can someone plz help i need to graph it and identify the x-intercept

Answers

Answer:

(-7/2,0) is the x intercept

Step-by-step explanation:

1. y+3 = -6/7x

2. -3 -3 ....subtract 3 from both sides to isolate the variable y

y= =-6/7x -3 ....is your new equation

You graph it by putting your point on negative three and then counting 6 units down and 7 units right.

For the x intercept you set y to 0 and solve for x

0= -6/7x -3

+3 +3 ...to both sides

3= -6/7x .....divide both sides by -6/7

-7/2=x

put it in as a coordinate

[tex]x - 5 + 5 = x[/tex]
[tex] \frac{1}{3}(9 + 3) = 3 + 1 [/tex]

Answers

Answer:

0* 1/9*9=0

Step-by-step explanation:

The zero property of multiplication states that any non-zero number multiplied by zero will equal zero.

it can't be the first one, since there's no zero in it, and the answer isn't zero

it can't be the second one since there's no multiplication illustrated.

The third one is an option, since there is a zero and it's being multiplied by two non-zero numbers, and the answer is 0

the fourth one isn't an option since there's no multiplication

the fifth one isn't an option since there is no 0's there.

The table below represents a linear function f(x) and the equation represents a function g(x):

Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)

Part B: Which function has a greater y-intercept? Justify your answer. (4 points)

(10 points)

Answers

Answer:

Step-by-step explanation:

Part A

for f(x) slope between points (-1,-6) and (1,0)

m= y2-y1/x2-x1 = -6-0/-1-1 = -6/-2= 3

for g(x) slope m=4 because we compare to equation y=mx+b the given equation g(x)=4x-5

The slope of f(x) is 3 and the slope g(x) is 4 so the line of g(x) is steeper

part B

The y intercept for g(x) is (0, -5)

The equation of f(x) can be found

y-y1 =m(x-x1) take any point for example point (1,0)

y-1 =3(x-0)

y=3x+1 so the y-intercept is at (0,1)

The y-intercept for f(x) is greater at y=1 then the one of g(x) at y=-5

B is between A and C. If AB = 2x + 1, BC = x, and AC = 22. Find AB.

Answers

Answer:

Step-by-step explanation:

AB + BC = AC

2x + 1 + x = 22

3x + 1 = 22

3x = 22 -1

3x = 21

x = 21/3

x = 7

AB = 2*7 +1

= 14 + 1

The equation for line p can be written as y = 1/4x + 3. Line q includes the point (-1, 5) and is
perpendicular to line p. What is the equation of line q?

Answers

Answer:

[tex]y=-4x+1[/tex]

Step-by-step explanation:

To get this, use the following steps:

1) Knowing that line q is perpendicular to the line p, the slope of line q must be the negative reciprocal of the slope of line p. Thus the slope is [tex]-(\frac{1}{4})^{-1} = -4[/tex]

2) To find the equation, plug in the point given:

[tex]5 = -4(-1) + b[/tex]

[tex]b = 1[/tex]

3) The equation of line q is thus:

[tex]y= -4x+1[/tex]

Car A is traveling east at a steady speed of 45 miles per hour. After 2 hours, it is 100 miles east of Johnstown

Car B is traveling east on the same road. it’s distance east of Johnstown is represented by the graph.

Where were the two cars in relation to each other when they began traveling?

A. Car B was 10 miles east of car A

B. Car A was 45 miles east of car B

C. Car A was 10 miles east of car B

D. Car B was 40 miles east of car A

Answers

Answer:

The correct option is;

A. Car B was 10 miles east of car A

Step-by-step explanation:

The given parameters are;

The speed of car A = 45 miles per hour

The direction of car A = East

The distance of car B from Johnstown after 2 hours = 100 miles east

The direction of Car B = East

The distance of car B from Johnstown is given on the graph

Therefore, the initial distance of car A from Johnstown when car A began driving is given as follows;

The initial distance, east, of car A from Johnstown = 100 - 2 × 45 = 10

∴ The initial distance, east, of car A from Johnstown = 10 miles

From the graph, the initial distance, east, of car B from Johnstown = 20 miles

Therefore, car B was 10 miles east of car A

Answer:

Car B was 10 miles east of car A

Sarah said that 26÷8 is the same as/equal to 14÷4 and the answers are "3r2". What did Sarah do wrong? 5th grade math help fir my daughter. I think Sarah meant: 26÷8 is the same as or equal to 13÷4 instead of 14÷4 which is what she did wrong?

Answers

Answer:

Yes

Step-by-step explanation:

Yes, that is exactly what Sarah did wrong. Apparently, she tried to divide both the numerator and denominator in this problem by 2 (half) but divided the numerator incorrectly. 26 divided by 2 would equal 13 but Sarah mistakenly calculated it as 14 which would give her a totally different value when divided by the new denominator. If were to have divided correctly it would give her [tex]\frac{13}{4}[/tex] which is the same as [tex]\frac{26}{8}[/tex]

I believe the measurement of AB is 30 degrees

Answer:

30 degrees

Step-by-step explanation:

So a complete circle consists of 360 degrees but we are trying to find what ADB equals so we are going to subtract BDC and ADC from 360:

BDC = 150

The graph does not say what ADC equals so we are going to look at the graph and see that ADC is half of the circle so we are going to divide 360 by 2:

360/2 = 180

So ADC equals 180, since we know what ADC and BDC equal we are going to add them together and then subtract them from 360:

180 + 150 = 330

360 - 330 = 30

So ADB = 30 degrees

Hope this helps!
