Answer:

the answer is 7x + 437

Step-by-step explanation:

1) 7 is the only number with a variable, <em>x</em>, so it will remain as it is.

2) -4+4= 0

3)1+1= 2

4) 2+435= 437

7) combine 7x and 437 together. 7x + 437.

We cant go any further, because 7x and 437 are not liketerms.

A line passes through point A (14,21). A second point on the line has an x-value that is 125% of the x-value of point A and a y-

seropon [69]

Answer:

The equation of the line in point-slope form is $y-21 = - \frac{3}{2}\cdot (x-14)$ .

Step-by-step explanation:

According to the statement, let $A(x,y) = (14,21)$ and $B(x,y) = (1.25\cdot x_{A},0.75\cdot y_{A})$ . The equation of the line in point-slope form is defined by the following formula:

$y-y_{A} = m\cdot (x-x_{A})$ (1)

Where:

$x_{A}$ , $y_{A}$ - Coordinates of the point A, dimensionless.

$m$ - Slope, dimensionless.

$x$ - Independent variable, dimensionless.

$y$ - Dependent variable, dimensionless.

In addition, the slope of the line is defined by:

$m = \frac{y_{B}-y_{A}}{x_{B}-x_{A}}$ (2)

If we know that $x_{A} = 14$ and $y_{A} = 21$ , then the equation of the line in point-slope form is:

$x_{B} = 1.25\cdot (14)$

$x_{B} = 17.5$

$y_{B} = 0.75\cdot (21)$

$y_{B} = 15.75$

From (2):

$m = \frac{15.75-21}{17.5-14}$

$m = -\frac{3}{2}$

By (1):

$y-21 = - \frac{3}{2}\cdot (x-14)$

The equation of the line in point-slope form is $y-21 = - \frac{3}{2}\cdot (x-14)$ .

32x+5 = 3x - 3<br> Solving exponential equations

Likurg_2 [28]

Answer:

x = -8/29 = -0.276

Step-by-step explanation:

Step 1 :

Solving a Single Variable Equation :

1.1 Solve : 29x+8 = 0

Subtract 8 from both sides of the equation :

29x = -8

Divide both sides of the equation by 29:

x = -8/29 = -0.276

One solution was found :

x = -8/29 = -0.276
