Which graph represents the equation y = --3x – 1?
Answers
Answer:
Step-by-step explanation:
The equation y = -3x - 1 represents a straight line with a slope of -3 and y-intercept of -1. The graph will be a line falling to the right and crossing the y-axis at -1.
Explanation:The question asks which graph represents the equation y = -3x - 1. This is a linear equation, where the coefficient of 'x', -3 here, gives us the slope of the line, and the constant, -1 here, gives us the y-intercept. A slope of -3 means for each step of 1 increase in x, the value of y decreases by 3. The y-intercept is the point where the line intersects with the y-axis, in this case at y = -1.
A graph representing this equation will be a straight line with a slope of -3 (indicating the line falls as we move along the positive x-axis) and will cut the y-axis at y = -1.

Answers
Answer: B
Step-by-step explanation: 6^2 = 36
36*4= 144
144-7= 137
Answer:
B. 137
Step-by-step explanation:
Assuming by 4x2 you meant 4[tex]x^{2}[/tex], you plug in the 6 into x.
After, you would square 6, giving you 36.
Then you multiply 36 by 4, getting 144
All that's left to do is subtract 7 from 144 and ending with 137.

Answer:
La respuesta es la C
Step-by-step explanation:

The required, tax would be $25,750 if the Tanners file jointly.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Assuming that the tax rate of 25% applies to their combined taxable income, here's how to calculate their taxes if they filed jointly:
Calculate their combined taxable income:
$75,000 + $28,000 = $103,000
Calculate their tax liability based on their combined taxable income: $103,000 x 0.25 = $25,750
Therefore, the answer is C. $25,750, if the Tanners file jointly.

What is the correct factorization of 5!?
Answers
Answer:
B) 5 x 4 x 3 x 2 x 1
Step-by-step explanation:
When you see a ! directly next to a number (such as 5!), it means that you are multiplying starting from that number, and stepping down each time:
5! = 5 * 4 * 3 * 2 * 1
For example, take factoral 10: 10!
10! = 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 3,628,800
In this case, you are multiplying 5!.
5! = 5 * 4 * 3 * 2 * 1 = (20) * (6) * 1 = 120
5! = 120

A gopher dug holes in opposite corners of a rectangle yard. If the yard is 7 meters by 6 meters how far will the gopher have run to get from one of its holes to the other. round if necessary to the nearest tenth. use the formula a square plus b square equals c square
Answers
Answer: 9.2 meters
Step-by-step explanation:
Hi, since the situation forms a 2 right triangles (see attachment) we have to apply the Pythagorean Theorem:
c^2 = a^2 + b^2
Where c is the hypotenuse (x) of each triangle (in this case the distance between the opposite corners) and a and b are the other sides.
Replacing with the values given:
c^2 = 6^2 + 7^2
c^2 = 36+49
c^2 = 85
c = √85
c = 9.2 meters
Feel free to ask for more if needed or if you did not understand something.
Final answer:
To find the distance the gopher needs to run between the holes in a rectangle yard, use the Pythagorean Theorem with the given sides (7 meters by 6 meters) to calculate the diagonal distance of approximately 9.2 meters.
Explanation:
A gopher dug holes in opposite corners of a rectangle yard. If the yard is 7 meters by 6 meters, how far will the gopher have run to get from one of its holes to the other, rounded if necessary to the nearest tenth? Use the formula a square plus b square equals c square.
Identify the two sides of the rectangle as a and b, where a = 7 meters and b = 6 meters.
Apply the Pythagorean Theorem: a² + b² = c². Substitute the values: 7² + 6² = c².
Calculate the distance: 7² + 6² = c² ➔ 49 + 36 = c² ➔ 85 = c² ➔ c ≈ √85 ≈ 9.2 meters. So, the gopher would need to run approximately 9.2 meters to move between the holes.

I NEED THE ANSWER ASAP PLEASE
Answers
Answer:
x<2.5
Step-by-step explanation:
-4x +5>-5
-4x>-5-5
-4x>-10
x<10/4(on multiplying (-)ve sign both the sides inequality changes)
x < 2.5
The inequality -4x + 5 > -5 simplifies to x < 2.5 after isolating the variable and dividing by -4, which also reverses the inequality sign.
Explanation:To solve the inequality -4x + 5 > -5, we first isolate the variable on one side:
Add or subtract constants from both sides of the inequality as needed.Divide or multiply both sides by the coefficient of the variable, taking care to reverse the inequality sign if you multiply or divide by a negative number.Let's solve the inequality step-by-step:
Add 5 to both sides to get -4x > -10.Divide both sides by -4, remembering to reverse the inequality sign, so x < 2.5.Therefore, the solution to the inequality is x < 2.5.

A. 45
B. 90
C. 90√2
D. 90√3
Answers
Answer: The correct answer is option C; 90√2
Step-by-step explanation: The line segments are labelled as base 1, base 2 and base 3 respectively. This we shall call point 1, point 2 and point 3. These three points form a right angle. Also we have been told that Marcus is on point 3 and Jean is on point 2. They are both 90 feet apart. Also Joel is on point 1 and he is 90 feet away from Jean. The unmeasured distance therefore is from point 1 to point 3, which is the distance from Joel to Marcus (or Marcus to Joel).
The distance from point 1 to point 3 is the hypotenuse of the right angled triangle derived. Using the Pythagoras' theorem, the distance from Joel to Marcus (or JM) is calculated as follows;
JM² = JC² + JL²
Where JM is the distance between Joel and Marcus (hypotenuse), JC is the distance from Jean to Marcus and JL is the distance from Jean to Joel.
JM² = 90² + 90²
JM² = 8100 + 8100
JM² = 16200
Add the square root sign to both sides of the equation
√JM = √16200
JM = √100*√81*√2
The right hand side of the equation can be further solved as
JM = 10*9*√2
JM = 90√2
Therefore the distance between Marcus and Joel is calculated as 90√2 feet
