Q3). 0.4x + 0.3y = 1.7
0.7x - 0.2y = 0.8
Solve it by using substitution method.
[tex]▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ { \huge \mathfrak{Answer}}▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ [/tex]
The values of :
[tex]x = 2[/tex][tex]y = 3[/tex]The given equations are :
[tex]0.4x + 0.3y = 1.7[/tex][tex]0.7x - 0.2y = 0.8[/tex]now, let's multiply both the equations with 10 on both sides.
so, now our equations will be :
[tex]4x + 3y = 17[/tex][tex]7x - 2y = 8[/tex]from Equation second :
[tex]7x - 2y = 8[/tex][tex]2y = 7x - 8[/tex][tex]y = \dfrac{7x - 8}{2} [/tex]now, let's substitute the value of y from here into Equation first.
[tex]4x + 3y = 17[/tex][tex]4x +3 \bigg ( \dfrac{7x - 8}{2} \bigg) = 17[/tex][tex]4x + \dfrac{21x - 24}{2} = 17[/tex][tex] \dfrac{8x + 21x - 24}{2} = 17[/tex][tex] \dfrac{ 29x - 24 }{2} = 17[/tex][tex]29x - 24 = 34[/tex][tex]29x = 34 + 24[/tex][tex]29x = 58[/tex][tex]x = \dfrac{58}{29} [/tex][tex]x = 2[/tex]here, we got the value of x = 2, let's plug it in equation second to find value of y :
[tex]7x - 2y = 8[/tex][tex]7(2) - 2y = 8[/tex][tex]14 - 2y = 8[/tex][tex]2y = 14 - 8[/tex][tex]2y = 6[/tex][tex]y = \dfrac{6}{2} [/tex][tex]y = 3[/tex]And value of y = 3
Alice earns $185 for working 14.8 hours each week. How much money will Alice earn if she increased her hours to 18 1/2 hours per week?
:)
Step-by-step explanation:
185 is to 14.8 as x is to 18.5
185/14.8 = x/18.5
x = 185(18.5)/14.8
x = $231.25

Answer:
69 degrees
Step-by-step explanation:
m is a point, if your trying to find lkh, is 69
lkm=111, and jkl=180, so 180-111=jkm
jkm=69
angles that are diagonal from each other are the same degree
lkh=69

Answer:
- 5 [tex]\frac{5}{8}[/tex]
Step-by-step explanation:
[tex]\frac{m}{-\frac{6}{5} }[/tex] , is equivalent to
m ÷ - [tex]\frac{6}{5}[/tex] , substitute given value of m
= 6 [tex]\frac{3}{4}[/tex] ÷ - [tex]\frac{6}{5}[/tex] ( change mixed number to improper fraction )
= [tex]\frac{27}{4}[/tex] ÷ - [tex]\frac{6}{5}[/tex] ( leave first fraction, change ÷ to × , flip second fraction )
= [tex]\frac{27}{4}[/tex] × - [tex]\frac{5}{6}[/tex] ( cancel 27 and 6 by 3 )
= [tex]\frac{9}{4}[/tex] × - [tex]\frac{5}{2}[/tex] ( multiply values on numerator/ denominator )
= - [tex]\frac{9(5)}{4(2)}[/tex]
= - [tex]\frac{45}{8}[/tex]

What is the amplitude of this graph? On a coordinate plane, the points on a function curve are shown. The curve crosses the y-axis at (0, 5) and then decreases to the minimum. The minimum is indicated by a green point. The minimum is at (0.748, 2) and the maximum is at (1.870, 6). After the green point, the curve increases and then decreases again.
Answer:
here are the answers! :)
Step-by-step explanation:
The value represents the amplitude of the function. Therefore, the amplitude of the cosine curve function of the graph is 2.
What is the amplitude of a function?The amplitude of a function is simply the maximum point or value of the given function.
From the question, we have:
Maximum = 2
The value represents the amplitude of the function.
Therefore, the amplitude of the cosine curve function of the graph is 2.
