Answer: x = -1, -3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Taking the square root of both sides leads to

x + 2 = ±1

which in turn comes out to  x = -2 + 1, or x = -1, and x = -2 - 1, or x = -3

Answer:

6

Step-by-step explanation:

= 3[-2(4) + 10]

= 3(-8 + 10)

= 3(2)

The function is given as  g(x) = -2x + 10 then the solution of the 3[g(4)] would be equal to 6.

A function is a type of relation, or rule, that maps one input to a specific single output.

Functions that are formed by composing two or more functions in a way that one's output is another's input are called composite functions.

They are also called functions of functions.

We have to find 3[g(4)] if g(x) = -2x + 10

3[g(4)] = 3[-2(4) + 10]

3[g(4)]  = 3(-8 + 10)

3[g(4)]  = 3(2)

3[g(4)]  = 6

Answer: $10000

Step-by-step explanation:

From the question,

Principal = $43000

Time = 5 years

Rate = Unknown

Simple Interest = $51,600 - $43000 = $8600

We need to calculate the rate of interest which will be:

Interest = PRT/100

8600 = (43000 × 5 × Rate) / 100

Cross multiply

8600 × 100 = 215000 × Rate

Rate = 860000 / 215000

Rate = 4%

Assuming Justine borrowed $50,000 instead, the yearly Interest will be:

= (50000 × 5 × 4%)

= 50000 × 5 × 0.04

= $10000

About 10 for A and B

Step-by-step explanation:

Just count the little boxes :)

Given:

Either has a school certificate or diploma or even both = 20 people

Having school certificates = 14

Having diplomas = 11

To find:

The number of people who have a school certificate only.

Solution:

Let A be the set of people who have school certificates and B be the set of people who have diplomas.

According to the given information, we have

[tex]n(A)=14[/tex]

[tex]n(B)=11[/tex]

[tex]n(A\cup B)=20[/tex]

We know that,

[tex]n(A\cup B)=n(A)+n(B)-n(A\cap B)[/tex]

[tex]20=14+11-n(A\cap B)[/tex]

[tex]20=25-n(A\cap B)[/tex]

Subtract both sides by 25.

[tex]20-25=-n(A\cap B)[/tex]

[tex]-5=-n(A\cap B)[/tex]

[tex]5=n(A\cap B)[/tex]

We need to find the number of people who have a school certificate only, i.e. [tex]n(A\cap B')[/tex].

[tex]n(A\cap B')=n(A)-n(A\cap B)[/tex]

[tex]n(A\cap B')=14-5[/tex]

[tex]n(A\cap B')=9[/tex]

Therefore, 9 people have a school certificate only.

Answer:

30

Step-by-step explanation:

60(highest) - 30(lowest) = 30(range)

Answer:

Step-by-step explanation:

3(x +2 ) = 18     {Use distributive property: a(b +c) =a*b + a*c}

3*x +3*2 = 18

3x + 6 = 18             {Subtract 6 from both sides}

     3x = 18- 6

     3x = 12          {Divide both sides by 3}

       x = 12/3

x = 4

Answer:

70

You got it correct :)

Step-by-step explanation:

[tex]\frac{28}{y} =\frac{40}{100}[/tex]

y × 40 = 100 × 28

40y = 2800

40y ÷ 40 = 2800 ÷ 40

y = 70

Answer:

G. 0.08

Step-by-step explanation:

It is actually 0.8 but putting a zero before 8 is fine.

0.0008=0.8

0.8000=X

All the angles should add up to 360°.

8x+10x+9+21x-12+90=360°

Group like terms together.

So,8x+10x+21x+9+90-12=360

39x+87=360

39x=360-87

39x=273

x=7

Answer:

∠ X = 80° , ∠ V = 60°

Step-by-step explanation:

(a)

Since XY and WX are congruent then the triangle is isosceles and the 2 base angles are congruent, that is

∠ W = ∠ Y = 50° , so

∠ X = 180° - (50 + 50)° ← sum of angles in triangle

∠ X = 180° - 100° = 80°

(b)

Since the 3 sides are congruent then the triangle is equilateral with the 3 angles congruent, each 60°

∠ V = 60°

Answer:

angle z= 96°

angle x = 33

I hope it's helps you

Answer:

z = 96

x = 33

Step-by-step explanation:

Given that g and h are parallel, we can assume that 84 and z will be equal to 180.

[tex]84 + z=180\\z= 96[/tex]

Then we make the , simple algebra work!

[tex]96 = 6x - 102\\198 = 6x\\x = 33[/tex]
