Answer:
Step-by-step explanation:
(-4 , -7) ; slope = (2/3)
y -y1 =m(x-x1)
[tex]y -[-7]=\frac{2}{3}(x-[4])\\\\y+7 = \frac{2}{3}(x+4)\\\\y+7=\frac{2}{3}x+4*\frac{2}{3}\\\\y +7 = \frac{2}{3}x+\frac{8}{3}\\\\y=\frac{2}{3}x+\frac{8}{3}-7\\\\y=\frac{2}{3}x+\frac{8}{3}-\frac{7*3}{1*3}\\\\y=\frac{2}{3}x+\frac{8}{3}-\frac{21}{3}\\\\y=\frac{2}{3}x-\frac{13}{3}[/tex]

Answer this for me please!
what is the slope in this equation y=10+3x
Answer:
the slope is 3
Step-by-step explanation:
Write the equation of each line in slope-intercept form and identify the slope. 4x=2+y
Answer:
y = 4x - 2
Step-by-step explanation:
Given: 4x=2+y
First, subtract 2 on both sides to isolate out y. (Slope-intercept form is y=mx+b)
Once subtracted, you get: 4x-2=y
Rearrange it, and you get: y=4x-2

A motor cyclist makes a trip of 500km. If he had increased his speed by 10kmh-1, he could have covered 600km in the same time. What was the original speed?
Answer:
the original speed is 50 km/h
Step-by-step explanation:
Let us assume the original speed be x
and fastest speed be (x+ 10)
Now here apply the time formula
i.e. distance by the speed
Original time = Fastest time
500 ÷ x = 600 ÷ x + 10
Now do cross multiplication
600x = 500(x + 10)
600x = 500x + 5000
100x = 5000
x = 50 km/h
Hence, the original speed is 50 km/h
A dinner at a restaurant was advertised at $60.00 plus 18%tax . The total bill for this dinner was.
Answer:
$70.80
Step-by-step explanation:
18%=0.18----Covert the percentage as a decimal
60*0.18=10.80----Multiply the dinner cost by the decimal as tax
$10.80+$60.00=$70.80----Add the last number and the price of the dinner to get your total of $70.80.

Step-by-step explanation:
[tex] {16y}^{2} + 40y + 25[/tex]
Step-by-step explanation:
(4y−5)^2+80y
Use binomial theorem (a−b)^2=a^2−2ab+b^2 to expand (4y−5)^2.
16y^2−40y+25+80y
Combine −40y and 80y to get 40y.

Step-by-step explanation:
5m+2v=18, 3m+8v=55
5m+2v=18
2v=18-5m
v=9-2.5m
plug (v=9-2.5m) in (3m+8v=55)
3m+8v=55
3m+8(9-2.5m)=55
3m+72-20=55
-17m=-17
m=1
plug (m=1) in (v=9-2.5m)
v=9-2.5m
v=9-2.5*1
v=6.5

Sargento cheese slices $2.48 for 10 slices or Velveeta cheese slices $3.18 for 12 slices find the unit rate for each and choose the better deal.
Answer:
Sargento cheese slices are the better deal
Sargento cheese slices $2.48 for 10 slices = 0.248 per slice
Velveeta cheese slices $3.18 for 12 slices = 0.265 per slice
Step-by-step explanation:
The unit rate for each cheese slice is $0.24 per piece for Sargento cheese slices and for Velveeta cheese slices is $0.26, and Sargento cheese slices is the better deal.
Given that,
Sargento cheese slices $2.48 for 10 slices or Velveeta cheese slices $3.18 for 12 slices.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
According to the question,
Sargento cheese slices, unit rate = 2.48/10 = $0.24
Velveeta cheese slices , unit rate = 3.18/12 = $0.26
From above Sargento cheese slices, is cheaper than Velveeta cheese slices.
Thus, the unit rate for each cheese slice is $0.24 per piece for Sargento cheese slices and for Velveeta cheese slices is $0.26, and Sargento cheese slices is the better deal.
