Answer these for me please pretty please
anzhelika [568]

Answer:

1. t = 48.654

2. x = \frac{8}{3}

3. s = \frac{49}{4}

4. y = \frac{19}{12}

Step-by-step explanation:

To solve equations using variables, perform inverse operations to undo each part and isolate the variable.

1. \frac{t}{5.4} =9.01

Multiply by 5.4 on both sides to undo division.

t = 9.01 * 5.4

t = 48.654

2. \frac{3}{4}x = 2

Multiply both sides by the reciprocal of 3/4 which is 4/3.

x = 2*\frac{4}{3} \\x = \frac{8}{3}

3. s + \frac{1}{4} = 12\frac{1}{2}

Convert 12 1/2 into an improper fraction.

s + \frac{1}{4} = \frac{25}{2}

Subtract 1/4 from both sides.

s + \frac{1}{4} - \frac{1}{4}  = \frac{25}{2} - \frac{1}{4}

To subtract fractions without common denominators, convert 25/2 into a fraction with denominator of 4.

s = \frac{50}{4} - \frac{1}{4}\\s = \frac{49}{4}

4. 2\frac{2}{3} + y = 4 \frac{1}{4}

Subtract 2 2/3 from both sides.

2\frac{2}{3} - 2\frac{2}{3}  + y = 4 \frac{1}{4}- 2\frac{2}{3}

Convert each fraction into improper fractions and then to common denominators.

y = \frac{17}{4} - \frac{8}{3}\\\\ y = \frac{51}{12} - \frac{32}{12} \\\\y = \frac{19}{12}

What are the key aspects of the graph of f(x) = x2 – b2, where b is a real number?
netineya [11]

Given equation is f\left(x\right)=x^2-b^2.

Now we need to find about what are the key aspects of the graph of f\left(x\right)=x^2-b^2, where b is a real number.

We know that square of any number is always positive.

then b^2 must be a positive number.

So that means for any real number b, as the value of b increases then graph of f(x) shifts downward by b^2 units as compared to the graph of parent function f\left(x\right)=x^2
