Answer 1

Answer:

[tex]y=\frac{6}{5}x-8[/tex]

Step-by-step explanation:

we know the slope (or m in y=mx+b) is 6/5 we just need to solve for b

we will do this by plugging in the required coordinates

-2=(6/5)*5+b

-2=6+b

-8=b

put it all together

Answer 2

Answer:

y = [tex]\frac{6}{5}[/tex] x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = [tex]\frac{6}{5}[/tex] , then

y = [tex]\frac{6}{5}[/tex] x + c ← is the partial equation

To find c substitute (5, - 2) into the partial equation

- 2 = 6 + c ⇒ c = - 2 - 6 = - 8

y = [tex]\frac{6}{5}[/tex] x - 8 ← equation of line

angle c = ___ degrees

Answers

Answer:

angle c = 83 degrees

Step-by-step explanation:

Opposite angles of an inscribed quadrilateral add up to 180 degrees.

According to the rule, <D and <B add up to 180° and same for <A and C.

This means that the sum of (x + 100) and (3x) equal 180.

Therefore (x + 100) + (3x) = 180 →

4x + 100 = 180

–100 –100

4x = 80

÷4 ÷4

x = 20.

Since x = 20, <A = 5x – 3 = 5(20) – 3 = 97.

Since <A + <C = 180.

97 + <C = 180 → 97 + <C = 180

–97 –97

<C = 180 – 97 = 83°

3 Amy wants new skirting boards in her living room.

900 mm
fireplace
1.2m
Skirting boards come in lengths of 2.4m
The lengths of skirting board can be cut and joined.

Answers

Answer:

skirting boards lenghts 11.31 m

Step-by-step explanation:

1) find the area A=LxW

A= 6.5 x 4.5= 29.25 m2

2) Once you have found the area you subtract it from the doorway and fireplace

doorway 900 mm= 0.9

fireplace 1.2m

29.25-0.9- 1.2= 27.15 m2

3) then you find the perimeter

6.5+4.5+6.5+4.5= 22

22-0.9-1.2= 19.9

you divide the answer with the skirting board lenghts= 19.9: 2.4= 8.29

which is approximately 9m of skirting board

Bill has saved $825 from his last 8 paychecks. He saved either $75 or $150 a paycheck. Formulate and solve a system of equations. to determine how many times bill saved $75 from his paycheck.

Answers

Answer: 5 times

Step-by-step explanation:

Let the number of times that he saved $75 be x.

Let the number of times that he saved $150 be y.

Therefore, based on the information given in the question, we can form an equation which will be:

x + y = 8 ...... i

75x + 150y = 825 ....... ii

From equation I,

x + y = 8

y = 8 - x....... iiii

Put equation iii into ii and this will be:

75x + 150y = 825

75x + 150(8 - x) = 825

75x + 1200 - 150x = 825

75x - 150x = 825 - 1200

-75x = -375

x = 375/75

x = 5

He saved $75 5times from his paycheck.
