Answer:

The sum given is not reasonable.  

Step-by-step explanation:

Given : Jill added 450+790+123 and 1163.

To find : Is this sum reasonable? Explain.

Solution :

To find the correct result we have to add them step by step,

4 5 0

7 9 0

+1 2 3

-----------

13 6 3

So, 450+790+123=1363

The sum given is not reasonable.

Therefore, The given sum is not correct.

Let us manually add the given numbers.

450

790

123

____

1363 

 

Therefore we see that the correct answer 1363 which is far from what Jill got which is only 1163.

Therefore the answer is No, the sum should be 1363 (closer to 1400).

What equation is the inverse of y=2x^2-8?
Fynjy0 [20]

Step-by-step explanation:

To get the inverse, swap the x- and y-variables, then solve for y. We should have the equation: x = 2y^2 - 8

Solving for y:    

y = 2x^{2} - 8    because  y + 8 = 2x^{2} or  x =\sqrt\frac{y +  8}{2}

So on interchanging the variable, we get the equation:

x = 2y^2 - 8

x + 8 = 2y^2

y = \sqrt\frac{x + 8}{2}

The equation for line g can be written as y = 2/9x + 10.
valina [46]

Answer:

y=2/9x-1/3

Step-by-step explanation:

since line h is parallel to line g, this means that line h has the same slope as line g.

line h's slope would be 2/9.

to find the y-intercept, plug (-3, -1) into the equation y=2/9x+b. -3 will represent x and -1 will represent y:

y=2/9x+b

-1=2/9(-3)+b

Then, solve for b:

-1=2/9(-3)+b

-1=-6/9+b

b=-1/3

so, the equation for line g is: y=2/9x-1/3

Consider the diagram below.<br> Which of the following statements is correct?
Nutka1998 [239]

Answer:

A

Step-by-step explanation:

The diagram shows two parallel lines XY and WV.

1. Parallel lines XY and WV are cut by transversal XW, then angles YXZ and VWZ are congruent as alternate interior angles.

2. Parallel lines XY and WV are cut by transversal YV, then angles XYZ and WVZ are congruent as alternate interior angles.

AA similarity theorem states if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

So, \triangle XYZ\sim \triangle WVZ by AA similarity

Alika [10]

Answer:

The percentage change each year is 2%

Step-by-step explanation:

Generally, we can have an exponential equation written as;

f(t) = I( 1 + r)^t

where f(t) is the value at a certain time

I is the initial value at t = 0

r is the growth rate

t is the time we are looking at

Thus, we have it that;

1.02 = 1 + r

r = 1.02 -1

r = 0.02

So, let us write 0.02 as a percentage

We have this as 2/100 which is the same as 2%

The percentage change each year is 2%
