The value of x from the expression is 2

<h3>Expression and equation </h3>

Given the expression

2x = 74/2 - 37

We are to calculate the value of x from the expression

2x = 37 - 37

Since 37 - 37 = 0

2x = 0

Divide both sides by 2:

2x/2 = 0/2

x = 0

Hence the value of x from the expression is 2

What is the equation of a line with a slope of 7 and a point (1, 8) on the line?

Helen [10]

Answer:

$y=7x+1$

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

In this problem we have

$m=7$

$point(1,8)$

substitute and solve for b

$8=7(1)+b$

$8=7+b$

$b=8-7=1$

The equation of the line is equal to

$y=7x+1$

If a spherical ball is enlarged so that its surface area is 9 times greater than its original surface area, then the original ra

luda_lava [24]

The surface area of a sphere is $A = 4 \pi r^{2}$ and if the original S.A was is enlarged to have it 9 times greater, the radius would be multiplied by 3 or roughly 2.99626 rounded off to 3.0.

For example, let us assign values.
Let A=90

A= 90*9 = 810

$90 = 4 \pi r^{2} 

$ and $810 = 4 \pi r ^{2}$

the first r is 2.68 and the second r is 8.03

then, $\frac{8.03}{2.68} = 2.99626$ or rounded off to 3.

PLEASE HELP I'm having trouble

Anastasy [175]

Answer:

$c_{11}=56.1$

$c_{12}=12.1$

$c_{13}=236$

Step-by-step explanation:

The product of two matrices $X_{m\times{n}}$ and $Y_{n\times{r}}$ equals a matrix $M_{m\times{r}}$ , where the first element of the subscript represents the amount of files of the matrix and the second element represents the amount of columns of the matrix.
Then, in this case $A_{1\times{3}}$ $B_{3\times{3}}$ , therefore, its product will result a matrix $C_{1\times{3}}$ .
Because C matrix is going to have an only file and three columns, we now have to find the values of the elements in each column, based on the elements of A and B.
Commonly, to obtain the values of the resulting matrix, we just have to multiply each file of the first matrix by each column of the second matrix and sum, as follows:

$c_{11}=77\times1.2+39\times2.2-33\times3.7=56.1$
$c_{12}=77\times1.4+39\times1.1-33\times4.2=12.1$
$c_{13}=77\times3.1+39\times5.6-33\times6.7=236$

Finally, C matrix is $\begin{pmatrix}\56.1 & 12.1& 236\end{pmatrix}$
