−f+2+4f=8−3f

Add −f

and 4f

.

3f+2=8−3f

Move all terms containing f

to the left side of the equation.

Add −3f

to both sides of the equation.

3f+2+3f=8

Add 3f

and 3f

6f+2=8

Move all terms not containing f

to the right side of the equation.

Subtract 2

from both sides of the equation.

6f=−2+8

Add −2

and 8

6f=6

Divide each term by 6

and simplify.

Divide each term in 6f=6

by 6

6f6=66

Reduce the expression by cancelling the common factors.

f=66

Divide 6

by 6

f=1

-f + 4f + 2 = 8 - 3f

3f + 2 = 8 - 3f

6f = 6

f = 1

An engineer measures the peak current (in microamps) when a solution containing an amount of nickel (in parts per 106 ) is added
dangina [55]

Answer:

B. decrease the intercept, increase the slope

Step-by-step explanation:

A slope indicates the steepness of a line while the intercept points the location where it intercepts its axis. The linear relationship between can be defined using the intercept and the slope. Both concepts are used to estimate the average range of change. Since we are trying to add a peak current value of 0.38 which is lesser than the average, the intercept of the graph would therefore decrease and the slope increase.

What is the equation of a line with a x-intercept of −2 and a y-intercept of 10?
IceJOKER [234]

Hey there! :)

Answer:

y = 5x + 10

Step-by-step explanation:

From the information given, we can derive the points (-2, 0) and (0, 10). Find the slope using the slope formula:

m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}

Plug in the points:

m= \frac{10 - 0}{0 - (-2)}

Simplify:

m= \frac{10}{2}

m = 5.

The equation in slope-intercept form is y = mx + b. We were already given the b value, or y-intercept as y = 10. Therefore:

y = 5x + 10 is the equation written in slope-intercept form.
