Answer:
7=7
Step-by-step explanation:
Simplify
7+37+3 to 1010.
7x=107x=10
Divide both sides by:
77 x={10}{7}x= 7 10
Let x=10/7x= 7 10/7 -3=77× 7 10
−3=7
Cancel 7:
10-3=710−3=7
Simplify
10-310−3 to 77.

(1) The first velocity of the car with two washers at the 0.25 meter mark is 0.125 m/s.
(2) The second velocity of the car with two washers at the 0.5 meter mark is 0.25 m/s.
What is velocity?Velocity is the rate of change of displacement with time. The velocity of the cars depends on displacement and time of motion.
First velocity of the car at the 0.25 meter markThe first velocity is calculated as follows;
v1 = 0.25 m / t1
let t₁ = 2 s
v₁ = 0.25/2
v₁ = 0.125 m/s
Second velocity of the car at the 0.5 meter markv2 = 0.25 m / (t2 – t1)
let t₂ = 3 s
v₂ = 0.25(3 - 2)
v₂ = 0.25 m/s
The complete question is below:
Calculate the first and second velocities of the car with two washers attached to the pulley, using the formulas

Bob's monthly net income is $3,000. Bob pays $950 for rent, $250 for all
utilities, and $1,850 in other fixed and variable expenses. What is Bob's
cash flow?
A.Negative cash flow, $50
B.Negative cash flow, $3,050
C.ositive cash flow, $3,050
D.Positive cash flow, $50
Answer:
A: Negative cash flow, $50
Step-by-step explanation:
Bob makes $3000 a month.
Every month he has to pay $950:
3000 - 950 = 2050
Pay an additional $250:
2050 - 250 = 1800
And another additional $1850:
1800 - 1850 = -50
Therefore, he has a negative cash flow of $50 a month.

A group of biologists found a total of 28 loggerhead turtle nests along a beach during a certain season. This was 40% of the total number of turtle nests the group found during that season. What was the total number of turtle nests the group found during that season?
70
85
110
143
Answer:
A
Step-by-step explanation:
Let T represent the total number of turtle nests found during the season.
The 28 turtle nests was 40% of 0.4 of the total. Therefore:
[tex]28=0.4T[/tex]
So, to find T, divide both sides by 0.4:
[tex]T=70[/tex]
So, the total number of turtle nests the group found during tthe season was 70.
Hence, our answer is A.

Answer:
y = -2x + 17
Step-by-step explanation:
The line is parallel to 4x + 2y = 10, and parallel lines have the same slope. Let's convert this line into slope intercept form:
2y = 10 - 4x,
y = -2x + 5
So the slope of this line and our line [the line which we want to determine in slope intercept form] is -2
Given the point (7, 3) and slope -2 we can solve for the y-intercept;
y = mx + b,
3 = -2(7) + b,
-14 + b = 3,
b = 17
Your solution is y = -2x + 17 (First option)

Please anyone help me 38 points
Answer:
An equation for the parabola would be y²=-19x.
Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis. This means we will use the standard form
(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.
Beginning with the directrix:
x=h-p=4.75
h-p=4.75
Since the vertex is at (0, 0), this means h=0 and k=0:
0-p=4.75
-p=4.75
p=-4.75
Substituting this into the standard form as well as our values for h and k we have:
(y-0)²=4(-4.75)(x-0)
y²=-19x
