Step-by-step explanation:
2x + y + x+ 2y = 180
3x + 3y = 180
3y +20+2x+y=180
4y + 2x = 160
3x + 3y = 180
2x + 4y = 160
elimination
6x + 6y= 360
6x + 12y = 480
= 6y = 120
y= 20
substitute
3x + 3y = 180
3x + 3(20)= 180
3x + 60 = 180
3x = 120
x= 40
x+2y

Help me solve the following formula for v1
Answers
Answer:
v1 = at + v0
Step-by-step explanation:
We want to end up with a formula that looks like v1 = algebraic expression
Start by multiplying both sides of the given formula by t, to eliminate fractions:
at = v1 - v0
Next we isolate v1 by adding v0 to both sides of the above equation:
at + v0 = v1 - v0 + v0, or v1 = at + v0

What is the equation of the line that passes through the point (8,1) and has a slope
of –3/4?
Answers
Answer:
[tex]y=-\frac{3}{4}x+7[/tex]
Step-by-step explanation:
The slope is already given as [tex]-\frac{3}{4}[/tex] so all we have to do is solve for y-intercept
First, write the equation in slope-intercept form
[tex]y=-\frac{3}{4}x+b[/tex]
Next, use the point to substitute the x and y value and solve for the y-intercept
[tex]y=-\frac{3}{4} x+b[/tex] where b = y-intercept
point: (8, 1)
[tex]1=-\frac{3}{4}(8)+b[/tex]
Then multiply 8 and -3/4
[tex]1=-6+b[/tex]
Finally, solve for the b (y-intercept)
b = [tex]1--6[/tex]
b = 7
so the y-intercept is 7
And the equation of the line that passes through the point (8, 1) and has a slope of -3/4 is [tex]y=-\frac{3}{4}x+7[/tex]

Three-quarters of a number is 2 bigger than two-thirds of the number.
Determine the number.
Answers
Answer:
0
Step-by-step explanation:
3/4.x = 2. 2/3.x
↔ x = 0
The required number after simplification of the given statement of the equation is equal to 24.
Let's call the number we want to find "x."
According to the given information:
Three-quarters of the number is 2 bigger than two-thirds of the number.
Mathematically, we can express this as the following equation:
(3/4) × x = (2/3) × x + 2
Now, let's solve for "x":
Get rid of the fractions by multiplying everything by the least common multiple (LCM) of 4 and 3, which is 12.
12× (3/4) × x = 12 × (2/3) × x + 12× 2
Simplify both sides:
9x = 8x + 24
Isolate the "x" term on one side. To do this, we need to move the 8x to the left side by subtracting 8x from both sides:
9x - 8x = 8x + 24 - 8x
Simplify further:
x = 24
Therefore, the number after simplification is 24.

I need help guys like rn please someone!!
Answers
Answer:
B
Step-by-step explanation:
The correct answer is B, because you have -4 +(-6)+(-2) which is really just
-4-6-2 which is -12. Think of it as getting rid of the plus sign and just leaving the negative sign. Which this would make the answer to the equation be -12, but for the answer of the question, it would be B because it is accumulating the drops in temperatures making the numbers go down in temperature, therefore making them negative.
A is not the answer because although it is similar to letter B, the difference is the final sentence, "What was the overall change in temperature?" Since -4 is listed as the pre-existing temperature, that would make -6 - 2 be equal to negative eight (-8).
C is not the answer because it includes a temperature rising by 18 degrees.
D is not the answer either because it is saying the temperature rose, which is shouldn't have risen.
The only time C and D could be right, is if they included bigger number that equaled out to negative twelve (-12), like saying the temperature rose 18 degrees, but fell by 26 degrees by midnight, that would make the equation look like -4 + 18 - 26 = - 12
Even in that case, C and D would be wrong immediately because of the use of numbers outside of the expression given.

Answer:
14
Step-by-step explanation:
f(x) = 3x² - x
To find f(-2), substitute -2 for x into the function f.
f(-2) = 3(-2)² - (-2)Now, use PEMDAS to evaluate the function.
Start by evaluating the exponent.
f(-2) = 3(4) - (-2)Next, multiply 3 and 4 and -2 by -1.
f(-2) = 12 + 2Add the two terms together.
f(-2) = 14The correct answer is f(-2) = 14.

The product 2+bi)(3+2i) is equal to 13i. What is the value b?
Answers
Answer:
[tex]b = 3[/tex]
Step-by-step explanation:
We are given that:
[tex](2 + bi)(3+2i) = 13i[/tex]
And we want to determine the value of b.
First, expand:
[tex]\displaystyle \begin{aligned} (2+bi)(3+2i)&=2(3+2i)+bi(3+2i) \\ &= (6+4i)+(3bi+2bi^2) \\ &= (6+2b(-1))+(4i+3bi) \\ &= (6-2b) + (4+3b)i\end{aligned}[/tex]
Therefore, we can write that:
[tex](6-2b) + (4+3b)i = 0+ 13i[/tex]
If two complex numbers are equivalent, their real and imaginary parts must be equivalent. Hence:
[tex]6-2b = 0 \text{ and } 4+3b = 13[/tex]
Solve for each case:
[tex]b=3 \text{ and } b=3[/tex]
The two solutions are equivalent, hence such a number b exists.
In conclusion, b = 3.

It looks impossible to tell if you don't know one simple fact. You have to know that the Plane that contains WTSR and V is opaque which means you can't see through it. So the line that goes through it (containing WQ) is partially not seen.
It is represented by a dashed line that shows the line is there, but it is invisible.
So Q is on the plane, but W is not. W is the answer.
