Given the function f(x)=10x-3, what is the value of the function when x=-1/2

Answer:

[tex]f(x) = 5x \\ f(3) = 5(3) = \boxed{15}[/tex]

Answer:

x = 40

Step-by-step explanation:

x/(2 1/2) = 16/1

x/(5/2) = 16

Multiply both sides by 5/2.

x = 16 * 5/2

x = 80/2

x = 40

Answer: x = 40

Answer:

[tex]3(2x + 1) = 5(x -4) \\ 6x + 3 = 5x - 20 \\ 6x - 5x = - 3 - 20 \\ \boxed{x = - 23}[/tex]

Answer:

ANSWER WILL BE

E 2\5 × 3/4

Answer:

B, C and E

Step-by-step explanation:

The area of the shaded section above is [tex]\frac{24}{80}[/tex], which means 24 boxes out of 80 are shaded. It can be reduced to its lowest term:

Now, that we know the lowest term, we have to look for similar fractions based on the product for each choice.

A. [tex]\frac{5}{8}[/tex] x[tex]\frac{5}{10}[/tex] = [tex]\frac{25}{80}[/tex] or [tex]\frac{5}{16}[/tex]

B. [tex]\frac{4}{10}[/tex] x [tex]\frac{6}{8}[/tex] = [tex]\frac{24}{80}[/tex] or [tex]\frac{3}{10}[/tex]

C. [tex]\frac{3}{5}[/tex] x [tex]\frac{1}{2}[/tex] = [tex]\frac{3}{10}[/tex]

D. [tex]\frac{4}{8}[/tex] x [tex]\frac{4}{6}[/tex] = [tex]\frac{16}{64}[/tex] or [tex]\frac{1}{4}[/tex]

E. [tex]\frac{2}{5}[/tex] x [tex]\frac{3}{4}[/tex] = [tex]\frac{6}{20}[/tex] or [tex]\frac{3}{10}[/tex]

Answer: 71

Step-by-step explanation:

Answer:

x = 71°

Step-by-step explanation:

2x + 6 = 180° - 32°

2x + 6 = 148°

2x = 142°

x = 71°

Answer: x = 4

Step-by-step explanation:

since it is showing us that the angles are congruent, we know that the smaller triangle is just a scaled-down version of the larger one. in other words, it is the EXACT SAME triangle, just slightly smaller.

so, i redrew them next to each other, so i could compare them easily.

i looked at the corresponding sides that were given, and realized that the side that is 10 on the larger triangle is equal to 5 on the smaller triangle. the side that is equal to 6 on the larger triangle is equal to 3 on the smaller triangle. this concludes that the smaller triangle is exactly half the size of the larger triangle!

so, i figured (using logic) that x must equal 4, simply dividing its corresponding side (with a measure of 8) in half.

hope this helps! xoxo

Answer:

Population function (Based on 2007) =  7,600 + 700n

Step-by-step explanation:

Given:

Population in 2009 = 9,000

Population in 2014 = 12,500

Computation:

Increase in population per year = [12,500 - 9,000] / 5

Increase in population per year = 700

Population in 2007 = 9,000 - [2 x 700]

Population in 2007 = 7,600

Population function (Based on 2007) =  7,600 + 700n

n = number of year

Answer:

p(t)=700t+7600

Answer:

c=5,x=18/5 or 3.6

Step-by-step explanation:

Answer:

x=180

Step-by-step explanation:

Step-by-step explanation:

the equation completed is

1/2 (104 + 256) = 180

104+256 is 360.

360 multiplied by 1/2 (or 0.5) is 180.

Answer:

a or the first one

Step-by-step explanation:

x - 1 ≤ 6

add 1 to both sides

x ≤ 7

the ≤ is pointing <<< that way

so the line will go on the left side of seven

and since its greater than or equal to its a closed circle

Answer:

B

Step-by-step explanation:

sorry, I already commented about this because i couldnt find the answer button lol sorry, anyways I used a debt calculator to work it out

Answer:

error occurred in Step 1 because 2/3 and 1/4 should have been multiplied instead of added; so answer would be x^1/6

Answer:

150

Step-by-step explanation:

Angle FBA is 60 and angle ABC is 90, a line is 180 degrees so 180-30 = 150

Answer:

Line 1: Undefined

Line 2: -4/3

Line 3: 4/3

Line 4: Undefined

Line 5: 7/3

Line 6: -7/3

Line 7: 0

Line 8: 0

Line 9: Undefined

Line 11: 0

Line 10 & 12: Undefined

Step-by-step explanation:

Use the slope formula (you can just search up the slope formula)

Also, always remember that a vertical line's slope will be undefined and a horizontal line's slope will be 0 (zero).

I hope this helps!

Answer: 36

Step-by-step explanation: If you're asking what the expression equals after plugging X's value in, this should leave you with an expression of -3^2 - 5(-3) + 12. By following the order of operations, you should receive an answer of 36.

Answer:

B (-1, 0)

Step-by-step explanation:

( in portuguese )

o ponto médio é calculado pela soma das abcissas a dividir por 2 e pela somas das ordenadas a dividir por 2, então sendo que se sabe o valor final, e um ponto fica :

(1+x)÷2 = 0 ⇔ x = -1

(1 + y) ÷ 2 = 1/2⇔ y=0
