Answer:
7x + 6y = 6
Step-by-step explanation:
x - 2y = - 1..... (1)
8x + 4y = 5...(2)
Subtracting equation (1) from equation (2)
8x + 4y - ( x - 2y) = 5 - (-1)
8x + 4y - x + 2y = 5 + 1
8x - x + 4y + 2y = 6
7x + 6y = 6
Can anyone answer this?
Step-by-step explanation:
a) First we will convert 150km/hr to m/s.
[tex] \frac{150km}{1hr} = \frac{(150 \times 1000)m}{(1 \times 60)s} \\ = \frac{150000m}{60s} \\ = 2500m \: per \: second[/tex]
=2500m/s, which is the initial speed of the plane.
b)Final Speed of plane = Speed when it stopped.
= 0m/s.
c)Time taken to stop = 3 seconds.
d)Using the kinematic equation,
v = u + at,
where v = Final Speed = 0m/s
u = Initial Speed = 2500m/s
a = acceleration
t = time taken = 3 seconds
Substitute v, u and t to find a.
[tex]0 = 2500 + 3a \\ 3a = - 2500 \\ a = - 2500 \div 3 \\ = - 833 \frac{1}{3} \frac{m}{ {s}^{2} } [/tex]
What is the length of the leg
Answer:
The length of the leg is 8.7
Step-by-step explanation:
Formula:
a = √(c² - b²)
Substitute 9 for c and 2 for b:
a = √(9² - 2²)
a = √(81 - 4)
a = √77
a = 8.77496438739

Write a linear equation in slope intercept form using the given point and slope.
(6,-6); slope = 2/3
Answer:
2/3x-10
Step-by-step explanation:
y=mx+b
y=2/3x+b
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(6,-6). When x of the line is 6, y of the line must be -6.
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 2/3 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 (6,-6).
So, why not plug in for x the number 6 and for y the number -6? This will allow us to solve for b for the particular line that passes through the point you gave!.
(6,-6). y=mx+b or -6=2/3 × 6+b, or solving for b: b=-6-(2/3)(6). b=-10.
so, y=2/3x-10

Step-by-step explanation:
what is the average rate of change of the function f(x) over the interval [1,3] rounded to the nearest whole number f(x)=6(2.5)
Answer:
[f(1) - f(3)] / [1–3]
Step-by-step explanation:
Formula
f(x) = 6(2.5)
How to find
The average rate of change over the interval [a,b], or the secant line between the points a and b on the function f(x), is [f(a) - f(b)]/[a-b]. So, substitute a for 1 and b for 3, and you get [f(1) - f(3)] / [1–3]. The quotient of that is your average rate of change.

What is 2.4% as a decimal
Answer:
2.4% as decimal will be 0.024.
Step-by-step explanation:
1) To convert to a decimal, divide the percent number by 100.
[tex]2.4 \div 100 = 0.024[/tex]
2) Therefore, the decimal form is 0.024.
[tex]0.024[/tex]
2.4% is equivalent to 0.024 as a decimal.
To convert 2.4% to a decimal, we divide the percentage value by 100. In this case, we divide 2.4 by 100:
2.4% = 2.4 / 100 = 0.024
Therefore, 2.4% as a decimal is 0.024.
When we convert a percentage to a decimal, we move the decimal point two places to the left. This is because a percentage is a value expressed as a fraction of 100. So, to express 2.4% as a decimal, we divide 2.4 by 100, resulting in 0.024.
To understand this conversion, consider that 100% is equivalent to the whole value, which is represented as 1 in decimal form. Any percentage less than 100% will be a fraction of that whole, expressed as a decimal less than 1. In this case, 2.4% is a small fraction of 1, which is 0.024.

Find the volume of the figure
Answer:
132 yd³
Step-by-step explanation:
To find the volume of a triangular prism, use this equation: V = (1/2bh) * h
V = (1/2(11 * 4)) * 6
Step 1: Multiply 11 by 4 to get 44.
V = (1/2(44)) * 6
Step 2: Multiply 1/2 by 44 to get 22.
V = 22 * 6
Step 3: Multiply 22 by 6 to get 132.
V = 132
The volume of the figure is 132 yd³.
