Step-by-step explanation:

Remark

The two angles across from each other are equal.

Equation

5x - 1 = 124                  Add 1 to both sides

Solution

5x - 1  + 1 = 124 + 1      Combine

5x = 125                      Divide by 5

5x/5 = 125/5

x = 25                

Answer:

b = 12

Step-by-step explanation:

First, distribute 3/4 to both terms in the parentheses:

3 = 3/4(b - 8)

3 = 3/4b - 6

Now, solve for b:

9 = 3/4b

12 = b

So, the answer is b = 12

Answer:

12

Step-by-step explanation:

3 = 3/4 x (b-8)

Distribute 3/4 through the parentheses

3 = 3/4 b - 6

Multiply both sides of the equation by 4

12 = 3b - 24

Move the variable to the left - hand side and change its sign

-3b = -24 - 12

Calculate the difference

-3b = -36

Divide both sides of the equation by -3

B = 12

Answer:

Day 1=15 Day 2=30 Day 3=45 Day 4= 60 Day 5= 75. The expression is N+15

Step-by-step explanation:

The complete table:

Days                  1    2     3    4     5

Total samples  15  30  45  60   75

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of bacteria samples analyze each day = 15

The equation for the number of bacteria analyzes after x days.

B = 15x

Now,

x = 1, B = 15

x = 2, B = 30

x = 3, B = 45

x = 4, B = 60

x = 5, B = 75

Thus,

Days                  1    2     3    4     5

Total samples  15  30  45  60   75

9. Sobre o estudo de equações, escreva V para as afirmações verdadeiras e F para as falsas.

a) ( ) A expressão 17 - 4x + 25 representa uma equação.

b) ( ) O número 23 representa um dos membros da equação -9x + 4 = 23.

c) ( ) Na equação x + 4 = 3x + 20, a incógnita é x.

d) ( ) A equação 3y - 15 = 0 não tem segundo membro.

Answer:

(2, -3) → (2, 3) reflection across the x-axis

(2, -3) → (-2, -3) reflection across the y-axis

(2, -3) → (-2, 3) reflection across both axes

(2, -3) → (-3, 2) not a reflection

Step-by-step explanation:

Reflection across the x-axis:

When we reflect a point across the x-axis, it's x coordinate keeps the same value, while the signal of the y-coordinate is changed, having the same value, with different signal.

So the correct option is:

(2, -3) → (2, 3) reflection across the x-axis

Reflection across the y-axis:

When we reflect a point across the y-axis, it's y coordinate keeps the same value, while the signal of the x-coordinate is changed, having the same value, with different signal.

So the correct option is:

(2, -3) → (-2, -3) reflection across the y-axis

Reflection across both axis:

Both change the signal. So

(2, -3) → (-2, 3) reflection across both axes

Rotations:

When we have a rotation, not only the signals can change, but also the numbers, x with y and y with x. Rotations are not reflections. So

(2, -3) → (-3, 2) not a reflection

Step-by-step explanation:

First convert 1/2 into eights. 1/2 as eighths is 4/8.

So 4/8-1/8=3/8.

Therefor, 3/8 is the answer you're looking for.

I hope I helped :)

Answer:

3/8

Step-by-step explanation:

you have to find the LCM (least common multiplier) of 2,and 8 and that would be 8 therefore youd change the fractions from 1/2-1/8 to 4/8-1/8  you subtract the tops and keep the bottoms the same as 8. so 4-1=3 therefore the anwser would be 3/8

Answer:

y intercept: (0,1)

Axis of symmetry: x=-2

Step-by-step explanation:

The y intercept is where the curve crosses the y axis.

y intercept: (0,1)

The axis of symmetry is the x value where drawing a vertical line has the left side of the curve a mirror image of the right side of the curve.

Axis of symmetry: x=-2

The required y-intercept is (0, 1) and the axis of symmetry is x = -2. Options A and C are correct.

In the equation intercept is the value of the linear function where either of the variables is zero.

Here,
From the above definition in the graph locate the value of y when x is zero,
So, in the graph, when x is zero y is 1
There is why the y-intercept of the given function is 1,

Now,
For the axis of symmetry, just draw a line with a vertex that part the function in two equal halves,
So vertex of the given function is (-2, -3), and the line that divides the function in two equal halves is x = -2

Thus, Options A and C are correct.

An equilateral triangle means all sides are the same.

Answer:

68 and 70

Step-by-step explanation:

if the first integer is x, the next would be x + 2

so your equation is x + x+2 = 138

2x + 2 = 138

minus 2 on both sides

2x =136

x = 68

so if x is 68

x + 2 would be 70

if you add those up, im pretty sure you'll get 138

Answer:

a=22

Step-by-step explanation:

2a+2=46

2a=46-2

2a=44

a=44÷2

a=22

Answer:

a = 22°

Step-by-step explanation:

Since vertical angles are always congruent we know that 46° = 2a + 2°, therefor...

46° = 2a + 2°

2a = 46° - 2°

2a = 44°

a = 44° / 2

a = 22°
