Answer:

360 miles

Step-by-step explanation:

The unit rate here is (240 miles) / (2 hours), or 120 mph.

In 3 hours the vehicle travels (120 mph)(3 hrs) = 360 miles

Answer:

360

Step-by-step explanation:

240/2 =120 So, you want to add 120 to 240 to get 360.

Answer:7.8

Step-by-step explanation:

Answer:

D) b/a

From the given figure, O = (0, 0) and A = (a, b)

Slope of OA = (y2 - y1) / (x2 - x1)

Here x1 = 0, y1 = 0, x2 = a and y2 = b.

Slope of OA = (b - 0)/(a - 0)

Slope of OA = b/a

Answer: D) b/a

Actually Welcome to the Concept of the linear equation in two variables.

So we have to form two equations to solve this.

Let the number of children be 'x' and number of adults be 'y'.

hence, we get as,

x+y = 630 ..... (1)

and also, to their total cost spending, we get as,

1.5x + 2.25y = 1170 ...... (2)

solving (1) and (2) we get as,

Number of children were = 330

and Number of Adults were = 300

Answer:

9

Step-by-step explanation:

(70-16)/6=9

/ = division

Price before decrease = x

If price before decrease is 100, then price after decrease = 100- 12 = 88

100:88 = x:600

100/88=x/600

100/88 ×600 = x

681.82 =x

Price before decrease =681.82

Answer:

-1/2

Step-by-step explanation:

Answer:

y = -1/2x + 1

Step-by-step explanation:

(0,1) and (2,0)

Slope:

m=(y2-y1)/(x2-x1)

m=(0-1)/(2-0)

m=(-1)/2

m= -1/2

Slope-intercept:

y - y1 = m(x - x1)

y - 1 = -1/2(x - 0)

y - 1 = -1/2x

y = -1/2x + 1

Answer:

Step-by-step explanation:

y=mx+b

m=(y2-y1)/(x2-x1), we have points (-3,6) and (9,-5)

m=(-5-6)/(9-(-3))

m=-11/12 so now we have

y=-11x/12+b, using point (9,-5) we can solve for b

-5=-11(9)/12+b

-5=-99/12+b

b=39/12

y=(-11x+39)/12

That is the line, m=-11/12 and b=39/12 or as a decimal b=3.25. You had b so not sure what the problem is. Though the question in the picture asks what the line is. The line is

y=-11x/12+13/4 so maybe they want the entire function instead of entering what b is.

Answer:

Solve systems of equations by graphing

A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.

Example

[tex]\left \{ {{y=2x+2} \atop {y=x-1}} \right.[/tex]

Graph the equations in a coordinate plane

The two lines intersect in (-3, -4) which is the solution to this system of equations.

Answer:

The number of terms in the sequence is 9

Step-by-step explanation:

We want to get the number of terms

Mathematically, we have the formula for the sum of terms in an arithmetic sequence as

[tex]sn = \frac{n}{2} (a + 1)[/tex]

a represents the first terms, and i represent the last term

[tex]423 = \frac{n}{2} (15 + 79) \\ \\ 423 \times 2 = 94(n) \\ \\ 94n = 846 \\ \\ n = \frac{846}{94} \\ \\ n = 9[/tex]

Answer:

C) y = x-2

Step-by-step explanation:

0-2= -2

2-2= 0

3-2= 1

4-2= 2

And all of that checks out because the values I just got for y are the same as the table

Answer:

Triangle y = 7

Triangle x = -3

Slope = - 7/3

Step-by-step explanation:

Formula:

slope (or m) = (y2 - y1)/(x2 - x1)

Plug numbers into formula

m = 8 - 1 / 4 - 7

m = 7 / -3

Cannot be simplified further

Slope = - 7/3

The triangle before y is asking for the difference, meaning what number do you get after taking y2 (8 in this problem) and subtracting y1 (1 in this problem) from it.

8 - 1 = 7 which forms the numerator for our slope

The same goes for the triangle before x. Find the difference

x2 - x1 = 4 - 7 = -3. This forms the denominator of our slope

Answer: The area of the plate is 81.67 in^2

Step-by-step explanation:

If we have a circle of radius R, the area of this circle can be computed as:

A = pi*R^2

where pi = 3.14

And the circumference is:

C = 2*pi*R

and we know that this is equal to 32 in, then:

32in = 2*pi*R

Now we can isolate R, and we get:

32in/(2*pi) = R

32in/(2*3.14) = R = 5.1 in

Then the area of the plate is:

A = 3.14*(5.1in)^2 = 81.67 in^2
