A and B are points on a line that has the slope 2. The abscissa of B exceeds the abscissa of A by 3.5. State the relationship of
Troyanec [42]

Answer:

The ordinate of B exceeds the ordinate of A by 7

Step-by-step explanation:

Let

A(x1,y1),B(x2,y2)

where

x1 is the abscissa of A

x2 is the abscissa of B

y1 is the ordinate of A

y2 is the ordinate of B

we know that

m=\frac{y2-y1}{x2-x1}

m=2

so

2=\frac{y2-y1}{x2-x1}  -----> equation A

x2=x1+3.5 ----> equation B

substitute equation B in equation A

2=\frac{y2-y1}{x1+3.5-x1}  

2=\frac{y2-y1}{3.5}  

7=y2-y1  

y2=y1+7  

therefore

The ordinate of B exceeds the ordinate of A by 7

Find an equation of a line through √3,1 / 2) parallel to the line:
vagabundo [1.1K]

Answer:

(a) x=\sqrt{3}

(b) y=\frac{1}{2}

(c) Answer of part a is equation of line x=\sqrt{3} which is parallel to y axis and in part by equation of line is y=\frac{1}{2} which is parallel to x axis

Step-by-step explanation:

We have given points are (\sqrt{3},\frac{1}{2})

(a) Equation of line is given x = -9

We have to find the equation of line parallel to x= -9 and passing through (\sqrt{3},\frac{1}{2})

x = -9 line is parallel to y axis and so slope will be infinite

Equation of line is given by y-y_1=m(x-x_1)

So y-\frac{1}{2}=\frac{1}{0}(x-\sqrt{3})

x=\sqrt{3}

(b) Equation of line is given y=-\sqrt{7}

This line is parallel to x axis so slope will be zero

So equation of line will be y-\frac{1}{2}=0(x-\sqrt{3})

y=\frac{1}{2}

(c) Answer of part a is equation of line x=\sqrt{3} which is parallel to y axis and in part by equation of line is y=\frac{1}{2} which is parallel to x axis

Identify the property that justifies "x=y; if y=9, then x=9"
iragen [17]
I think the answer is substitution property of equality because you are substituting 9 for y as y=9.

PLEASE HELP ME <br><br> A<br><br> B<br><br> C<br><br> OR<br><br> D
RoseWind [281]

Answer:

Examine the mathematical expression you're working on. For example, suppose you're given 5x + 3. There are two terms here, 5x and 3. Look for the variable. In this case, x is the variable.  In your case its c

Find the numerical coefficient of x. Remember to look for the number before the variable. In this case, 5 is the numerical coefficient. The term 3 is a constant and is separated from the variable by a plus sign.

Keep an eye out for negative coefficients. For example, suppose you're given the statement -y + 7 + 98. You would first identify the variable, y.

Look for the numerical coefficient of y. In this case, a "1" is implied before the variable, but it's negative in this instance. Therefore, the coefficient of y is negative 1.
