Answer:
x = -2.3
Step-by-step explanation:
4x + 1.3 = -7.9
First we want to combine the like terms.
Subtract 1.3 from both sides.
4x = -9.2
Now we want to isolate x by dividing both sides by 4.
x = -2.3
Check your answer by plugging x back into the original equation.
4x + 1.3 = -7.9
4(-2.3) + 1.3 = -7.9
Multiply.
-9.2 + 1.3 = -7.9
Add.
-7.9 = -7/9
Your answer is correct.
Hope this helps!

plug it into a calculator. its taking 7 away from an already negative number.
Answer:
Therefore,
Step-by-step explanation:
Given:
GF = 12
GE = 16
DF = 12
CF = v
To Find:
v = ?
Solution:
In Δ GFC and Δ GED
∠ E ≅ ∠ F …………..{ measure of each angle is 90° given }
∠ G ≅ ∠ G ……….....{Reflexive Property}
Δ GFC ~ Δ GED ….{Angle-Angle Similarity test}
If two triangles are similar then their sides are in proportion.
On substituting the given values we get
Therefore,
Neither.
Parallel lines have the same slope.
Perpendicular lines have negative reciprocal slopes.
Rewriting the 2nd equation to solve for y,
You get:
Y=1/5x + 1/2
The first equation slope is negative, and the second is positive. However, the second slope is 1/5, and not 5/1 - which would be the negative reciprocal of (-1/5)from the first equation.
Hope that helps!
Answer:
-5/3
Step-by-step explanation:
To solve for slope we use the slope formula which is y2-y1/x2-x1.
For this problem I chose the points: (-5,10) and (-2,5)
-5 is x1, 10 is y1, -2 is x2 and 5 is y2
We now plug in the points into the slope formula:
5-10/-2-(-5)= -5/3
