Answer:

<em>Value</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>expression</em><em> </em><em>is</em><em> </em><em> </em><em>-35</em>

Step-by-step explanation:

Given \: expression \: is \\ {a}^{2}  - 2ac + 5c \\ values \: are \: a =  - 3 \:  \ \:  \:  \:  b = 2 \:  \:  \:  \: c =  - 4 \\ on \: substituting \: the \: values \ \\ in \: the \: given \: expression \\  { - 3}^{2}  - 2( - 3)( - 4) + 5( - 4) \\  = 9 - 24 - 20 \\    =  - 35

The measure of a supplement of an angle is 40 more than two times the measure of the complement of the angle. find the measure o
saul85 [17]
 2 angle A and B are Complementary means that the sum of their measures is 90°. 

 2 angle A and B are Supplementary means that the sum of their measures is 180°. 


Thus, if the measure of angle A is x:

the measure of the supplement is 180°-x
the measure of the complement is 90°-x


"The measure of a supplement of an angle is 40 more than two times the measure of the complement of the angle. "

let the measure of the angle be x, then we have:

180°-x=40°+2(90°-x)

180°-x=40°+180°-2x

2x-x=40°

x=40°


Answer: 40°

What is the intersection of y=7 and y=1\2x+6
kotegsom [21]
Y=7 is just a straight horizonal line that is perpendicular to the y axis at 7

and y=1/2x+6, is in y=mx+b form where m=slope and b=yintercept so

to find the intersection, yo just find when both sentances are correct so

y=7
subsitute that into y=1/2x+6

7=1/2x+6
subtract 6 from both sides
1=1/2x
multiply both sides by 2
2=x

so the point (2,7) is the intersection

As a membership fee a health club charges a one time amount of $40 and charges $25 for each month. The total fee after m months
ICE Princess25 [194]
First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months.
To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x.
240 = 25x + 40
subtract 40 from each side
200= 25x
divide by 25
8 = x
8 months

Zielflug [23.3K]

Answer: 68887

Step-by-step explanation: the geometics series is (the previous number in the series) x 3, so 63 x 3 =189 x 3 =567 x 3 = 1701 x 3 = 5103 x 3 =15309 x 3 = 45927 and you add all those numbers up to get 68887

Solve 5n – 7p + 3n = 25p for n.
saul85 [17]

5n – 7p + 3n = 25p

Combine like terms

8n - 7p = 25p

Add (7p) to both sides

8n - 7p + 7p = 25p + 7p

Simplifying

8n = 32p

Divide both sides by 8

8n / 8 = 32p / 8

Simplifying

n = 4p
