The first equation in a system is 5x+2y=-4. Which equation gives a system with no solution.
Answers
Answer:
= 0.8 + -0.4y
Step-by-step explanation:
Simplifying
5x + 2y = 4
Solving
5x + 2y = 4
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
5x + 2y + -2y = 4 + -2y
Combine like terms: 2y + -2y = 0
5x + 0 = 4 + -2y
5x = 4 + -2y
Divide each side by '5'.
x = 0.8 + -0.4y

Considering that all quadrilaterals are squares. When x varies 1 unity, y varies 5 units. So the slope is 5.
Answer:
the answer is D
Step-by-step explanation:
slope=rise÷run
from point A to B 1 right and 5 up, so both are positive
rise is up or down

3(5+4y)+8-2y how to do this plz
Answers
Answer:
[tex]3\left(5+4y\right)+8-2y=10y+23[/tex]
Step-by-step explanation:
Given
As the expression is given by
[tex]3(5+4y)+8-2y[/tex]
To determine
Simplify the expression
Let us simplify the expression
[tex]3(5+4y)+8-2y[/tex]
Expand 3(5 + 4y) = 15 + 12y
[tex]3\left(5+4y\right)+8-2y=15+12y+8-2y[/tex]
grouping like terms
[tex]=12y-2y+15+8[/tex]
[tex]=10y+23[/tex]
Therefore,
[tex]3\left(5+4y\right)+8-2y=10y+23[/tex]

Determine the value of x for the following isosceles triangle.
Answers
Given :
▪︎This triangle is an isosceles triangle.
▪︎Measure of one of its legs = 6 inches
▪︎Measure of its equivalent leg [tex] = \tt \frac{x}{9} [/tex] inches
▪︎Measure of its base [tex] = \tt \frac{5}{2} [/tex] inches
Which means :
[tex] =\tt 6 = \frac{x}{9} [/tex]
[tex] =\tt \frac{6}{1} = \frac{x}{9} [/tex]
[tex] =\tt 6 \times 9 = x \times 1[/tex]
[tex]\hookrightarrow\color{plum}\tt 54 = x[/tex]
Let us check whether or not we have found out the correct value of x by placing 54 in the place of x :
[tex] =\tt 6 = \frac{54}{9} [/tex]
[tex] = \tt6 = 6[/tex]
Since the Left Hand Side of the equation is equivalent to the Right Hand Side of the equation, we can conclude that we have found out the correct value of x.
▪︎Therefore, the value of x = 54
