What is the value of m in the equation 38(m−29)=434 ?

Len [333]

38(m - 29) = 434...distribute thru the parenthesis
38m - 1102 = 434...add 1102 to both sides
38m = 434 + 1102
38m = 1536....divide both sides by 38
m = 1536/38
m = 768/19 or 40 8/19

3. 'a' and 'b' are the intercepts made

Julli [10]

Given:

'a' and 'b' are the intercepts made by a straight-line with the co- ordinate axes.

3a = b and the line pass through the point (1, 3).

To find:

The equation of the line.

Solution:

The intercept form of a line is

$\dfrac{x}{a}+\dfrac{y}{b}=1$ ...(i)

where, a is x-intercept and b is y-intercept.

We have, 3a=b.

$\dfrac{x}{a}+\dfrac{y}{3a}=1$ ...(ii)

The line pass through the point (1, 3). So, putting x=1 and y=3, we get

$\dfrac{1}{a}+\dfrac{3}{3a}=1$

$\dfrac{1}{a}+\dfrac{1}{a}=1$

$\dfrac{2}{a}=1$

Multiply both sides by a.

$2=a$

The value of a is 2. So, x-intercept is 2.

Putting a=2 in $b=3a$ , we get

$b=3(2)$

$b=6$

The value of b is 6. So, y-intercept is 6.

Putting a=2 and b=6 in (i), we get

$\dfrac{x}{2}+\dfrac{y}{6}=1$

Therefore, the equation of the required line in intercept form is $\dfrac{x}{2}+\dfrac{y}{6}=1$ .

Rina draws a plan of her school on a coordinate grid. She plots the school gate at point p(-8,-1) and the library at point Q(2,5

natka813 [3]

Answer:

The coordinates of the science lab is:

x = -14/3 , y = 1

Step-by-step explanation:

∵ P is (-8 , -1) and Q is (2 , 5)

∵ The point of the science lab is (x , y)

∵ The science lab point divided PQ at ratio 2 : 1 from Q (two thirds PQ)

∴ $x=\frac{m_{1}x_{p}+m_{2}x_{q}}{m_{1}+m_{2}}$

∴ $y=\frac{m_{1}y_{p}+m_{2}y_{q}}{m_{1}+m_{2}}$

∴ $x=\frac{2(-8)+1(2)}{1+2}=\frac{-14}{3}$

∴ $y=\frac{2(-1)+1(5)}{2+1}=\frac{3}{3}=1$

∴ The point of science lab = (-14/3 , 1)

vladimir2022 [97]

Answer:

A, B, C

Step-by-step explanation:

A = -8

B = |-6| = 6

C = |11| = 11

Least to greatest, negatives are the least and between 6 and 11, 11 is the greatest.
