The equation that would best describe the situation would be the first option. To solve this question, simply break down the question into sections and then use variables X and y to represent each of the things asked for in the problem. We know the following:

X = no of tetra fish
Y = no of goldfish
If there is twice as much goldfish than tetra fish, then it would be 2y.

X = 2Y.

Then knowing what X and y represent, find the equation that gives the total cost of fish he bought, knowing that 1.50 is for a goldfish and 2.00 is for a tetra fish.

Ms. Cassidy instructed Miguel to change one sign of the graph of y < 2x – 4 so that point (2, 3) can be included in the solution set.

To check which of the given options might Miguel write we check the inequality that holds true for the point (2,3).Substituting x=2 ,y=3 we have:

1) y < 2x – 1

3<2(2)-1

3<3  Not True.

2)y ≤ 2x – 4

3≤ 2(2) -4

3≤ 0  .Not true.

3) y > 2x – 4

3> 2(2)-4

3> 0   True.

4) y < 2x + 4

3<2(2)+4

3<8   True

5) .y < 3.5x – 4

3< 3.5(2)-4

3<3  Not true

6) y < 4x – 4

3<4(2)-4

3<4   True.

Options 3 ,4 ,6 holds true for the point (2,3)

What’s the measure of X in this short answers are fine
miv72 [106K]

Answer:

28 = x

Step-by-step explanation:

62 =  angle BAC  since they are vertical angles

angle ABC is a right angle since KL is perpendicular to FG

Adding the angles in triangle ABC

BAC + ABC + BCA = 180

62 + 90 + BCA = 180

152 + BCA = 180

BCA = 180-152

BCA = 28

BCA = x since they are vertical angles

28 = x
