Can Someone Please Help Y=___x+____

Answers

Answer 1

Answer:

>\/<

[tex]y = 4x - 9[/tex]

>/\<

Answer 2

Answer:

y=4x+(-9)

Step-by-step explanation:

Slope intercept form is y=mx+b

m is the slope which can be found using rise/run. In this case 4/1=4 so m=4

b is the y intercept which is the y value where the line passes through the X axis. This also can be found as the Y value where X=0 if that is easier for you. In this problem y=-9 where X=0. Therefore b=-9.

Plug these values back into the equation and you get the equation of the line in slope intercept form. For this line that is y=4x+(-9).

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

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°.

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.

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.

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)

The ratio of ebooks to novels is 4:5. if there are 32 ebooks how many novels are there?

Answers

Answer:  40 novels

================================================

Work Shown:

n = number of novels

(32 ebooks)/(n novels) = 4/5

32/n = 4/5

32*5 = n*4 ............ cross multiply

160 = 4n

4n = 160

n = 160/4 .............. dividing both sides by 4

n = 40

There are 40 novels.
