Find three points and then graph: y 3/4x-1

Answers

Answer 1

Answer: y = 3/4x - 1
to find points, plug in a value for x and solve for the y.

i'm going to start with x =4, and solve for a y

y = 3/4(4) -1
y = 3 - 1
y = 2

The point is (4,2)

Find two other values by choosing two other x values and then you can graph the line

Hope this helps!

Answer 2

Answer: $y= (3)/(4)x-1\n\ny=0\ \ \to\ \ (3)/(4)x-1=0\ \ | \ add\ 1\ to\ both\ sides\n\n \frac{3} {4}x=1\ \ | \ multiply\ both\ sides\ by\ (4)/(3) \n\nx= (4)/(3)\n( (4)/(3),0)\n\n x=0\ \ \to\ \ y= (3)/(4)*0-1=-1\n(0,-1)$

Evaluate: 20 - {3 × 8 - 5 - (3 - 25 ÷ 5)}

Answers

Answer:

Step-by-step explanation:

To evaluate the expression 20 - {3 × 8 - 5 - (3 - 25 ÷ 5)}, follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right):

Inside the innermost parentheses, we have:

3 - 25 ÷ 5

= 3 - 5

= -2

Now, the expression becomes:

20 - {3 × 8 - 5 - (-2)}

Next, perform the multiplication and subtraction inside the innermost braces:

3 × 8 = 24

5 - (-2) = 5 + 2 = 7

The expression becomes:

20 - {24 - 7}

Continue inside the braces:

24 - 7 = 17

Now, the expression becomes:

20 - 17

Finally, subtract:

20 - 17 = 3

So, the value of the expression is 3.

Following the steps of the BODMAS rule, the expression simplifies to -1.

The question involves arithmetic operations such as subtraction, multiplication, and division. The correct order of these operations is dictated by the BODMAS rule, which stands for Brackets, Orders (powers and square roots, etc.), Division and Multiplication (left-to-right), Addition and Subtraction (left-to-right).

According to this rule, begin by calculating within the deepest set of brackets: 25 ÷ 5 = 5. Your expression now becomes: 20 - {3 × 8 - 5 - (3 - 5)}, which simplifies to 20 - {3 × 8 - 5 - -2}. The next step is to calculate the multiplication: 24 - 5 - -2, which further simplifies to 20 - {24 - 5 + 2}, which becomes 20 - {21}, leading to a final result of -1.
