I need help please (brainllest)

Answer:

1) 3x = 39  ; x = 39/3 = 13

2) x + 7 = 15 ; x = 15-7 = 8

3) 6x = 18  ; x = 18/6 = 3

4) x-4 = 11  ; x = 11 + 4 = 15

5) 1/7 x = 3   ;  x = 3 *7 = 21

6) 13+x = 21  ;  x = 21 - 13 = 8

I hope im right!!!

Graphing functions is the process of drawing a curve on the reference system that represents a function, and its calculation can be defined as follows:

Graph function:

[tex]\to F(x)=\frac{3}{8} (x-1)(x-9)[/tex]

solving the above given function:

[tex]\to F(x)=\frac{3}{8} (x^2 -9x-x+9)\\\\\to F(x)=\frac{3}{8} (x^2 -10x+9)\\\\\to F(x)=\frac{3}{8} \times x^2 - \frac{3}{8} \times 10x+ \frac{3}{8} \times 9\\\\\to F(x)=\frac{3}{8} \times x^2 - \frac{3}{4} \times 5x+ \frac{3}{8} \times 9\\\\[/tex]

Please find the graph function in the attached file.

Answer:

It only has one solution.

Step-by-step explanation:

4x-20= -2 (-2x + 10)

Add 20 to both sides

4x-20+20=4x-20+20

simplify:

4x=4x

Subtract 4x from both sides

4x-4x=4x-4

Simplify:

0=0

Answer:

1. Yes

2. No

2. Yes

4. Yes

5. Yes

Step-by-step explanation:

The angles in the first pair are congruent and 40° each (XYZ and XYW are complementary)

Segment FG is 4 cm while segment DE is 6 cm so they are not congruent

As shown on the figure both segment OR and segment OS is 2 in. long

Angle 2 and angle 4 are congruent

Angle ROQ and angle ROP are congruent because all angles shown on the figure has a measure of 90°

Answer:

Answer:

The Correct Answer Is C

Step-by-step explanation:

For The triangles have the same angles which checks out and the side sides, if say you simplified the sides or whatever

Therefore, its C

Hope I Helps!

Answer:

Step-by-step explanation:

Given triangles A, B and C

Triangles A and C have congruent angles of 23° and 67° and similar sides with the scale factor of 3.

Triangle B is different, with angles 28° and 62°, therefore can't be similar to A or C.

Correct choice is C

The expression 76a²b³ / 19ab is equivalent to the expression 4ab².

The equivalent is the expressions that are in different forms but are equal to the same value.

The expression is given below.

⇒ 76a²b³ / 19ab

Then the expression can be written as

⇒ 4ab²

Then the expression 76a²b³ / 19ab is equivalent to the expression 4ab².

Answer:

  x = 12

Step-by-step explanation:

The two marked angles are a linear pair, so are supplementary.

  (8x -20)° +(8x +8)° = 180°

  16x -12 = 180 . . . . . . . . . . . divide by °, collect terms

  16x = 192 . . . . . . . . . . . add 12

  x = 12 . . . . . . . . . . . divide by 16

Answer:

Step-by-step explanation:

-x + 10 = 40

-x = 40 - 10

-x = 30

x = - 30

-3x + 4 = 10

-3x = 10 - 4

-3x = 6

x = 6/-3

x = - 2

Answer:

x=-30 for A

Step-by-step explanation

subtract both sides by 10 which means 40-10=30

then add the negative sign

Answer:

9 is the largest number of baskets they can make and still have enough muffins.

Step-by-step explanation:

If they want to use all three types of muffins for the basket, they’d have to find the GCF (greatest common factor) of 30, 54, and 27, which is 9. They’d still have a lot left over... but if they want to put all three types of muffins then they can only make 9 full baskets.

Step-by-step explanation:

pythagorean theorem

take the sum of the square of each leg and set it equal to the square of the hypotenuse

8² + 6² = x²

64 + 36 = x²

x² = 100

x = [tex]\sqrt{100}[/tex] or 10

Answer:

B.10 units

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem which states that a^2+b^2=c^2

Plug in what we know....

8^2+6^2=c^2

64+36=c^2

c=sqrt(100)

c=10 units or B

Answer:

y=-5/2x+4

Step-by-step explanation:

find the slope by using y2-y1/x2-x1

-1-19/2-(-4)

simplify

-20/8

simplify

-5/2

use slope-intercept form, y=mx+b

since we know the slope, find b

plug in one of the ordered pairs into the equation

-1=(-5/2)(2)+b

simplify

-1= -10/2+b

simplify

-1=-5+b

add 5 to both sides

b=4

plug b into y=-5/2x+b

y=-5/2x+4
