Answer:

Your correct, it's C and D

Step-by-step explanation:

A and E are right triangles, so that's not the answer. B and F are isosceles triangles so that's not the answer. C and D are 2 DIFFERENT obtuse triangles so that's why C and D are the answers.

Nostrana [21]

Answer:   y = 2x+22

========================================================

Explanation:

The equation y = 2x+5 is in the form y = mx+b

m = 2 = slope

b = 5 = y intercept

Parallel lines have equal slopes, but different y intercepts. So the answer will be in the form y = 2x+c, where b and c are different numbers. Since b = 5, this means c must be some other number. If c = 5, then we'd have the exact same line.

Let's plug in (x,y) = (-5,12), along with the slope m = 2, and solve for c

y = mx+c

12 = 2(-5)+c

12 = -10+c

12+10 = c

22 = c

c = 22

Since m = 2 and c = 22, we go from y = mx+c to y = 2x+22

The equation of the parallel line is y = 2x+22

The graph is below.

What is 155.78=2.95h+73.18<br> a. 28<br> b. 36<br> c. 3.6<br> d. none of these
xz_007 [3.2K]

Answer:

a. 28

Step-by-step explanation:

Given:

155.78=2.95h+73.18

We need to evaluate given expression to find the value of 'h'.

Solution:

155.78=2.95h+73.18

Now first we will apply Subtraction property of equality and subtract both side by 73.18 we get;

155.78-73.18=2.95h+73.18-73.18\\\\82.6=2.95h

Now we will use Division property of equality and divide both side by 2.95 we get;

\frac{82.6}{2.95}=\frac{2.95h}{2.95}\\\\h=28

Hence After evaluating given expression we get the value of 'h' as 28.
