What is the value of x in the equation: 0.7x - 1.4 = -3.5?A. -7
B. -3
C. 3
D. 7
Answers
Answer:
B). -3
add the -1.4 to-3.5 then divide the solution
Answer:
It's B. -3 (please mark as brainliest)
Step-by-step explanation:
0.7x−1.4=−3.5
Step 1: Add 1.4 to both sides.
0.7x−1.4+1.4=−3.5+1.4
0.7x=−2.1
Step 2: Divide both sides by 0.7.
0.7x
0.7
=
−2.1
0.7
So it's x=−3

Final answer:
The slope-intercept form of the given line, expressed in point-slope form as y - 4 = (x - 8), is y = x - 4. This indicates a slope of 1 and a y-intercept of -4.
Explanation:
The point-slope form of the equation of the line, y – 4 = (x – 8), illustrates a line passing through the point (8, 4) with a specific slope. The slope is the difference in the y-coordinates divided by the difference in the x-coordinates, as illustrated in the given figures.
In general, the equation of a straight line in slope-intercept form is given by y = mx + b, where m is the slope of the line and b is the y-intercept, i.e., the value of y when x is zero.
To convert the original equation into slope-intercept form, rearrange it by solving for y. First, rewrite the equation as y - 4 = x - 8, then add 4 to each side to isolate y:
y = x - 8 + 4
y = x - 4
So, the slope-intercept form of the equation for this line is y = x - 4, implying the line has a slope (m) of 1 and a y-intercept (b) of -4.

Answer:
x= -9.5
Step-by-step explanation:
We want to find out what the variable, x, is equal to. Therefore, we must isolate the variable on one side of the equation.
-4.75 = x/2
x is being divided by 2. The inverse of division is multiplication. Multiply both sides of the equation by 2.
2*(-4.75) = (x/2)*2
2*(-4.75)=x
2* -4.75=x
Multiply 2 and -4.75
-9.5=x
Let's check our solution. Plug -9.5 back in for x and solve.
-4.75= x/2
-4.75= -9.5/2
-4.75= -4.75
This checks out, so we know our solution is correct.
x is equal to -9.5

and the
saucer = S
then
(S + 3) + S = 12
2s + 3 = 12
2s = 9
s = 4.50
So by itself the saucer costs $4.50. To find the cost of the cup look to the beginning of the problem where we learned that
Cup = S + 3
cup = 4.50 + 3
cup = 7.50
So the saucer is $4.50 and the cup is $7.50...
4.50 + 7.50 = $12.00
It checks!
