I need a lot of help sooo….

Given, A + B = 90°

Putting values, we get

7x + 4 + 4x + 9 = 90°

11x + 13 = 90°

11x = 90 - 13 = 77°

x = 7°

Now, m<A = 7x + 4

= 7(7) + 4 = 53°

Hope this helps :)

Answer:

m∠A = 53°

Explanation:

complement angle: : two angles that add up to 90 degrees.

solve:

7x + 4 + 4x + 9 = 90

7x + 4x = 90 - 9 - 4

11x = 77

x = 7

Find m∠A:

7x + 4

7(7) + 4

49 + 4

53°

Explanation:

Any time Alyssa is increasing her speed, the graph will move uphill when going from left to right.

If she slows down, then the graph will move downhill when going left to right.

Always move from left to right when reading a graph because this is how the time axis is set up.

Any flat part represents portions where her speed is constant, i.e. doesn't change.

With all that in mind, the answer is choice D because

Answer: m<XVY = 82°

Step-by-step explanation: The measure of an angle formed by two chords that intersect inside a circle is equal to half the sum of the measures of the intercepted arcs.

Since the measures of the intercepted arcs are 86° and 78°,

we can setup the equation m<XVY = 1/2(86 + 78).

So we get m<XVY = 1/2(164) or m<XVY = 82°

Answer:

y = 2

Step-by-step explanation:

Kindly view the attached image to see the rules when looking for the horizontal asymptote.

In this situation we have 2x² / x²

The powers of both are equal to each other therefore the horizontal asymptote will be at the coefficient of the numerator divided by the coefficient of the denominator.

In other words the horizontal asymptote is at y = 2/1 or just 2

Answer:

$221

Step-by-step explanation:

The original percent is always 100%. Add the markup, 70% to 100% to find the total percent charged.

100% + 70% = 170%

Change 170% to a decimal by moving the decimal two places left. 170% = 1.70

Multiply the decimal and the wholesale price.

$130 x 1.70 = $221

[tex]a[/tex] is the initial value of an exponential function and is found by substituting [tex]x=0[/tex] into the function as [tex]b^0=1[/tex]

Therefore, as y = 4 when x = 0, the initial value is 4

Answer: 6+2x

Step-by-step explanation:

6 is the fixed cost so you add six regardless of how many kilos you travel. You add the 2x because they charge 2 dollars for every extra kilometer. The x is kilometers(which you don’t know how many you travel.) so you add 6+2x to get the cost.

Linear equation is equation in which each term has at max one degree. The formula for the cost of the journey is y = $6 + $2(x).

Linear equation is equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form,

y = mx + c

Linear equation with two variables, when graphed on cartesian plane with axes of those variables, give a straight line.

The given condition can be modelled using a linear relationship.

It is given that there is a fixed charge of $6 and an additional charge of $2 per kilometre. Therefore, the total charge,y can be modeled as,

y = $6 + $2(x)

where x represents the number of kilometres

The formula for the cost of the journey in Words​ is 6 plus two times of x, where x represents the number of kilometres.

Hence, the formula for the cost of the journey is y = $6 + $2(x).

The cost per kilogram is found by dividing cost by kilograms:

honeydew:

  ($4)/(2 kg) = $2/kg

Honeydew costs $2 per kilogram.

watermelon:

Let w represent the cost per kg of watermelon. The total value of the second purchase was ...

Final Answer is [tex]480[/tex]

Step-by-step explanation:

Assume that:

First number = x

Second number = 20 - x

Putting the given conditions,

[tex]2x^{2} + 3(20 - x)^{2} [/tex]

Putting the formula (a-b)²=(a²+2ab+b²) in (20-x)²,

[tex]2 {x}^{2} + 3(20^{2} - 2 \times 20 \times x + {x}^{2})[/tex]

[tex] = > 2 {x}^{2} + 3(400 - 40x + x^{2})[/tex]

Opening the brackets,

[tex]2 {x}^{2} + 3 \times 400 - 3 \times 40x + 3 \times {x}^{2} [/tex]

[tex] = > 2 {x}^{2} - 1200 - 120x + 3{x}^{2}[/tex]

[tex] = > (2x^{2} + 3 {x}^{2}) - 120x + 1200[/tex]

[tex] = > 5 {x}^{2} - 120x + 1200[/tex]

[tex]As \: x= - \frac{b}{2a}[/tex]

[tex] = > - \frac{120}{2 \times 5}[/tex]

[tex] = > - \frac{120}{10} [/tex]

[tex] = > - 12[/tex]

Now substituting the value of x in 5x²-120x+1200,

[tex] = > (5 \times {12}^{2} )-(120 \times 12)+1200[/tex]

[tex] = > (5 \times 144)-(1440)+1200[/tex]

[tex] = > 720 - 1440 + 1200[/tex]

[tex] = > 720 - (1440 - 1200)[/tex]

[tex] = > 720 - 240[/tex]

Answer:

48.2° (1 d.p.)

Step-by-step explanation:

Start by labelling the given sides on the triangle.

The side in which the angle of interest and the right angle sits on is the adjacent side, while the side facing the right angle is the hypotenuse side (denoted by hyp).

[tex]\boxed{ \cosθ = \frac{adj}{hyp} }[/tex]

[tex]\cosθ = \frac{6}{9} [/tex]

[tex]θ = \cos^{ - 1} ( \frac{6}{9} )[/tex]

Answer:

(8, 5): No

(8, 0): Yes

(4, -2): Yes

(-6, -4) No

Step-by-step explanation:

For this question, it is very easy, you just substitute the values under (x,y) into the equation above

The equation is: 3x - 7y > 10

And the x and y values are

(x, y)

(8, 5)

(8, 0)

(4, -2)

(-6, -4)

x values: 8, 8, 4, -6

y values: 5, 0, -2, -4

An ordered pair tells you the location of a point by relating the point's location along the x-axis (the first value of the ordered pair) and along the y-axis (the second value of the ordered pair). In an ordered pair, such as (x, y), the first value is called the x-coordinate and the second value is the y-coordinate.

Now that we know everything, we set up the equation to see if the ordered pair is a solution or not

3x - 7y > 10

Let's substitute (8, 5) into the equation

3(8) - 7(5) > 10

Multiply the numbers

3(8) becomes 24 and -7(5) becomes -35

24 - 35 > 10

-11 > 10

False

So the ordered pair (8,5) is not a solution to the equation

Now for the next ordered pair: (8, 0)

3x - 7y > 10

Let's substitute (8, 0) into the equation

3(8) - 7(0) > 10

3(8) becomes 24 and -7(0) becomes 0

24 - 0 > 10

24 > 10

True

So the ordered pair (8, 0) is a solution to the equation

Now for the next ordered pair: (4, -2)

3x - 7y > 10

Let's substitute (4, -2) into the equation

3(4) - 7(-2) > 10

3(4) becomes 12 and -7(-2) becomes a positive 14, and remember that a negative times a negative becomes a positive

12 + 14 > 10

26 > 10

True

So the ordered pair (4, -2) is a solution to the equation

Now for the next ordered pair: (-6, -4)

3x - 7y > 10

Let's substitute (-6, -4) into the equation

3(-6) - 7(-4) > 10

3(-6) becomes -18 and -7(-4) becomes a positive 28

-18 + 28 > 10

10 > 10

False

Since they are the same number, they should be equal to

So the ordered pair (-6, -4) is not a solution to the equation

The first one is 1:4 and the second is 4:1.

All there is to do is simple division (or simplifying). In the first set of two numbers side length is 6 and perimeter is 24. So if it's side length to perimeter then 6 to 24 which can be simplified to 1 to 4 and just switch the numbers with perimeter to side length.

Answer:

1. Side length to perimeter = 1:4

2. Perimeter to side length = 4:1

Step-by-step explanation:

Ok, so ratios are basically a way to compare two things.

For example, if someone askes the ratio of boys to girls in Mrs. White's class. Say there are 12 boys and 9 girls.

boys to girls = 12 to 9

That's a ratio!

Ratios are typically written like "12 to 9" (with the word "to") or "12:9" (with a colon) but there are also other ways.

In THIS question, you have to find the ratio of side length to perimeter and then vice versa. So, we see that the first number listed for side length is 6, and the first number for perimeter is 24. As we look down the chart, we should notice a pattern- the perimeter is 4 times as much as the side length! Therefore, the ratio of side length to perimeter is 1:4. To find the ratio of perimeter to side length, we just switch the order of the numbers. Now it's 4:1.

There! It's pretty simple! You just are finding the unit ratio!

Answer:

f(5) = 17

Step-by-step explanation:

Using the recursive rule and f(1) = 5 , then

f(2) = f(1) + 3 = 5 + 3 = 8

f(3) = f(2) + 3 = 8 + 3 = 11

f(4) = f(3) + 3 = 11 + 3 = 14

f(5) = f(4) + 3 = 14 + 3 = 17

f(x) = abˣ

"A scientist begins with 130 milligrams", or we can word it differently.

when x = 0, f(x) = 130, which in short simply means a = 130.

"After 30 hours, 65 mg of the substance remains", worded differently.

when x = 30, f(x) = 65.
