D
A, B, C and E are linear equations ( equations of straight lines )
y = 2x² - 1 is a parabola → not linear → D
36÷4=9
9×3=27
36-27=9
Fido=27
Rex=9
Answer:
Triangles congruent by ASA have two pairs of congruent sides and an included congruent angle. The graph indicates that sides TV, HG, and AB are congruent, and that sides TU, FG, and BC are congruent. It also indicates that angles U, F, and C are congruent, and that angles G and B are congruent.
Answer:
D. Infinitely many solutions
Step-by-step explanation:
1.Since neither equation contains an isolated. However, we can isolate -y in the first equation by adding to both sides.
Like this:
ending up with
2.Now, we can change y to a positive y. By doing so, we divide -y by the entire equation.
Like this
Ending with
3.Now, we can plug the expression into the second equation as a substitute for y, and solve for x. Then, we can use x to calculate y.
Like this
4. Since -2x+2x would cancel out and leave -30=-30. This is true because we know -30 equals -30 with no variable in sight.
Answer:
25.1 cm
Step-by-step explanation:
Ao what you have to do is use the equation, C=p*d. Plug in 3.14 for pi and then plug in 8 for the diameter. Leaving you with the answer 25.1 cm
