Answer:
1) x-intercept= (-6,0) y-intercept= (0,-3)
2) x-int= (2,0) y-int= (0,-5)
Step-by-step explanation:
Answer:
1) x = 2 and y = -4
2) x = 4 and y = 5
Step-by-step explanation:
to check if it's correct, simply plug in the numbers to the x and y value.
1) 2 + 2(-4)
2 + -8 = -6
(x + 2y = -6)
2) 5(4) - 2(5)
20 - 10 = 10
(5x - 2y = 10)

Step-by-step explanation:
Brainliest?
We want to rewrite the given expression as a square of a monomial. We will get:
0.09*a^2 = (0.3*a)^2
So we have the expression:
0.09*a^2
We want to write this as a square of a monomial like:
(c*a)^2 = 0.09*a^2
Basically, we must find a number c such that:
c^2 = 0.09
c = √(0.09) = 0.3
Then the monomial is:
0.3*a
And we can rewrite the given expression as:
(0.3*a)^2

Joe has eaten 2/5 of a pizza.Jane has eaten 1/6 of a pizza how many more pizza has joe eaten than Jane?
Answers
Joe ate 7/30 more of pizza than Jane. You can just subtract 2 uneven denominators. So you would turn them into 30 because that’s the closest highest number that can go with 5 and 6. Then multiply 2 with 6 which is 12 and then multiply 1 with 5 which is 5 now you can subtract it. 12/30-5/30=7/30.
Final Result: 7/30

Answer:
y = $19.50
x = $17.17
z = $20.67
Step-by-step explanation:
Notice that $13.50 of $22.50 is 60% (in math decimal form 0.6). The same is true for $16.20 of $27.00. Therefore, the value of y is going to be :
0.6 * $32.50 = $19.50
We notice as well that the added taxes to the discount price $13.50 is:
14.31 - 13.5 = $0.81, which at a time is a percent of the discounted sales price. Such percentage is calculated as shown below:
0.81/13.5 = 0.06 (or 6%)
we can then add 0.06 * 16.20 = 0.972 to 16.20 to find the total price "x"that includes tax:
x = $16.20 + $0.97 = $17.17
And we do something similar to find z:
z = $20.67

6:6=x
7:16=y
8:20=z
Step-by-step explanation:
For 6, since BD is a perpendicuar bisector, that means 15x=90. Divide 90 by 15 and you get 6
for 7, if bd is a angle bisector, you can set 3y=48. divide 48 by 3 and you get 16
for 8, since Bd is a median, you can set 2z-3=z+17. Isolate the variable and you will get 2z-z=17+3. Add like terms together and you get z=20
Just so you know, a perpendicular bisector will make both angles equal to 90, an angle bisector make both angles equal to each other, and medians make it so that it hit a line in the center therefor you can set both sides of the line to be equal

Peter has a 25 acre field. He 20.5 acres with sweet corn . What fraction of his field does Peter plant with sweet corn
Answers
Answer:
82%
Step-by-step explanation:
Multiply 25*4 to get 100.
Then multiply 20.5*4 because what you do to one side you have to do for the other.
You end up with 0.82 or 82%
Based on the length of the field and the amount of the field that was planted the fraction of the field planted is 4.1/5.
The field has a length of 25 acres and Peter plants in 20.5 acres of them.
The fraction that is planted is:
= Amount of field planted on / Total area of field
Solving will give:
= 20.5 / 25
Take to the simplest form by dividing both by 5:
= 4.1 / 5
In conclusion, the fraction planted on is 4.1/ 5.

=36The volume of a cube is increasing at a constant rate of 459 cubic inches per second. At the instant when the volume of the cube is 408 cubic inches, what is the rate of change of the surface area of the cube? Round your answer to three decimal places (if necessary).
Answers
Answer:
[tex]\frac{ds}{dt} =31.952[/tex]
Step-by-step explanation:
From the question we are told that
Cube increase rate 459 cubic inches
At 408
Generally the expressions of the is mathematically given to be
[tex]\frac{dv}{dt} =459[/tex]
[tex]\frac{dv}{dt} =3*l^2 \frac{dl}{dt}[/tex]
[tex]v=408[/tex]
Generally
[tex]v=l^3[/tex]
Therefore solving Mathematically
[tex]\frac{dv}{dt} =3*l^2 \frac{dl}{dt}[/tex]
[tex]459 =3*(7.416859539)^2 \frac{dl}{dt}[/tex]
[tex]459 =165.0294163\frac{dl}{dt}[/tex]
[tex]\frac{dl}{dt} =\frac{165.0294163}{459}[/tex]
[tex]\frac{dl}{dt} =0.359[/tex]
Therefore solving mathematically for surface area
[tex]Surface area S=6l^2[/tex]
[tex]\frac{ds}{dt} =6(2l* \frac{dl}{dt})[/tex]
[tex]\frac{ds}{dt} =12l* \frac{dl}{dt}[/tex]
[tex]\frac{ds}{dt} =12*(7.416859539)*0.359[/tex]
[tex]\frac{ds}{dt} =31.95183089[/tex]
[tex]\frac{ds}{dt} =31.952[/tex]

you are rolling a die number 1-6. What is the theoretical probability that you roll a 6?

So to get a 6 when rolling a six-sided die, probability = 1 ÷ 6 = 0.167, or 16.7 percent chance. So to get two 6s when rolling two dice, probability = 1/6 × 1/6 = 1/36 = 1 ÷ 36 = 0.0278, or 2.78 percent.
