hey you can help me help pls
Answer:
[tex]2\frac{4}{5}[/tex]
Step-by-step explanation:
Rewriting our equation with parts separated
[tex]=9+\frac{1}{5} -6-\frac{2}{5}[/tex]
Solving the whole number parts
[tex]9-6=3[/tex]
Solving the fraction parts
[tex]\frac{1}{5} -\frac{2}{5} =-\frac{1}{5}[/tex]
Combining the whole and fraction parts
[tex]3-\frac{1}{5}=2\frac{4}{5}[/tex]
A motorboat moves across a lake at a constant speed. When it begins, it is 55 km from the shore. After 12 minutes, it is 19 km from the shore. Which function describes the motorboat's distance from the shore?
A. y = –12x + 19
B. y = –3x + 55
C. y = 3x + 55
D. y = –12x + 55
Answer:
y= _3x+55
Step-by-step explanation:
we conqet two points
(0,55) (12,19)
55=B subsiquent two points into the equation
19=a,12+55
a=-3
b=55
so we choose B
Answer:-3x=55

How much more is 8 3/4 than 1 1/4?
Answer:
[tex]7 \frac{1}{2} [/tex]
Step-by-step explanation:
[tex]8 \frac{3}{4} - 1 \frac{1}{4} = \frac{35}{4 } - \frac{5}{4} \\ = \frac{30}{4} \\ = 7 \frac{2}{4} \\ = 7 \frac{1}{2} [/tex]

For each table, write the equation that represents the price per ticket.
Answer:
Multiply.
Step-by-step explanation:
2 * 15 = 30
5 * 37.50 = 187.5
6 * 45 = 270
8 * 60 = 480
480 + 270 = 750
187.5 + 30 = 217.5.

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.

Step-by-step explanation:
1. 223 is q added to 158
223 = q + 158
2. d divided by 34 is the same as d
d / 34 = d
3. 299/b = t
4. p = 204 × p
5. 103 is equal to m added to 343
103 = m + 343

The price of an item has been reduced by 35%. The original price was $60. What is the price of the item now
Answer:
Step-by-step explanation:
$60=100%
A 35% reduction is the same as multiplying by 0.65(1-0.35).
$60*0.65=$39

Step-by-step explanation:
Last week, Byron bought 5 containers of yogurt and spent $12.88 on other groceries.
This week Cassandra bought 3 containers of the same yogurt and spent $11.50 on other
groceries. How much more money did Byron spend than Cassadra.
1. Let c represent the cost of one container of yogurt. Write
expressions to represent the amount spent by Byron and the
amount spent by Cassandra.
2. Write an expression to represent the difference by subtracting theamount that Cassandra spent from the amount that Byron spent.
Then complete the steps to simplify the expression
3. What expression represents how much more money Byron spent
than Cassandra?
Will Mark Brainlest
Answer: 5c$12.88 - 3c$11.50=C
Step-by step explanation:
Byron=5c + $12.88
Cassandra=3c + $11.50
So then, 5c$12.88 - 3c$11.50=C

Answer:
We are given that:
variables x and y vary directly, this means that:
y = kx where k is the constant of proportionality
Now, we are also given that:
y = 45 at x = 40.
We will use these values and substitute in the above relation to get k as follows:
y = kx
45 = 40k
k = 45/40 = 9/8 = 1.125
Based on the above calculations, the equation that relates x and y is:
y = 1.125x
