A number plus 1 is greater than -5 and less than three.
define a variable, write an inequality.

Answer:

Step-by-step explanation:

Replace x with -5

2(-5)+7

-10+7

-3

Answer:

-3

Step-by-step explanation:

Evaluate 2 x + 7 where x = -5:

2 x + 7 = 7 - 5×2

Hint: | Multiply 2 and -5 together.

2 (-5) = -10:

-10 + 7

Hint: | Subtract 10 from 7.

7 - 10 = -3:

Answer: -3

Answer: No, it is not a function

Why not? Because the graph fails the vertical line test. It is possible to draw a single vertical line through more than one point on the graph. For instance, we can draw a vertical line through x = 1 on the x axis, and this vertical line crosses the curve at two different points.

A function is only possible if any input x leads to exactly one y output.

A graph may or may not represent a function depending on the relationship between the x and y values of the graph.

The given graph does not represent a function

From the graph, we observe that;

The same value of x points to the different values of y.

For instance:

[tex](x,y) \to (-6,3)[/tex]

[tex](x,y) \to (-6,-3)[/tex]

When x = -6, the values of y are 3 and -3.

This is a many-to-one relation.

And a many-to-one relation does not represent a function.

Also, from the graph; there are several other values of x, that point to multiple values of y

Hence, the graph does not represent a function.

Answer:

Slope = 7

Y-intercept = 4

Step-by-step explanation:

the equation follows the formula of y=mx+b

m = slope

b = y-intercept

Answer:

slope = 7, y- intercept = 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 7x + 4 ← is in slope- intercept form

with slope m = 7 and y- intercept c = 4

Step-by-step explanation:

let point that BD intersects extended A be Z

angle BDA = 180 - 56 - 78 = 46 deg (supplementary angle in //ogram)

angle AZD = 180 - 98 = 82 deg (angles on a straight line/supplementary angles on straight line)

therefore,

angle x = 180 - 82 - 46 = 52 deg (sum angles of triangle)

=======================================================

Explanation:

We'll use these two log rules

So,

log(2x) + log(x-1) = log(6x)

log[ 2x*(x-1) ] = log(6x) ...... use rule 1

2x*(x-1) = 6x ...... use rule 2

2x^2-2x = 6x

2x^2-2x-6x = 0

2x^2-8x = 0

2x(x-4) = 0

2x = 0 or x-4 = 0

x = 0 or x = 4

The two possible solutions are x = 0 or x = 4. However, we must check both possible answers because some or all of them may be extraneous.

-----------------------------------

Checking x = 0

log(2x) + log(x-1) = log(6x)

log(2*0) + log(0-1) = log(6*0)

log(0) + log(-1) = log(0)

We run into a roadblock. We cannot take the log of 0 or anything negative. The domain of y = log(x) is x > 0. So we cross x = 0 off the list.

Now let's check x = 4

log(2x) + log(x-1) = log(6x)

log(2*4) + log(4-1) = log(6*4)

log(8) + log(3) = log(24)

log(8*3) = log(24)

log(24) = log(24)

We've confirmed x = 4. This is the only solution.

Answer:

0.75 g/cm^3 to 2 decimal places.

Step-by-step explanation:

Density = mass / volume

= 140 / 182

= 0.7487 g/cm^3

hope this helped

Answer:

[tex]\boxed {\boxed {\sf d \approx 0.75 \ g/cm^3}}[/tex]

Step-by-step explanation:

Density can be found by dividing the mass by the volume.

[tex]d=\frac{m}{v}[/tex]

The mass of the block of cheese is 140 grams and the volume is 187 cubic centimeters.

[tex]m= 140 \ g \\v= 187 \ cm^3[/tex]

Substitute the values into the formula.

[tex]d=\frac{140 \ g}{187 \ cm^3}[/tex]

Divide.

[tex]d=0.748663102 \ g/cm^3[/tex]

Round to the hundredth place (2 decimal places).

The 8 in the thousandth place tells us to round the 4 to a 5.

[tex]d \approx 0.75 \ g/cm^3[/tex]

The density is about 0.75 grams per cubic centimeters.

7 and 8.2

Step-by-step explanation:

Let the number be x

Translating the word problem into an algebraic equation;

[tex] 7 + 5x = 48[/tex]

[tex] 5x = 48 - 7 [/tex]

[tex] 5x = 41[/tex]

[tex] x = \frac {41}{5} [/tex]

x = 8.2

Therefore, the two numbers are 7 and 8.2

Check;

7 + 5(8.2) = 7 + 41 = 48

y=15-x

If you want to solve for y, you need another one equation

Answer:

y = -x + 15

Step-by-step explanation:

Subtract 3x from each side (left and right side of the equal sign) which will leave you with 3y = -3x + 45. Then divide everything by 3 which gets you

y = -x +15
