answer: y = 1.5x - 5.5
explanation:
use y = mx +b to model your equation
(m = slope, b = y-intercept)
let's start by finding slope
to find slope, subtract the y values over the x values.
- 4 - (-1) / - 5 - (-3)
solve and simplify.
-3 / -2
two negatives equals a positive, so convert into a decimal and remove the negative
you get 1.5.
now, plug the slope a y and x value into the equation to find b, the missing value.
-1 = 1.5(3) + b
-1 = 4.5 + b
-5.5= b
so, your equation is y = 1.5x - 5.5.
Answer:
Option C
Step-by-step explanation:
By applying cosine rule in the given triangle,
BC² = AB² + AC² - 2(AB)(AC)cosA
(11)² = 8² + 7² - 2(8)(7)cosx
121 = 64 + 49 - 112cos(x)
cos(x) = -
x =
x = 94.1°
Therefore, Option C will be the correct option.

y=2x+6
sub 2x+6 for y
3x-(2x+6)=6
3x-2x-6=6
x-6=6
add 6
x=12
sub
y=2x+6
y=2(12)+6
y=24+6
y=30
x=12
y=30
(x,y)
(12,30)
soltion is (12,30)
5 x 9 gives us the original area
= 45
When multiplied by 4:
(5x4)x(9x4)
20 x 36
= 720
720 divided by 45 = 16
The answer is D
Answer:
The 2 integers are 10 and 12
Step-by-step explanation:
Translate it into english
"The difference (some subtraction) of the squares of two positive consecutive integers ( and ) is (=) 44 (44)"
this means the following:
solve for x to find the smaller integer
first, expand
The 2 integers are 10 and 12
