Question 7. y = -2x + 7. y = mx + b; m= slope (-2) (3, 1) resolve for y. you have : 1= -2 (3) + b; 1 = -6 + b; 1 + 6 = b; b = 7.
Answer:
Perimeter of the rectangle = 6 x +20
Perimeter of the rectangle = 0<em> x² + 6 x + 20</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the length of the rectangle = 2x +3
Given that the width of the rectangle = x +7
Perimeter of the rectangle = 2(length + width)
<u>Step(ii):-</u>
Perimeter of the rectangle = 2(length + width)
= 2(2 x +3 + x+7)
= 4x +6+2x+14
= 6 x +20
<u><em>Final answer:-</em></u>
Perimeter of the rectangle = 6 x +20
Perimeter of the rectangle = o x² + 6 x + 20
Answer:
The algebraic expression of "two more than the quotient of six and a number, n is 2 + 6/n
Step-by-step explanation:
The quotient number of six and a number n = 6 / n
two more than the quotient of six and a number, n = 2 + 6/n
The algebraic expression of "two more than the quotient of six and a number, n is 2 + 6/n
Answer:
C, D
Step-by-step explanation:
Step 1: (3^2)^3 * 3^6 / 3^4
Step 2: (9)^3 * 3^6 / 3^4
Step 3: 729 * 3^6 / 3^4
Step 5: 729 * 729 / 3^4
Step 6: 531441 / 3^4
Step 7: 531441 / 81
Step 8: <u><em>6561</em></u>
A = 27
B = 2187
<u><em>C = 6561</em></u>
<u><em>D = 6561</em></u>
E = 2187
Answer:
d
Step-by-step explanation:
1.75 ( would be the coffee) + 1.50d (donuts each but an unknown quantity)
total amount must be less than $37 dollars
Your answer would be 37.00 - 1.75 = 35.25 cents
35.25 / 1.50 = 23.5 donuts - you can not purchase a half of a donut so you can buy 1 coffee and 23 donuts for $36.25
