Answer:
On a coordinate plane, a line has a negative slope
Step-by-step explanation:
If a graph only shows one line, there is an infinite amount of solutions. We need two separate line equations to cross at a point in order to find the solution to the system. However, if a graph shows two parallel lines that never cross, there are no solutions to that systems of equations.
Answer:
Step-by-step explanation:
Dad: 2/5
Son: 1/3
<u>Who mowed most of the lawn? </u> Dad, of course. 2/5 is larger than 1/3. 2/5 is 40% and 1/3 is 33.333%
<u>How much of the lawn still needs to be mowed? </u>
2/5 + 1/3 + X = 1 [1 means the whole lawn. X is the remaining portion.]
6/15 + 5/15 + X = 1 [Convert each fraction so that they have a com,mon denominator. This also shows that 2/5 (6/15) is larger than 1/3 (5/15).
11/15 + X = 1
X = 1 - 11/15
X = 4/15 left to be mowed.
<u>How much does Mr. Doyle have left to mow?</u>
We'll assume each rate is the same, 2/5 for Dad and 1/3 for son.
4/15 left to be mowed.
Dad will mow 2/5 of 4/15, so (2/5)*(4/15) = 8/75 left of the original yard
Son will mow 1/3 of 4/15, so (1/3)*(4/15) = 4/45 left of the original yard
Answer:
C) 63.2 cm^2
Step-by-step explanation:
Square: (b)(h) = 6 cm x 7.2 cm = 43.2^2
Subtract 10 from 6 to get the width of the rectangle.
Rectangle: (b)(h) = 4 x 2.8 = 11.2 cm^2
To find the triangle, subtract 7.2 with 2.8 and subtract 10 with 6.
Triangle: (1/2)(b)(h) = (1/2)(4)(4.4) = (1/2)(17.6) = 8.8 cm^2
Now, add everything together.
43.2 + 11.2 + 8.8 = 63.2 cm^2
(x + 10) (x + 10) = 0
This equation is saying that x plus 10 is equal to zero. It basically means that both expressions are equal to 0.
For example (3x + 4) (2x - 5) = 0
Both terms are equal to zero. So to find x you would have to solve for x.
x + 10 = 0
x = -10
