Answer 1

Answer:

2230

Step-by-step explanation:

subtract 48 from 2212 which will be 2164 and then add 66 to 2164 and then you get 2230

Answer 2

Answer:

[tex]\huge\boxed{2329 \ \text{pounds}}[/tex]

Step-by-step explanation:

In order to solve this equation, let's see what we already know.

We know two points on the graph which we can use to find the slope

That's about it.

However, this can come useful to find the slope between the two points, which is the slope for the entire graph (since this is linear). The slope between two points is usually defined as [tex]\frac{\Delta y}{\Delta x}[/tex] (change in y / change in x). Our two points are (18, 2017) and (48, 2212).

The change in y between our two points is [tex]2212-2017 = 195[/tex], and the change in x is [tex]48 - 18 = 30[/tex]. Our slope will then be [tex]\frac{195}{30}[/tex], which comes out to be approximately 6.5. Therefore, our slope is 6.5.

Now that we know the slope, we can substitute inside our equation in slope intercept form.

[tex]y = 6.5x+b[/tex]

We have yet to find b, the y-intercept (how much the plane itself weighs). To find b, we can substitute a point on the graph into the equation and solve for b. We know that the point (18, 2017) is on the graph so let's use that.

[tex]2017 = 6.5 \cdot18 + b[/tex] [tex]2017 = 117 + b[/tex] [tex]1900= b[/tex]

Now that we know our y-intercept is 1900, we can create our equation by using the slope and the y-intercept.

[tex]y=6.5x+1900[/tex]

Finally, to find the weight of the plane with 66 pounds of fuel, we can substitute 66 inside this equation as x.

[tex]y = 6.5 \cdot66+ 1900[/tex] [tex]y = 429+1900[/tex] [tex]y=2329[/tex]

So the plane weighed 2329 pounds with 66 gallons of fuel.

Hope this helped!

Write the equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x

Answers

Answer:

[tex]\displaystyle y=-\frac{2}{3}x+3[/tex]

Step-by-step explanation:

We want to find the equation of the line that is parallel to:

[tex]\displaystyle y=-\frac{2}{3}x[/tex]

And passes through (-3,5).

First, we need to determine the slope of our new line.

Remember that parallel lines have the same slope.

Since the slope of our original line is -2/3, this means that the slope of our new line must also be -2/3.

Now, we can use the point-slope form given by:

[tex]y-y_1=m(x-x_1)[/tex]

We will let (-3, 5) be (x₁, y₁). By substitution:

[tex]\displaystyle y-(5)=-\frac{2}{3}(x-(-3))[/tex]

Simplify:

[tex]\displaystyle y-5=-\frac{2}{3}(x+3)[/tex]

Distribute:

[tex]\displaystyle y-5=-\frac{2}{3}x-2[/tex]

Add 5 to both sides. So, our equation is:

[tex]\displaystyle y=-\frac{2}{3}x+3[/tex]

Answer:

[tex]\displaystyle y = -\frac{2}{3}x + 3[/tex]

Step-by-step explanation:

5 = –⅔[–3] + b

[tex]\displaystyle 3 = b \\ \\ y = -\frac{2}{3}x + 3[/tex]

Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so –⅔ remains as is.

Answer:

you would move left once, then left again 6 times. so 7 times to the left.

Step-by-step explanation:

You're moving left because you're working with negative numbers, so -1 would be the first step, and then just move 6 times more to the left. When you work with positives you do the same but to the right.

Answers

Answer:

A, B & D

Step-by-step explanation:

Because if you subtract one of the constants from both sides then you should only have equal variables. In other words, both sides have to be identical in this situation.

33x-33= 33x + 25

33x = 33x + 58 No matter what you make x, the right will be 58 bigger than the right so there is no solution.

33x+33=33x+25

33x+8= 33x nope no solution

33x+25=33x+25

33x = 33x both sides identical so there is a solution

33x-25 = 33x +25

33x= 33x+50

The base angle of an isosceles triangle is always the complement of half the third angle. That angle's bisector is an altitude, so divides the isosceles triangle into two congruent right triangles.

A recipe requires 3 cups of flour to make 27 dinner rolls. How much flour is needed to make 9 rolls?Mandy runs 4 km in 18 min. She plans to run in a 15 km race. How long will it take her to complete the race?

Answers

Answer:

a)1 cup of flour

b)67.5 minutes

Step-by-step explanation:

a) A recipe requires 3 cups of flour to make 27 dinner rolls. How much flour is needed to make 9 rolls?

From the above question, we know that:

27 dinner rolls = 3 cups of flour

9 dinner rolls = x

Cross Multiply

27 rolls × x = 9 rolls × 3 cups

x = 9 rolls × 3 cups/27 rolls

x = 1 cup of flour

Hence, 1 cup of flour is needed to make 9 dinner rolls

b) Mandy runs 4 km in 18 min. She plans to run in a 15 km race. How long will it take her to complete the race?

From the above question:

4 km = 18 minutes

15km = x

Cross Multiply

4km × x = 15km × 18 minutes

x = 15km × 18minutes/4km

x = 67.5 minutes

Hence, in a 15km race , it would take her 67.5 minutes to complete her race.
