Answer: 41
Explanation: Use the equation. If you put the x value, which is 5, into the equation, you can solve.
4(5)+21
4 x 5 is 20
20+21=41
hope this helps!!
Answer:
C
Step-by-step explanation:
The vertex form of the equation of a circle is
where (h,k) is the center of the circle and r is the radius. This means that for the circle with center (-3,1) and radius 5 substitute into the vertex form these values. Substitute h = -3, k= 1, and r = 5. The equation becomes
. This simplifies to
. The solution is C.
Answer:
12
Step-by-step explanation:
idk but please just mark me brainliest
5p-4p-8=-2+3
Combine like terms
p-8= 1
Add 8 to both sides to isolate p
p=9
Final answer: 1 solution only, p=9
Answer:
Red line
Step-by-step explanation:
2y+x=0
2y=-x
y=-x/2
Put the equation into y=mx+b so you would need to subtract the x to put it on the right side so then you’ll have 2y=-x+0 then divide by 2 to get the y by itself then you’ll have y=-2x+0 that means the line would be negative and the y-intercept is 0 and the only line that follows that is the red line.
