Step-by-step explanation:
(-2,3) hope this helps
Answer:
Step-by-step explanation:
y=-2x-1
5y+3x=9, using y from above in this equation gives you
5(-2x-1)+3x=9
-10x-5+3x=9
-7x-5=9
-7x=14
x=-2, and since y=-2x-1
y=-2(-2)-1
y=4-1=3, so the solution is the point (-2,3)
x=-2 and y=3

Given p(x) = x+7/3
if p(x) = 13, find x.
Answers
Answer:
x = [tex]\frac{32}{3}[/tex]
Step-by-step explanation:
We know that p(x) = 13. Thus, substitute 13 for the "p(x)" in the equation. Then, isolate x by subtracting both sides by [tex]\frac{7}{3}[/tex]:
[tex]p(x) = x + \frac{7}{3}\\13 = x + \frac{7}{3} \\13 - \frac{7}{3} = x \\\frac{39}{3}- \frac{7}{3} = x \\\frac{32}{3} = x[/tex]
Thus, x = [tex]\frac{32}{3}[/tex].

Old MacDonald had a farm. On this farm he had some cows and chickens. When he “took stock” (counted), the farmer had 15 animals and 44 legs. How many cows and chickens did Old MacDonald have? PLS ANSWER
Answers
Answer:22
Step-by-step explanation:
Answer:
Step-by-step explanation:
let x be chickens and y be cows
x+y=15
x=15-y
2x+4y=44, using x=15-y
2(15-y)+4y=44
30-2y+4y=44
2y+30=44
2y=14
y=7, since x=15-y
x=8
So there are 8 chickens and 7 cows.

Graph representing the height of the plant will have y-intercept = b units
Since, the plant is growing at the same rate every week,
And growth of the plant is continuous.
Therefore, graph will be a straight line and continuous.
Since, the height of the plant is always increasing,
Slope of the line will be positive.
Option A will be the answer.
Maria is x old her sister is twice her age write an expression in simplest form that represents the sum of the ages of the two sisters
Answers
Answer:
x*2=y+x= both
Step-by-step explanation:
y would be her sister age, you would have to multiply Marias age by 2 to get her sisters age since her sister is twice her age then you have to add them together to get the sum of both their ages.
Example: maria is 16
16*2=32+16=48
so the sum of both of their ages is 48 (JUST AN EXAMPLE)

A circle has a diameter of 41 centimeters Which equation can be used to find the radius of this circle? 41 T= 2(41) T417
Answers
Answer:
If we are given diameter and we need to find radius then,
Radius(r) = Diameter(d) ÷ 2
⇒ r = d÷2
So here d = 41
So r = d÷2
⇒ r = 41 ÷ 2
⇒ r = 20.5
