Answer:

t = -14

Step-by-step explanation:×

I did 4+3 which equals 7.

Now I know I need t/-2 to equal 7.

Next, I did 7×2 which equals 14.

When you divide 2 negative numbers you get a positive number.

So -14 ÷ -2 = 7

So t = -14

t= -14 this is the answer I hope this help

The following linear equation represents the line of best fit for the following scatter plot

y=0.15x-1.5

Use the equation to answer the following questions. Predict the number of hits a person would have to do to get 30 home runs.

A) 3
B) 210
C) 190
D) 6

Answers

Answer:

210 hits

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

y = home runs

x = hits

[Best Line of Fit] y = 0.15x - 1.5

We can use this to predict the average of the scatter plot.

home runs = y = 30

Step 2: Solve for x hits

Substitute [BLF]:                     30 = 0.15x - 1.5Add 1.5 to both sides:            31.5 = 0.15xDivide 0.15 on both sides:     210 = xRewrite:                                   x = 210

Remember that this is a prediction. According to the best line of fit, we would need 210 hits to get 30 home runs.

Answer:

Dish A has a greater rate of change

Step-by-step explanation:

For this question, the information is given in two different forms, in words and a graph, so you need to understand what everything represents. For dish A the starting number, 5, is the initial value, and the amount it grows every day, 2, is the rate of change. For dish B the y-intercept, 5, is the initial value, and the slope, 0, is the rate of change. From this, you can see that both the initial values are the same, which means both answers on the right are incorrect. Also since 2 is greater than 0 the bottom left answer must be incorrect. This only leaves the top left answer.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expression is,

⇒ (x¹⁴) (x⁻²)³ = xⁿ

So, Solve the expression by rule of exponent for the value of n,

⇒ (x¹⁴) (x⁻²)³ = xⁿ

⇒ (x¹⁴) (x⁻⁶) = xⁿ

⇒ x ¹⁴ ⁺ ⁻⁶ = xⁿ

⇒ x ¹⁴⁻⁶ = xⁿ

⇒ x⁸ = xⁿ

By comparing, we get;

⇒ n = 8

-2 pretty sure hope this helps
Answer: -2.

Here’s how you solve questions like these:

First of all, you have to learn the rule on the number line.

if it’s an addition problem, go forward.

if it’s a subtraction problem, go backwards.

if the number is positive, turn to the right.

if the number is negative, turn to the left.

So pretend you’re in between a number line that goes from -10 to 10, or on 0.

< -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 >

Take the first number and look at the rule. Since 2 is positive, you start at that number and face to the right.

< -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 >
>
Next, you take the symbol in between the two numbers. Since it’s the minus sign, or a subtraction problem, you have to get ready to walk backwards But before you do that, check the last number. Since 4 is positive, you still have to face to the right and move 4 spaces backwards.

< -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 >
< < < <

If this is confusing, I’ll demonstrate it in the comments again.
