [42, 37] → [j, p]$

Step-by-step explanation:

{79 = p + j

{118,17 = 1,65p + 1,36j

−25⁄34[118,17 = 1,65p + 1,36j]

{79 = p + j

{−86 121⁄136 = −1 29⁄136p - j >> New Equation

__________________________

$\displaystyle \frac{-7\frac{121}{136}}{-\frac{29}{136}} = \frac{-\frac{29}{136}p}{-\frac{29}{136}}$

$\displaystyle 37 = p$ [Plug this back into both equations above to get the j-value of 42]; $\displaystyle 42 = j$

The next step is to plug the solution into the BOTTOM EQUATION to calculate the total money earned for each class:

Sánchez's class

$\displaystyle 61,05 = [37][1,65]$

Altogether, thirty-seven fruit pies cost $61,05.

Kelly's class

$\displaystyle 57,12 = [42][1,36]$

Altogether, forty-two bottles of fruit juice cost $57,12.

* Based on the calculation, it is perfectly clear that Mr. Sánchez's class earned more money by $3,93:

$\displaystyle 3,93 = -57,12 + 61,05$

Can someone help ?? please

The y-intercept is the starting point. Since the temperature started at -7, we know that b in y = mx + b has to be -7. m is the slope which in our case is 3 because the temperature is changing every hour. So, because the temperature is going up, it's +3. Our equation should be y = 3x - 7.
