Can someone teach me how to do this im a good learner i just missed days

Answers

I’m not very good at explaining but if we explain from the beginning the equation is y=m(x)+b and m means the slope while b means y- intercept so all you have to do is substitute these variables with the numbers in the problem basically it would be y=10x+10 also the picture attached is how you graph it. Hope this helped:)

Ben wants to buy a new car stereo and he has already saved some money. He used this inequality to represent the amount he still has to save to be able to buy the stereo, where a represents the amount still left to save.

a + 212 greater-than-or-equal-to 365

If Ben saves $15 a week for the next 10 weeks, will he be able to buy the stereo and why?
No, because he needs to save at least $153, and he will only save $150 over the next ten weeks.
No, because he needs to save $577, and he will only save $150 more.
Yes, because he has already saved $365, and the stereo cost $212.

there is a certain number. If you add 30 7 to it, then subtract 22 7 from the previous result, and then subtract that difference from 59/7, after that you will get 19 7. What is a certain number?

Answers

Step-by-step explanation:

59 / 7 - ( x + 30 / 7 - 22 / 7 ) = 19 / 7

59 / 7 - ( x + 8 / 7 ) = 19 / 7

59 / 7 - x - 8 / 7 = 19 / 7

- x = 19 / 7 - 59 / 7 + 8 / 7

- x = - 32 / 7

x = 32 / 7

Answer:

∠KNC = 99°

Step-by-step explanation:

∠JNM + ∠KNC = 180    (it is a straight line)

∠KNC = 180 - ∠JNM

∠KNC = 180 - 81

∠KNC = 99°

Answer: 99°

Step-by-step explanation: They are supplementary so 180 - 81 = 99

Answer:

The required equation of the line is:

[tex]y=\frac{1}{4}x-1[/tex]

Step-by-step explanation:

Given the equation

[tex]y=-4x+3[/tex]

comparing the equation with the slope-intercept form

[tex]y=mx+b[/tex]

Here,

m is the slope y is the intercept

so the slope of the line is  -4.

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

The slope of the perpendicular line will be: 1/4

Therefore, the point-slope form of the equation of the perpendicular line that also intersects the point (8, 1) is:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-1=\frac{1}{4}\left(x-8\right)[/tex]

add 1 to both sides

[tex]y-1+1=\frac{1}{4}\left(x-8\right)+1[/tex]

[tex]y=\frac{1}{4}x-1[/tex]
