What is the slope of the line?

Answers

Answer 1

Answer:

2/3

Step-by-step explanation:

Step 1

(1,2) (4,4)

First we are going to pick two point on the line.

Step 2

(y2-y1) / (x2-x1)

(4-2) / (4-1)

in the first set we label x as x1 and y as y1, then we do the same with the other set but with x turning into x2 and y turning into y2. We then plug them into the equation.

Step 3

(2)/(3)

2/3

Now we solve what is in the parentheses (4-2) is 2, and (4-1) is 3. We then take away the parentheses and have 2/3. keep 2/3 as a fraction, do not change it to a decimal.

Answer 2

The answer would be 2/3

2x+y=10

Step-by-step explanation:

plzz mark me brainliest as it need it to level up

Answer:
10=2x+y

Explanation:
Let x be equal to the first number.
Let y be equal to the second number.

The question tells us that 10 is equal to double the first number plus the second number.

We can translate this information into an equation by looking at key words and translating them into math.

Key words:
equal: =
double: *2
plus: +

Using this, we get the equation 10=2x+y.

An architect plans a courtyard with a length of 16.4 yards, then learns its width must change by −2.3 yards. What is its new width?

Answers

Answer:

The answer is 14.1

Step-by-step explanation:

16.4+-2.3=14.1

-2.3 isnt large enough to make 16.4 a negative.

The new width is 14.1 yards if the architect plans a courtyard with a width of 16.4 yards, then learns its length must change by -2.3 yards option (B) 16.4 + (-2.3) is correct.

What is a rectangle?

It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is given that:

An architect plans a courtyard with a width of 16.4 yards, then learns its length must change by -2.3 yards.

Let new width be x:

x = old width + (change in width)

Change in width = -2.3

x = 16.4 + (-2.3) = 14.1 yards

Thus, the new width is 14.1 yards if the architect plans a courtyard with a width of 16.4 yards, then learns its length must change by -2.3 yards option (B) 16.4 + (-2.3) is correct.

Han and Tyler are following a polenta recipe that uses 5 cups of water for every 2 cups of cornmeal.

1 * Han says, “I am using 3 cups of water. I will need 115 cups of cornmeal.”
2 * Tyler says, “I am using 3 cups of cornmeal. I will need 712 cups of water.”
Do you agree with either of them? Show your reasoning.

Answers

Answer:

Step-by-step explanation:

1. 5 cups of cornmeal=2 cups of water. Using 115 cups of cormeal would mean you need 287.5 cups of water, not 3.

3 is too little

2: If you use 5 cups of water for every 3 cups of cornmeal, for 3 cups of cornmeal you'd need like 6.5 cups of water, not that high of a number.

As the given reasoning 3 cups of water is very less than both the statements are not appropriate.

What is an expression?

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the given reasoning in the question,

1. 2 cups of water to 5 cups of cornmeal. Instead of 3, you would use 287.5 cups of water if you used 115 cups of cornmeal.

2. If you are using 5 cups of water for every 3 cups of cornmeal, you would need 6.5 cups of water, which is not a particularly high quantity.

On a coordinate grid, both point (3, 5) and point (−2, −4) are reflected across the y-axis. What are the coordinates of the reflected points?

(−3, 5) and (2, 4)
(−3, 5) and (2, −4)
(−3, −5) and (−2, −4)
(3, −5) and (−2, −4)

Answers

The answer is B. Since it is flipping over the why y axis the y coordinate stays the same so in 3,5 the 5 is the y coordinate so it stays the same and the x coordinate changes to the opposite. So since 3 is the x coordinate it would change from 3 to -3 so it would be -3,5. The same goes for the -2,-4. The -4 stays the same since it is the y coordinate and the x coordinate changes from -2 to 2 so it become 2,-4. So it is b

What is the best estimate of the sum of the fractions?

StartFraction 31 over 4 EndFraction + StartFraction 17 over 3 EndFraction + StartFraction 8 over 18 EndFraction

Answers

Answer:

Let's add the fractions first and then we can estimate the sum.

= 31/4 + 17/3 + 8/18

change to common denominators

= 279/36 + 204/36 + 16/36

add numerators only

= 499/36 or 13 31/36 or 13.86

ANSWER: (B) 13 is the best estimate of the answer. Normally we round up to 14 with a number like 13.86, but since that is not a choice, we can estimate 13 as the answer.

Answer:

Step-by-step explanation:

A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4°F. The submarine dives down 115 feet deeper, and the water temperature drops by 2 1/5 °F. What were the elevation and the water temperature after the submarine dove? Assume that sea level is at 0 feet of elevation.

Write an expression to represent the water temperature after the submarine’s final dive. Then simplify the expression to find the temperature.

Answers

Answer:

At the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F

Step-by-step explanation:

At 502.5 feet below the sea level temperature of the water is 63\frac{1}{4}°F

When submarine dives down 115 feet deeper, water temperature drops by 2\frac{1}{5}°F

Elevation after the submarine dove = -502.5 - 115 = -617.5 feet

This negative sign represents the elevation below the sea level.

And the temperature will be = 63\frac{1}{4}-2\frac{1}{5}

= \frac{253}{4}-\frac{11}{5}

= \frac{1265-44}{20}

= \frac{1221}{20}

= 61\frac{1}{20}°F

Therefore, at the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F

The required expression is y = 0.01x + 58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.

A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4°F.

What are functions?

It is the relationship between sets of values. e g y=f(x),

Here, assume that relation ship between temperature and sea level is linear. So the expression can be calculated as y = - 0.01x + 58.2.
Since at 115 feet deeper from 502.5 temperature-
total sea level; = 502.5+115
= 617.5
Put it in expression
y = -0.01 * 617.5 + 68.2
y = 61.25
y = 61 1/4 °F

Thus, the required expression is y = 0.01x + 58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.
