Hello! Here is a real world problem that could work:

Jennie currently has $5 in her allowance. For every time she helps cook dinner, she earns $2. Jennie wants to buy an art set that costs $23, before tax. How many times would she have to help with dinner, before she could buy the art set?

How to solve it:

Okay. $5 is the fixed amount (one-time price), and Jennie earns $2 each time she helps cook dinner. First, let's subtract 5 from both sides in order to get 2x > 18. Now, divide each side by 2 to isolate the "x". 18/2 = 9. x > 9.There. Jennie would have to help cook dinner 9 times, before she has $23, but we are looking for greater than, so she would have to help 10 times, before she had enough money to buy the art set.

Amira is told there is a trick to finding the slope within an equation in standard form, Ax+By=C. She is told she can rewrite th
Advocard [28]

Answer:

B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.

Step-by-step explanation:

<u>Let's convert the standard equation into slope-intercept form:</u>

  • Ax + By = C              ⇒ subtract Ax from both sides
  • By = -Ax + C             ⇒ divide both sides by B
  • y = -A/Bx + C/B        ⇒ converted to slope- intercept form

As we see the slope is -A/B

<u>The equation 7x + 9y = 14 is converted as:</u>

  • y = -7/9x + 14/9, where the slope is -7/9

<u>Looking at the answer options and the correct one is option B, where both identification of slopes match.</u>

  • B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.

The tangent of the larger acute angle
Tems11 [23]

Answer: The tangent of the larger acute angle is 4/3 or 1⅓

Step-by-step explanation: if the sides of the right angled triangle are given as 3, 4 and 5 respectively, then the hypotenuse is 5 and the longer of the other two sides is 4. The angle facing the side measuring 4 is your reference angle, and that is the larger of the other two acute angles (see attachment)

Tan X = opposite/hypotenuse

Tan X = 4/3

Tan X = 1⅓
