Answer:

4x^2 - 18x

Explanation:

Multiply 2x by 1x which should give you 2x^2 (squared because the x’s together would be squared), then multiply the 2x by 9 and you should be left with 18x which results in 4x^2 - 18x

What is the equation of the line with a slope of 3/4 that goes through the point (4, 1) in slope-intercept form?

Svetach [21]

Answer:

$y=\frac{3}{4}x+-2$

Step-by-step explanation:

We do not have enough information for slope intercept form. But we can use the point-slope formula to find the information. The formula is $y -y_{1} =m(x -x_{1})$ where we substitute a point (x,y) for $(x_{1},y_{1})$ .

We have m=3/4 and (4, 1). We input m and $x_{1} =4\\y_{1}=1$ .

$y-1=\frac{3}{4} (x-4)$

We now simplify the parenthesis and solve for y.

$y-1=\frac{3}{4} (x-4)\\y-1=\frac{3}{4}x+\frac{3}{4} (-4)$

We convert -4 into a fraction with 1 as the denominator.

$y-1=\frac{3}{4}x+\frac{3}{4} (\frac{-4}{1} )\\y-1=\frac{3}{4}x+\frac{-12}{4}\\y-1=\frac{3}{4}x+-3$

We add 1 to both sides to isolate y,

$y-1+1=\frac{3}{4}x+-3+1\\y=\frac{3}{4}x+-2$

This is slope intercept form. The line as slope 3/4 and y-intercept (0,2) or b=2.

Consider the following expression. 5(1+6) (2b+7) Select all of the true statements below.

Vesna [10]

Answer:

Option B
Option C
Option E

Explanation:

Option B is true because both of the terms are constants. Hence, they are like terms.
Option C is true because the coefficient of a term is basically the constant. If there is no constant, then the coefficient is 1.
Option E is true because the expression has been multiplied by 5.

Convince me why points B&C are solutions to this system of linear inequalities.

muminat

The coordinates of B and C are solutions to the system of inequalities because both are true to the two inequalities. A is not a solution to the system of inequalities because it is only true to “y is less than or equal to 2x”.

Whats the lcm of 8 and 10

Firdavs [7]

The answer is 40. Hope this helped! Between 8 and 10, you can determine the least common multiple by multiplying. 8*5=40, and 10*4=40.
