Answer:
i cant see picture sorry
Step-by-step explanation:
Answer:
Any line can be graphed using two points. Select two x x values, and plug them into the equation to find the corresponding y y values.
Step-by-step explanation:
Look at the picture.
Domain: -4 ≤ x ≤ 4
Range: -1 ≤ y ≤ 1
<h3>Answer: {x | -4 ≤ x ≤ 4}</h3>
Answer:
x = 7
y = 0
Step-by-step explanation:
→To solve this, you can use the elimination method. To do this, you must have one set of variables that can cancel each other out. In the problem given, we already have positive 4x and -4x, making them cancel out:
4x + 9y = 28
-4x - y = -28
__________
8y = 0
y = 0
<u>→Plug in 0 for y, into an equation:</u>
-4x - 0 = -28
-4x = -28
x = 7
Answer:
none of the 3 choices are 70 % shaded
Step-by-step explanation:
→the first choice has 100% divided in 5 so each part is 100/5 = 20 %
shaded is 20%+20%+20%+20% = 80%
→the second one has 100% divided in 4 parts so each part is 100/4 = 25%
shaded is 25%+25%+25% = 75%
→ the third choice has 100% divided in 10 parts so each part is 100/10 = 10%
the shaded area is 10%+10%+10% = 30%
none of the 3 areas are 70 % shaded
