Answer:
y =
x + 11
Step-by-step explanation:
The equation of a straight line is: y = mx+c where m is the slope of the line and c is the y-intercept of a line.
Slope =
= 
= 
=
To find the y-intercept, we can use one of the points to apply for the equation before finding the y-intercept. I will be using the point (4,14).
y =
x + c
14 =
×4 + c
14 = 2
+ c
c = 14-2
c = 11
Thus, the y-intercept is 11

The answers are - 5x+8y and 5(4)+2(8)=36
Explanation
To solve the equation, you would substitute x and y for 5 and 8.
-Ex: 5(4)+8(2)=36
The numbers in the parentheses get multiplied by the numbers on the outside. Making ‘5(4)’=20 and ‘8(2)’=16
So 5(4)+8(2)=36
To simplify the expression stated, it is better to write it in the numerical form. The statement is:
<span>quantity 12 x plus 36 over quantity x squared minus 4 x minus 21
The numerical form is:
12x+36 / (x</span>²-4x-21)
Simplifying,
12x+36 / (x<span>²-4x-21)
</span>12 (x+3) / (x+3)(x-7)
We can cancel the x+3 term, leaving only:
12/(x-<span>7)</span>
Do 15 percent divided by 60k multiplied by 4
Answer:
m∠y=41
m∠x=90
Step-by-step explanation:
It is an isosceles triangle, so m∠B=49 too
49+49=98
180-98=82
82÷2=41
m∠y=41
41+49=90
180-90=90
m∠x=90
