A line that includes the points (9,j) and (10,4) has a slope of 1. What is the value of j?

Sergeu [11.5K]

Answer:

soln

A=(9,j)

x1=9,y1=j

B=(10,4)

x2=10,y2=4

slope=1

by using the fomulaof slope,

slope=y2-y1/x2-x1

1 =4-j/10-9

1 = 4-j/1

1=4-j

j=4-1

j=3

the measurements of a photo and it's frame are shown in the diagram. Write a polynomial that represents the width of the photo.

suter [353]

Answer:

The width of the photo is $4w^2+6w+4$ .

Step-by-step explanation:

From the given figure it is notices that the total width of the frame is

$6w^2+8$

The photo is covered by a frame border and the width of the border is

$w^2-3w+2$

To find the width of the photo we have to subtract the width of upper frame border and lower frame border from the total width of frame.

Width of the photo is

$\text{Width of the photo}=\text{Width of the frame}-2(\text{Width of the frame border})$

$\text{Width of the photo}=6w^2+8-2(w^2-3w+2)$

$\text{Width of the photo}=6w^2+8-2w^2+6w-4$

$\text{Width of the photo}=4w^2+6w+4$

Therefore the width of the photo is $4w^2+6w+4$ .

Find the value of 14/8 + 15/12

n200080 [17]

Answer:

The value of $\frac{14}{8} + \frac{15}{12}$ = 3

Step-by-step explanation:

Explanation

Given $\frac{14}{8} + \frac{15}{12}$

L.C.M 8 , 12 is 24

$\frac{14}{8} + \frac{15}{12} = \frac{14 X 3 + 15 X 2}{24}$

= $\frac{42 +30}{24} = \frac{72}{24} = 3$

Final answer:-

The value of $\frac{14}{8} + \frac{15}{12}$ = 3
