If the given equations are y=3x+14 and y= -4x​. The value of x and y for the equation will be -2 and 8 respectively.

Equations are statements that affirm the equivalence of two expressions that are joined by the equals symbol "=". An equal sign ("=") links two expressions together to form an equation. The two expressions on each side of the equals sign are referred to as the "left-hand side" and "right-hand side" of the equation.

It is given that the equations are,

y=3x+14 ----------(1)

y= -4x​  -------------(2)

In order to solve "by substitution," you must first solve one of the equations for one of the variables (you choose which one), plug that solution back into the other equation, "substituting" for the selected variable and then solve for the other.

Substitute the value of y from equation 2 in equation 1 as

y=3x+14

-4x=3x+14

Rearrange the equation in order to find the value of x as

-4x-3x=14

-7x=14

x= -14/7

x= -2

Put the value of x in equation 2 as

y= -4x

y= -4(-2)

y=8

Thus, if the given equations are y=3x+14 and y= -4x​. The value of x and y for the equation will be -2 and 8 respectively.

Answer:

B. 66

Step-by-step explanation:

idk how to explain it without repeating what it says in the answer

Answer:

The answer is:

B) 66 degrees

Step-by-step explanation:

Since the triangle is an isosceles triangle, angle C is the same as angle B.

57 + 57 = 114

Since you know two of the three angles, and you know that a triangle's angles must equal 180 degrees...

180 - 114 = 66

Angle A must equal 66 degrees for the triangle to equal 180 degrees.

Q=17

Step-by-step explanation:

5q − 10 = 75

Add ten to both sides=5q=85

Divide both sides by 5=q=17

Answer:

A. 17

Step-by-step explanation:

Solve for q:

[tex] \longrightarrow[/tex] 5q - 10 = 75

Add 10 to both sides:

[tex] \longrightarrow[/tex] 5q + (10 - 10) = 10 + 75

10 - 10 = 0:

[tex] \longrightarrow[/tex] 5q = 75 + 10

75 + 10 = 85:

[tex] \longrightarrow[/tex] 5q = 85

Divide both sides of 5q = 85 by 5:

[tex] \longrightarrow[/tex] [tex] \sf \dfrac{5q}{5} = \dfrac{85}{5} [/tex]

[tex] \sf \dfrac{5}{5} [/tex] = 1:

[tex] \longrightarrow[/tex] q = [tex] \sf \dfrac{85}{5} [/tex]

[tex] \sf \dfrac{85}{5} [/tex] = 17:

Step-by-step explanation:

Given the algebraic equation of a line, we are able to graph it in a number of ways. In this section, we will be given a geometric description of a line and be asked to find the algebraic equation. Finding the equation of a line can be accomplished in a number of ways, the first of which makes use of slope-intercept form,  

y

Answer:

so if Thomas payed $40 for the bus we have to find what he payed not including the $40 bus fee.

so we have to subtract 40 from the total price of $104.40.

the equation is 104.40-40=?

104.40-40=$64.40 payed outside the bus fee.

now we have to figure out how many times .70 fits into 64.40

the equation would be 64.40/.70 which means we are dividing 64.40 by .70

so 64.40/.70=92

Answer:

[tex]\frac{30x+30}{x+7}[/tex] is the simplified radical expression.

Step-by-step explanation:

For this one, we have fractions in the bottom of a fraction (denominator).

So, we would multiply by [tex]\frac{1}{x+1}[/tex].

[tex]\frac{5x+5}{\frac{1}{6}x+\frac{7}{6} }[/tex]

Then Multiply by 6.

[tex]\frac{30x+30}{x+7}[/tex] is the simplified radical expression.

Answer:

20 minutes

Step-by-step explanation:

3 miles= 30 min

1 mile= 10 mins

2 miles= 10*2

2 miles= 20 min

It will take Stephanie 20 minutes to run 2 miles.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Stephanie ran 3 miles in 30 minutes.

Therefore, Stephanie ran 1 mile in (30/3) = 10 minutes.

Hence, It will take Stephanie (2×10) = 20 minutes to run 2 miles.

The slope is -2

Step-by-step explanation:

In any equation that is in the form of this question, the slope is always the number next to x. An example could be y = 6x - 1, the slope would be 6. If we had y = -100x - 5, the slope would be -100.

Answer:

Slope = -2

Step-by-step explanation:

x1   y1     x2   y2

(-1 , 9)     (2 , 3)

Slope = y2 - y1

             x2 - x1

3 - 9  = -6  

2 -(-1) =   3

                      = -2

The slope between the two points is -2.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The  slope is given as,

m = (d - b) / (c - a)

Where (a, b) and (c, d) are the two points.

Now,

(-1, 9) = (a, b) and (2, 3) = (c, d)

m = (3 - 9) / (2 + 1)

m = -6 / 3

m = -2

Thus,

The slope is -2.
