Answer:
1/17
Step-by-step explanation:
You're on the right track so far!
(2³ + 3²) ⁻¹
= (8 + 9) ⁻¹
= (17) ⁻¹
= 1/17 (Remember, (a)⁻ⁿ = 1 / aⁿ)
The equation in slope-intercept form is y = 13/8x -17/8 and the equation in standard form is 13x -8y = 17
<h3>Equation of a line</h3>
A line is the shortest distance between two points. The equation of a line in slope-intercept form is y = mx + b while as a standard notation is Ax+By = C
Given the coordinate points (-3, -7) and (5, 6)
<u>Determine the slope</u>
Slope = 6-(-7)/5-(-3)
Slope = 13/8
<u>For the y-intercept</u>
6 = 13/8(5) + b
6 = 65/8 + b
b = 6 - 65/8
b = -17/8
The equation in slope-intercept form is y = 13/8x -17/8
Write in standard form
Recall y = 13/8x - 17/8
<em>Multiply through by 8</em>
8y = 13x - 17
-13x + 8y = -17
13x -8y = 17
Hence the equation in standard form is 13x -8y = 17

Answer:
There are <u>35 boys</u> in the class.
Step-by-step explanation:
Girls to Boys ratio = 3:7
Total number of students in class = 50
Let total number of girls be '3x' and total number of boys be '7x'
Total number of girls + Total number of boys = Total number of students
3x + 7x = 50
10x = 50
x = 50/10
x = 5
Total number of girls = 3 × 5 = 15
Total number of boys = 7 × 5 = 35
Answer:
Too much please's
Step-by-step explanation:
Please stop begging people to help.
Answer: Mary covers less distance for 320 m
Step-by-step explanation:
Psqere=4a
Prect=2(a+b)
anna=4*4a (a=90m)
Anna=16*90=1440m
Mary=4*2(a+b)=8(a+b)=8*(80+60)=8*140=1120 m
anna-Mary=1440-1120=320m
