Answer:
m < 49/12
Step-by-step explanation:
The portion of the quadratic formula under the square root sign is the discriminant.
If the discriminant is > 0 then there are two real roots.
b² -4ac > 0
-----------------------------
7² - 4(3)m > 0
49 - 12m > 0
Subtract 49 from both sides
-12m > -49
Divide both sides by -12
(when multiplying or dividing by a negative the inequality must be reversed)
m < 49/12

WHATS THE ANSWER
Answer:
Step-by-step explanation:
Parallelogram A B C D is shown. The length of A B is 4 y minus 2, the length of B C is 2 x + 2, the length of D C is 2 y + 6, and the length of A D is 3 x minus 1.
What is the perimeter of ABCD?
14 units
38 units
44 units
49 units
Step-by-step explanation:
Correct option is
A
x= 4 and y = 5
Let the parallelogram be ABCD Perimeter= 40cm
AB =3x cm BC=2x cm(given)
Perimeter of parallelogram 2(3x+2x)=40
solving equation we get x=4
Also,AB=CD(opposite sides of parallelogram) 3x=2(y+1) (given)
Putting x=4
3(4)=2y+2
12=2y+2
10=2y
Hence y=5 and x=4

Each gridline represents one mile. If Ryan drove from home to the soccer field and then from the soccer field to the library, traveling in a straight line to each destination, he would have traveled ___ miles by the time he reached the library.
Answer:
13units
Step-by-step explanation:
Using the distance formula;
D = √(x2-x1)²+(y2-y1)²
Distance from home to the soccer field is expressed as;
Home (0,0) and soccer field (-4,3)
D =√(3-0)²+(-4-0)²
D =√3²+4²
D =√9+16
D = √25
D = 5
Distance from soccer field to library is expressed as;
Library (4,3) and soccer field (-4,3)
D =√(-4-4)²+(3-3)²
D =√(-8)²+0²
D =√64
D = 8
Hence the total distance = 5 + 8 = 13units

If 2(x-y)=3y, what is the ratio x/y
Answer:
1 : 2.5
Step-by-step explanation:
Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).
2(x-y)=3y
divide both sides of the equation by 2
x - y = 3y/2
x - y = 1.5y
combine like terms together
x = 1.5y + y
x = 2.5y
ratio of x : y
1 : 2.5

Answer:
shaded/square = (50π cm²)/(400 cm²) = π/8
Step-by-step explanation:
The quarter circle has area ...
A = (1/4)(πr²) = π/4(20 cm)² = 100π cm²
The half-circle has area ...
A = (1/2)(πr²) = π/2(10 cm)² = 50π cm²
Then the area of the shaded portion is ...
shaded = 100π cm² -50π cm² = 50π cm²
__
The area of the square is ...
A = s² = (20 cm)² = 400 cm²
Then the ratio of interest is ...
shaded/square = (50π cm²)/(400 cm²) = π/8
Now you try it..

Mark went to the hobby shop and bought 2 lego sets at $38.95 each and some remote car. If he
spent a total of $121.85, what was the cost of the remote car?
Answer:
43.95
Step-by-step explanation:
38.95*2 = 77.9
77.9 + x = 121.85
x = 121.85 - 77.9
x = 43.95
Write the word sentence as an inequality.
Then solve the inequality.
Five more than a number x is less than 17.
An inequality that represents this word sentence is x+5<17
The solution is ?
Answer:
x≤11
Step-by-step explanation:
x+5<17, I can subtract 5 on both sides so
x+5<17
-5 -5
x<12
that's wrong though because my x needs to make my answer less than x to make the statement true since we're looking for a value that is less than 17 not less than or equal to 17. So in conclusion, if x≤11 ( if x is less than or equal to 11), my statement will be true because 11+5<17=16<17, which is true. Even 10 or less is fine because it will still be smaller than 17 and that will keep my statement balanced.

9x = 63
9x ÷ 9 = 63 ÷ 9
x = 7
Answer:
9x + 4 + 180 + 113=360
9x + 297=360
9x=360-297

Answer:
a = 9 / 7
step by step explanation:
9 / - a + 15 = 8
Determined the defined range
9 / ( - a ) + 15 = 8 , a ≠ 0
subtract 15 from each side
9 / - a + 15 - 15 = 8 - 15
calculate the difference
9 / - a = - 7
multiply both side of equation by - a
9 / - a × - a = - 7 × - a
9 = 7 a
divide each side by of equation by -7
9 / 7 = 7 a / 7
9 / 7 = a
swap the side of equation . ( optional )
a = 9 / 7
