Answers
Answer: x=4, y=32
Step-by-step explanation:
y=8x
4x+y=48
Plug in 8x for y in the equation
4x+8x = 48
Add like terms
12x= 48
Divide both side by 12
12x/12=48/12
x= 4
Then plug 4 back into the original equation in place of x
4(4)+y=48
16+y=48
Minus 16 from both sides
y= 48-16
y= 32
Answer: (4,32)
Answer: x = 4
Step-by-step explanation: 48 divided by 12 = 4
4 x 4 = 16
Y = 8x
8 x 4 = 32
32 + 16 = 48

For number one, you are looking for how many multiplication equations can equal the number given. For example,
C) 12: 1, 12, 6, 2, 3, 4,
For number 2, composite numbers are numbers that are products of two smaller numbers.
For example, 30=15x2, so it is composite. Try dividing the numbers to see if they are composite.
For number 3,

Sum is addition and there is only one expression of the three that has addition. So sum goes with 5/6+8b.
Quotient is division or fraction so 5/6 is the expression to go with quotient.
Product is times so 8b is the expression that goes with that because 8b means 8 times b.

What is the cost of 2.6 pounds of cheese at $6.75 per pound
WORTH A LOT OF POINTS BRAINLIEST IF CORRECT
Answers
Answer:
$17.55
Step-by-step explanation:
simply multiply the price by the amount of the product so: 2.6*6.75= 17.55
1 pound of cheese = $6.75
We need to find the price of 2.6 pounds of cheese and we can do this by multiplying both sides of the equation above by 2.6:
1 pound of cheese = $6.75
1 x 2.6 pounds of cheese = $6.75 x 2.6
2.6 pounds of cheese is $17.55

A parabola with no real zeros, a negative leading coefficient, and an odd y-intercept.
pls help!
Answers
Answer:
Step-by-step explanation:
A parabolic graph with no real zeros never touches or crosses the x-axis.
If the leading coefficient is negative, that tells us that the parabola opens down (and, in this case, that the entire graph is below the x-axis, because there are no real zeros.
If the y-intercept is odd, then the constant term, c, in ax^2 + bx + c, must be a negative, odd integer.
Suppose we say that the vertex of a particular parabola that is described by the above is (-2, -1) and that the y-intercept is -3. (Note: this is strictly an example.) Then the vertex equation of this parabola is obtained from the general vertex equation of a parabola,
y = a(x - h)^2 + k. Here h = -2 and k = -1, and so the particular parabola is
y = -a(x + 2)^2 - 1, where a is a constant and -a is negative.
In general form, this would be y = -a(x^2 + 4x + 4) - 1, or
y = -ax^2 - 4ax - 4a -1
and the constant terem (-4a -1) must be an odd negative integer
This is only one of an infinite number of possible equations for the parabola described above.

How to write a linear equation?A linear equation for the given case can be written by assuming any variable as the unknown quantity. Then, as per the given data the required operations are done and it is equated to some value.
Suppose the number be x.
Then, the following equation can be written for information given as,
1/4(x - 3.2) = 1.8
It can be solved as,
x - 3.2 = 1.8 × 4
⇒ x = 7.2 + 3.2 = 10.4
It can be written in mixed form as below,
10.4 = 10 + 4/10
