Can someone please help me with this

Answer:

the answer is x= -3

y = -14

It is a geometric series.

The ratio of the second to first term is= [tex]\frac{4}{10}=\frac{2}{5}[/tex]

The ratio of the third to second term is= [tex]\frac{\left(\frac{8}{5}\right)}{4}=\frac{2}{5}[/tex]

The ratio of the fourth to third term is=[tex]\frac{\left(\frac{16}{25}\right)}{\left(\frac{8}{5}\right)}=\frac{2}{5}[/tex]

Since the common ratios are same so it is a geometric series.

Answer:

Either (-4, 3) or (-4, 5).

Step-by-step explanation:

A function is a relation when each input has exactly one output. The inputs must not repeat in a function.

In the relation given, the input '-4' repeats.

{(-4,3), (-5, 6), (1, 0),(-4,5), (9,5), (0, -7)}

If we remove either (-4, 3) or (-4, 5), it would make the relation a function.

Explanation:

Given the two baselengths, and the perpendicular height of the trapezoid, you can actually find the perimeter through the pythangorean theorem because the perpendicular height or height that forms a right or 90 degree angle makes a right triangle(2 be exact because this is an isoceles trapezoid which has two adjacent right triangles).

This is true of the trapezoid is icosceles.

Answer:

You cannot find the perimeter with numbers given.

Step-by-step explanation:

The top length, base length, and height are not sufficient to determine the perimeter of a trapezoid

Answer: BC=8 units

Step-by-step explanation:

So in this figure, this triangle, that is a parallelogram named DFCE , and one of their property three yeti you add learn you learned is that a parallelogram has like rectangle two sides per two that are parallel and have the same measure ( but you can also use the little lines that show who is the same as who ) in this one you can write an equality: CE=FD=4. Then there is the same two lines on the EB segment so EB=4 . Then we can write that BC= BE + EC

BC= 4+4

BC= 8 units

Step-by-step explanation:

Use cross product to determine if the two ratios form a proportion. Here we can see that 2/16 and 5/40 are proportions since their cross products are equal. Percent means hundredths or per hundred and is written with the symbol, %. Percent is a ratio were we compare numbers to 100 which means that 1% is 1/100.

Answer:

The proportion is a general case of percentage.

Step-by-step explanation:

Proportion is a general case of percentage.

It describes how much of the total a particular sample is.

For example, if a pie contains eight slices and you have five, the proportion is 5/8.

You have a total of five out of eight.

A percent (the number of parts out of 100) is a special case of proportion where the denominator (“whole”) equals 100 parts.

I suspect that percentages were created to allow a normalized comparison of proportions when the total number of parts was not the same.

Imagine a small pizza with 6 slices and a large pizza with 8 slices.

If Tom got 4 from the first and Ram got 5 from the second, it is not immediately clear who got more from the second.

Converting 4/6 and 5/8 to percentages (66.7 and 62.5) allows you to see when the denominator equals who got relatively "more".

Furthermore, I suspect that 100 was used because we live in a 10-base world (we have 10 fingers, which makes it natural).

Answer:

Congruent means same shape and same size. So congruent has to do with comparing two figures, and equivalent means two expressions are equal. So to say two line segments are congruent relates to the measures of the two lines are equal. Comment on David Severin's post “Congruent means same shape and same size.

Answer:

6x²+36x+22

Step-by-step explanation:

Surface Area = 2(wl + hl + wh)

Length = (x+3)

Width   = (x+7)

Height  = (x-1)

Surface Area = 2((x+7)(x+3) + (x-1)(x+3) + (x+7)(x-1))

Then simplify

2((x+7)(x+3)+(x−1)(x+3)+(x+7)(x−1))

=(2)((x+7)(x+3)+(x−1)(x+3)+(x+7)(x−1))

=(2)((x+7)(x+3))+(2)((x−1)(x+3))+(2)((x+7)(x−1))

=2x²+20x+42+2x²+4x−6+2x²+12x−14

Answer: 9 gallons

Step-by-step explanation:

Given: Ratio of colors in painting:

4 parts blue, 3 parts red, and 3 parts green.

Total parts = 4+3+3 =10

Fraction of blue = [tex]\dfrac{\text{Number of parts of blue}}{\text{total parts}}=\dfrac{4}{10}[/tex]

Since, Quantity of blue color used = 12 gallons

Let total quantity of color be x,

[tex]\dfrac{4}{10}x=12\\\\\Rightarrow\ x=\dfrac{120}{4}=30\text{ gallons}[/tex]

Total color used = 30 gallons

Color used for green part only = [tex]\dfrac{3}{10}\times30 = \text{9 gallons}[/tex]

Hence, 9 gallons of paint were needed for the green part of the painting.

If DE KL, then M > F. Choose the relationship symbol to make a true statement.

Step-by-step explanation:

slope= (x2-xl)(y2-y1)

Answer:

Step-by-step explanation:

y - 3 = - [tex]\frac{4}{3}[/tex] ( x + 1 )

y = - [tex]\frac{4}{3}[/tex] x - [tex]\frac{4}{3}[/tex] + 3

y = - [tex]\frac{4}{3}[/tex] x + [tex]\frac{5}{3}[/tex]

7 = - [tex]\frac{4}{3}[/tex] p + [tex]\frac{5}{3}[/tex]

[tex]\frac{4}{3}[/tex] p = - 7 + [tex]\frac{5}{3}[/tex]

p = ( - [tex]\frac{16}{3}[/tex] ) × [tex]\frac{3}{4}[/tex] = - 4

Answer:

b = 90

Step-by-step explanation:

Sum the interior angles of the pentagon and equate to 540

Starting from the top and going clockwise

b + b + 45 + 90 + 2b - 90 + [tex]\frac{3}{2}[/tex] b = 540 ← simplify left side

[tex]\frac{11}{2}[/tex] b + 45 = 540 ( multiply through by 2 to clear the fraction )

11b + 90 = 1080 ( subtract 90 from both sides )

11b = 990 ( divide both sides by 11 )

b = 90

Thus

b + 45 = 90 + 45 = 135

2b - 90 = 2(90) - 90 = 180 - 90 = 90

[tex]\frac{3}{2}[/tex] b = [tex]\frac{3}{2}[/tex] × 90 = 135

The angle measure from the top clockwise are

90°, 135°, 90°, 90°, 135°

Answer:

Step-by-step explanation:

The functions are:

(a), (c), (d), (e).

Relations may or may not represent a function.

The relations that are functions are (a), (c), (d), (e)

Graph (a) shows a linear relationship, and all linear relations are functions.

Graph (b) fails the vertical line test, because an x value corresponds to multiple y values; so graph (b) is not a function.

Similarly, ordered pair (f) is not a function because an x value corresponds to multiple y values

Other relations (c), (d) and (e) are functions

Hi there! :)

[tex]\large\boxed{x = -6}[/tex]

Solve for x:

4x + (-3) = 5x + 3

Adding a negative number is simply subtracting, therefore:

4x - 3 = 5x + 3

Subtract 4x from both sides:

4x - 4x - 3 = 5x - 4x + 3

-3 = x + 3

Subtract 3 from both sides:

-3 - 3 = x + 3 - 3

-6 = x

Answer:

[tex]x=-6[/tex]

Answer:

The smaller integer is -3 and the greater integer is -2

Step-by-step explanation:

Equations

Let's call

x = the smaller integer

x + 1 = greater consecutive integer

The relationship between them is that twice the smaller is four less than the greater:

2x = x + 1 - 4

Subtracting x:

x = 1 - 4

Operating:

x = -3

x + 1 = -2
