Answer:
Your solution is (-11/6, 7/6).
Step-by-step explanation:
-2x + 2y = 6
4x + 2y = -5
Right away I can see that our y-values are the same. We want to eliminate one variable at a time, so let's make one of the 2y's a positive by multiplying each term in the equation by -1.
4x + 2y = -5
-1(4x + 2y = -5)
-4x - 2y = 5
Now we have a new equation in our system.
-2x + 2y = 6
-4x - 2y = 5
Now eliminate by performing each action given by the terms.
-2x + 2y = 6
-4x - 2y = 5
_________
-6x = 11
Divide both sides by -6.
x = 11/-6
Now that we know x, plug it back into one of the original equations to find y.
-2x + 2y = 6
-2(11/-6) + 2y = 6
Multiply.
-22/-6 + 2y = 6
22/6 + 2y = 6
Subtract 22/6 from both sides.
2y = 6 - 22/6
2y = 36/6 - 22/6
2y = 14/6
2y = 7/3
Divide both sides by 2.
y = (7/3)/2
y = 7/6
Your solution is (-11/6, 7/6).
Check your answer by plugging both values into one of the original equations.
4x + 2y = -5
4(-11/6) + 2(7/6) = -5
Multiply.
-44/6 + 14/6 = -5
Add.
-30/6 = -5
Divide.
-5 = -5
Your answer is correct.
Hope this helps!

Solve the equation 3(+4.5)=36
What is the value of x?
Answer:
x=7+1/2
Step-by-step explanation:
We move all terms to the left:
3(x+4.5)-(36.)=0
We add all the numbers together, and all the variables
3(x+4.5)-36=0
We multiply parentheses
3x+13.5-36=0
We add all the numbers together, and all the variables
3x-22.5=0
We move all terms containing x to the left, all other terms to the right
3x=22.5
x=22.5/3
x=7+1/2
The formula for the surface area of a rectangular prism with a square base is SA = 2s2 + 4sh. What is the surface area of this rectangular prism if s = 3 and h = 6?
Answer:
90
Step-by-step explanation:
Step 1: Given data
Side of the rectangular prism (s): 3
Height of the rectangular prism (h): 6
Step 2: Calculate the surface area (SA) of the base
We will use the following expression, replacing the values for s and h.
SA = 2 × s² + 4 × s × h
SA = 2 × 3² + 4 × 3 × 6 = 90
The units are not provided but the SA should have the same units as s and h, but raised to the power of 2.

Ahmad and 19 of his friends won a competition.they shared the prize money of $70,000 equally.ahmad saved $2500 of his share and donated the rest.How much did ahmad donate?
==========================================================
Explanation:
There are 1+19 = 20 people total. The prize money $70,000 is divided among those 20 people equally to get (70,000)/20 = 3500 dollars per person.
Ahmad saves $2500 of his $3500 prize, leaving 3500-2500 = 1000 dollars leftover. This is the amount he donates.

I'm sorry I'm unsure how to solve the last question.
Austin’s monthly gross pay is $4,200. Federal withholding is 16.05% of his pay. His other deductions total $321.30. What is his net pay.
Answer:
$3,204.6
Step-by-step explanation:
$ 4,200 represents 100% of his salary
x amount of $ represents 16.05 % in federal withholding
after you line up $ with $ and % with % think cross multiplication
x = 4,200* 16.05/ 100 = $674.1 is the amount in federal withholding
Net pay = 4,200 -674.1 -321.30 = $3,204.6
Set up an equation for the value of x.
Answer:
x = 27
Step-by-step explanation:
∠ GAF = 90° , then
x + 63 = 90 ( subtract 63 from both sides )
x = 27
Answer:
27
Step-by-step explanation:
Angle x and 63 are complementary angles forming 90
Therefore,
90 - 63 = x
27 = x
If x is an even number , the function f(x) = 2x-1 gives an odd number. Identify the set of odd numbers corresponding to this set of even numbers: {0,2,4,6,8}
Answer:
{-1, 3, 7, 11, 15}
Step-by-step explanation:
f(x) = 2x − 1, {0, 2, 4, 6, 8}
f(0) = 2*0 − 1 = 0 - 1 = -1
f(2) = 2*2 − 1 = 4 - 1 = 3
f(4) = 2*4 − 1 = 8 - 1 = 7
f(6) = 2*6 − 1= 12 - 1 = 11
f(8) = 2*8 − 1= 16 - 1 = 15

Keisha's softball team won 60% of 135 games, how much games did the team lose?
Answer:
54
Step-by-step explanation:
135(.6) = 81
total = 135
won = 81
lost = 54
OR you could just multiply 135 by 110%-60%, which is 40% or 0.4
135(.4) = 54

What type of conic section is represented by the parametric equations below? X=3cos(t)-1 y=3sin(t)+4
Answer:
Circle
Step-by-step explanation:
Examples of conic sections are the circle, the ellipse, the parabola and the hyperbola. Parametric equations are used to express the x and y variables in terms of a less complicated manner using a third variable (t or θ).
The parametric equation for a circle with an equation [tex](x-h)^2+(y-k)^2=r^2[/tex] is given by:
[tex]x=rcos(t)+h, y=rsin(t)+k[/tex]
where r is the radius of the circle and (h, k) is the center of the circle.
A conic section with a parametric equations X=3cos(t)-1, y=3sin(t)+4 is a circle with center at (-1, 4) and radius of 3. The equation of the circle is:
(x + 1)² + (y - 4)² = 3²
It’s 28 : 12
because we have the equation
7 : 3 which if you multiply both of
those by 4 you’ll get 28 : 12
