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:

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.

Answer:

A and C

Step-by-step explanation:

The equivalent expressions are:

3(p + 5) and 7p - 4p + 15

Options A and C are the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

3p + 15

Taking out common factors.

3 (p + 5)  ____(1)

And,

7p - 4p + 15

3p + 15

3(p + 5) _____(2)

From (1) and (2),

3(p + 5) and 7p - 4p + 15 are equivalent expression.

Thus,

The equivalent expressions are:

3(p + 5) and 7p - 4p + 15

Hi there!

Convert 36 into 35 and 4/4 since if it is just a number, it can’t be multiply by 3/4.

[tex]36= 35 \frac{4}{4}[/tex]

Multiply both fractions now but also turn 35 4/4 into a mixed number:

[tex]36=\frac{144}{4}[/tex]

[tex]\frac{3}{4} x \frac{144}{4}= \frac{27}{1} = 27[/tex]

Final Result: 27

Answer:

19/24 = 0.791666667

Step-by-step explanation:

7/8 - 1/12

Least common multiple of 8 and 12 is 24. Convert 7/8 and 1/12 to fractions with denominator 24.

21/24 - 2/24

Since 21/24 and 2/24 have the same denominator, subtract them by subtracting their numerators.

21 - 2 / 24

Subtract 2 from 21 to get 19.

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

Answer:

[tex]\lambda=10^{-10}\ m[/tex]

Step-by-step explanation:

Given that,

The frequency of x-rays, [tex]f=3\times 10^{18}\ Hz[/tex]

We need to find the wavelength for x-rays. The relation between wavelength, frequency and speed of light is given by :

[tex]v=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^{8}}{3\times 10^{18}}\\\\=10^{-10}\ m[/tex]

So, the wavelength for x-rays is [tex]10^{-10}\ m[/tex].

Answer:

1x 10-10 m

Step-by-step explanation:

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

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°

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
