Answer:

[tex]y = \frac{3}{2} x -1[/tex]

Step-by-step explanation:

[tex]y = \frac{3}{2} x -1[/tex]

At x=2

[tex]y = \frac{3}{2} (2) -1\\y=2[/tex]

At x=4

[tex]y = \frac {3}{2} (4) -1 \\y = 5[/tex]

At x=6

[tex]y = \frac {3}{2} (6) -1 \\y = 8[/tex]

At x=8

[tex]y = \frac {3}{2} (8) -1 \\y = 11[/tex]

Answer:

Answer:

  ∠A = 39°

  ∠B = 69°

Step-by-step explanation:

We assume these are angles in a triangle, so their sum is 180°.

  A + B + C = 180

  (x+50) +(x +80) +72 = 180

  2x +202 = 180

  2x = -22

  x = -11

Then the angle measures are ...

  A = -11 +50 = 39

  B = -11 +80 = 69

Angles A and B are 39° and 69°, respectively.

Answer:

Square cross section (Red)

Step-by-step explanation:

If the pyramid is cut with a plane (green) parallel to the base, the intersection of the pyramid and the plane is a square cross section (red). If the pyramid is cut with a plane (green) passing through the top vertex and perpendicular to the base, the intersection of the pyramid and the plane is a triangular cross section (red)

Answer:

A

Step-by-step explanation:

We know that ∠[tex]ABE[/tex] ≅ ∠[tex]DBC[/tex] because they are vertical angles, so that's one pair of congruent angles. However, we can't compare ∠[tex]BAE[/tex] and ∠[tex]DCB[/tex] as they have different measures, so we'll have to find the measure of either ∠[tex]AEB[/tex] or ∠[tex]BDC[/tex]. Let's go with the former. Using the fact that the sum of the measures of the interior angles of a triangle is [tex]180[/tex]°, we know that [tex]m[/tex]∠[tex]AEB=180-(53+42)=180-95=85[/tex]°. Now, we know that ∠[tex]AEB[/tex] ≅ ∠[tex]DCB[/tex] because their measures are equal. That's another pair of congruent angles. Therefore, the angles are similar by [tex]AA[/tex]. Hope this helps!

x=6

1-A 2-A 3-B

[tex] - 104 \geqslant - 8b - 8 [/tex]

put -8 near -104

[tex] - 104 + 8 \geqslant - 8b[/tex]

[tex] - 96 \geqslant - 8b[/tex]

b will be alone.

[tex] \frac{ - 96}{ - 8} \geqslant \frac{ - 8b}{ - 8} [/tex]

Answer:

Geometric

Step-by-step explanation:

Answer:

Geometric, 81, 3

Step-by-step explanation:

A geometric sequence is defined as one that continues with multiplication.

We can tell that the sequence proceeds by multiplying 1/3.

a2 is 81 because it is the second term given in the sequence.

a5 is 3 because it equals a4 *1/3, which is 9*1/3 which is 3

Answer:

FG - it is midline. FG = 5.

Explanation:

A midline in a triangle is a line segment connecting the midpoints of two sides.

A midline is half the length of the side to which it is parallel.

[tex]\dfrac{CE}{FG} =2\\\\ \dfrac{9x-26}{7x-23} =2\\\\9x-26=2(7x-23)\\9x-26=14x-46\\14x-9x=46-26\\5x=20\\x=4[/tex]

CE = 9 · 4 - 26 = 10

FG = 10/2 = 5

Answer: Number of children = 280 , Number of adults = 460.

Number of students = 360

Step-by-step explanation:

Let x= Number of children, y = number of adults.

Number of students = y-100

Given: At a local fair, the admission fees are $1.50 for children, $3 for college students, and $5 for adults.

1.50 x + 3 (y-100) + 5 y =3800   (i)

x+y-100+y= 1300 (ii)

From (iii)

1.50x + 3y -300+5y = 3800

⇒ 1.50x + 8y = 4100              (iii)

From (ii)

x+2y= 1200       (*)

⇒ 4x + 8y = 4800    (iv)      [multiply 4 on both sides]

Eliminate (iii) from (iv) , we get

2.5x = 700

⇒ x= 280 [ Divide both sides by 2.5]

Put x= 280 in (*), we get

280+ 2 y= 1200

⇒ 2 y= 920

⇒ y = 460

Hence, Number of children = 280 , Number of adults = 460.

Number of students = 460-100 = 360

Answer:

$53.20

Step-by-step explanation:

First, you need to find 24% of $70.

Change the percent to a decimal.

24% to .24.

Multiply that times 70.

.24 x 70 = 16.8

This will be the amount of money taken off the original price, so you will subtract it from the $70.

70 - 16.8 = 53.2

Therefore, the retail price is $53.20

Answer: $24.19

Step-by-step explanation:

From the question, we are informed that Mai bought gas for her car which cost $2.95 per gallon and that she bought 8.2 gallons.

The total cost for Mai's gas will be:

= $2.95 × 8.2

= $24.19

Answer:

Step-by-step explanation:

set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function!

Answer:

No

Step-by-step explanation:

What makes a function a function is that it only has one input for every output. So in other words the x can't have two y values. But on a graph you can just do the vertical line test to see if the line intersects the vertical line more than once for any x value, it fails. So if we use the vertical line test we can see that for the x value of 2 is intersected by the line more than once, so this isn't a function.

Answer:

18

Step-by-step explanation:

the ratio of blue eyed students to non-blue eyed students is 7 to 12,

Total ratio = 7+12=19

Total student= 50 students

Ratio of blue eyes student= 7/19 ×50

=18.4

Hence, there are approximately 18 students with blue eyes.

Answer: 60

Step-by-step explanation:

You do 4*12 and 4*3, 4*12=48, 4*3=12, Next you do 48+12 and you get 60

Answer: 4(12 + 3) = 48 + 12 = 60

Step-by-step explanation: We will use the distributive property to evaluate the expression, 4(12 + 3)

Simply do this by multiplying the number outside of the parenthesis by each number inside of the parenthesis.

4(12 + 3)

4 x 12 = 48 and 4 x 3 = 12

(48 + 12)

Now, add both numbers inside the parenthesis.

(48 + 12 = 60) or 60.
