The graph of linear function f passes through the point (1, -9) and has a slope of -3. What is the zero of f ?
den301095 [7]

Answer:

-2

Step-by-step explanation:

The standard equation of a line is y = mx+c

m is the slope

c is the intercept

Given

Slope = -3

Get the intercept c;

Substitute m = -3 and (1, -9) into y = mx+c

-9 = -3(1) + c

-9  = -3 + c

c = -9 + 3

c = -6

The equation becomes

y = -3x + (-6)

y = -3x-6

f(x) = -3x-6

The zero of f occurs at f(x) = 0

0 = -3x-6

3x = -6

x = -6/3

x = -2

Hence the zero of the function is -2

Rebecca bought a square table for her kitchen. The area of the table’s surface is 65 ft • 2 What is the approximate length of on
rodikova [14]

Answer:

<h2> 8.06ft</h2>

Step-by-step explanation:

step one:

This problem is on the mensuration of solids,

given that the area is 65ft^2

step two:

we know that the expression for the area of a solid is

areaa= length* length

area= l^2

step three:

substituting the value of the area into the expression we have

65=l^2

we need to square both sides to solve for l we have

√65=l

l= 8.05ft

step four:

From the analysis we found the length of one side to be 8.06ft

If Angle A = 5x-10, find the value(s) for x that would ensure that Angle A was an obtuse angle.
morpeh [17]

Answer:

20 < x < 38.

Step-by-step explanation:

An obtuse angle has a value between 90 and 180.

90 < 5x - 10 < 180

5x - 10 > 90

5x > 100.

x > 20.

5x - 10< 180

5x < 190

x < 38
