Let x represent the cost of corn dogs. Let y represent the cost of pretzels.
2x+3y=13
5x+6y=28
Multiply the first equation by two so that we can eliminate y.
Subtract:
4x+6y=26
5x+6y=28
-x=-2
x=2
4(2)+6y=26
8+6y=26
6y=18
y=3
3 x 2 = 6
6+2=8
Therefore, 2 pretzels and a corn dog would cost $8.
Answer:
21 drawings
Step-by-step explanation:
So lets figure out how many drawings she can make per page. If she make a drawing using 1/3 of the page she can make 3 drawings per page. Now that we know she can make 3 drawings per padge, we can figure out how manyt drawings she can make by multiply the pages by drawings per padge. Let x be the drawings she can make.
7*3=x
Multiple 7*3
21=x
She can make 21 drawings
Answer:
2,2
Step-by-step explanation:
f(x)=(x-2)^2+2
=2,2
Answer:
B., E.
Step-by-step explanation:
what was the difficulty ? this is just to understand the movement of a thrown rock.
what happens, when you throw a rock through the air ? it will first move up a little bit, reaches a maximum height, and then drops down again.
that is what the graphic shows.
so, can A. be correct ? no. as we move from 0 seconds to the right (time passes) the height of the rock increases first (before decreasing again later on).
can C. be correct ? no, it would mean that the function would look the same on both sides of the x-axis. this is clearly impossible.
can D. be correct ? no, nowhere in the graph is the height (= the functional value, the y to the x) negative.
can F. be correct ? no, we clearly see the maximum height at 1.5 seconds. at 3 seconds the height is actually at its minimum.
Step-by-step explanation:
m<DAC is the exterior angle of the right angle triangle, where m<ACB and m<ABC are the interior angles of the triangle opposite to the exterior angle
Sum of the opposite interior angles is equal to the exterior angle
m<ACB+ m<ABC=m<DAC
a°+90°= 119°
a°=119-90°
a°=29°
