What is the equation, in point-slope form, of the line that is parallel to the given line and passes through the point (−3, 1)?
puteri [66]

Answer: The answer is (D) y-1=\dfrac{3}{2}(x+3).

Step-by-step explanation:  We are given to find the equation of a line which is parallel to the line in the graph and passing through the point (-3, 1).

The points (-2, -4) and (2, 2) lie on the line in the graph, so its slope will be

m=\dfrac{2+4}{2+2}=\dfrac{6}{4}=\dfrac{3}{2}.

The slope of the line parallel to the line in the graph will also be same. Since the new line passes through the point (-3, 1), so the equation of the line will be

y=1=m(x+3)\\\\\Rightarrow y-1=\dfrac{3}{2}(x+3),

which is in the slope-intercept form.

Thus, the correct option is (D).

By how much is the product of 9/5 and 8 1/4 greater than 5
Oliga [24]

Given:

The product of \dfrac{9}{5} and 8\dfrac{1}{4} greater than 5.

To find:

By how much the product of \dfrac{9}{5} and 8\dfrac{1}{4} greater than 5.

Solution:

First we need to find the product of \dfrac{9}{5} and 8\dfrac{1}{4}.

\text{Product}=\dfrac{9}{5}\times 8\dfrac{1}{4}

\text{Product}=\dfrac{9}{5}\times \dfrac{8(4)+1}{4}

\text{Product}=\dfrac{9}{5}\times \dfrac{33}{4}

\text{Product}=14.85

Now subtract 5 from the product.

14.85-5=9.85

Therefore, the product of \dfrac{9}{5} and 8\dfrac{1}{4} is 9.85 greater than 5.

How do you solve 125 - (5-9)^3÷2
hoa [83]
Solve what is in parenthesis first (5-9) = -4

Solve exponents next -4^3 = -64

Divide next
- 64 \div 2
= -32

Lastly, subtract and resolve the negatives which become a positive number 125 - (-32) = 125 + 32 = 157

Select the correct answer from the drop-down menu. Find the product. The product of 2/5a2x and -1/5x2a is
valentinak56 [21]

Answer: -\frac{2}{25}a^{3}x^{3}

Step-by-step explanation:

1. The problem asked for the product of \frac{2}{5}a^{2}x and -\frac{1}{5}x^{2}a, therefore, you must mutliply them, as you can see below:

2. According the exponents propertiess, when you have a multiplication of two powers that has the equal base, you must add the exponents. THerefore, you have the following result:

 (\frac{2}{5}a^{2}x)(-\frac{1}{5}x^{2}a)=-\frac{2}{25}a^{3}x^{3}
