Answer:
D. y + 5 = 9/2(x + 7); –9x + 2y = 53
Step-by-step explanation:
The equation:
y - y 1 = ( y2 - y1 ) / ( x2- x1) * ( x - x1 )
y - ( - 5 ) = ( 4 + 5 ) / ( - 5 + 7 ) * ( x - ( - 7 ) )
y + 5 = 9/2 ( x + 7 )
y + 5 = 9/2 x + 63 /2 / * 2
2 y + 10 = 9 x + 63
- 9 x + 2 x = 53
Answer:
C ) y + 5 = 9/2 ( x + 7 ) ; - 9 x + 2 y = 53
Option C is correct
Step-by-step explanation:
Point slope form:
The equation of line is given by:
....[1] where m is the slope and a point lies on the line.
Given that:
A line passes through (-7,-5) and (-5,4).
Calculate slope:
Slope is given by:
Substitute the given values we have;
Simplify:
Substitute thee value of m and (-7, -5) in [1] we have;
Simplify:
⇒
Using distributive property :
Subtract 9x from both sides we have;
Subtract 10 from both sides we have;
Therefore, an equation for the line in point-slope form is and the equation in standard form using integers is
Phân tích : x^3+2x^2y+xy^2-9x
Answer:
x(x+y+3)(x+y-3)
Step-by-step explanation:
x³+2x²y+xy²-9x
= x((x²+2xy+y²)-3²)
= x((x+y)² - 3²)
= x(x+y+3)(x+y-3)
Two barrels, that are each cylinders with a radius of 2 feet, are filled with juice. The smaller barrel has a height of 3 feet. The larger barrel has a height of 5 feet. The total volume of the barrels is 100.48 cubic feet
a. What is the volume of the larger barrel?
b. Explain how you can find the volume of the smaller barrel?
step by step solution please thank you
Step-by-step explanation:
a. the volume of the larger barrel =
π.r².h = 3.14 × 2² × 5
= 3.14 × 20
= 62.8 cu. ft
b. the volume of the smaller barrel =
3.14 × 2² × 3
= 3.14 × 12
= 37.68 cu. ft
or it can find the volume by using
the subsraction :
100.48 - 62.8 = 37.68 cu. ft

Brent earns $10 for every car he washes and $15 for every lawn he mows. Let x represent the number of cars he washes and y stand for every lawn he mows.
Which expression represents the total money Brent will earn washing cars and mowing lawns?
15x+10y15 x plus 10 y
15y+10x15 y plus 10 x
15+10(xy)15 plus 10 times x y
10+15(xy)
ill be happy if i get a proper answer thank you
Answer:
The expression that represents the total money Brent will earn is the second option or 15y + 10x because y is the number of lawns he mows and he earns $15 for every lawn he mows and x is the number of cars he washes and he earns $10 for that.

which of the following graphs is the solution set of 1/2x + 7 >3
Answer:
x>−8
Step-by-step explanation:
Step 1: Subtract 7 from both sides.
1/2 x 7+7-7>3-7
1/2 x>-4
Step 2: Multiply both sides by 2.

Answer:
Step-by-step explanation:
Let the number be x
Eight less than a number: x - 8
Product of six and (x - 8) : 6*(x-8)
10 less than 6(x -8) : 6*(x-8) - 10

Answer:
f(5) is greater and it is 1.7778 times greater than g(5)
Step-by-step explanation:
f(5) = 3(5)^2 +5
f(5) = 3(25) + 5
f(5) = 75 + 5
f(5) = 80
g(5) = 11(5) - 10
g(5) = 55 - 10
g(5) = 45

Two fractions can be easily added together when they
have a common denominator.
a. What is one denominator you could use to add the
following two fractions?
3 1
-+
8 12
Answer:
One denominator you could use to add the two fractions 3/1 and 8/12 is 12.
Step-by-step explanation:
When adding the fractions 3/1 and 8/12, the first step is to multiply both the numerator and denominator by the same number until you end up with common denominators. Here, the best thing to do is multiply both 3 and 1 by 12 which ends in 36/12; from that point on, you just do the simple math of 36/12 + 8/12.

Write the following
biconditional as two conditional statements:
Two angles are complementary if and only if the sum of their measures is 90.
Step-by-step explanation:
two angles that equal 90 degrees are complemterary
two complementerary angles equal 90 degrees
Two supplementary angles differ by 44 degrees. Find the angles
Answer:
hope it helps and u understand
check the steps in picture attached
Two supplementary angles equal 180 degrees:
Subtract the difference:
180-44 = 136
Divide that by 2:
136/2 = 68
One angle is 68 degrees
The other angle is 68 + 44 = 112 degrees
find <ABC =2x and <CBD=3x-10
Answer:
x = 20
Step-by-step explanation:
m<ABC and m<CBA are complementary angles which means their sum is 90 degrees:
2x + 3x - 10 = 90 add like terms
5x - 10 = 90 add 10 to both sides
5x = 100 divide both sides by 5
x = 20 to find the angles replace x with 20
m<ABC = 40 and
m<CBA = 50
