Answer:

a. y = 3x + 4.5 & y = 7x + 2

b. x = 0.625 (year)

c. 6.375 feet

Explanation:

Type A starts at 4.5 and Type B starts at 2 ,each year can be marked as x

type A grow 3 inches per year = 3x

type B grows 7 inches per year = 7x

y = the total height

Since they both equal to y, you can set them equal to each other

3x + 4.5 = 7x +2

After solve you get answer for b

Work:  3x + 4.5 = 7x + 2

              4.5 = 4x + 2

               2.5 = 4x

              0.625 = x

Substitute the value of x you got from part b into each equation then you will get 6.375 as your y value which is also your height

Answer:

AB = [tex]\frac{108}{7}[/tex]

Step-by-step explanation:

Δ ALM and Δ ACB are similar, then the ratios of corresponding sides are equal, that is

[tex]\frac{AM}{AB}[/tex] = [tex]\frac{AL}{AC}[/tex] , substitute values

[tex]\frac{12}{AB}[/tex] = [tex]\frac{14}{18}[/tex] = [tex]\frac{7}{9}[/tex] ( cross- multiply )

7AB = 108 ( divide both sides by 7 )

AB = [tex]\frac{108}{7}[/tex] ( = 15 [tex]\frac{3}{7}[/tex] )

Answer:

Step-by-step explanation:

ΔIJK = ΔLMN --- (given)

So,-----------------------

KI / KJ = NL / MN

19 / 40 = 60 / MN

MN = 60 × 40 / 19

MN = 126.31

The required measure of side MN will be 126.3 units.

Similar Triangles are defined as two triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides. The triangles that like one another but may not be exactly the same size are said to be similar triangles.

Given that triangle ΔIJK ~ ΔLMN in the question.

We know that Similar triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides.

As per the similarity rule of triangles, we can write the ratio as:

⇒ KI / KJ = NL / MN

⇒ 19 / 40 = 60 / MN

⇒ MN = 60 × 40 / 19

⇒ MN = 126.3157

Rounded to the nearest tenth to get

⇒ MN = 126.3

Answer: Last graph, the one with the points (1, 2), (2, 3), (3, 4), and (4, 5)

Step-by-step explanation:

We have the equation y = x + 1

Now we can replace x by different values to get pairs (x, y).

if x = 1, we have:

y = 1 + 1 = 2

then we have the pair (1, 2)

if we have x = 2, then:

y = 2 + 1 = 3

Then we have the pair (2, 3)

So we need to find the graph that has these points.

The only graph that has the points (1, 2) and (2, 3) is the last graph.

Answer:

B. 81 in.²

Step-by-step explanation:

We have been given that the trapezoid shown in the attachment has been enlarged by a scale of 1.5. We are asked to find the area of the enlarged trapezoid.

The area of the original trapezoid is 36 square inches.

Since each side of the trapezoid is enlarged 1.5 times, so the area of new trapezoid would be 2.25 times greater than area of original trapezoid.

The area would be 2.25 times greater because area is product of sum of lengths of parallel sides and height.

1.5 × 1.5 = 2.25

Area of new trapezoid: 2.25 × 36 in²

Area of new trapezoid = 81 in²

The area of the enlarged trapezoid would be 81 in² or option B.

Answer:

Subtract 5x from both sides of the equation.

7y=1−5x

x+4y=−5

Divide each term by 7 and simplify.

y=17−5x/7

x+4y=−5

Subtract x from both sides of the equation.

y=1/7−5x/7

4y=−5−x

y=1/7−5x/7

Divide each term by 4 and simplify.

y=1/7−5x/7

y=−5/4−x/4

y=1/7−5x/7
