8a -1+0.5b
Replace a nd b with the given values:
8(1/4) -1 + 0.5(10)
8 x 1/4 = 2
0.5 x 10 = 5
Now you have:
2 -1 + 5
2-1 = 1 +5 = 6
Answer is 6
Answer:
6
Step-by-step explanation:
Substitute the value of the variable into the expression and simplify.

A parabola with no real zeros, a negative leading coefficient, and an odd y-intercept.
pls help!
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.

approximate the square root to the nearest integer
-√18
Answer:
-4
Step-by-step explanation:
4² is 16, 5² is 25, and 18 is closest to 16. The nearest integer would be 4, or rather -4 in this case.
Explain the relationship between a strategy, such as number sense, and a written method , such as partial products or area models , for multiplying decimal number's.
Answer:
Hello
Step-by-step explanation:
You can take away the decimals
for example 0.33 x 0.7
do 33 x 7
which is 231
the 0.33 has 2 decimal spaces because there are 2 digits after the point
0.7 has 1 decimal place because there is 1 digit after the point.
so in total, there is 3 decimal
because you do 2 + 1
3
from the left, you count backwards and add the decimal point
the final answer should be 0.231
hope it helped

(help asap!) What is the value of the function at x = 2?
Enter your answer in the box.
Answer:
f(2) = -3
Step-by-step explanation:
Given the graph of a negative-sloped function:
In order to determine the value of a function given that x = 2, simply locate the x-coordinate of 2 in the graph, and find its corresponding y-coodinate. Doing so will provide you the corresponding output value of y = -3. Therefore, the value of the function at x = 2 is f(x) = -3, or f(2) = -3.

A. Kim pays $90 for every block of 5 dance classes. What rate can you write to represent this block of classes
Answer:
more info pls
Step-by-step explanation:
The rate of the block of glasses is, $18.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Kim pays $90 for every block of 5 dance classes.
Here, Kim pays $90 for every block of 5 dance classes.
Hence, The rate of the block of glasses is,
⇒ $90 / 5
⇒ $18
