Answer:
If your question is -2 - 4 - 2 - 2.1 then the answer is -10.1
Step-by-step explanation:
-2 - 4 - 2 - 2.1
= (-2 - 4 ) - 2 - 2.1 Combine -2 with -4 or subtract them
= -6 - 2 - 2.1
= (-6 - 2 )- 2.1 Combine -6 and -2
= -8 -2.1 Combine -8 and -2.1
= -10.1

Answer:
y = 8x + 7
Explanation:
The equation of the line in slope-intercept form has the following general formula:
y = mx + c
where:
m is the slope of the line = 8
c is the y-intercept = 7
Substitute with the givens in the above formula to get the slope of the line as follows:
y = mx + c
y = 8x + 7
Hope this helps :)
Y = mx + b
Where m is the slope and b is the y-intercept
As you can already see it passes through the origin so b (the y-intercept) is (x, 0)
And the slope were it’s rise/run so it goes up 2.5 units and to the right 1 unit so it’s 2.5/1 = 2.5
m = 2.5
Answer:
x=8.499
y=0.167
Step-by-step explanation:
the equation says:x^2-9y^2=72....(1)
x+3y=9.......(2)
divide (2) from (1),it becomes:
x-3y=8
making x subject of formula,
x=8+3y....(3)
submitting (3) into (1),it becomes
(8+3y)^2-9y^2=72
64+48y=72
48y=72-64=8
y=8/48=0.167......(4)
submitting (4) into (2),it becomes
x+3(0.167)=9
x+0.501=9
x=9-0.501
x=8.499
