Simplify: -10 - 90x + 6x - 60

antoniya [11.8K]

Answer:

- 84x - 70

Step-by-step explanation:

We want to combine like terms:

-10 - 90x + 6x - 60

We can see (-10) and (-60) are both regular constants so:

- 10 - 60 = - 70

Then (-90x) and (+ 6x):

6x - 90x = - 84x

- 84x - 70

A line passes through the points (-1,-1) and (5,8) which points lie on the same line?

djverab [1.8K]

Answer: all points $(x,y)$ that satisfy $y=\frac{3}{2}x+\frac{1}{2}$

Step-by-step explanation:

The slope of the line is

$\frac{-1-8}{-1-5}=\frac{-9}{-6}=\frac{3}{2}$

So, substituting into point-slope form, the equation is

$y+1=\frac{3}{2}(x+1)\\\\y+1=\frac{3}{2}x+\frac{3}{2}\\\\y=\frac{3}{2}x+\frac{1}{2}$

Therefore, all points $(x,y)$ that satisfy $y=\frac{3}{2}x+\frac{1}{2}$ will lie on the same line.

Work out the value of 2. 4510 ×10to the power of 9 1.15 × 10 to the power of 3

Simora [160]

Answer:

The result in standard form is: $2.3 \times 10^{6}$

Step-by-step explanation:

Dividing the values:

To find the real part, we divide 2.645 by 1.15. So

2.645/1.15 = 2.3

Finding the power:

Its a division, so we keep the base, and subtract the exponents. So

$\frac{10^9}{10^3} = 10^{9-3} = 10^{6}$

Result in standard form:

The result in standard form is: $2.3 \times 10^{6}$
