If a + b = -6 and x + y + z = -2, what is 8a - 7x - 7z - 7y + 8b

Mathematics
1 answer:
Oxana [17]3 years ago

Answer:

-34

Step-by-step explanation:

a + b = -6

x + y + z = -2

We want 8a so multiply the first equation by 8

8( a + b) = -6*8

8a+8b = -48

We also want -7x so multiply the second equation by -7

-7(x + y + z) = -2*-7

-7x-7y-7z = 14

Add the two equations together

8a+8b = -48

-7x-7y-7z = 14

-------------------------

8a+8b-7x-7y-7z = -34

Rearranging the order

8a - 7x - 7z - 7y + 8b = -34

alukav5142 [94]

A(14)=240(1+0.09)^14-1

A(14)=240(1.09)^13

A(14)=240(3.065)

A(14)=735.79

meriva

Answer:

Triangular Prism

Step-by-step explanation:

Given

The sketch in the attached diagram

Required

Determine the shape it represents

Analyzing the options 1 after the other

Triangular Prism:

This has 5 sides; 2 of which are triangles while the other are rectangles

Rectangular Prism

This, in other words represents a cuboid

Triangular Pyramid

This has 4 sides, all of which are triangles

Rectangular Pyramid

This has 5 sides; 4 of which are triangles while the last is a square of rectangle.

From the analysis above, the best option that answers the question is The Triangular Prism because it perfectly describes Lucia's drawing

An equation of the line that passes through the given point and is parallel to the graph of the given equation
notsponge [240]

To construct the equations for these lines, we are going to use the point-slope formula, which is:

(y - y_1) = m(x - x_1)

  • m is the slope of the line
  • (x_1, y_1) is a point on the line

1)

In this case, our point is (2, -1) and our line has a slope of 5. (Remember that the line is parallel, meaning that it has the same slope as the given line. Since the line is in the y = mx + b format, we could easily pick out the slope m as being 5.)

Thus, we can "plug in" what we know into our formula to find the equation of our line:

(y + 1) = 5(x - 2)

(y + 1) = 5x - 10

y = 5x - 11


2)

We are going to do the same thing, except our point is now (0, -5) and our slope is now 9.

(y + 5) = 9(x - 0)

y = 9x - 5


Our equations are:

1) y = 5x - 11

2) y = 9x - 5

Lloyd solves the equation 24x + 18(x – 2) = 216 for x. Some of his steps are shown.
Elena-2011 [213]

Answer:

Hi there!

Your answer is:

To get from step 3 to step 4, Lloyd added 36 to both sides. On the left side, this equaled 0 due to the additive inverse property! (-36 + 36 = 0!) On the right side, 36 is added to 216! (216+36 = 252)
