<h3>Answer: Point D</h3>

See the diagram below. I drew a line through the left corner points of the red and blue quadrilaterals. This line goes through the point D. You could pick on the right corners of the original quadrilaterals and that line will also pass through point D.

The equation that could be used to solve for x is (3x-1) = 140 and the value of x is 47°.

According to the question,

We have the following information:

We have two lines that are intersecting each other at a point. The angles made on this point are given.

Now, we know that these two angles are vertically opposite angles. And we also know that vertically opposite angles are equal.

So, we will have the following equation:

3x-1 = 140

Now, we can easily find the value of x from this equation:

Adding 1 on both sides of the equation:

3x = 140+1

3x = 141

Dividing by 3 on both sides:

x = 141/3

x = 47°

Hence, the equation that could be used to solve for x is (3x-1) = 140 and the value of x is 47°.

Find the equation for the trend line through the points (0, 11) and (100, 33). Then use it to predict the number of baskets Romy

sleet_krkn [62]

Answer:

28 baskets

Step-by-step explanation:

The equation for a linear trend line is given by:

y = mx + b, where y and x are variables, m is the slope of the line and b is the y intercept (that is value of y when x is zero).

The equation of a line passing through two points $(x_1,y_1)\ and\ (x_2,y_2)$ is:

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

y represent the number of baskets made and x represents the time take. Given that the line passes through the points (0, 11) and (100, 33), hence:

$y-11=\frac{33-11}{100-0}(x-0)\\\\y-11=\frac{11}{50}x\\\\y= \frac{11}{50}x+11$

The number of baskets Romy would make after practicing for 80 minutes (x = 80) is:

$y=\frac{11}{50}x+11\\\\y=\frac{11}{50}(80)+11 \\\\y=17.6+11\\\\y=28.6\\\\Therefore\ y\ =\ 28\ baskets$

Factor this polynomial completely x2 + 3x – 18 A. (x-2)(x + 9) B. (x+3)(x-6) оо C. (x - 3)(x+6) D. (x - 3)(x-6)

Umnica [9.8K]

Answer:

C. $(x-3)(x+6)$

Step-by-step explanation:

I think the equation meant $x^2+3x-18$ ?

Anyways, to factor these kinds of quadratic, keep into consideration:

$ax^2+bx+c=(x+w)(x+v)$

ONLY if:

$w+v=b\\wv=c$

Start off by finding factors of c, which in this case, -18:

±(1, 2, 3, 6, 9, 18)

If one of the numbers is negative then the other number must be positive.

Find which two factors will sum up to b, which in this case, is 3.

$1+(-18)\neq 3\\2+(-9)\neq 3\\3+(-6)\neq 3\\6+(-3)=3\\9+(-2)\neq 3\\18+(-1)\neq 3\\$

The only two factors that work are 6 and -3.

Replace them into the factored form:

$(x+w)(x+v)\\(x+6)(x-3)\\(x-3)(x+6)$
