Answer: SO if you hv to solve for x then the answer is 4/13. And if you wanna solve for y then the answer is 4.
Step-by-step explanation: solve for x=
13x+y=4
13x+0=4
x=4/13
Solve for y=
13(0)+y=4
y=4
Answer:
f(3) = 45
Step-by-step explanation:
Substitute x = 3 into f(x) and evaluate
f(3) = 15 × 3 = 45
Make them all fractions over 4, so 3 would be 12/4, and 1 1/4 would be 5/4 so add them together
12/4+5/4= 17/4 then divide by 4 to reduce it, to get 4 1/4
First you get "y" by itself. To do so you divide 2 on both sides.
y = 3/2x + 5
To write an equation of a line that is PARALLEL to this equation, the slopes have to be the SAME. So the slope is 3/2.
You then use the equation:
y = mx + b
SInce you know "m" you plug it in.
y = 3/2x + b
Now you need to find b. To do so you plug in the point (2, -5) into this equation.
-5 = 3/2(2) + b
-5 = 3 + b
-8 = b
Finally you plug in b and you get your new equation.
y = 3/2x - 8
Answer:
See below
Step-by-step explanation:
If the whole rectangle were shaded (all 25 parts) that would be 100%
So, we can set up a proportion.
25 = 100%
11 = x
Then, cross-multiply to get,
25x = 1100
Divide both sides by 25 to solve for x
x = 44.
The x value represents the percentage shaded.
44%
