Mathematics
1 answer:
sweet [91]3 years ago
7 0

Answer:

m=4

Step-by-step explanation:

11m - 15 -5m= 9

Combine like terms

6m -15 =9

Add 15 to each side

6m - 15+15 = 9+15

6m = 24

Divide each side by 6

6m/6 =24/6

m = 4

Which of the following is the equation of the quadratic function below?
exis [7]

Answer:

A. y = x² - 9x + 18

Step-by-step explanation:

The key thing to look for in this graph is the <u>y-intercept</u> (where the graph will hit the y-axis).

We can't see exactly where y-intercept is, but we know it is a positive number.

In a standard form quadratic equation:

<em>y = ax² + bx + <u>c</u></em>

'<em>c</em>' tells you what the y-intercept is.

The choices with positive y-intercept are <u>A</u> and <u>B</u>.

Again, we can't see exactly where y-intercept is, but we know it is not 1.

y = x² - 9x + 18

has a positive y-intercept that is not 1,

thus the answer is A.

Consider a line whose slope is 6 and which passes through the point (8.–2).
Zolol [24]

Answer:

y=6(x-8)-2\qquad\text{point-slope form}

y=6x-50\qquad\text{slope-intercept form}

Step-by-step explanation:

The equation of a line can be written in several forms. Two of the most-used forms are the point-slope and the slope-intercept forms.

The point-slope form requires to have one point (xo, yo) through which the line passes and the slope m. The equation expressed in this form is:

y=m(x-xo)+yo

The slope-intercept form requires to have the slope m and the y-intercept b, or the y-coordinate of the point where the line crosses the y-axis. The equation is:

y=mx+b

The line considered in the question has a slope m=6 and passes through the point (8,-2). These data is enough to find the point-slope form of the line:

\boxed{y=6(x-8)-2\qquad\text{point-slope form}}

To find the slope-intercept form, we operate the above equation:

y=6x-48-2

\boxed{y=6x-50\qquad\text{slope-intercept form}}
