Answer:
18
Step-by-step explanation:
168 : 28 : : 108 : y
168 / 28 = 108 / y
6 = 108 / y
6 * y = 108
y = 108 / 6
y = 18
Answer:
y = 18
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 28 when x = 168
28 = 168k ( divide both sides by 168 )
[tex]\frac{28}{168}[/tex] = k , that is
k = [tex]\frac{1}{6}[/tex]
y = [tex]\frac{1}{6}[/tex] x ← equation of variation
When x = 108 , then
y = [tex]\frac{1}{6}[/tex] × 108 = 18

-2(x + 3) = -2(x + 1) - 4
Answer:
infinite solution
Step-by-step explanation:
-2 times x is -2x
-2 times 3 is -6
-2 times x is -2x
-2 times 1 is -2
the equation now looks like this:
-2x-6=-2x-2-4
Simplify
-2x-6=-2x-6
0=0
So this is an infinite solution

Answer:
6 favors each guest
Step-by-step explanation:
3 bag if 12 means total 36
She has divided evenly amongst 6 guest .
36/6 = 6each guest.
Answer:
The answer would be 6.
Step-by-step explanation:
Assuming, Amy doesn't have a sweet tooth, she's only giving party favors to her own guests.
There are 3 bags of 12 party favors each. This gives us a total of 36 party favors.
There are 6 guests and so to evenly split the party favors, we must split 36 into 6 groups, giving us 6 party favors in each group.
COMPUTATION:
3 x 12 = 36
36 / 6 = 6
Hope this helps!

Answer:
a is less than or equal to 7
Step-by-step explanation:
This is the case because we can treat the less than or equal to sign as an equal sign. The only time it changes is when we divide by a negative, but we do not do that in this problem. First, you subtract 7 from both sides. That leaves us with a 4a on one side and a 28 on the other. Then, you divide both sides by four to get a is less than or equal to 7. I hope this helps!

Which point is an x-intercept of the quadratic function
f(x) = (x – 3)(x + 2)?
A(3, 0)
B(0, 2)
C(0, -2)
D(-3, 0)
Answer:
A
Step-by-step explanation:
The x-intercepts are the roots of a parabola. Specifically, when a parabola is in the form [tex]f(x)=(x-h)(x-k)[/tex], where h and k are real numbers, the roots are [tex](h, 0)[/tex] and [tex](k, 0)[/tex].
Our parabola has a plus, though. That's a problem, right?
No! [tex]x+2=x-(-2)[/tex], so there's no problem. So, our roots are [tex](3, 0)[/tex] and [tex](-2, 0)[/tex].

How do I solve the equation if x = 2 and y = 4?
Answer:
18
Step-by-step explanation:
[tex] \\ \sf16 {x}^{0} + 2 {x}^{2} \times {y}^{ - 1} [/tex]
Now putting the values of x and y.
[tex] \\ \sf16 \times {2}^{0} + 2 \times {2}^{2} \times {4}^{ - 1} [/tex]
[tex] \\ \sf = 16 \times 1 + 2 \times 4 \times \frac{1}{ {4}}[/tex]

Please help me with this answer ASAP
Step-by-step explanation:
first let's bring the equation into "normal" form :
x - 2y = 2
-2y = 2 - x
2y = x - 2
y = x/2 - 1
so, the slope of this line is 1/2 (the factor of x - that is always the case in all lines).
a parallel line must have the same slope, of course.
so, its equation is
y = x/2 + b
now, b will be different to the -1 of the original equation, or the lines are identical.
it is the point of interception of the line through the y-axis (x = 0).
we get this by using the coordinates of the given point (4, -3).
so,
-3 = 4/2 + b = 2 + b
b = -5
therefore, the formula for the parallel line is
y = x/2 - 5

Answer:
12 and (-12)
Step-by-step explanation:
Solve for x.
x^2= 144
square root both sides and get,
x= 12
and
x= (-12)
remember to put your negative and 12 into parenthesis because you are multiplying the negative as well.
Answer:
x = 12
x = -12
Step-by-step explanation:
Step 1: Take the square root of both sides.
[tex]\sqrt{x^2} =[/tex] ± [tex]\sqrt{144}[/tex] [tex]x =[/tex] ± [tex]\sqrt{144}[/tex] [tex]x = 12[/tex] or [tex]x = -12[/tex]Therefore, x = 12 and x = -12 are the answers.

Liam knows the key to making creamy risotto, a rice dish, is to add the liquid to the rice gradually. He adds 5 ladles of chicken broth to his rice before adding seasoning, and he continues to add 2 ladles of broth each minute afterwards.Write an equation that shows the relationship between the number of minutes since Liam added the seasoning, x, and the total number of ladles of broth he has added, y.
The equation that shows the relationship between the number of minutes and total number of ladles of broth is y = 2x + 5
Let x represent the number of minutes and y represent the total number of ladies.
Since he adds 2 ladles of broth each minute and he has 5 ladies initially, hence:
y = 2x + 5
The equation that shows the relationship between the number of minutes and total number of ladles of broth is y = 2x + 5
