Answer:
y = - 2
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through.
The points (2, - 2) and (0, - 2) have the same y- coordinate and therefore lie on a horizontal line with equation
y = - 2
Answer:
$6
Step-by-step explanation:
We have: The cost of a taxi ride is represented by the function c(m)=2m+4
Plug 1 mile into "m" of the function c(m)=2m+4
So, we have c (1) = 2 ˣ 1 + 4 = 6
Thus, The cost per mile of the cab is $6.

2 * 3 = 6
x * x = x^2
6x^2
third box: 2x * 6
2 * 6 = 12
12x
answer: 8x^3 + 6x^2 + 12x
<h3>
3) (tp + 5)(4p - 6)</h3>
top left box: tp * 4p
p * p = p^2
4t
top right box: tp * - 6
-6tp
bottom left box: 5 * 4p
5 * 4 = 20
20p
bottom right box: 5 * - 6
5 * -6 = -11
-11
answer: 4tp^2 - 6tp + 20p - 11
<h3>
4) (4a - 8)(8a - 1)</h3>
top left box: 4a * 8a
4 * 8 = 32
a * a = a^2
32a^2
top right box: 4a * -1
4 * -1 = -4
-4a
bottom left box: -8 * 8a
-8 * 8 = -64
-64a
bottom right box: -8 * - 1
-8 * - 1 = 8
8
32a^2 - 4a - 64a + 8
<em>combine like terms</em>
32a^2 - 68a + 8 = answer
Answer:
Step-by-step explanation:
You can make 1.4 as a fraction, and it will be the same but in a different form.
So, to make a decimal by a fraction, you make 1.4 into a whole number. 1.4 will be 14.
Now, the denominator will be 10.
So, when you simplify , which is
