3x-4=y

Answers

Answer:

answer is x=3 and y=5.... so it is (3,5)

Step-by-step explanation:

you want to combine them so y=3x-4 so subsitute y

-2x+5(3x-4)=19

-2x+15x-20=19

            +20   +20

13x=39

---    ---

13     13

x=3

now subsitute 3 into x into any problem...

3(3)-4=y

What is arithmetic progression?

A sequence in which the next term in the sequence is obtained by adding a constant to each term is known as an arithmetic progression. The common difference is the added constant. It is a succession to such an extent that the contrast between any two sequential terms in the grouping is dependably a consistent.

Consider the terms of an arithmetic progression sequence as n1, n2, n3, n.

Given a series 29, 38, 47, ….

for an AP aₙ = a₁ + (n - 1)d

where a₁ = first term of AP

n = number of terms, and d = difference between the terms

here d = 9, n = 11 and a₁ = 29

a₁₁ = 29 + (11 - 1)x9

a₁₁ = 29 + 10 x 9

a₁₁ = 119

Hence the term is 119.

I need help solving this equasion

Answers

70+60+x=180
130+x=180
X=50
Angles 60°, 70° and y form a straight line.
Angle on a straight line is 180°
So to get y it will be 180°-(60°+70)
Which is equal to 180°-130°= 50°
Y= 50°
Y and x are vertically opposite angles and vertically opposite angles are equal so therefore x=y and y=50° so x is also equal to 50° or also to find x you could do the same method as the way to find y. Angles 60°, 70° and x form a straight line. So 180°- (60°+70°)= 180°-130°=50°
X=50°.

A. y + 3 = -5(x - 1)
B. y + 3 = 5(x - 1)
C. y - 3 = 5(x+1)
D. Y-3 = -5(x + 1)

Answers

The point-slope form of the line in the graph is y-3 = 5(x+1). The correct option is C.

What is the point-slope form of the line?

The point-slope form of the line is y-y₁ = m( x-x₁)

Here, m is the slope of the line.

The graph given in the question has a slope of 5

It passes through the point ( -1,3)

The point slope form of the line is

y - 3 = 5 ( x - (-1))

y-3 = 5(x+1)

This is represented by option C.

Hi can anyone please help me with this problem, I’d really appreciate it

Answers

We can start this equation off by noticing the fact that this is a linear equation, which we can write in the form of: [tex]mx+b[/tex]. We can plug in our x values and y values given. I am going to start on the second line:

We plug in the given point: [tex](0,-3.2)[/tex].

[tex]-3.2=m(0)+b\\-3.2=b[/tex]

We can also plug in the point [tex](4,0)[/tex] to get:

[tex]0 = m(4) -3.2[/tex]

We get [tex]m = 0.8[/tex]

Therefore, our equation for the SECOND line is:

[tex]y = 0.8m - 3.2[/tex]

Hope that this helps you do the first line.

Answer: what r u supposed to figure out

Step-by-step explanation:

Answer:

See below

Step-by-step explanation:

Given is the piecewise function.

It has three different pieces.

The first piecef(x) = 2, with x ≤ -2

Plot the point (-2,2) and draw a horizontal line to the left from this point

The second piecef(x) = 1/2x + 3, at the interval -2<x≤1

Plot two border points at x = -2 and x = 1:

f(-2) = 1/2*(-2) + 3 = 2, point (-2, 2)

and

f(1) = 1/2*1 + 3 = 3.5, point (1, 3.5)

Connect these two points with a line segment

The third piecef(x) = -7/8x + 35/8, at x > 1

Plot two points at x = 1 and x = 5 (5 is an example, it could be anything > 1)

f(1) = -7/8*1 + 35/8 = 28/8 = 3.5

and

f(5) = -7/8*5 + 35/8 = 0

Connect the two points (1, 3.5) and (5, 0) and extend the line to the right

Remember the point (-2,2) belongs to the first piece and the point (1, 3.5) belongs to the second piece.

Step-by-step explanation:

Right Triangles

The trigonometric ratios (sine, cosine, tangent, etc.) are defined as relations between the triangle's side lengths.

The tangent ratio for an internal angle A is:

[tex]\displaystyle \tan A=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]

The image below shows the situation where Ms. M wanted to estimate the height of the Republic Plaza building in downtown Denver.

The angle A is given by his phone's app as A= 82° and the distance from her location and the building is 100 ft. The angle formed by the building and the ground is 90°, thus the tangent ratio must be satisfied. The distance h is the opposite leg to angle A and 100 ft is the adjacent leg, thus:

[tex]\displaystyle \tan 82^\circ=\frac{h}{100}[/tex]

Solving for h:

[tex]h = 100\tan 82^\circ[/tex]

Computing:

h = 711.5 ft

We must add the height of Ms, M's eyes. The height of the building is

711.5 ft + 5 ft = 716.5 ft

The height of the building is 717 ft
