Marissa is 7 years older than Mark. The sum of their ages is 59. How old are Marissa and Mark?
(A) First write an equation you can use to answer this question. Use x as your variable.
The equation is __________
Answer: Mark is ___________
and Marissa is ________

Answers

mark is 26=x and marissa id 33

if you take 59 take away 7 you get 52

then you wil devide 52 and get 26

you will use the 7 you took out earlier and add it to one of the 26 which will give you mark(26=x) and marissas(33) age .

A Speedy River barge bound for New Orleans leaves Baton Rouge, Louisiana, at 9:00 A.M. And travels at a speed of 10 miles per hour. A Rail Transport freight train also bound for New Orleans leaves Baton Rouge at 1:30 P.M. The same day. The train travels at 25 miles per hour, and the river barge travels at 10 miles per hour. Both the barge and the train will travel 100 miles to reach New Orleans.

Answers

Answer:

Step-by-step explanation:

A rail transport freight train also bound for New Orleans leaves Baton Rouge at 1;30 PM on the same day. The train travels at 25 MPH and the river barge travels at 10 MPH. ... the barge leaves at 9:00 am so that would be at 9 hours past midnight. the train leaves at 1:30 pm so that would be at 13.5 hours past midnight.At 1.30 p.m. the barge has already traveled 4.5 X 10 = 45 miles.To catch up it will take the train 25-10 = 15 miles

Answers

Answer:

The maximum value that the function reaches is 0, which occurs at x = 6.

What is a Quadratic equation?

ax²+bx+c=0, with a not equal to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.

Since a blank grid is given, we can plot the graph of the quadratic function f(x) = x^2 - 5x - 24 using the given points:

X: 10 -8 6 4 2 4 6 8 10

f(x): -116 -12 0 -8 -20 -8 0 8 24

The graph of the quadratic function looks like a parabola opening upwards, with the vertex at the point (2, -20).

Based on the graph, we can make the following observations:

The function has a minimum value of -20, which occurs at x = 2.The function is symmetric about the vertical line that passes through the vertex (2, -20).The function intersects the x-axis at x = -3 and x = 8.The function intersects the y-axis at y = -24.

Therefore, the statement that is NOT a true description of this quadratic function is:

"The function has a maximum value of 24, which occurs at x = 10."

This statement is not true because the function has a minimum value of -20 at x = 2, but it never reaches a maximum value of 24. The maximum value that the function reaches is 0, which occurs at x = 6.

I don't really understand these Questions..Can you help me?

Answers

Answer:

Problem 1: y = 4x + 6

Problem 2: 48 soda bottles per minute

Step-by-step explanation:

Problem 1:

Equation of a line in slope-intercept form is given as y = mx + b.

Wee have to figure out the value of the slope (m) and the value of y-intercept (b). Them to write an equation that represents the line of the graph, we need to input the values of m and b into the equation, y = mx + b.

Thus,

m = hourly fee = $4

b = initial deposit = $6

Substitute m = 4 and b = 6 into y = mx + b

Equation would be:

y = 4x + 6

Problem 2:

What we are simply asked to do is to find the slope of the line, which is the number of soda bottles the machine will produce per minute

Using the two points (3, 144) and (8, 384),

Slope = ∆y/∆x = (384 - 144)/(8 - 3)

Slope = 240/5 = 48

Thus, the machine will make 48 bottles per minute

Which equation could represent a vertical asymptote of the graph of the function?
O x=0
O y = 0
Ox= -1
O y=-1

Answer:

X=-1

Step-by-step explanation:

The correct equation could represent a vertical asymptote of the graph of the function is,

⇒ x = -1

What is mean by Function?

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Now, According to the given table, we see that for x = -1, the function is not defined, that means that the rational function has a restriction there, and such restriction is shown as an asymptote in the graph of the function.

So, basically, we could say that the given rational function has one asymptote and it's at x = -1, which is a vertical asymptote, because all forms like x = k, are vertical lines, that is, they are parallel to the vertical axis.

Therefore, The correct equation could represent a vertical asymptote of the graph of the function is,

⇒ x = -1

Answers

Answer:

x = 35, y = 26.5

Step-by-step explanation:

x = 35 ( Alternate angles are congruent )

The sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

2y - 10 + 35 + 102 = 180, that is

2y + 127 = 180 ( subtract 127 from both sides )

2y = 53 ( divide both sides by 2 )

y = 26.5
