Answer:

x = 35

Step-by-step explanation:

The segment from the vertex of the triangle is an angle bisector and divides the opposite side into 2 segments that are proportional to the other 2 sides, that is

[tex]\frac{20}{x}[/tex] = [tex]\frac{8}{14}[/tex] ( cross- multiply )

8x = 280 ( divide both sides by 8 )

x = 35

Answer:

The inequality -3x + 2y ≥ 7 matches the graph ⇒ D

Step-by-step explanation:

The slope of the line whose equation is ax + by = c is m = [tex]\frac{-a}{b}[/tex]

From the given graph

∵ The direction of the line is increased from left to right

∴ The slope of the line is positive

∵ The line is solid and the shaded area is over the line

∴ The sign of inequality should be ≥

→ We have only one answer that has a sign of inequality ≥, let us check

  its slope

∵ -3x + 2y ≥ 7

∴ a = -3 and b = 2

∵ m = [tex]\frac{-a}{b}[/tex]

∴ m = [tex]\frac{-(-3)}{2}[/tex] = [tex]\frac{3}{2}[/tex]

∴ The slope of the line is positive

∴ The inequality -3x + 2y ≥ 7 matches the graph

Answer:

a = 9, b = 3

Step-by-step explanation:

The exponential function is

y = a [tex]b^{x}[/tex]

Find a and b by using the points it passes through

Using (0, 9 ) then

9 = a [tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 )

a = 9

y = 9 [tex]b^{x}[/tex]

Using (3, 243 ) then

243 = 9b³ ( divide both sides by 9 )

27 = b³ ( take the cube root of both sides )

b = [tex]\sqrt[3]{27}[/tex] = 3

y = 9[tex](3)^{x}[/tex] ← exponential equation

Answer:

The two digit number is 35.

Step-by-step explanation:

Let xy be the two digit number

According to given statement

[tex]x+y = 8\ \ \ \ Eqn\ 1[/tex]

The place value of xy is 10x+y

Reversing the number will be: 10y+x

It is also mentioned that the new number is previous number increase by 18

So,

[tex]10y+x = 10x+y+18\\10y-y+x-10x = 18\\9y-9x = 18\\9(y-x) = 18\\\frac{9(y-x)}{9} = \frac{18}{9}\\y-x = 2\ \ \ Eqn\ 2[/tex]

From equation 2

[tex]y = 2+x[/tex]

Putting in equation 1

[tex]x+y = 8\\x+2+x = 8\\2x+2 = 8\\2x = 8-2\\2x = 6\\\frac{2x}{2} = \frac{6}{2}\\x = 3[/tex]

Putting x = 3 in equation 1

[tex]3+y = 8\\y = 8-3 = 5[/tex]

xy = 35

Hence,

The two digit number is 35.

Hope this helps!!

Step-by-step explanation:

So the four consecutive odd integers are: 51 , 53 , 55 and 57 .

If the first integer is n, then the other three are n+2,n+4 and n+6

and we have:

216=n+(n+2)+(n+4)+(n+6)=4n+12

Subtract 12 from both ends and transpose to get:

4n=204

Divide both sides by 4

to get:

n=51

So the four consecutive odd integers are:

51,53, 55 and 57.

Answer:

  608 cm²

Step-by-step explanation:

The central rectangle is 10+12+10 = 32 cm high and 16 cm wide. Its area is ...

  A = LW = (32 cm)(16 cm) = 512 cm²

Each of the two triangles on the side have an area of ...

  A = 1/2bh = (1/2)(12 cm)(8 cm) = 48 cm²

There are two triangles and one rectangle, so the total surface area is ...

  total area = rectangle area + 2 · triangle area

  total area = 512 cm² +2(48 cm²) = 608 cm²

Answer:

y = 4x + 14

Step-by-step explanation:

slope-intercept form: y = mx + b

Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]

To write the equation in y = mx + b form, we need to find the slope(m) and the y-intercept(b) of the equation.

To find the slope, take two points from the table(in this example I'll use points (0, 14) and (1, 18)) and input them into the slope formula:

[tex]\frac{18-14}{1-0}[/tex]

Simplify:

18 - 14 = 4

1 - 0 = 1

[tex]\frac{4}{1}=4[/tex]

The slope is 4.

To find the y-intercept, input the values of the slope and one point(in this example I'll use point (1, 18)) into the equation format and solve for b:

y = mx + b

18 = 4(1) + b

18 = 4 + b

14 = b

The y-intercept is 14.

Now that we know the slope and the y-intercept, we can write the equation:

y = 4x + 14

Answer:

- 2

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ - 4, 3 ] , then

f(b) = f(3) = 3² - 3 - 8 = 9 - 3 - 8 = - 2

f(a) = f(- 4) = (- 4)² - (- 4) - 8 = 16 + 4 - 8 = 12 , tus

average rate of change = [tex]\frac{-2-12}{3-(-4)}[/tex] = [tex]\frac{-14}{7}[/tex] = - 2

Answer:

1 cup of sugar for every 2 cups of flour 1:2

Step-by-step explanation:

The ratio of sugar to flour for chocolate chip cookies, to maintain the same taste, will be 1/2.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

A bakery mixes cookie dough in large batches.

For chocolate chip cookies, 10 cups (2,365.88 ml) of sugar and 20 cups (4,731.76 ml) of flour are needed.

Then the ratio of sugar to flour for chocolate chip cookies to maintain the same taste, will be

Let S be the amount of sugar and F be the amount of the flour.

Then the ratio of sugar to flour will be

S / F = 10 / 20

S / F = 1 / 2

Thus, the ratio of sugar to flour for chocolate chip cookies, to maintain the same taste, will be 1/2.
