7x^2+x+9 - (3x^2+4x-5)
= 7x^2 + x + 9 - 3x^2 - 4x + 5
= 4x^2 - 3x + 14

Solve y=5/8b + 10 for b

wolverine [178]

This is quite simply just rearranging for b.

$y= \frac{5}{8}b+10$

$y-10= \frac{5}{8} b$

$b = \frac{y-10}{\frac{5}{8}} = \frac{8(y-10)}{5} = \frac{8y-80}{5}$

Find the measure of the missing angles.

igomit [66]

Answer:

f = 26

d=112

e=42

Step-by-step explanation:

as far as what i can see, the first given angle is 112 and the second angle is 42.

These two angles are the angles on one straightline, therefore the missing angle will be 180 - 112 - 42 = 26 (Supplementary angle). This angle is not required and it is the missing angle on the left hand side. However, this angle should be equal to that of f (Opposite angle).

By the same way, d and e are the two opposite angles for 112 and 42, respectively.

Figure A is translated 3 units right and 2 units up. The translated figure is labeled figure B. Figure B is reflected over the x

Virty [35]

Answer:

A Is congruent to B and B Is congruent to C

Step-by-step explanation:

Let's look at the answer choices:

A: "A Is congruent to B and B Is congruent to C"

Well, clearly, if A ≅ B and B ≅ C, then by the transitive property, we can say that A ≅ C. So, A is very likely correct.

B: "A Is congruent to A, B Is congruent to B, C Is congruent to C"

Just because A is congruent to itself (and same with B and C) doesn't necessarily mean that they're congruent to each other. So, B is wrong.

C: "Each triangle is a right triangle."

Again, there are so many right triangles out there with different dimensions. For example, there are some with sides 3, 4, and 5, and others with sides 5, 12, and 13. They are not congruent, however. So, rule out C.

D: "Each triangle is an isosceles triangle."

This is just like choice C since there are so many variations of isosceles triangles. So D is wrong.

The answer is thus A.
