we know that
The algebraic expression of the phrase " The sum of square of c and d" is equal to adds the square of number c to the number d
The algebraic expression of the phrase " The sum of square of c and d increased by twice their product" is equal to
Answer:
x,y
Step-by-step explanation:
because it shows range and dange
Answer:
Y is going to triple(y1=3y)
Step-by-step explanation:
y=5/x;
x triples means y1=5/(3x);
Y1 divided by y, we get (5/x)/(5/3x)=(5/x)*(3x/5)=3
7x+1y = 17.00 can be simplified to y = -7x +17
<span>-7x +17 can then be substituted for y in 3x+ 4y =17.50
</span>3x+4(y) = 17.50
3x+ 4(-7x +17) = 17.50
From here you can solve for X
<span>3x + 4(-7x +17) = 17.50
</span>3x -28x + 68 = 17.50
-25x + 68 = 17.50
-68 -68
-25x = -50.50
÷-25 ÷-25
X = 2.02
You can then replace x with 2.02 in the original 7x + 1y = 17.00 to solve for y.
7(x) + 1y = 17.00
7(2.02) + y = 17.00
14.14 + y = 17.00
-14.14 -14.14
y = 2.86
Then substitute 2.02 for x and 2.86 for y in the original 3x+ 4y = 17.50 to check.
3(x) + 4(y) = 17.50
3(2.02) + 4(2.86) = 17.50
6.06 + 11.44 = 17.50
17.50 = 17.50
So
X = 2.02
and
Y = 2.86
or the solution set is (2.02, 2.86)
Hope this helps
<span>f+0.2=−3
subtract 0.2 to both sides
f + 0.2 - 0.2 = -3 - 0.2
simplify
f = -3.2
answer is </span><span>f = 3.2</span>
