Answer:

The point is not a solution of the two equations

Step-by-step explanation:

2x+y=4

y=-2x+4

Subsitute it into the other equation

2x+7(-2x+4)=14

2x-14x+28=14

-12x+28=14

-12x=-14

x= 7/6 or 1.17

Plug this back into the original equation

y=-2x+4

y=-2(1.17)+4

y=1.66

The solution of these two equations is (1.17, 1.66) which doesn't match the given point of (4,-4), so the point is not a solution of the two equations.

The measure of angle A from the given right angle triangle ABC is 55.15°.

Heights and Distances is a study about the applications of Trigonometry. It has many real-life applications, such as measuring the object’s height, depth of the object, the distance between two celestial objects etc. The formulas and the ratios of trigonometry are helpful in the study of heights and distances.

From the given right angle triangle ABC, we have

AB=7 units and AC=4 units

Now, cosA=AC/AB

cosA=4/7

Solve the trigonometric equation by isolating the function and then taking the inverse. Use the period to find the full set of all solutions.

A= 55.15°

Therefore, the measure of angle A is 55.15°.

Answer:

x=85

y=45

Step-by-step explanation:

using the sum of a straight angle:

x+95=180

x=85

then we can use the sum of the inner angles of a triangle:

50+85+y=180

y=45

Answer:

So, the longest toy car length is [tex]2\frac{7}{8}inches[/tex]

Step-by-step explanation:

Given - Aiden has two toy cars that measure two and one fourth inches,

            three that measure two three eight inches, one that measures two

            and seven eights inches, one that measures 2 and one eights

            inches, and one that measures two and three fourths inches.

To find - How long is Aiden's longest toy car.

Proof -

Measure of 1st car - 2 inches

Measure of 2nd car - [tex]\frac{1}{4} inches[/tex] = 0.25 inches

Measure of 3rd car - [tex]2\frac{3}{8} inches[/tex] = 2.375 inches

Measure of 4th car - [tex]2\frac{7}{8}inches[/tex] = 2.875 inches

Measure of 5th car - [tex]2\frac{1}{8}inches[/tex] = 2.125 inches

Measure of 6th car - [tex]2\frac{3}{4}inches[/tex] = 2.75 inches

So, the longest toy car length is [tex]2\frac{7}{8}inches[/tex] (2.875 inches )

Blue balloons : 63, 7, 14

Red balloons : 45, 5, 10

14 balloons in a group that has 10 red balloons

Step-by-step explanation:

First, 63/9 = 7, so 45/9 = 5.

Second,  5 x 2 = 10, so 7 x 2 = 14

Answer:

(5h-4t)(5h+4t)

Step-by-step explanation:

25h² - 16t²

adding  and subtracting 20ht from it        (√25 and √16 = 5x4 = 20):

25h² + 20ht - 20ht -16t²

factor:

(5h-4t)(5h+4t)

Answer:

(5h - 4t)(5h + 4t)

Step-by-step explanation:

25 h² - 16t² ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

Then

25h² - 16t²

= (5h)² - (4t)²

= (5h - 4t)(5h + 4t) ← in factored form

Answer:

f(x) = (x+5)(x-1)(x-3)

Step-by-step explanation:

From the graph, we have that the function intercepts the x-axis at the points x = -5, 1,3

From here, we have

x = -5

x = 1

x = 3

So we have the factors as;

x + 5, x - 1 , x - 3

So what this mean is that we have the function as;

f(x) = (x+5)(x-1)(x-3)

Answer:

4th root of 16 ;

4 = index ; 16 = radicand ;

2

Step-by-step explanation:

Given the expression :

⁴√16 represents the 4th root of 16

In the expression stated above :

The index = 4 ; number to the left of the root symbol

Radicand = 16 ; number under the square root symbol ` Sqareroot (√) is a radical symbol, and the number under the radical square root Symbol is called the radicand.

Hence. The 4th root of 16:

⁴√16 ; using a calculator gives 2.

With two obtained as the 4th root, the 4th power of 2 should give 16

2⁴ = 2 * 2 * 2 * 2 = 16

Answer:

The first transit on one side of the trench is 18 ft higher than the other side of the trench. The transit is set at 4.5 above ground, therefore the transit lens is 18' + 4.5' = 22.5' above the location on the other side of the trench. The angle of depression is the angle formed by the horizontal and the line of sight to the other side and it is given as 31°. This forms a right angle triangle with height of 22.5' and an interior angle of 31°, Then

tan( 31°) = Height / base, with the base representing the width of the trench

base = Height / tan(31°) = 22.5' / tan(31°) = 37.45' is the width of the trench

Answer:

So the trench is 37.5 feet wide

Step-by-step explanation:

The trench with telescope is 18 feet higher than the other.

The height of telescope is 4.5 feet.

Total height = 18 + 4.5 = 22.5

Now, we can see in the figure that the distances between telescope and the opposite trench, the height and width makes a right angled triangle.

So, perpendicular = total height = 22.5

base = wideness of the trench

We know,

Tan 31 = p/b

tan 31 = 22.5/b

b = 22.5 / 0.6

b = 37.5
