Explanation:
He starts off with 200 cards. Then he adds on 25w more cards for each week (w). Overall, he'll have 200+25w cards
We can think of it like this:
After 1 week, he adds on 25*1 = 25 cardsAfter 2 weeks, he adds on 25*2 = 50 cards totalAfter 3 weeks, he adds on 25*3 = 75 cards totalAfter 4 weeks, he adds on 25*4 = 100 cards total, and so on.After w weeks, he adds on 25w cards totalSo that's another way to see where the 25w comes from.
The expression 200+25w is the same as 25w+200. This is because we can add two numbers in any order.
------------
Since he wants to know when he'll have more than 750 cards, this means we set 25w+200 greater than 750.
That's how we get to the answer of 25w+200 > 750
Notice how there isn't a line under the inequality sign. We aren't using the "greater than or equal to" symbol here. We want to know when the cards gets over 750, but we don't want to know when it's equal to 750.

Write the slope-intercept form of a linear equation given the slope and y-intercept.
Slope : -4/3
y-intercept: -3
Answers
Answer:
y= mx+c (m-slope, c- y intercept)
y= (-4/3) x - 3
or, y= (-4x-9)/3
or, 3y = -4x -9 (you can leave it here)
or, 4x +3y=-9
or, 4x+3y+9 = 0
the last three equations are all valid answers.

Answers
Given:
The equation is:
[tex]x^2-64=0[/tex]
One solutions is 8.
To find:
The other solution of the given equation.
Solution:
We have,
[tex]x^2-64=0[/tex]
It can be written as:
[tex]x^2-8^2=0[/tex]
[tex](x-8)(x+8)=0[/tex] [tex][\because a^2-b^2=(a-b)(a+b)][/tex]
Using zero product property, we get
[tex]x-8=0[/tex] and [tex]x+8=0[/tex]
[tex]x=8[/tex] and [tex]x=-8[/tex]
It is given that the one solutions is 8.
Therefore, the other solution is -8.

What is the length of the hypotenuse of the triangle?
7 ft
4 ft
Answers
Answer:
√65 ft = 8.1 ft
Step-by-step explanation:
We solve using Pythagoras Theorem
c² = a² + b²
c = √a² + b²
Where c = Length of the Hypotenuse
a = 4ft , b = 7ft
Hence
c = √4² + 7²
c = √16 + 49
c = √(65)
c = 8.0622577483 ft
Approximately = 8.1 ft
Therefore, the length of the hypotenuse is √65 ft = 8.1 ft

Answer:
perimeter of rectangle = 102.4 cm
Step-by-step explanation:
here's your solution
==> perimeter of rectangle = 2(length + width)
=> length = 40.3 cm
=> width = 10.9 cm
=> perimeter = 2(40.3 + 10.9)
=> perimeter = 2(51.2)
==> perimeter of rectangle = 102.4 cm

Arthur, Kyle, and Tom are all on the baseball team. At the end of the season, they compared how many home runs each of them hit. Arthur noticed that if he doubled the number of home runs he hit and then subtracted 1, he would get the number of home runs Kyle hit. Tom noticed that if he subtracted 1 from the number of home runs he hit and then doubled that number, he would get the number of home runs Kyle hit. Write an expression representing the number of home runs Kyle hit in terms of the number of home runs Arthur hit, a. Enter your response in the first response box. Write an expression representing the number of home runs Kyle hit in terms of the number of home runs Tom hit, t.
Answers
Answer:
k = 2a - 1
k = 2(t - 1)
Step-by-step explanation:
Let :
Number of home runs Arthur hit = a
Number of home runs Kyle hit = k
Number of home runs Tom hit = t
Kyle's home runs, k in terms of Arthur's home run : Double the value of a ; then subtract 1
k = 2a - 1
Kyle's home runs in terms of Tom's home runs ;
Subtract 1 from t `
k = 2(t - 1)
