Answer:

17

Step-by-step explanation:

Given the limit of a function expressed as;

[tex]\lim_{x \to 3} x^2 + 3x - 1[/tex]

Substitute x = 3 into the function to have;

[tex]= 3^2 + 3(3) - 1\\= 9 + 9 -1 \\= 18 - 1\\= 17[/tex]

Hence the limit of the function as x tends to 3 is 17

Answer:

[tex]x = 26[/tex]

Step-by-step explanation:

Supplementary Angles add up to 180.

Angle C and Angle D add up to 180.

[tex]128 + 2x = 180[/tex]

[tex]2x = 52[/tex]

[tex]x = 26[/tex]

Answer:

y + 13 = 5(x + 2)

Step-by-step explanation:

the point is (-2 , -13)

Point slope form is: y - y1 = m(x - x1)

y1= -13

x1= -2

y - -13 = 5 (x - -2)

y +13 = 5(x+2)

Answer:

A) -18 B) r=10 C) x=-4

Step-by-step explanation:

A) 1d + 12 = 14-20

Step 1: Simplify both sides of the equation.

1d+12=14−20

d+12=14+−20

d+12=(14+−20)(Combine Like Terms)

d+12=−6

d+12=−6

Step 2: Subtract 12 from both sides.

d+12−12=−6−12

d=−18

Answer:

d=−18

B) 4(20+5) = 10r

Step 1: Simplify both sides of the equation.

100=10r

Step 2: Flip the equation.

10r=100

Step 3: Divide both sides by 10.      

r=10

C) -2(5 + x) - 1 = 3(x + 3)

Step 1: Simplify both sides of the equation.

−2(5+x)−1=3(x+3)

(−2)(5)+(−2)(x)+−1=(3)(x)+(3)(3)(Distribute)

−10+−2x+−1=3x+9

(−2x)+(−10+−1)=3x+9(Combine Like Terms)

−2x+−11=3x+9

−2x−11=3x+9

Step 2: Subtract 3x from both sides.

−2x−11−3x=3x+9−3x

−5x−11=9

Step 3: Add 11 to both sides.

−5x−11+11=9+11

−5x=20

Step 4: Divide both sides by -5.

x=−4

Answer:

Interest = $ 90000

Step-by-step explanation:

Given, Principal= $15000

Rate = 3%

Time = 5 years

Interest = P × R × T/100

Therefore, Interest = 15000 × 3 × 5/100

(dividing 100 by 5 to get 20)

= 15000 × 3 × 20

= 90000

Answer:C-The Cell is surrounded by a cell membrane-bound organelles.

Step-by-step explanation: Prokaryotes have a cell wall and a Eukaryote cells don’t have a cell wall.

the measure of the side = of the measure of radius because the regular hexagon have 6 sides = at each others

meaning the measure the perimeter is = 6 times the radius

and the radius = 8cm

so perimeter = 6× 8 cm

perimeter = 48cm

since the apothem is the segment perpendicular to a side thought the center and those segment are not promotional we have the notation as

r square root of 3 divided by 2

r = radius = 8 cm

by apply the formula

8square root 3 divided by 2

so the area will be

since the perimeter is 48cm

and the apothem is 8 square root of 3 divided 2

so the area will be 48 times 8 square root of 3 divided by 2 = 384 square of 3 divided by 2 .

hope that helps.

Answer:

x = -2 y = -4

x = -1 y = -1

x = 0 y = 2

x = 1 y = 5

Answer: 6 A

Step-by-step explanation:

Given

Current varies directly with Voltage

i.e.

[tex]I\ \propto V\ or\\V\ \propto\ I\\V=IR[/tex]

when V=12 V, I=4 A i.e.

[tex]\Rightarrow 12=4R\\\Rightarrow R=3\ \Omega[/tex]

When V=18 V

[tex]\Rightarrow 18=I\times 3\\\Rightarrow I=6\ A[/tex]

Current is  6 Ampere

answer:

no

step-by-step explanation:

step one- cross multiply

3*15=4*6

step two- multiply

3*15=45 4*6=24

step three- simplify

45=24

45 and 24 aren't equal, therefore 3/4 and 6/15 are not proportional

good luck :)

i hope this helps

have a nice day !!

Answer:

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

3/8=x/24 (cross multiplication)

3*24=8x (we don't need to multiply 3 with 24 bc we will divide both sides by 8 so it will be easier to find the final value)

x=9

Answer:

x = 9

Step-by-step explanation:

8: 24

Multiply 3

8 x 3 = 24

3 : x

Multiply 3

3 x 3 = 9

x = 9

c) by enlarging the digram by 150% your bassically tripling the values inside and outside the shape which explains why the new P"Q" is 3 times larger than the smaller one (Translate this)

Step-by-step explanation:

Answer:

17 + m ≤ 65

Step-by-step explanation:

Maximum distance = 65 miles

Number of miles already ridden = 17

Expression to represent how many more miles, 'm' she can ride ;

Number of miles already ridden + m ≤ maximum distance

17 + m ≤ 65

m ≤ 65 - 17

m ≤ 48

The amount of additional miles Lyla can ride is at most 48 miles

Answer:

132.

Step-by-step explanation:

If 12% are sold then 100-12 = 88% are unsold.

12% = 18 oranges

1%   =  18/12 = 1.5 oranges,

88% = 1.5 * 88 = 132.

Answer:

C

Answer:

1824 in2

Step-by-step explanation:

sqaure = 48 x 32 = 1536 in2

Triangle = (12 x 48) / 2 = 288 in2

total area = 1536 + 288 = 1824 in2

Step-by-step explanation:

Answer:

A  a.  25 minutes

Step-by-step explanation:

Let x = time in minutes.

Aquarium I contains y water at time x.

y = 4.6 + 1.2x

Aquarium II contains y water at time x,

y = 54.6 - 0.8x

We want the amounts of water to be equal, so we set the right parts of the equations equal and solve for x, the time in minutes.

4.6 + 1.2x = 54.6 - 0.8x

Subtract 4.6 from both sides.

Add 0.8x to both sides.

2x = 50

Divide both sides by 2.

x = 25

Answer:

-3

Step-by-step explanation:

-9u+9u is 0 so all you are left with is -3

Answer:

-3

Step-by-step explanation:

-9u + 9u - 3

-9u and 9u cancel out, so it simplifies to -3
