Answer:

1) 26

2) 7

Step-by-step explanation:

1) f(10)= (3*10)-4 = 26

2) f(x) = 3x-4

=> 17= 3x-4

=> 17+4= 3x

=> 21= 3x

=> x= 21÷3

so, x= 7

Answer:

The answer is 3

Step-by-step explanation:

3/4x4 =3

4 x 3/4 = 3

All you are doing is reducing the numbers with the greatest common factor which is the number 4.

Answer: 213 2/3 miles

Step-by-step explanation:

first we need to set up an equation to solve

let your equation be in y=mx+b form since we are using a rate

Since this is a word problem, dissect it and match each part with a variable in the slope-intercept equation

y = Budget

m = rate

x = how many miles she can go -- the unknown variable

b = the initial fee

Your equation should be: 50 = 0.15x + 17.95

We want to soIve for x now so first get rid of the coefficient not attached to it

To do this, you do the inverse function of addition, which is subtraction

Subtract 17.95 from both sides

Your new equation will be: 32.05 = 0.15x

0.15 is still attached to x, so we want to do the inverse function of multiplication, which is division

divide both sides by 0.15

Your final answer: 213 2/3 miles

Answer:

[tex]10n \le 30[/tex]

[tex]n \le 3[/tex]

Step-by-step explanation:

Given

[tex]Total = \$30[/tex]

[tex]Cost (each) = \$10[/tex]

Required

Determine the inequality

Assume she wants to buy n CDs.

If 1 CD costs $10, then n CDs costs 10n.

So, the inequality is:

[tex]10n \le 30[/tex]

We used [tex]\le[/tex] because the amount she wants to spend cannot exceed 30

Divide both sides by 10, to solve for n

[tex]n \le 3[/tex]

The pre-image of the point is A ( -1 , 9 )

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.

A translation in the coordinate plane moves every point on a figure a given distance in a given direction. The position of any point (x, y) on the figure changes to (x + a, y + b), where a and b are real numbers.

Given data ,

To determine the coordinates of the pre-image point A, we need to reverse the translation by moving left 4 units and down 5 units from the image point B(3, 14).

Moving left 4 units from B(3, 14) means subtracting 4 from the x-coordinate:

x-coordinate of A = 3 - 4 = -1

Moving down 5 units from B(3, 14) means subtracting 5 from the y-coordinate:

y-coordinate of A = 14 - 5 = 9

Hence , the coordinates of the pre-image point A are (-1, 9)

Step-by-step explanation:

It is parallel to 2x + 3y = 12

Answer:

Y = negative x + 9

Step-by-step explanation:

Find the equation of the line for side S-

m= 4-1/1-4 = 3/-3 = -1

The Gradient is -1

Since parallel lines share the same gradient, it should be either of the first two options.

We can see side Q shares the same gradient: 3-6/6-3= -1

Find the equation of the line of side Q-

y-6= -1(x-3)

y-6=-x+3

Step-by-step explanation:

Givn : OK = 3, OJ = 30, KN = 1, JM = 3

ON=OK+KN=3+1=4

OM=OJ+JM=30+10=40

In triangles OKJ & ONM,

OKOJ=330=110

ONOM=440=110

Angle O is common in both the triangles.

Two sides are in same proportion and the included angle is common (SAS) . Hence both the triangles are similar.

That means KJNM=110 or the two sides are parallel.

Hence ˆK=ˆN,ˆJ=ˆM corresponding angles.

Two sides in each triangle that are proportional to each other, and a corresponding included angle in both triangles that are congruent, both triangles are similar.

Recall:

Two triangles can be proven to be similar by the SAS Similarity Theorem, if they both have two pairs of corresponding side lengths that are proportional to each other and also have a corresponding included angle that is congruent to each other.

Using the image given, let's determine if two of the given side lengths of each triangle are proportional to each other.

Given:

[tex]\frac{OM}{OJ} = \frac{ON}{OK}[/tex]

[tex]\frac{40}{30} = \frac{4}{3}[/tex] (proportional)

Also, <NOM and <KOJ are congruent to each other (included angles).

Therefore, since we have two sides in each triangle that are proportional to each other, and a corresponding included angle in both triangles that are congruent, both triangles are similar.

The similarity statement is: [tex]\triangle NOM \sim \triangle KOJ[/tex]

Answer:

The Bench is 450 and the Garden table is 364

Step-by-step explanation:

Total of $814 substrate our difference of $86

so 814-86= 728 divide this by the amount of furniture purchased (2)

2/ 728= 364. Add on our difference of 86 to get our larger amount of 450.

Answer:

The bench cost $364

Step-by-step explanation:

Hey there,

Before starting, you want two separate variables to represent both the table and the bench.

Let's do this...

Garden table: x

Bench: y

*Note the variables don't have to be x and y, they just have to be two different variables, I just chose x and y. Any letter works as long as they're different.

We then know that the garden table PLUS the bench had a total cost of $814.

Going back to our variables, we could represent this system by saying...

x + y = 814

(remember x is the garden table and y is the bench)

We also know that the garden table costs $86 LESS than the bench.

Going back to our variables, we could represent this by saying...

x - 86 = y

(x - 86 is basically saying that the garden table minus $86 equals the cost of the bench)

Just by looking at this, we know that y is equal to x - 86.

Here's what you have to do...

Plug in y for the first equation...

x - 86 = y

x + ( x - 86 ) = 814

Now, solve...

2x - 86 = 814

Add 86 on both sides...

2x = 900

divide by two on both sides...

x = 450

We now know that the garden table costs $450. But how do we find the cost of the bench? Plug in x back into the original equation...

x + y = 814

(450) + y = 814

subtract 450 on both sides...

You get y = 364

The bench has a total cost of $364

Answer:

a. You are looking for an annuity that will give $41,000 in 5 years with a quarterly compounding rate of 4.25%.

Convert periods and interest to quarterly rate.

Period = 5 * 4 = 20 quarters

Interest = 4.25 / 4 = 1.0625‬%

41,000 = Annuity * ( [ 1  +  i ] ^n - 1 )/i

41,000 = Annuity * ( [ 1 + 1.0625%]²⁰ - 1) / 1.0625%

41,000 = Annuity * 22.1534596596

Annuity = 41,000 / 22.1534596596

= $1,851

b. There were 20 payments of $1,851 made which totals:

= 1,851 * 20

Cash from deposits = $‭37,020‬

Cash from interest = 41,000 - ‭37,020‬ = $3,980
