Find the rate of change between:
(1, -1)
(2,4)
Answer:
rate of change=5
Step-by-step explanation:
Hi there!
The rate of change (or the slope) is calculated from two points with the formula (y2-y1)/(x2-x1)
we are given two points: (1,-1), and (2,4)
let's label the points, to avoid confusion:
x1=1
y1=-1
x2=2
y2=4
now substitute into the formula:
*note: remember that we are subtracting the negative numbers. When it's simplified, we add the numbers.
rate of change=(4--1)/(2-1)
simplify:
rate of change=(4+1)/(2-1)
rate of change=5/1
rate of change=5

Find the slope of a line that passes through the points:
(−4, 7), (−6, −4)
Answer:
= 11/2
Step-by-step explanation:
When we have two points, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -4 -7)/(-6 - -4)
= ( -4 -7)/(-6 +4)
= -11/-2
= 11/2

Find the value of y
Answer:
y = 23
Step-by-step explanation:
The angle vertically opposite 3y is congruent, then
(5y - 4) and 3y are same- side interior angles and sum to 180°, that is
5y - 4 + 3y = 180
8y - 4 = 180 ( add 4 to both sides )
8y = 184 ( divide both sides by 8 )
y = 23

Tickets for the basketball game were sold at 4$ for adults and 2.50$ for students. If 320 tickets were sold for a total of 1100$, how many students tickets were sold? How many adult tickets were sold?
Answer: Number of students tickets were sold = 120
Number of adults tickets were sold = 200
Step-by-step explanation:
Let x= Number of adults, y = Number of students
As per given,
x+y=320 ...(i)
4x+2.5y=1100 ...(ii)
Multiply 2.5 on both the sides of (i), we get
2.5x+2.5y=800 ...(iii)
Subtract (iii) from (ii), we get
1.5x=300
[tex]x=\frac{300}{1.5}\\x=200[/tex]
From (i) y= 320-200 = 120
Hence, Number of students tickets were sold = 120
Number of adults tickets were sold = 200

Answer:
y = -x + 3
Step-by-step explanation:
Given:
Coordinates are (2, 1) and (6, -3)
y = mx + c
For Coordinate (2, 1)
1 = m(2) + c
1 = 2m + c ........... Eq1
For Coordinate (6, -3)
-3 = m(6) + c
-3 = 6m + c ........... Eq2
From Eq2 - Eq1
6m - 2m = -3 - 1
4m = - 4
m = -1
From eq 1
1 = 2m + c
1 = 2(-1) + c
1 = -2 + c
c = 2 + 1
c = 3
So,
y = mx + c
y = (-1)(x) + 3
y = -x + 3

Elijah puts $550 in an account earning 8% simple interest annually. What is the total amount of money he will have in his account after 6 years, if no withdrawals or deposits are made?
Answer:
814?
Step-by-step explanation:
Simple interest is I = PRT, so you can multiply the 550, by 1.08 by 6 to get the total.
The principal is 550, the rate is 0.08 (using 1.08 because the prior gives interest, and using a whole 1 with it will be the total), and the time is 6 years because the interest is simple annual.
use 0.08 instead of 1.08 when solving for interest.

Answer:
11/12
Step-by-step explanation:
Given the expression 1/3 + a = 5/4
Subtract 1/3 from both sides
1/3 + a - 1/3 = 5/4 - 1/3
a = 5/4 - 1/3
a = 15-4/12
a = 11/12
Hence the value of x is 11/12

Find the unknown angle measures
Options: 30°, 51.5°, 60°, 141.5°
Answer:51.5 degree
Step-by-step explanation: Since DEF is an isosceles triangle, angle D and F needs to be equal. So substract 77 from 180 and divide by 2.
Answer:
Step-by-step explanation:
let angle D and angle F be x
x+x+77=180 degree(being sum of the interior angle of a triangle)
2x=180-77
x=103/2
x=51.2 degree
both angle D and F are 51.2 degree because the base angles of an isosceles triangle are equal.
