Option C

The equation of the graph of [tex]f(x) = \sqrt x[/tex] is (d) on a coordinate plane, an absolute value graph starts at (0, 0) and goes up through (4, 2).

The equation of the graph is represented as:

See attachment for the graph of [tex]f(x) = \sqrt x[/tex]

From the attached graph, the curve passes through points (0,0) and (4,2).

Hence, the equation of the graph of [tex]f(x) = \sqrt x[/tex] is (d)

Step-by-step explanation:

Doubled of 132 which means 2 times 132 =

Subtract 12 doubled from 132

While write the expression whatever the expression after the word from that we have to write first

So Doubled of 132 - 12

- 12 -----> This is the final expression

If we simplify the above expression we will get

264 - 12

= 252

Answer:

2*(132-12)

Step-by-step explanation:

from 132 meaning its the biggest number or the number where operations act on.

subtract 12, so ignoring doubled, subtract 12 from 132 is 132-12,

doubled meaning x2 so its 2*(132-12)

SAS & SSS would require sides to be congruent (They aren't)
AA would require 2 angles to be congruent, and we don't have enough information to prove a 2nd angle would be congruent

Answer:

b SAS Similarity Theorem

BRAINLIEST, PLEASE!

Step-by-step explanation:

The triangles are both similar since they share an angle, and two of their side ratios are roughly the same. This is the SAS Similarity Theorem. (side, then angle, then side)

Answer:

x = -9

Step-by-step explanation:

Distribute

3(x+1)=-24

3+3=−24

Subtract 3 from both sides of the equation

3x+3=-24

3+3−3=−24−3

Simplify

3x =-27

Divide both sides of the equation by the same term

3x=-27

3/3=−27/3

Simplify

x = -9

Answer:

Neither increasing or descreasing

Step-by-step explanation:

Decreasing - slope of line is negative, e.g. y = -2x

Increasing - slop of line is positive, e.g. y = 2x

Vertical lines have no slope, so they are neither increasing or decreasing

6y + 2 = -4

y + 8 = -4

y = -4 -8

y = -12

answer : -12

Answer:

y = -1

Step-by-step explanation:

Subtract 2 from both sides of the equation

6y+2=-4

6y+2-2=-4-2

Simplify

6y=-6

Divide both sides of the equation by the same term

6y/6=-6/6

Step-by-step explanation:

Answer:

this looks like a rectangle with a right triangle cut out of it.

first we need the area of the rectangle (w*h).

4*8 = 32

32 - the area of the right triangle

triangle area = (wh)/2

4-2 (to find the smallest side of right triangle) = 2

and 8-4 (to find second largest side of right triangle) = 4

4*2 = 8

and 8/2 = 4

32 - 4 = 28

[tex](x-4)(x+9)[/tex]

Step-by-step explanation:

To factorize a quadratic equation, take into consideration that:

If [tex]ax^2+bx+c[/tex],

then [tex](x+w)(x+v)[/tex]

ONLY IF [tex]w+v=b[/tex] and [tex]wv=c[/tex].

To start, find factors of c, which in this case, -36:

1 and -36

2 and -18

3 and -12

4 and -9

6 and -6

-6 and 6

-4 and 9

-3 and 12

-2 and 18

-1 and 36

Try out which pair of numbers add up to b, which in this case, 5:

[tex]1+(-36)\neq 5\\2+(-18)\neq 5\\3+(-12)\neq 5\\4+(-9)\neq 5\\6+(-6)\neq 5\\-6+6\neq 5\\-4+9=5\\-3+12\neq 5\\-2+18\neq 5\\-1+36\neq 5[/tex]

The only pair of numbers that add up to 5 is -4 and 9, so:

[tex]x^2+5x-36\\=(x-4)(x+9)[/tex]

Answer:

x = 50

Step-by-step explanation:

[tex]\log _{10}\left(x\right)=\log _{10}\left(2x^2\right)-2[/tex]

[tex]\log _{10}\left(x\right)=\log _{10}\left(2x^2\right)-\log _{10}\left(100\right)[/tex]

[tex]\log _{10}\left(x\right)=\log _{10}\left(\frac{2x^2}{100} \right)[/tex]

[tex]x = \frac{2x^2}{100}[/tex]

[tex]100x=2x^2[/tex]

[tex]x^2 = 50x[/tex]

[tex]x = 50[/tex]
