Please help me with this ​
e-lub [12.9K]

Answer:

7. 5 \frac{5}{8} pizza

8. B

9. 11 \frac{1}{5} inches

10. -12

11. \frac{3}{20}

12. 4

Step-by-step explanation:

7. 3 \frac{1}{2} \\ + 2 \frac{1}{8}

make them mixed fractions: \frac{7}{2} + \frac{17}{8}

get a common denominator by multiplying \frac{7}{2} by 4: \frac{28}{8} + \frac{17}{8}

add the numerators: \frac{45}{8}

simplify the fraction by dividing 45 by 8: 5 \frac{5}{8}

8. 3 x 6 = 18

5 x 6 = 30

7 x 6 = 42

9 x 6 = 54

therefore, y = 6x

9. 5:7 is similar to 8:L

divide 8 by 5: 1 \frac{3}{5}

multiply 7 by 1 \frac{3}{5}: 11 \frac{1}{5}

L = 11 \frac{1}{5} inches

10. 5 - 2x = 29

subtract 5 from each side: -2x = 24

divide each side by -2: x = -12

11. fruit = 15%

15% = 15/100

simplify by dividing by 5: \frac{3}{20}

12. the y-intercept is where the line crosses the y-axis (the vertical one). the line crosses the y-axis at 4.

Find the value of x.
Firlakuza [10]

Answer:

x=34 degrees

Step-by-step explanation:

since angle TSU=4x then angle RSP=4x

4x-3x=x

angle PSQ=x

angle PQS=112 degrees (180-68=112)

triangle PSQ angles are x+x+112=180

2x-68

x=34 degrees

Is g(x)=4+x^2/1+x^4 even, odd or neither
UkoKoshka [18]

Since g(-x) is equal to g(x), the function is an EVEN FUNCTION.

<h3>Is the given function even, odd or neither?</h3>

Given the function in the question;

g(x) = (4 + x²)/(1 + x⁴)

To determine if the function is even, odd or neither, we find g(-x) by substituting -x for all occurrence of x in the function.

g(x) = (4 + x²)/(1 + x⁴)

g(-1) = (4 + (-x)²)/(1 + (-x)⁴)

Simplify

g(-x) = (4 + x²)/(1 + x⁴)

Hence,

g(-x) = g(x)

Since g(-x) is equal to g(x), the function is an EVEN FUNCTION.
