If y = x 2 - 4 is being graphed using the table method, what is the y-value generated when x = - 2 ?

Arada [10]

Answer:

(There's a confusion here, is x 2 x times 2? The answer and explanation are based on x multiply by 2)

y = -8

Step-by-step explanation:

Substitution Method-

y = x 2 - 4

x = -2

y = (-2) 2 - 4

PEMDAS - parentheses; exponents; Multiplication & Division; Addition & Subtraction

we are going to multipl -2 and 2 together ---> -4

y = -4 - 4

Same sign add, different sign subtract.

Same sign keep the sign, different sign keep the larger.

y = -8

Please mark brainliest!

Hope this helps!

Thank you,

Have a great day!

Which fraction is equivalent to 7/15? A. 14/28 B. 14/17 C. 21/45 D. 21/35

Leto [7]

C. 21/45

If you multiply both the 7 and 15 by 3, you get 21 and 45.

$\frac{7}{15} × \frac{3}{3} = \frac{21}{45}$

Calculate the side lengths a and b to two decimal places.

navik [9.2K]

Answer:

D. a = 11.71 and b = 15.56

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Trigonometry

All angles in a triangle add up to 180°

Pre-Calculus

Law of Sines: $\frac{sin(A)}{a} =\frac{sin(B)}{b} =\frac{sin(C)}{c}$

Step-by-step explanation:

Step 1: Define

AC = b

CB = a

AB = 7

m∠A = 45°

m∠B = 110°

m∠C = ?

Step 2: Find missing ∠

Set up equation: m∠C + 45° + 110° = 180°
Combine like terms: m∠C + 115° = 180°
Isolate unknown: m∠C = 25°

Step 3: Find measure of b

Substitute: $\frac{sin(25)}{7} =\frac{sin(110)}{b}$
Cross-multiply: $bsin(25)=7sin(110)$
Isolate b: $b=\frac{7sin(110)}{sin(25)}$
Evaluate: $b=15.5645$
Round: $b \approx 15.56$

Step 4: Find measure of a

Substitute: $\frac{sin(25)}{7} =\frac{sin(45)}{a}$
Cross-multiply: $asin(25)=7sin(45)$
Isolate a: $a=\frac{7sin(45)}{sin(25)}$
Evaluate: $a=11.7121$
Round: $a \approx 11.71$
