Answer:
There is no graph.
Step-by-step explanation:
A. 2x+y=25; x+y=20
x represents cheese wafers and y represents chocolate wafers.
B. I will choose elimination since there is y and y. I can multiply one equation by -1 to get y and -y, which cancels out.
2x+y=25
-x-y=-20
Add equations
x=5
Plug x in
5+y=20
y=15
Final answer: 5 cheese wafers, 15 chocolate wafers
Answer:
Step-by-step explanation:
<em>(17).</em> g(x) = x³ + 4x
f(x) = 4x + 1
( f × g )( x ) = ( x³ + 4x )( 4x + 1 ) = <em>4 </em>
<em> + x³ + 16x² + 4x</em>
<em>(19).</em> f(t) = 4t - 4
g(t) = t - 2
( 4f + 3g )( t ) = 4(4t - 4) + 3(t - 2) = 16t - 16 + 3t - 6 = <em>19t - 22</em>
<em>(21).</em> h(t) = t + 3
g(t) = 4t + 1
h(t - 2) + g(t - 2) = ( t - 2 ) + 3 + 4( t - 2 ) + 1 = t + 4t - 2 + 3 - 8 + 1 = <em>5t - 6</em>
Answer:
6/30
Step-by-step explanation:
20 percent of 30 is 6 ^_^
The total number of members should be the sum of the number of men, x, and women, y, and that should be equal to 150. In mathematical equation that should be,
<em>x + y = 150</em>
If we are to note that there are 34 more men than women in the team, we can say that,
y = x - 34
The equation then would become,
x + (x - 34) = 150
The value of x from the equation is equal to 92. With this, the number of the women is equal to 58.
