Answer:
c = 2
Step-by-step explanation:
2c – 4 = 3(4 – 2c)
Expand brackets:
⇒ 2c – 4 = 12 - 6c
Add 6c to both sides:
⇒ 8c – 4 = 12
Add 4 to both sides:
⇒ 8c = 16
Divide both sides by 8:
⇒ c = 2
Answer:
x-intercept: (-2, 0), y-intercept: (0, 10)
Step-by-step explanation:
First, we need to find the equation of this line. The formula to find the slope is:(y1-y2)/(x1-x2). Substituting the real numbers for this formula, (5-(-5))=10, (-1-(-3)=2. 10/2=5.
This means that the slope of this line is 5.
To find the complete equation for this line, we just need to plug in the x-value and add whatever needs to be added to attain the y-value. (You can plug in any x-value/y-value available.)
5=5(-1)+?
-5+<u>10</u>=5.
The complete equation for this line is y=5x+10.
From here, the y-intercept is easy, because the number after the coefficient and variable (5 and x) are before the y-intercept (in standard form). The <em><u>y-intercept is (0, 10)</u></em> because if you plug in 0 for the x-value, you will get 10 as your y-value.
On the other hand, if you plug in 0 for your y-value and solve it out, you will get the x-intercept.
0=5x+10
-10=5x
x=-2
So the <em><u>x-intercept is (-2, 0)</u></em>.
Answer:
-15b +7a
Step-by-step explanation:
Answer:
B. 1
Step-by-step explanation:
5x + 10 = 15
-10 -10
5x = 5
÷ 5 ÷ 5
x = 1
