Answer:
The standard form of y = 3 x + 1 is -3x + y = 1 .
The standard form of y = 4x - 7 is -4x + y = -7.
Step-by-step explanation:
Here the given equation are:
y = 3 x + 1
and y = 4x - 7
The above equations are of the form: y = m x + C
Now, the STANDARD FORM of the equation is Ax + By = C
<u>Consider equation 1: </u>
y = 3 x + 1
or, y - 3x = 1
or. -3x + y = 1
⇒ The equation -3x + y = 1 is in STANDARD FORM.
<u>Consider equation 2: </u>
y = 4 x - 7
or, y - 4x = -7
or. -4x + y = -7
⇒ The equation -4x + y = -7 is in STANDARD FORM.
Answer:
Step-by-step explanation:
a)
- 1.5x² + 6x + * =
- 1.5(x² + 4x + *) =
- 1.5(x² + 2*2x + 4) =
- 1.5(x + 2)²
- * = 1.5*2² = 6
b)
- 2x² - 5x + * =
- 2(x² - 2.5x + *) =
- 2(x² - 2*1.25x + 1.25²)=
- 2(x - 1.25)²
- * = 2*(1.25)² = 3.125 or 25/8

Step-by-step explanation:
Answer:
He earns 749 dollars.
Step-by-step explanation:
I multiplied the money he earns per day ($75) to each day he works (5 days) and I got 375 , but I also multiplied how much he get paid to install windows ($8) to how many he installs every 5 days and I got 374 , and Then I added up 374 and 375 and that's how I got 749 . Plzz correct me if I'm wrong .
