What is the value of _a_ in the equation below?
2a + 3 = 4a + 5
Answers
Step-by-step explanation:
hope it is helpful to you
Step-by-step
Simplifying 2a + 3 = 4a + 5
Reorder the terms: 3 + 2a = 4a + 5
Reorder the terms: 3 + 2a = 5 + 4a
Solving 3 + 2a = 5 + 4a
Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right.
Add '-4a' to each side of the equation. 3 + 2a + -4a = 5 + 4a + -4a
Combine like terms: 2a + -4a = -2a 3 + -2a = 5 + 4a + -4a Combine like terms: 4a + -4a = 0 3 + -2a = 5 + 0 3 + -2a = 5 Add '-3' to each side of the equation. 3 + -3 + -2a = 5 + -3 Combine like terms: 3 + -3 = 0 0 + -2a = 5 + -3 -2a = 5 + -3 Combine like terms: 5 + -3 = 2 -2a = 2 Divide each side by '-2'. a = -1 Simplifying a = -1

The rectangular prism and rectangular pyramid below have the same volume. Determine the value of x, the length of the prism.
Answers
ANSWER
[tex]x[/tex]= 9 [tex]in[/tex]
EXPLANATION
The volume of a rectangular prism is given by the formula,
[tex]V[/tex]= [tex]l[/tex] x [tex]b[/tex] x [tex]h[/tex]
We substitute the dimensions to obtain,
[tex]V[/tex]= 6 x 3 x 12 [tex]in^{3}[/tex]
The volume of the rectangular pyramid is,
[tex]V[/tex]= [tex]\frac{1}{3}[/tex] x 6 x 12 x [tex]x[/tex] [tex]in^{3}[/tex]
Equating the two values gives,
[tex]\frac{1}{3}[/tex] x 6 x 12 x [tex]x[/tex] = 6 x 3 x 12
We divide through by 6×12 to get,
[tex]\frac{x}{3}[/tex] = 3
We solve for x to obtain,
[tex]x[/tex] = 3 x 3
[tex]x[/tex] = 9 [tex]in[/tex]

You are shooting baskets in gym class. You are standing about 5 ft away from the basket and the hoop is at a standard height of 10 ft. The graph of y_1 = −0.4x^2 + 10 represents this scenario. After making 10 baskets at this spot your gym teacher tells you to move to a new spot. The graph of y2 = −0.15x^2 + 10 represents your shots after the move.
Describe your new location in terms of your original location. Use the equation to explain.
A. The equations show that the absolute value of a decreased, which indicates that I moved further away from the basket.
B. The equations show that the absolute value of a increased, which indicates that I moved further away from the basket.
C. The equations show that the absolute value of a decreased, which indicates that I moved closer to the basket.
D. The equations show that the absolute value of a increased, which indicates that I moved closer to the basket.

Will the graph of y = (7.25x)^2 be stretched or compressed horizontally or vertically when compared to the parent function y = x^2?
A. Because |b| < 1, the graph will be compressed vertically.
B. Because |b| < 1, the graph will be compressed horizontally.
C. Because |b| > 1, the graph will be compressed vertically.
D. Because |b| > 1, the graph will be compressed horizontally.
Answers
The correct statement is,
⇒ Because |b| > 1, the graph will be compressed horizontally.
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).
Given that;
Parent function is,
⇒ y = x²
And, Function is,
⇒ y = (7.25x)²
Now, The value of b = 7.25 is greater than 1.
Hence, the graph of y = (7.25x)² be compressed horizontally.
Thus, The correct statement is,
⇒ Because |b| > 1, the graph will be compressed horizontally.

Step-by-step explanation:
Skills needed: Triangle Angle Measures, Solving a One-Variable Equation
1) To get the answer, you need to know that all the angles inside a triangle add up to 180 degrees. This is very important in the future as well.
2) So to find x, we can make the equation: x + 30 + 45 = 180
3) You can combine like terms:
30 and 45 can be combined --> 30 + 45 = 75
4) Based on step 3, you can get: x + 75 = 180
Subtract 75 from both sides, and you will get: x = 105

Answer:
Yes. When looking at the word "TAKE" you can see that there are four letters. The probability of selecting the letter 'a' would be 1/4. The probability of selecting the letter 'k' would also be 1/4. This is because they are 1 out of 4 of the letters making up the word "TAKE". So, the outcomes are equally likely to occur.

B. Mean: 15 Median: 17 Mode: 18 Range: 7
C. Mean: 14 Median: 18 Mode: 15 Range: 8
D. Mean: 16 Median: 15 Mode: 9 Range: 18
Answers
To find the mean, you add, 9+10+15+18+18 and you get 70. You then divide them by 5 because that’s how many numbers you have and you get 14.
To find median, you rearrange the numbers from largest to smallest, (9,10,15,18,18) and the number in the middle is 15. That is your median.
The mode is 18 because you have more than one of it.
And the range, 18-9=9. You subtract the smallest number from the biggest and you get 9.
