Answer:
Multiply the second equation by 2
Step-by-step explanation:
If you do that you will get 2y in the first equation and -2y in the second equation. then, you can add the 2 equations to get rid of y.
Answer:
2
Step-by-step explanation:
For elimination problems, you have to have the variables that you want to cancel out equal in value but opposite in sign.
Since you are trying to cancel out y and you are changing the second equation, look at the first equation.
The y variable is +2y. This means that the second equation with a y variable of -2y.
Since the the second equation's y variable is -y, multiply it by 2.
-y x 2 = -2y
Why do tangent function have vertical asymptotes at the same places a cosine function crosses the x axis
Answer:
The asymptotes for the graph of the tangent function are vertical lines that occur regularly, each of them π, or 180 degrees, apart. They separate each piece of the tangent curve, or each complete cycle from the next. is because those points are where the cosine function is equal to 0

A local hamburger shop sold a combined total of 773 hamburgers and cheeseburgers on Sunday. There were 73 more cheeseburgers sold than hamburgers. How many hamburgers were sold on Sunday?
Answer: There were 350 hamburgers sold.
Step-by-step explanation:
x + (x +73)= 773 where x is the number of hamburgers sold and (x+ 73) is the number of cheese burgers sold.
x + (x+ 73)=773
2x + 73 = 773
2x + 700
x= 350
1(350)= 350
Matching quantities with units
Answer:
1. Volume = length x width x height => cubic centimetres.
2. Perimeter = 2(length) + 2(width) => metres.
3. Speed = Distance /time => metres per second.
4. Area = length x width => square metres.
Step-by-step explanation:
1. Volume = length x width x height
If the length, width and height are measured in centimetre (cm) , then, the unit of the volume will be:
Volume = cm x cm xcm = cm3 i.e cubic centimetres.
2. Perimeter = 2(length) + 2(width)
If the length and width are measured in meter (m), then, the unit of the perimeter will also be in metre (m).
3. Speed = Distance /time
If the unit of distance is measured in metre (m) and the time is measured in second (s), then , the unit of the speed will be:
Speed = Distance /time = m/s i.e metres per second.
4. Area = length x width
If the length and width are measured in metres (m), then, the unit of the area will be:
Area = m x m = m2 i.e square metres

Find all the angles of the triangle.
A straight line is 180° therefore you do 180°-105°=75°
All the angles in the triangle added together is 180°.
Now you write it into an equation,
55+75+x=180
x=180-130
x=50°

If you're good at logarithms please help me with question two d and h thanks
show full working out ;)
Answer:
d. -0.301
h. 1.38
Step-by-step explanation:
Loga0.5 = loga2^-1
= -1(loga2)
= -1 (0.301)
= -0.301
Loga24 = loga(2^3 x 3)
= loga2^3 + loga3
= 3 (loga2) + loga3
= 3 (0.301) + (0.477)
= 1.38

Eureka math grade 7 module 6 lesson 23 problem set
Answer:
What Do You MeanStep-by-step explanation:
find the missing letter which is n. perimeter is 108 inches and width is 18 inches
The perimeter can be found by using the formula: P = 2w + 2h
w = width
h = height
P = perimeter
We are given the perimeter of 108 inches.
We are given the width of 18 inches.
Substitute in the formula.
108 = 2(18) + 2h
108 = 36 + 2h
Solve for h.
108 = 36 + 2h
108 - 36 = 36 - 36 + 2h
72 = 2h
72/2 = 2h/2
36 = h
Therefore, the length of the missing side is 36 inches.
Best of Luck!

If the zeros of a quadratic functions are -2 and 4, which graph could represent the function?
Answer:
The Graph having the X-intercepts of (-2,0) and (4,0)
Step-by-step explanation:
The zeroes of the function is the X-intercept.
The graph that represent the function should be that it contains the x-intercept of (-2,0) and (4,0)
What is x-intercept?
Here the x-intercept means the x-coordinate of the point at which the line, curve, the surface should be intersected at the x-axis.
Since there are the zeros of the quadratic equation that contains -2 and 4
So here we can say that The graph that represent the function should be that it contains the x-intercept of (-2,0) and (4,0)

Answer:
[tex]36\ \text{gallons per unit}[/tex] will flow from the hose in 45 minutes.
Step-by-step explanation:
The line of best fit for the scatter plot can be described by the equation :
[tex]y=\dfrac{4}{5}x[/tex]
y is amount of water in gallons
x is time
When x = 45 minutes, put x = 45 in above formula as :
