Answer:

If one −5s−7(8s−1): -61s+7

If two −5s−7(8s−1): -112s+14

Step-by-step explanation:

-5s-7(8s-1)

Multiply -7 onto 8s and -1:

-5s-56s+7

add -5s and -56s:

-61s+7

−5s−7(8s−1)−5s−7(8s−1)

Multiply both -7 to 8s and -1

-5s-56s+7-5s-56s+7

add:

-112s+14

The sum of two numbers is 19. Three times the larger is 3 more than 6 times the smaller. Find the numbers.
ella [17]

Answer:

x=6

y=13

Step-by-step explanation:

The statement says that:

3x=6y+3\\

Been y the smaller and x the larger. The other equation that we have is the summation of the two numbers. Then we have 2 equations and 2  unknowns

1. 3x=6y+3\\2. x+y=19\\

Solving the equations the answers is x=13 and y=6.

Draw a line through the origin that has a slope of 4/3
Ket [755]

Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>

In this problem the given line represent a proportional relationship, because passes through the origin

we have

k=\frac{4}{3} --->  the constant of proportionality k is equal to the slope

substitute

The linear equation is

y=\frac{4}{3}x

To draw a line we need two points

we have (0,0)

To find the other point

assume  x=3 and substitute in the equation to solve for y

y=\frac{4}{3}(3)=4

so

The other point is (3,4)

using a graphing tool

Plot the points (0,0) and (3,4)

To graph the line join the points

see the attached figure

If you guys can answer this then please help
s344n2d4d5 [400]

Answer:

64°

Step-by-step explanation:

First, we have to find the angle situated in R, the addition of all angles in a triangle is 180° so that means:

x + 68 + 48 = 180

x = 180-116 = 64°

Now, remember that this angle (64°) is the same as this one = ?, thanks to one property.

So basically, that angle has the same value as that one.

? = 64°

Hope it was helpful ;)

Given the triangle below, answer the following:
OLEGan [10]

Answer:

Step-by-step explanation:

question no . 5

ratio of angle L

take angle as reference angle

using cos rule

cos L = base / hypotenuse

= 4/5

ratio of angle N

take angle N as reference angle

using sin rule

sin N = opposite / hypotenuse

= 4/5

for measure of angle L

cos L = 4/5

cos L = 0.8

L = cos^{-1}(0.8)

L = 36.9

for meanure of angle N

sin N = 4/5

sin N = 0.8

N = sin^{-1}(0.8)

N = 53.1
