Step-by-step explanation:
<u>Step 1: Define Systems</u>
a + 4b = -4
a + 10b = -16
<u>Step 2: Rewrite Systems</u>
a + 4b = -4
- Subtract 4b on both sides: a = -4 - 4b
<u>Step 3: Redefine Systems</u>
a = -4 - 4b
a + 10b = -16
<u>Step 4: Solve for </u><em><u>b</u></em>
<em>Substitution</em>
- Substitute in <em>a</em>: -4 - 4b + 10b = -16
- Combine like terms: -4 + 6b = -16
- Isolate <em>b</em> term: 6b = -12
- Isolate <em>b</em>: b = -2
<u>Step 5: Solve for </u><em><u>a</u></em>
- Define equation: a + 4b = -4
- Substitute in <em>b</em>: a + 4(-2) = -4
- Multiply: a - 8 = -4
- Isolate <em>a</em>: a = 4
Answer:
From top to bottom;
1,1,3,3
Step-by-step explanation:
mathematically, for an even function;
f(x) = f(-x)
what this mean is that;
f(-1) = f(1)
f(-3) = f(3)
f(-5) = f(5)
f(-6) = f(6)
so we have it that;
f(-1) = 1
f(-3) = 1
f(-5) = 3
f(-7) = 3
It seems that you have missed the necessary options for us to answer this question, but anyway, here is the answer.
Based on the given scenario above, the expression would be this:
<span> a + c = 2904
12a + 6.5c = 27,126
</span>Wherein a is for adult, and c is for children.
Here is the solution:
a + c = 2904
a = 2904 - c
Next,
12 (2904-c) + 6.5c = 27,126
34,848 - 12c + 6.5c = 27,126
-5.5c = 27,126 - 34, 848
-5.5c = - 7,722 (divide both sides by -5.5)
c = 1,404
Now going back to the first expression:
a + c = 2904
a + 1,404 = 2904
a = 2904 - 1,404
a = 1500
Hope this answer helps.
Answer:
x=6
y=3
Step-by-step explanation:
y(side)= x
x(side)=2x
3rd side (3
) = x![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
x=3;
x= 2(3)=6
y=(3)=3
