I'm confused on this ​

Answer:

y=4x-13

Step-by-step explanation:

Answer:

d° = 62°

e° = 90°

f° = 27°

g° = 27°

h° = 118°

j° = 62°

k° = 63°

Step-by-step explanation:

The relationship between the given angles are;

k° = 63° (Vertically opposite angles)

63° + f° = 90° (Given complementary angles)

∴ f° = 90° - 63° = 27°

f° = 27°

g° = f° (Vertically opposite angles)

∴ g° = f° = 27°

g° = 27°

e° + 63° + f° = 180° (The sum of angles on a straight equals 180°)

∴ e° = 180° - (63° + r°) = 180° - (63° + 27°) = 90°

e° = 90°

h° = 118° (Vertically opposite angles)

118° + d° = 180° (The sum of angles on a straight equals 180°)

∴ d° = 180° - 118° = 62°

d° = 62°

j° = d° (Vertically opposite angles)

∴ j° = d° = 62°

j° = 62°

Answer: its A

Step-by-step explanation:

Answer:

Step-by-step explanation:

f(2x-3)=4x+5

Let, 2x-3=g

x=(g+3)/2

So,f(2{g+3}/2 -3)=4(g+3)/2 + 5

f(g)=2g+11

So,f(x)=2x+11

f(-2)=7 ##

Answer:

f(2x - 3) = 4x + 5

f(2x-3)=2(2x-3)+11

f(x)=2x+11

f(-2)=2×-2+11=-4+11=7

Answer:

The answer should be 15 cans GD and 25 cans CH

Step-by-step explanation:

Answer:

5 yr and 39 yr

Step-by-step explanation:

Let x = the age of the younger

then 7x + 4 = the age of the older

Now x + 7x + 4 = 44

8x + 4 = 44

8x = 40

x = 5

7x + 4 = 7(5) + 4 =  35 + 4 = 39

Check:  5 + 39 = 44

Answer:

$112.95

Step-by-step explanation:

Use the simple interest formula, I = prt

Plug in the initial amount, interest rate, and number of years

I = prt

I = (1506)(0.025)(3)

I = 112.95

So, the interest created in 3 years is $112.95

Answer:

ok so i really shouldnt get points for this, but i wanted to help. The person who solved the problem here:  https://math.stackexchange.com/questions/2911546/suppose-the-sides-of-a-triangle-form-a-geometric-progression-with-common-ratio-r     is correct, but it is not very clear. Basically, he rounded to the third decimal point (since a sqrt has infinate decimals), and this might have been what got you the wrong answer. Basically the important thing is that r has to be between the (-1+√5)/2 and (1+√5)/2, or (-1+√5)/2 < r < (-1+√5)/2

Answer:

because since the question is 639 / 6

we immediately know that 600 / 6 is 100

639 / 6 = 106.5

Answer:

You just need a little conversion to get the answer.

[tex]\frac{639}{6}=\frac{600}{6}+\frac{39}{6}\\ = 100+\frac{39}{6} >100[/tex]

Answer:

Step-by-step explanation:

Volume = 1/2 a * b*h

So

V= 1/2 (9)(6)(21)= 567 us ^3

Answer:

Angle 1 is 57 degrees

Angle 3 is 57 degrees

Angle 4 is 123 degrees

Step-by-step explanation:

Cause a straight line is 180 degrees and if angle 2 is 123 degress then angle 3 is 57 degrees and i got that by Subtracting 180-123 =57

Then for angles one you do the same maththat you do for finding angle 3

Then for angles 4 subtract 180-57=123

Answer:

no

Step-by-step explanation:

(4, -3) when plugged into the inequality x + y < 1 is not true

4 + (-3) < 1 is not true because 1 is not less than 1

Answer:

Step-by-step explanation:

Remove the brackets. Watch out for that minus sign. It affects all three terms in the right bracket.

(-3f - 4g + 9) - (2 - 6f + 5g)

-3f - 4g + 9 - 2 + 6f - 5g

+3f - 9g + 7 is your answer.

Answer:

3f−9g+7

Step-by-step explanation:

(−3f−4g+9)−(2−6f+5g)

To find the opposite of 2−6f+5g, find the opposite of each term.

−3f−4g+9−2−(−6f)−5g

The opposite of −6f is 6f.

−3f−4g+9−2+6f−5g

Subtract 2 from 9 to get 7.

−3f−4g+7+6f−5g

Combine −3f and 6f to get 3f.

3f−4g+7−5g

Combine −4g and −5g to get −9g.

3f−9g+7

the total sale was neither a profit nor loss , 0%

Step-by-step explanation:

1st table :

100%-> 9900

110%-> 10890

10890-9900=990(earned)

------------------------------------------

2nd table :

100%->9900

90%-> 8910

9900-8910=990(lost)

990-990=0

hence the total sale was neither a profit nor loss , 0%

8/6=4/3

Answer:

Area=36.66 cm^2

Step-by-step explanation:

First, you need the height.

Use the Pythagorean theorem:

hypotenuse^2=height^2+(1/2 base)^2  

It's one-half base because it's an equilateral triangle.

1/2 base =4.6

(9.2)^2-4.6^2=height^2

84.64-21.16=height^2

height^2=63.48

height=7.97

Area=(1/2)(base)(height)

Area=(1/2)(9.2)(7.97)=36.66 cm^2

Step-by-step explanation:

60 is 60 x 1, and 120 is 60 x 2

Step-by-step explanation:

The location of A is 3.2

The location of A' is 6.4

A represent pre image A' represent the new image.

The scale factor of A to A' is 2 since 3.2 x 2 =6.4

Since you didnt provide B coordinates, just multiply 2 by the B coordinate to find the B prime coordinate.

Answer: A.)The scale factor is 0.8 and the coordinates of point B prime are (–3.2, –4.8).
