Answer:
4 cans of paint will cover 8/9 of the surface
Step-by-step explanation:
One can of paint covers 2/9 of the house.
Garvin has used 4 of those cans.
To get the fraction of the whole surface that has been covered by those 4 cans of paint, we can multiply, following the logic below:
1 can of paint covers = 2/9 of the surface
4 cans of paint will cover = x of the surface
x = 4 X 2/9 = 8/9
Therefore, 4 cans of paint will cover 8/9 of the surface
determine the equation of the line that passes through points (-4,5) and has a slope of m = -3
Answer:
y=-3x-7
Step-by-step explanation:
You want to find the equation for a line that passes through the point (-4,5) and has a slope of -3.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was -3. So you can right away fill in the equation for a line somewhat to read:
y=-3x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(-4,5). When x of the line is -4, y of the line must be 5.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the -3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-4,5).
So, why not plug in for x the number -4 and for y the number 5? This will allow us to solve for b for the particular line that passes through the point you gave!.
(-4,5). y=mx+b or 5=-3 × -4+b, or solving for b: b=5-(-3)(-4). b=-7.
The graph shows the amount of money paid when purchasing bags of candy at the zoo:
A graph is shown. The x-axis is labeled from 0 to 9. The y-axis is labeled from 0 to 10. Four points are shown on the graph on ordered pairs 0, 0 and 1, 2 and 2, 4 and 3, 6. These points are joined by a line. The label on the x-axis is Bags of candy. The title on the y-axis is Total cost in dollars.

Michael is riding his tricycle, he has a head start of 5 meters and is pedaling at 2 meters every 3 seconds. What is the equation of the line? What is the independent and dependent variables?
Answer:
The correct answer is
y = 2 ÷ 3x + 5
where,
x = independent variable
y = dependent variable
Step-by-step explanation:
According to the given scenario, the equation of the line, independent and the dependent variable is as follows:
y = mx + b
Since the head is started with 5 meters and the pedaling at 2 meters for every 3 seconds i.e. 2 ÷ 3
So the equation line is
y = 2 ÷ 3x + 5
where,
x = independent variable
y = dependent variable

Find the missing side of the triangle. Side LaTeX: cc is the hypotenuse and sides LaTeX: aa and LaTeX: bb are legs. Leave your answer in simplest radical form. LaTeX: a=2,\:b=4
Answer:
[tex]c = 2\sqrt{5[/tex]
Step-by-step explanation:
Given
[tex]a = 2[/tex]
[tex]b = 4[/tex]
c = hypotenuse
Required
Find c
Using Pythagoras theorem, we have:
[tex]c^2 = a^2 + b^2[/tex]
Substitute values for a and b
[tex]c^2 = 2^2 + 4^2[/tex]
[tex]c^2 = 4 + 16[/tex]
[tex]c^2 = 20[/tex]
Take square roots of both sides:
[tex]c = \sqrt{20[/tex]
Express 20 as 4 * 5
[tex]c = \sqrt{4 * 5[/tex]
Split surd
[tex]c = \sqrt{4} * \sqrt{5[/tex]
Take square root of 4
[tex]c = 2 * \sqrt{5[/tex]
[tex]c = 2\sqrt{5[/tex]
1.) Solve the system of equations by method of elimination. Show all your work.
2x + 4y = 8
10x – 4y = 16
Answer:
x=2, y=1
Step-by-step explanation:
Add:
2x+4y=8
+10x-4y=16
------------------
12x=24
Divide by 12 on both sides:
x=2
Substitute x with 2 on either 2x+4y=8 or 10x-4y=16 it doesn't matter it will result in the same answer.
(I will do both of them to prove it but you only need to replace x with one of the equation)
For 2x+4y=8
2(2)+4y=8
4+4y=8
Subtract 4 on both sides
-4+4+4y=8-4
4y=4
Divide 4 on both sides:
y=1
For 10x-4y=16
10(2)-4y=16
20-4y=16
-20+20-4y=16-20
-4y=-4
Divide -4 on both sides:
y=1
The answer for both 2x + 4y = 8 and 10x – 4y = 16 are the same showing that it doesn't matter which equation you replace the number with it will still result you in the same answer
Hope this helps!

I need help with just the last question! :)
Answer:
the answer is 260
Step-by-step explanation:
Plug 20 in for x in the equation.
a) 94x^2+15x-25
b)34^2+15x-25
c)27x+3
d)34x^2-15x-25
Answer:
d) 34x^2 - 15x -25
( (8x + 5) * (8x - 5) ) - 5x(6x +3 )
= 64x^2 - 25 - 30x^2 - 15x
= 34x^2 - 15x - 25

[tex] \cos(30°) = \frac{16 \sqrt{3} }{s} \\ [/tex]
[tex] \frac{ \sqrt{3} }{2} = \frac{16 \sqrt{3} }{s} \\ [/tex]
Inverse both sides
[tex] \frac{2}{ \sqrt{3} } = \frac{s}{16 \sqrt{3} } \\ [/tex]
[tex] \frac{s}{16 \sqrt{3} } = \frac{2}{ \sqrt{3} } \\ [/tex]
Multiply sides by 16√3
[tex]16 \sqrt{3} \times \frac{s}{16 \sqrt{3} } = 16 \sqrt{3} \times \frac{2}{ \sqrt{3} } \\ [/tex]
[tex]s = \frac{2 \times 16 \times \sqrt{3} }{ \sqrt{3} } \\ [/tex]
[tex]s = 32[/tex]
Thus the correct answer is Option D .
