Answer:
#1 - First option: y + 7 = [tex]\frac{-1}{4}[/tex](x -4)
#2 - First option: y = 2x - 5
Step-by-step explanation:
#1
Given: (x1,y1) = (4,-7) and m = [tex]\frac{-1}{4}[/tex];
To find the point slope form which is
y - y1 = m(x - x1); substitute (x1,y1) and m
y - (-7) = [tex]\frac{-1}{4}[/tex](x -4)
y + 7 = [tex]\frac{-1}{4}[/tex](x -4)
#2
Given: points (x1,y1) = (0, -5) and (x2,y2)=(4,3)
To find the slope we use
m = [tex]\frac{(y2-y1)}{(x2-x1)}[/tex] = [tex]\frac{(3-(-5))}{(4-0)}[/tex] = [tex]\frac{8}{4}[/tex] = 2
Now pick a number to find b
y = mx + b
y1 = mx1 + b
-5 = 2(0) + b
b = -5
now plug into y = mx + b; which is
y = 2x - 5

∠ EDF =104°
Step-by-step explanation:
The measure of the chord- chord angle EDF is half the sum of the of the arcs intercepted by the angle and its vertical angle, that is
∠ EDF = [tex]\frac{1}{2}[/tex] (arc EF + arc GU )
= [tex]\frac{1}{2}[/tex] (147 + 61)°
= [tex]\frac{1}{2}[/tex] × 208°
= 104°
The sum of two numbers is 116 and their difference is 18. Find the larger number.
Answers
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Answer:
67
Step-by-step explanation:
let larger number be x and the other be y.
x - y = 18
x = 18+y
now, x + y = 116
therefore, 18+y+y= 116
18 + 2y =116
2y = 116-18
2y = 98
y = 98/2 = 49
larger number = 49 + 18 = 67

Earl runs 60 meters in 40 seconds. How many meters does Earl run per second?
Earl runs ___ meters per second.
Answers
Answer:
Earl runs 1.5 meters per second
Step-by-step explanation: 60 divided by 40= 1.5
Answer:
1.5 meters/s
Step-by-step explanation:
Since he runs 60 meters in 40 seconds, we can divide 60 by 40 to get how quickly he runs in meters/s. 60/40 = 6/4 = 3/2 = 1.5, so Earl runs 1.5 meters per second.

Find the constant of proportionality for the table and write in the form y = kx.
A) y = 1/6x
B) y = 6x
C) y = 7x
D) y = 42x
Answers
Answer:
The constant of proportionality for the table will be: k=6
Thus, the equation becomes
[tex]y=kx[/tex]
[tex]y=6x[/tex]Step-by-step explanation:
The constant of proportionality, k, is the constant value of the ratio of two proportional quantities y and x.
We know the equation
[tex]y=kx[/tex]
where k is the constant of proportionality.
Looking at the graph,
at x=7, the value of y=42
so the ratio of y/x = 42/7 = 6
at x=14, the value of y=84
so the ratio of y/x = 84/14 = 6
at x=21, the value of y=126
so the ratio of y/x = 126/21 = 6
at x=28, the value of y=168
so the ratio of y/x = 168/28 = 6
We observe that the ratio of y/x remains constant which y/x=6
so using the equation
[tex]y=kx[/tex]
take any point let say (7, 42)
42 = k(7)
42/7=k
6 = k
Therefore, the constant of proportionality for the table will be: k=6
Thus, the equation becomes
[tex]y=kx[/tex]
[tex]y=6x[/tex]

Answers
Answer:
A, B and D
Step-by-step explanation:
The zeros of f(x) are the points located on the x- axis, that is where y = 0
We can check which ones are the solutions by finding the zeros of f(x)
To find the zeros let f(x) = 0 , that is
(x² + 2x - 8)(x - 6) = 0 ← factorise the quadratic
(x + 4)(x - 2)(x - 6) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 2 = 0 ⇒ x = 2
x - 6 = 0 ⇒ x = 6
There are 3 zeros at x = - 4, x = 2, x = 6
These are located at A, B and D
Answer:
A, D, B
Step-by-step explanation:
The roots (zeroes) are the x values where the graph intersects the x-axis. To find the roots(zeroes), replace y with 0 and solve for x.

There are several bowls containing various amounts of grapes on a table. When 12 of the bowls each had 8 more grapes added to them, the mean (average) number of grapes per bowl increased by 6. How many bowls of grapes are on the table?
Answers
Answer:
There are 16 bowls
Step-by-step explanation:
Number of bowls = x
Total grapes added = 12 x 8 = 96
The average increased by 6
So 96/6 = 16
There were 16 bowls of grapes on the table
OR
12 x 8 = 96
96/6=16
Answer:
16 bowls
Step-by-step explanation:
Number of bowls = x
Total grapes added = 12 x 8 = 96
The average increased by 6
So 96/6 = 16
There were 16 bowls of grapes on the table

What is the average rate of change in profit from Hour 5 to Hour 10?
Answers
Answer:
d
Step-by-step explanation:
so at 5 hours he was at a profit of 900 and 5 hours later he is at a profit 1500 then you can sub tract 900 from 1500 which gives you 600
$600 is the average rate of change in profit from Hour 5 to Hour 10
What is Rate of change?A rate of change is a rate that describes how one quantity changes in relation to another quantity
The given table is
Hour Profit
0 $0
2.5 $500
5 $900
7.5 $1200
10 $1500
5 hours the profit is 900 and 5 hours later he is at a profit 1500
We need to subtract 900 from 1500 to find the average rate of change.
1500-900=600
Hence $600 is the average rate of change in profit from Hour 5 to Hour 10
