Answer:

y = 4/3x-7/3

Step-by-step explanation:

Slope intercept form is y=Mx+b; m=slope & b= y intercept

y=-4/3x+b

Now substitute x & y with the point given

(-9)=-4/3(5)+b

-9= -20/3+b

+20/3 +20/3

-7/3=b

Now substitute this into the original equation

y = 4/3x-7/3

Answer:

D) 126 in²

Step-by-step explanation:

A rectangular prism is 3 inches long, 5 inches wide, and has a height of 6 inches. What is its surface area?

The formula for the surface area of a rectangular prism =

A=2(wl+hl+hw)

Where

W= Width = 5in

H = Height = 6 in

l = Length = 3 in

Surface area =

2(5 × 3 + 6 × 3 + 5 × 6) square inches

2(15 + 18 + 30) square inches

2(63) square inches

= 126 square inches (in²)

Option D is correct

Answer:

126 in 2

Answer:

Volume = 2,258.67 cm³

Step-by-step explanation:

Volume of the object = volume of hemisphere + volume of cylinder

= ⅔πr³ +πr²h

Where,

π = 22/7

r = 7 cm

h = 10 cm

Volume = (⅔*22/7*7³) + (22/7*7²*10)

Volume = 2,258.67 cm³

Answer:

RS ≈ 6.4

Step-by-step explanation:

Using the sine ratio in the right triangle

sin39° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{QR}{RS}[/tex] = [tex]\frac{4}{RS}[/tex] ( multiply both sides by RS )

RS × sin39° = 4 ( divide both sides by sin39° )

RS = [tex]\frac{4}{sin39}[/tex] ≈ 6.4 ( to the nearest tenth )

Answer:

(x,y): (6 , -3) or (-30/7 , 33/7)

Step-by-step explanation:

6x + 8y = 12

x = y + 9 or   y = x+ 9

if x = y+9

6*(y+9) + 8y = 12

14y = -42

y = -3 and x = 6

if y = x+9

6x + 8*(x+9) = 12

14x = -60

x = -30/7   and y = 33/7

Answer:

he can buy 10 peaches.

Step-by-step explanation:

7 mangoes will be 12.25. so you subtract his original money(20) from 12.25 which gives you 7.75. then divide 7.75 by 0.75(cost of a peach) and your answer will be 10(rounded off).

Answer:

C

Step-by-step explanation:

Method A:

270 decrease 25% =

270 × (1 - 25%) = 270 × (1 - 0.25) = 202.5

202.5 increase 6% =

202.5 × (1 + 6%) = 202.5 × (1 + 0.06) = 214.65

Method B:

270 increase 6% =

270 × (1 + 6%) = 270 × (1 + 0.06) = 286.2

286.2 decrease 25% =

286.2 × (1 - 25%) = 286.2 × (1 - 0.25) = 214.65

Answer:

[tex]Amount\ at\ 2 \%=9000[/tex]

[tex]Amount\ at\ 4\% =2000[/tex]

Step-by-step explanation:

From the question we are told that

Principle [tex]P=1000[/tex]

Rate 1 [tex]r_1=2\%[/tex]

Rate 1 [tex]r_2=4\%[/tex]

Total Interest [tex]I=\% 260[/tex]

Let

Amount at [tex]2 \%=x[/tex]

Amount at [tex]4\% =11000-x[/tex]

Generally the equation for the simple interest is mathematically given as

[tex]\frac{x*2*1}{100} +\frac{(11000-x)*4*1)}{100} =260[/tex]

[tex]2x+44000-4x=26000[/tex]

[tex]2x-4x=26000-44000\\[/tex]

[tex]2x=18000[/tex]

[tex]x=9000[/tex]

[tex]Amount\ at\ 2 \%=9000[/tex]

Therefore

Amount at  [tex]4\% =11000-x[/tex]

Amount at  [tex]4\% =11000-9000[/tex]

[tex]Amount\ at\ 4\% =2000[/tex]

Answer:

18(x + 2)

Step-by-step explanation:

-4/5 ( 30x -  40) + (42x + 4) = -24x + 32 + 42x + 4 = 18x + 36 = 18(x + 2)

Answer:

18x+36

Step-by-step explanation:

1. Simplify  \frac{4}{5}(30x-40)54(30x−40)  to  \frac{4(30x-40)}{5}54(30x−40).

-\frac{4(30x-40)}{5}+42x+4−54(30x−40)+42x+4

2. Factor out the common term 1010.

-\frac{4\times 10(3x-4)}{5}+42x+4−54×10(3x−4)+42x+4

3. Simplify  4\times 10(3x-4)4×10(3x−4)  to  40(3x-4)40(3x−4).

-\frac{40(3x-4)}{5}+42x+4−540(3x−4)+42x+4

4. Simplify  \frac{40(3x-4)}{5}540(3x−4)  to  8(3x-4)8(3x−4).

-8(3x-4)+42x+4−8(3x−4)+42x+4

5. Expand by distributing terms.

-(24x-32)+42x+4−(24x−32)+42x+4

6. Remove parentheses.

-24x+32+42x+4−24x+32+42x+4

7. Collect like terms.

(-24x+42x)+(32+4)(−24x+42x)+(32+4)

8. Simplify.

18x+3618x+36

[tex]y=3x[/tex]

Step-by-step explanation:

[tex]Ax+By+C[/tex] ⇒ [tex]y=mx+b[/tex]

[tex]3x+y=0[/tex]

Since there are no coefficients on the [tex]y[/tex], you can convert the equation in one step.

Subtract [tex]3x[/tex] from both sides

[tex]y=3x+0[/tex] [tex]or[/tex] [tex]y=3x[/tex]

Answer:

answer would be (1,-1)

Step-by-step explanation:

Dialation means to multiply, so u would multiply the point where D is so in the graph it shows D is on 2, -2 so you would multiply 2 by 1/2 and -2 by 1/2 which would give you (1, -1)

Answer:

The correct answer is option B.  17

Step-by-step explanation:

It is given that, ZX bisects ∠WZY. If the measure of ∠YXZ is (6m – 12)°

To find the value of m

From the figure we can see that, triangle WYZ is an isosceles  triangle.

ZW = ZY

Then <YXZ = <WXZ = 90°

It is given ∠YXZ  = (6m – 12)°

(6m – 12)° =  90°

6m = 90 + 12  = 102

m = 102/6 = 17

Therefore the value of m = 17

The correct answer is option B.  17

Step-by-step explanation:

We need to find the value of the given expression :

30³÷(−5)

It can be written as :

[tex]\dfrac{30xy^3}{(-5xy)}=\dfrac{30}{-5}\times \dfrac{xy^3}{xy}\\\\=-6\times y^2\\\\=-6y^2[/tex]

Answer:

Radius is 3.5 cm

Diameter is 7 cm

Step-by-step explanation:

Radius is half the diameter

They give you the diameter at 7 cm

Then you have to half that to get 3.5 cm as the radius

Answer:

The answers are the diameter is 7 because whatever the line across is it's the diameter and the radios is half of what the diameter is so whatever is half of 7 is your radios.

Step-by-step explanation:

Diameter: 7

Radios: 3.5 or 3 1/2
