Answer:
x=−175 and y=−1220
Step-by-step explanation:
Based on the Vertical Angles Theorem, -7x+5=y
Since we know that 2 angles that form a line when combined equal 180 degrees, we know that (4-12x)+y=180
-7x+5=y
(4-12x)+y=180
Now we solve the system:
7x+5=y;−8x+y=180
First, we solve 7x+5=y for y:
7x+5+(−y)=y+(−y)
7x−y+5=0
7x−y+5+ (−5)=0+ (−5)
7x−y=−5
7x−y+(−7x)=−5+(−7x)
−y=−7x−5
-y/-1=(-7x-5)/-1
y=7x+5
Now we will substitute 7x+5 for y in the other equation:
−8x+y=180
−8x+7x+5=180
−x+5=180
−x+5+(−5)=180+(−5)
−x=175
-x/-1 = 175/-1
x=−175
Finally, we'll substitute -175 for x in y=7x+5:
y=7x+5
y=(7)(−175)+5
y=−1220

It rained all day on Father's Day and the temperature dropped ten and seven tenth degrees. The next day the rain
stopped and the temperature rose twelve and six tenths degrees. If the temperature at the beginning of Father's Day
was sixty five and eight tenths degrees, what was the temperature at the end of the day after Father's Day?

Answer:
67.7
Step-by-step explanation:
Temperature at beginning of Father's Day = 65.8 degrees
Drop in temperature because of rain = 10.7 degrees
Rise in temperature after the rain the next day = 12.6 degrees
Therefore, temperature at the end of the day after the Father's Day
= Temperature at beginning of Father's Day minus Drop in temperature because of rain plus Rise in temperature after the rain the next day
= 65.8 - 10.7 + 12.6
= 67.7 degrees
NB: The answer was written as only 67.7 as requested by the questioner.
The graph of the function f is shown, f(5)=
Answer: -1 and 5
Step-by-step explanation:
You see you know in f(x) that become f(5) that means x=5 so in the graph you have to find the line of the x ( it is written) and then just see where the the curve is “ cutting” the graduation 5 of the line of the x . Sorry if you don’t understand, have an amazing rest of you day :)

Michaela rode her bike on 14 2/3 mile trail. She stopped every 3 1/5 miles for a drink of water . Issac and Jake estimated how many times Michaela stopped.
Answer/Step-by-step explanation:
The rail = [tex] 14\frac{2}{3} miles [/tex]
She stops after every [tex] 3\frac{1}{5}miles [/tex] for a drink.
The number of times she stopped for a drink = [tex] \frac{14\frac{2}{3}}{3\frac{1}{5}} [/tex]
Change the fractions to improper fractions
[tex] \frac{\frac{44}{3}}{\frac{16}{5}} [/tex]
Change the division operation to multiplication, and then flip the fraction on your right upside down.
[tex] \frac{44}{3} \times \frac{5}{16} [/tex]
[tex] \frac{44 \times 5}{3 \times 16} [/tex]
[tex] \frac{220}{48} = 4.58 [/tex]
If we approximate this to the nearest whole number, we would have an estimate of 5.
✅Therefore, we can conclude that Michaela stopped 5 times.
The estimate given by Issac and Jake is omitted in the question. However, the person who got an estimate of 5 is the person who made a better estimate.

Answer:
y=1/5x + 8/5
Step-by-step explanation:
First you take the reciprocal of -5 which is -1/5.
Then you substitute the values to find the b.
1= -1/5(-3) +b
1=3/5+b
Add 3/5 to both sides
1+3/5= 5/5+3/5
b=8/5
Which graph best represents a line with a slope of
?
Answer:
A. y = -2/3 + 3
Step-by-step explanation:
the line intercept the y axis at +3
and the slope is: -2/3
- i used coordinates (3,1) and (6,-1)
Answer:
y = [tex]\frac{-2}{3}x + 3[/tex]
Step-by-step explanation:
Take any two points
(x₁, y₁) = ( 3 , 1 ) & (x₂ , y₂) = (6 , -1)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]=\frac{-1-1}{6-3}\\\\=\frac{-2}{3}[/tex]
m = (-2/3) & (x₁, y₁) = ( 3 , 1 )
y - y₁ = m(x - x₁)
y - 1 = [tex]\frac{-2}{3}(x - 3)[/tex]
y - 1 = [tex]\frac{-2}{3}x - 3 *\frac{-2}{3}[/tex]
y - 1 = [tex]\frac{-2}{3}x + 2[/tex]
y = [tex]\frac{-2}{3}x + 2 + 1[/tex]
y =[tex]\frac{-2}{3}x[/tex] + 3
Write an equation of a line in slope intercept form that is parallel to y = -3x+9 and passes through the point (-2,-5)
