The point-slope form of the equation of the line that passes through f 5, -1) and to, -7 is y +7(x-10. What is thestandard form of the equation for this line?O 2x -5y15O 2x-5y --172x 5y -152x 5y -17
Answers
Answer C : 2x+5y=-15
Indeed:
y+7=-2/5(x-10)
==>y+7=(-2x/5+20)/5
==>5(y+7)=-2x+20
==>5y+35=-2x+20
==>2x+5y=20-35
==>2x+5y=-15

-Can you write an equation that relates quarts of blood to weight?
-How can you use the equation to determine solution?
Answers
Step-by-step explanation:
Given that amount of blood is directly linked to body weight of the person.
b = Amount of blood
W = weight of the person
k = proportionality constant or constant of variation
1) Given that, person who weighs 160 lb has about 4.6 quart of blood.
b = 4.6 quart, W = 160 lb
The constant of variation is of value 0.02875 quart/lb.
2) An equation that relates quarts of blood to weight:
3) If, b = ?,W = 175 lb
5.03125 quarts of blood are in the body of a 175-lb person.
w ∝ b
where w = body's weight, b = amount of blood
Changing it into a direct variation becomes
w = kb or k = w/b
where k = proportionality constant
We know that k is obviously constant, we equation it into two states as
w₁/b₁ = w₂/b₂
Given that w₁ = 160 lb, b₁ = 4.6 qt, b₂ = 175, w₂ = 175 lb. Then b₂ will be
160/4.6 = 175/b₂
b₂ = 160/(4.6*175) = 160/805 = 0.20 quarts

Answer:
C. $56,900
Step-by-step explanation:
Given the equation of the Social Security (FICA) wage base y, (in thousands of dollars) from 1983 to 1988 expressed as y=1.9x+34.1
for us to calculate his wage base in 1995, we need to calculate the total number of years between 1983 to 1995 i.e 12 years
Substitute x = 12 into the expression above as shown;
y=1.9x+34.1
y = 1.9(12)+ 34.1
y = 22.8 + 34.1
y = 56.9
Since y is in thousand of dollars then
y = 56.9 * 1000
y = 56900
y = $56,900
Hence FICA wage base in 1995 is $56,900
