Byron’s workout starts with a
warmup at home, and then he runs
at 4 mi/h. After half an hour of
running, he is 2 miles from home.
What is an equation in point-slope form that represents Byron’s
distance from home, y, after
x hours?
Answer:
An equation in point-slope form that represents Byron’s distance from home, y, after x hours is y=4x+2
Step-by-step explanation:
Speed of Byron = 4 miles / hour
Distance traveled in x hours = [tex]Speed \times time[/tex]
Distance traveled in x hours = 4x
We are given that After half an hour of running, he is 2 miles from home
So, Total distance = 4x+2
So, y = 4x+2
Hence an equation in point-slope form that represents Byron’s distance from home, y, after x hours is y=4x+2
Ross says a $154.95 skateboard at 40% off is cheaper than a $250.95 skateboard at 60% off. Is he correct? How much cheaper is the offer?

Step-by-step explanation:
y is equal to the modulus of x-2 two because in the graph the the line cut at -2
Find the zeros of the function algebraically.
f(x) = 16x4 − 49x2
Answer: Plz mark me brainlest
Step-by-step explanation:
Just Simply Use Identity:
a^2 - b^2 = ( a+b) ( a-b)
Then:
( 49X^4 - 36 X^2) = 0
(7 X^2 + 6 X) ( 7X^2 - 6X) =0
7X^2 + 6X = 0, then X( 7X +6) =0 X=0, 7x +6 =0 X = -6/7
7X^2 -6x =0 X( 7x - 6) =0 X =0 7x -6 =0 X =6/7
Pull out a factor of x² from f(x) :
16x⁴ - 49x² = x² (16x² - 49)
Now write it as a difference of squares, then factorize:
16x⁴ - 49x² = x² ((4x)² - 7²)
16x⁴ - 49x² = x² (4x - 7) (4x + 7)
Set this equal to 0 and solve for x :
x² (4x - 7) (4x + 7) = 0
x² = 0 or 4x - 7 = 0 or 4x + 7 = 0
x = 0 or x = 7/4 or x = -7/4
What is the value of x?
Answer:
10
Step-by-step explanation:
5x - 17 = 3x + 3 (vertically opposite angles)
5x - 3x = 3 + 17
2x = 20
x = 20/2
x = 10

Answer:
[tex]x = 110 \\ (exterio \: angles \: of \: a \: traingle \: sum \: up \: to \: 360)[/tex]
Answer:
x = 110
Step-by-step explanation:
Assuming you require the value of x
The sum of the external angles of a triangle = 360°
The 3 angles shown are external angles.
Subtract the sum of the 2 given angles from 360 for x
x = 360 - (140 + 110) = 360 - 250 = 110

a boat traveled 27 miles in 2 hours. at this rate, how many miles will the boat travel in 1/2 an hour
Answer: 9
Step-by-step explanation:
HELLPPPPPP -9(x +3) =27
-9x + (?) =27 WILL GET BRAINLYIST
Answer:
-27
Step-by-step explanation:
Given expression:
-9(x + 3) = 27
Now use the open the bracket;
-9x - 27 = 27
Given -9x + (?) = 27
Comparing the two equations shows that the question mark corresponds to the value -27;
The solution is -27

help with this !!! thanks
Answer: Casey bought 4 1/2 pounds of apples
The equation is 0.88x - $1.50 = 2.46
x is the unknown number of pounds of apples.
0.88 is the cost per pound, 0.88x is the total cost of the apples before the discount .The discount is $1.50 $2.46 is the cost after the discount.
Part b Step-by-step explanation:
0.88x - $1.50 = 2.46 . Add $1.50 to both sides
0.88x - $1.50 + $1.50 = 2.46 + 1.50
On left, 1.50-1.50=0 so "cancels' on the right, add $2.46 + 1.50 = 3.96
0.88x = 3.96 is the cost before discount . Divide both sides by .88
.88x/.88 = 3.96/.88 . .88/.88 = 1 so 1 'cancels' leaving x. 3.96/.88 = 4.5
x = 4.5
part c
4.5 is 4 1/2, the (previously unknown) number of pounds of apples.
Casey bought 4 1/2 pounds of apples.

help ill give hella points plz thx
Answer:
Using the variables it gives us it is B=150m
Step-by-step explanation:
1.) $1800-$1350=$450
$1350 is the total balance after 3 months and $450 is the amount he has payed in those 3 months
2.) 450/3=150
You do 450/3 to find how much he is paying per month. If you want to check your work do 1800-1050=750 then do 750/5=150
So you put the numbers in B = Zachary's balance after m months and you get B=150m
Answer:
150m

The perimeter of a rectangle is 64 inches. Find the value of x if the width is 22 inches and tenth is 2x inches.
Answer:
5
Step-by-step explanation:
Did you mean length instead of tenth? If so, 22*2=44, 64-44=20, 20/2=10. The length of the rectangle is 10 so to find the value of x, divide 10 by 2 so, 10/2=5, and x is equal to 5. : )
