Answer:
x ≥ 8
Step-by-step explanation:
Let x be the number of pounds he buys. As each pound costs 7 dollars and he must spend at least 56 dollars, we have:
7x ≥ 56
x ≥ 8 (divide each side by 7)
Thus, our answer is any number above 8.
state is a given functions are inverses. NO LINKS!! Part 2
Step-by-step explanation:
5.
g(x)=-2x+1
let y=2x+1
Interchanging role of x & y
x=2y+1
y=½x-½
g-¹(x)=½(x-1)
not
equal to f(x)=-x+1
Given function are not function of each other .
6.
g(x)=-x
let
y=-x
Interchanging role of x & y
x=-y
y=-x
g-¹(x)=-x
not
equal to f(x)=3+⅓x
Given function are not function of each other .

Answer:
none of the function pairs are inverses
Step-by-step explanation:
Inverse linear functions will meet all of several requirements:
each is a reflection of the other about the line y=xthe solution of the simultaneous equations in on the line y=xin standard form, the coefficients are swapped (only)the product of the slopes is 1_____
For these problems, it is probably easiest to look at the last requirement. Each function is given in slope-intercept form, so the slope is simply the x-coefficient.
5) The product of slopes is (-2)(-1) = 2 ≠ 1 . . . NOT inverses
6) The product of slopes is (-1)(1/3) = -1/3 ≠ 1 . . . NOT inverses
7) The product of slopes is (-4/3)(-1/2) = 2/3 ≠ 1 . . . NOT inverses
8) The product of slopes is (3/2)(-5/2) = -15/4 ≠ 1 . . . NOT inverses

Nicholas is adding by place value from right to left. When he adds the hundredths, he gets 0.46. Describe what his next step should be. NO LINKS!!!!
9514 1404 393
Answer:
record 6 hundredths; add 4 to the numbers of tenths
Step-by-step explanation:
Nicholas needs to write down the 6 and "carry" the 4, adding it to the numbers of tenths.
Depending on the method you've been taught, the 4 may be written above the column with place value of tenths, or it may be written on a separate sum line.

Which box plot has the greater IQR? Explain.
Ms.A thinks that the 25% of the NY Knicks are at least 74 inches tall. Do you agree or disagree?
Explain using mathematical reasoning.
Ms.T rann thinks that 1the NY Knicks has a larger spread than Liverpool. Do you agree or disagree? Explain using mathematical reasoning.
Answer:
1. the team of Liverpool FC has the shortest player because the minimum is 64.
2. ny Knicks has the tallest player with a height of 84.
3. the NY Knicks box has the largest IQR because 82 - 74 = 8.
MS. A is wrong bc the 75% of players are taller than 74 inches.

I need to find the value of x help needed
Answer:
x=33°
Step-by-step explanation:
Hi there!
We're given a triangle, with 2 known measures of angles in the triangle
54° and 93°
the other (unknown) value is x
the angles in a triangle add up to 180°
therefore, to find the value of x, we can add up the values of the 3 angles and set that to equal 180
54°+93°+x°=180°
add 54 and 93
147°+x°=180°
subtract 147 from both sides
x=33°
so the value of x is 33 degrees
Hope this helps!
Which of the following equations is a solution for 5745?

D.NXS = 45
Answer:

Step-by-step explanation:
If the line through (-2,4)and ) 5,D)is parallel to the graph of y= 3X +4 find the value of d
Answer:
D = 25
Step-by-step explanation:
For 2 lines to be parallel, they must have the same sloe;
Given the coordinates (-2,4)and (5,D)
Slope = D-4/5-(-2)
Slope = D-4/5+2
Slope = D-4/7
Given the equation y = 3x + 4, comparing to y = mx+b
mx = 3x
m = 3
Hence the slope is 3
Equating the slopes
D-4/7 = 3
D-4 = 3*7
D-4 = 21
D = 21+4
D = 25
Hence the value of D is 25
Plz help me well mark brainliest if correct!....
Answer:
C
Step-by-step explanation:
B can immediately be eliminated because it has an area of 14.
A and C have an area of 10.
So add the sides.
C:
4 + 4 + 1 + 1 + 2 + 2 + 1 + 3
= 18
A: 3 + 3 + 2 + 2 + 1 + 1 + 1 + 1 =

I don’t get how they added to get the amount of money earned, I need help if you can explain how I can find the amount of money earned for 40 hours.
Answer:
its 34
Step-by-step explanation:
you just add
Answer:
330
Step-by-step explanation:
123.75 : 15= 8,25--> the money you earn in one hour.
8,25 x 10= 82,50--> the money you earn in 10 hours.
247,50 (30h) + 82,50 (10h)= 330 (40h)

Principal, $3000; Annual interest rate, 5.4%; time, 5 years
Answer:
SI = $810
Amount = $3,810
Step-by-step explanation:
Given that ,
P = $ 3,000 R = 5.4% T = 5 yrs .We can use the formula of SI to find the interest as ,
=> SI = P × R × T / 100
=> SI = $ 3000 × 5.4 × 5 / 100
=> SI = $ 30 × 5.4 × 5
=> SI = $ 810 .
If you want to know total amount , then ,=> Amount = SI + P
=> Amount = $ 810 + $ 3,000
=> Amount = $ 3,810
Hence the Amount is $3,810 and the SI is $810 .Answer:
Step-by-step explanation:
3000*(.054)(5)= $810
