Answer:
y = -1x - 3
Step-by-step explanation:
y = mx + b
m = slope = -1
b = y-intercept = -3
Plug in
y = -1x - 3
Answer:
y = -x - 1
Step-by-step explanation:
Slope - Intercept form is y = mx + b
m = slope
b = y-intercept
We already have the slope of -1. Substitute it into the equation.
y = -x + b
To find b, substitute the given point (2, -3) into the equation.
-3 = -2 + b
b = -1
Substitute the value of b into the equation and you are left with:
y = -x - 1
-9 (c + 7) = -13c +7
What value of c makes the equation true? Enter the answer in the box.
Answer:
c=17,5Step-by-step explanation:
-9(c+7) = -13c+7
<=> -9c - 63 = -13c+7
<=> -9c + 13c = 7+63
<=> 4c = 70
<=> c = 70/4 = 35/2 = 17,5
CHECK THE ANSWER:-9(c+7) = -13c+7
-9(17,5+7) = -13×17,5+7
-220,5 = -220,5

Brand A cereal contains 10 cups of cereal.Brand B cereal has 30 percent more cereal in the box than brand A.How many more cups of cereal are in Brand B cereal
Answer:
3
Step-by-step explanation:
if B has 30% more than A then 1.3 multiplied by 10= 13
so B contains 13 cups
13-10 is how many more B has than A
so the answer is 3
Which of these figures have lines of symmetry? If so, how many?
Answer:
1, 4, 0

Find the area of the rectangle and the triangle independently. What is the ratio comparing the area of the triangle to the area of the rectangle? (Must be in Reduced Form)
Answer:
hello your question is incomplete attached below is the complete question
answer : 2
Step-by-step explanation:
Area of rectangle = [tex](\frac{b}{h}) (\frac{h}{2})[/tex]
Area of triangle = [tex]\frac{1}{2}bh[/tex]
therefore the ratio of the area of the triangle to the area of the rectangle
= [tex]\frac{\frac{1}{2} bh}{\frac{b}{2}*\frac{h}{2} }[/tex] = 2

In 1998, Journeys sold 15 million pairs of Vans across the
U.S. In 2008, Journeys sold 45 million pairs of Vans. What
was the average rate of change in shoe sales for the store?
Answer:
3 million/yearStep-by-step explanation:
Average rate of change is the slope in same interval:
(45 million - 15 million)/(2008 - 1998) years=30 million / 10 years =3 million/yearIn 1998, Journeys sold 15 million pairs of Vans.
In 2008, Journeys sold 45 million pairs of Vans.
To Find:The average rate of change in show sales for the store.
Formula:Final year : 2008
Initial year : 1998
Final sale : 45 million
Initial sale : 15 million
Average sales = Final sale - Initial sale / Final year - Initial year
Explanation:Average sales = 45 million - 15 million / 2008 - 1998
Average sales = 30 million / 10 years
Average sales = 3 million / 1 year
Answer:The average rate of change in show sales for the store is 3 million per year.

for every 15 students who run track there are 7 students who play baseball there are 112 more students who run track than play basball
Answer:
How many students run TRACK? 210
How many students play BASEBALL? 98
15*14= 210 and 7*14 = 98, 210 - 98 = 112
Answer:
There are 210 students who run track and 98 students who play baseball.
Step-by-step explanation:
15x= Students who run track
7x= Students who play baseball
15x - 7x = 112 (*combine like terms)
8x = 112 (*divide 112 by 8)
X = 14 (*now plug X into both equations stated earlier)
15x = 15 x 14 = 210 (Number of students who run track
7x = 7 x 14 = 98 (Number of students who play baseball)
