What must be added to 1,316 to make 5

Ratling [72]

Answer:

-1311

Step-by-step explanation:

1316 + x = 5

Subtract 1316 from both sides:

1316 - 1316 + x = 5 - 1316

On the left side they cancel out and we are left with:

x = 5 - 1316

Which simplifies to:

x = -1311

What is the slope of the line shown in the graph? <br> A.-3/2<br> B.-1/2<br> C.3/2

Varvara68 [4.7K]

I think answer is A
Because slope=rise/run
Rise is 3
Run is 2
But it will be negative because of the direction of slope

the line y=2x-4 is dilated bt a scale factor of 3/2 and centered at the origin. Write an equation that represent that image of t

Veseljchak [2.6K]

Answer: $y = 2x -6$

Step-by-step explanation:

Since, If (x,y) represents the coordinates of a line, then after dilation about the origin by the scale factor k, the coordinates of the resultant line will get by the rule,

$(x,y)\rightarrow (kx,ky)$

Here, The equation of the given line is,

y = 2x - 4

x-intercept and y-intercept of the line are (2,0) and (0,-4) respectively,

Hence, the line y = 2x - 4 will be passes through the points (2,0) and (0,-4),

By the above property,

The dilated line about the origin will be passes through the points (3,0) and (0,-6), ( Because (3/2× 2, 3/2×0) = (3,0) and (3/2×0, 3/2×-4) = (0,-6) )

Hence, the equation of transformed line after dilation,

$y-0 = \frac{-6-0}{0-3}(x-3)$
