Answer:

Step-by-step explanation:

x+y=14

y=14-x

2x+3y=32, using y=14-x we have

2x+3(14-x)=32

2x+42-3x=32

-x+42=32

-x=-10

x=10, and since y=14-x

y=14-10=4

So Amelia made 10 two-pointers and 4 three-pointers.

Answer:

[tex]g(-2) = 25[/tex]

[tex]g(-1) = 5[/tex]

[tex]g(0) = 1[/tex]

[tex]g(1) = \frac{1}{5}[/tex]

Step-by-step explanation:

Given

[tex]g(x) = \frac{1}{5}^x[/tex]

Solving (a): When x = -2

This gives:

[tex]g(x) = \frac{1}{5}^{(-2)[/tex]

[tex]g(x) = \frac{1}{5}^{-2[/tex]

[tex]g(x) = 5^2[/tex]

[tex]g(-2) = 25[/tex]

Solving (b) When x = -1

This gives:

[tex]g(x) = \frac{1}{5}^{-1}[/tex]

[tex]g(-1) = 5[/tex]

When x = 0

This gives:

[tex]g(x) = \frac{1}{5}^0[/tex]

[tex]g(0) = 1[/tex]

When x = 1

This gives:

[tex]g(x) = \frac{1}{5}^1[/tex]

[tex]g(1) = \frac{1}{5}[/tex]

Answer:

a-16cm

b-12cm if not iwill look again

Step-by-step explanation:

Area of the parallelograms are :(a) = 16 cm² and (b) = 12 cm² which is drawn on a centimeter grid.

A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal. A parallelogram is a square and a rhombus is a square.

The formula to calculate the area of a parallelogram can thus be given as,

Area of parallelogram = b × h square units

where b is the length of the base and h is the height or altitude

For parallelogram (a),

length of the base = 4 cm

the height or altitude = 4 cm

Area of parallelogram (a) = b × h =  4 × 4

Area of parallelogram (a) = 16 cm²

For parallelogram (b),

length of the base = 2 cm

the height or altitude = 6 cm

Area of parallelogram (b) = b × h =  2 × 6

Area of parallelogram (b) = 12 cm²

(<) means "open circle to the left."

Hi there!

[tex]\large\boxed{\text{ L = 6 ft, w = 5.5 ft}}[/tex]

Use the following equation for the area of a rectangle:

A = l × w

Since the length is 5 ft less than twice the width, we can write an expression for the length in terms of the width:

l = 2w - 5

Plug the given area and expression into the equation:

33 = (2w - 5) × w

Distribute:

33 = 2w² - 5w

Move everything over to one side:

0 = 2w² - 5w - 33

Factor the equation:

0 = (2w - 11)(w + 3)

Find each w value by setting each expression equal to 0:

0 = 2w - 11

11 = 2w

w = 5.5

0 = w + 3

-3 = w

Since dimensions must be positive, the width is 5.5 ft.

Plug this value into the initial equation to solve for length:

33 = 5.5l

33/5.5 = l

l = 6 ft.

The dimensions are length = 6ft, and width = 5.5ft.

Step-by-step explanation:

The graph of the function f (x) = 4/x is shown in figure.

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The function is,

⇒ f (x) = 4 / x

Now, We can draw the function f (x) = 4 / x.

Hence, The graph of the function f (x) = 4/x is shown in figure.

Answer:

{9} Slope: -1

Y-intercept = 0

Step-by-step explanation:

Slope-----

Recall slope-intercept form

y=mx+b, with slope m and a y-intercept of b. With this in mind, we can rewrite our equation as y=−x+0

We see that our slope, or coefficient on x, is −1.

Y-intercept-----

We can rewrite this equation as:y=1x+0

The slope-intercept form of a linear equation is: y=mx+b

Where m is the slope and b is the y-intercept value.

For this equation:y=1x+0

Therefore:

The slope is m=1

The y-intercept is b=0 or (0,0)

Required

Create a function table for inputs -2, 0, 2 and 4

When x = -2

[tex]y = 4*-2 - 1 = -9[/tex]

When x = 0

Answer: correct answer is C

Step-by-step explanation:

The value of m in the figure is √126.

Option C is the correct answer.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

ΔABD is similar to ΔBCD.

This means,

The corresponding sides ratio is equal.

AB/BC = BD/CD = AD/BD

AB/m = BD/7 = 11/BD

Now,

BD/7 = 11/BD

BD² = 77

BD = √77

Now,

ΔBDC

BC² = CD² + BD²

m² = 7² + 77

m² = 49 + 77

m² = 126

m = √126

Thus,

The value of m in the figure is √126.

Given:

The rate of interest on three accounts are 7%, 8%, 9%.

She has twice as much money invested at 8% as she does in 7%.

She has three times as much at 9% as she has at 7%.

Total interest for the year is $150.

To find:

Amount invested on each rate.

Solution:

Let x be the amount invested at 7%. Then,

The amount invested at 8% = 2x

The amount invested at 9% = 3x

Total interest for the year is $150.

[tex]x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150[/tex]

Multiply both sides by 100.

[tex]7x+16x+27x=15000[/tex]

[tex]50x=15000[/tex]

Divide both sides by 50.

[tex]x=\dfrac{15000}{50}[/tex]

[tex]x=300[/tex]

The amount invested at 7% is [tex]300[/tex].

The amount invested at 8% is

[tex]2(300)=600[/tex]

The amount invested at 9% is

[tex]3(300)=900[/tex]

Thus, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.
