Mathematics

iren [92.7K]3 years ago
4 0

Answer:

Step-by-step explanation:

3x + 4y = 8

 

4y = 8 - 3x

 

y = 2 - (3/4)x

 

So the slope of the given line is -(3/4).

Answer as quickly as possible​
Alenkasestr [34]

Answer:

6. If the x intercept is a then (a,0) is on the line. If y-intercept is b then (0,b) is on the line. Now you have two points of the line and can get its formula. The slope between thse points is m=(0−b)(a−0)=−b/a. So the equation of line is y=mx+b=−bx/a+b. Now rearrange as y+bx/a=b divide by b to get y/b+x/a=1

Sadly I can't get eight right now but once I do I will edit this.

Melanie's room measures 10 ft by 12 ft. Her rug covers 90 ft². Explain how to determine the percent of floor covered by the rug.
Inessa [10]

\huge \bf༆ Answer ༄

Here's the solution ~

Area of floor is ;

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:10 \times 12

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:120 \: ft {}^{2}

Area covered by rug is ;

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:90 \: ft {}^{2}

So, the percentage of floor covered by rug is ~

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: \dfrac{90}{120}  \times 100

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: \dfrac{3}{4}   \times 100

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:3 \times 25

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:75  \%

For the function y = -10x find the matching y-value when x = 3​
Alchen [17]

Answer:

y= -30

Step-by-step explanation:

THis is because you substitue 3  for X and then multiply -10 and 3 and a negative times a positive is a negative so -10 times 3 is -30
