B. 9x2 – 2x + 5
c. 9x2 + 2x + 4-1
D. 9x2 – 5x + 7x + 5

Answers

Answer 1

Answer:

option B. 9x² – 2x + 5x

Micah is shopping for work shirts. The short-sleeve shirts cost $18 each and the long-sleeve shirts cost $24 each. He wants to buy 2 more short-sleeve shirts than long-sleeve shirts, and he is willing to spend no more than $120 total. How many long-sleeve shirts can he buy?

Answers

Answer:

2

Step-by-step explanation:

18 + 18 = 36

36 + 24 = 60

60 + 18 = 78

78 + 24 = 102

102 + 18 = 120

There are two total long-sleeve shirts and four total short-sleeve shirts.

How do you write an equation from a statement?

Statements to Equations Conversion and the Other Way Around

First, carefully read the sentence.Step 2: A value that is unknown or has to be located is designated as a variable, such as x, y, a, or b.Step 4: The expressions are created in accordance with the guidelines provided in the questions.

Cost of 1 short-sleeve shirt: $18.

Cost of one long-sleeve shirt: $24.

Purchase 2 more short-sleeve shirts than long-sleeve shirts, and the total cost will be $120.

Assuming 2 long sleeves and 4 short sleeves, we get 120, or 2*24 + 4*18 = 120.

He purchased two long-sleeve shirts and four short-sleeve shirts after the condition was met.

Additionally, the requirement of 2 more short-sleeve shirts than long-sleeve shirts is met.

Which graph represents the function f(x) = –|x + 3|?

Answers

Answer:

Step-by-step explanation:

f(x) = –|x + 3| is a case of the absolute value function

f(x) = -|x - {a}| + c, where (a, c) is the vertex.  Comparing them, we see that

the value of a must be -3 and that of c must be 0.

Thus, the vertex of the graph is at (-3, 0), and the graph opens up; it looks like a "v" shape.

The difference of six times a number and seven results in 35.

Identify the steps necessary to solve the equation.

Answers

Answer:

Let the number be x

According to the question,

6x -7 = 35

=> 6x = 35 + 7

=> x = 42/6

=> x = 7

The solution to the equation is x = 7.

We have,

Let's assume the unknown number is represented by the variable 'x'.

- Translate the given information into an equation:

6x - 7 = 35.

- To isolate the variable 'x', start by adding 7 to both sides of the equation:

6x - 7 + 7 = 35 + 7.

- Simplify:

6x = 42.

- Next, divide both sides of the equation by 6 to solve for 'x':

(6x)/6 = 42/6.

x = 7

Therefore,

The solution to the equation is x = 7.

Answer: The slope is 3/2  or 1.5

Step-by-step explanation:

The line is going through the origin meaning that the slope will be the coordinate of one of the points divided by its y coordinate.  

One point that can be found on the line is  (2,3)

Divide the y coordinate by the x coordinate to find the slope.

The y coordinate is 3 and the x coordinate is 2.

3/2 = 1.5

The slope is 3/2  or 1.5.

Andre ran 2 kilometers in 15 minutes, and Jada ran 3 kilometers in 20 minutes. Both ran at a constant speed. Did they run at the same speed?

Answers

Answer:

speed of Jada = 6km per hour which is not equal to

speed of Andre = 8km per hour

They did not run at same speed

Step-by-step explanation:

formula of speed = distance covered/ time taken

For Andre

Distance = 2 KM

time = 15 mins

60 mins = 1 hour

15 mins = 1/60 * 15 hour = 0.25 hours

thus,

speed = 2km/0.25 hour = 8 km per hour

Similarly for Jada

Distance = 3 KM

time = 20 mins

60 mins = 1 hour

20 mins = 1/60 * 20 hour = 1/3 hours

thus,

speed = 2km/(1/3)hour = 6  km per hour

Now we have

speed of Jada = 6km per hour which is not equal to

speed of Andre = 8km per hour

Answers

Answer:

im pretty sure the answer is ∠e and ∠i; ∠f and ∠g

but if not im so sorry :(

Answer:

The third answer

Step-by-step explanation:

Each angle on both triangles has a set of lines, either one, two, or three. These lines are used to show congruency over a number of lines or angles. So one angle will correlate with whatever other angles have that same number of lines. For example, e and g both have two lines, this means they are corresponding and congruent.

Answers

Answer:

y = - [tex]\frac{1}{3}[/tex] x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m= [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 6, 7) and (x₂, y₂ ) = (- 3, 6)

m = [tex]\frac{6-7}{-3+6}[/tex] = [tex]\frac{-1}{3}[/tex] = - [tex]\frac{1}{3}[/tex] , thus

y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 3, 6 ), then

6 = 1 + c ⇒ c = 6 - 1 = 5

y = - [tex]\frac{1}{3}[/tex] x + 5 ← equation of line
