Find the value of the variable.

Answer:

(x+y)(a+b)-(y+z)(a+b)

first we solve half

(x+y)(a+b)

(xa+xb+ya+yb)

(y+z)(a+b)

(ya+yb+za+zb)

(xa+xb+ya+yb)-(ya+yb+za+zb)

xa+xb+ya+yb-ya-yb-za-zb

which needs to cut

+ya-ya+yb-yb

now left

xa+xb-za-zb

-90 = -100+x

-90+100=X

+10 =X

OPTION B:- 10

Option B :- 10

Explanation :

[tex] - 90 = - 100 + x \\ - x = - 100 + 90 \\ - x = - 10 \\ x = 10 \\ [/tex]

Step-by-step explanation:

Let's write the equation with formula:- Where, x1 is -1 and y1 is 4 and m is 3Thus, The correct choice is option C.

Step-by-step explanation:

Equation of line formula=> y=mx+c

Let take point (-1,4) as (x, y) and slope m=3

4= 3(-1) +c

4= -3+c

4+3=c

7=c

Therefore by using equation of line formula we get

y= mx+c [m=3 , c=7]

y=3x+7

3x² - 14x + 8 = 0

Δ = (-14)² - 4*3*8 = 196 - 96 = 100 = 10²

2 solutions

x' = (14 + 10) / (2*3) = 24 : 6 = 4

x" = (14 - 10) / (2*3) =4/6 = 2/3

3 (x - 4) (x - 2/3) = 0

Answer:

3.949

Step-by-step explanation:

We can use the formula to find the error bound:

EBM=(zα/2)(σn/√)

We know that σ=7 and n=17. We are also given that the confidence level (CL) is 98%, or 0.98. So, we can calculate alpha (α).

α=1−CL

=1−0.98

=0.02

Since α=0.02, we know that

α2=0.022=0.01

The value of z0.01 is 2.326. Now we can substitute the values into the formula to find the error bound.

EBM=(zα/2)(σ/√n)

=(2.326)(7/√17)

≈(2.326)(1.698)

≈3.949

So, the error bound (EBM) is 3.949.

Answer:

191.25 mm

Step-by-step explanation:

area of triangle is 1/2 b*h

1/2 (7.5*15) = 56.25

area of rectangle is b*h

15*9 = 135

56.25+135 = 191.25

Answer:

  34.5 square meters

Step-by-step explanation:

We assume you want to find the area of the shaded region. (The actual question is not visible here.)

The area of the triangle (including the rectangle) is given by the formula ...

  A = 1/2bh

The figure shows the base of the triangle is 11 m, and the height is 1+5+3 = 9 m. So, the triangle area is ...

  A = (1/2)(11 m)(9 m) = 49.5 m^2

The rectangle area is the product of its length and width:

  A = LW

The figure shows the rectangle is 5 m high and 3 m wide, so its area is ...

  A = (5 m)(3 m) = 15 m^2

The shaded area is the difference between the triangle area and the rectangle area:

  shaded area = 49.5 m^2 - 15 m^2 = 34.5 m^2

The shaded region has an area of 34.5 square meters.

Answer: y=8x-7 just took the quiz hope that helps

The other equation could be y = 8x - 7

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

to determine the other equation:

The first equation is given as:

y = 8x + 7

For the system of equation to have no solution, then the equations in the system would have different constant values.

Take for instance:

y = 8x + b

Where:

b is a constant not equal to 7

From the options, we have:

y = 8x - 7

Notice that -7 and 7 are not the same

Hence, the other equation could be y = 8x - 7

Answer: 402.12 cubic inches

Step-by-step explanation:

Formula for volume of a cylinder: area of base x height

Area of base: pi x radius squared

So, pi x 4 squared

= 50.27

50.27 x 8 = 402.12

Using proportions, it is found that they had traveled 245 miles when Jack fell asleep.

A proportion is a fraction of a total amount.

Jack slept through the last 65% of the trip, hence he fell asleep when 100 - 65 = 35% of the 700 mile trip had been traveled, so:

0.35 x 700 = 245.

They had traveled 245 miles when Jack fell asleep.

Answer: 2/10

Step-by-step explanation:

Multiply each X value by the probability it happens. This gives 0(10/10)+1(2/10)=2/10

Answer:

let us consider on inequality. Seven is greater than two on number that says one every month. Supply one with a positive intention on both sides. A tree. Then this will change. Toe three multiplied with seven is greater than three months. Playing with stool, which will give us that 21 is greater than six status. There is no change in the direction of inequality. Now I'm multiplying. The first inequality picked a negative intention on both sides and minus tree. So then this inequality will change. Toe minus string multiplied with seven is greater than minus street multiplied. Which two, which will become the don'ts that we'll get, will be minus 21 on dhe minus six according to the first inequality. If the direction it's saying the little Belgian as mine is strange even is greater than minus six, which is not possible, so the direction will get automatically reversed. On this, inequality will become minus 21 which is less than minus six. It doesn't eat for violent of the first inequality, so therefore we have seeing that Ben be multiplied the inequality by a postive intrusion on both sides. Then the direction off inequality stays the same. On the other hand, when they're multiplying both sides with a negative Indonesia, then the direction off the inequality will become reverse. So this is what is known as the multiplication property. Oh, the inequalities.
