Answer:
x = 9
Step-by-step explanation:
2(x + 5) = 3x + 1
open the parenthesis
2x + 10 = 3x + 1
subtract 2x from both sides of the equation
2x - 2x + 10 = 3x - 2x + 1
10 = x + 1
subtract 1 from both sides of the equation
9 = x
Answer:
Step-by-step explanation:
Substitute
2x+10=3x+1
Subtract 3x to other side
-x+10=1
Subtract 10
-x=-9
divide -1 both sides
x= 9

Write an equation in point slope form that passes through (-14, - 6) and the
slope is 2/3
Answer:
y=2/3x - 6
Step-by-step explanation:
use the formula y=mx+b. the m of this equation is equal to the slope and you know that the slope is 2/3. the b of the equation is equal to the y-intercept so, to find b you simply look at the points given. the points are written in (x,y) form so if -14 is x, -6 must be y. remember to KEEP CHANGE CHANGE your signs so that plus sign becomes negative 6. Hope this helps!

Answer:
196 meters
Step-by-step explanation:
It would be 196 meters below or the lowest point would be the bottom. If it asks for feet do the conversion rate.
Answer:
-281
Step-by-step explanation:
–85–196 = – 85+(– 196) = –281

Mia says that when you rearrange 3a - p = m to make a the subject of the formula you get:
a = m - p / 3
Mia is wrong. Explain and show her how to do the
question correctly.
Answer:
[tex]a =\frac{m+p}{3}[/tex]
Step-by-step explanation:
[tex]3a - p = m[/tex]
→ First plus p to both sides to isolate 3a
[tex]3a = m+p[/tex]
→ Divide both sides by 3 to isolate a
[tex]a =\frac{m+p}{3}[/tex]
Answer:
see explanation
Step-by-step explanation:
Mia is wrong in that she has subtracted p from both sides instead of adding p to both sides.
Given
3a - p = m ( add p to both sides )
3a = m + p ( isolate a by dividing both sides by 3 )
a = [tex]\frac{m+p}{3}[/tex]

Answer:
A. 1.88
Step-by-step explanation:
In less fancy terms, a constant of proportionality is essentially a rate of change - or more specifically, a unit rate.
It's the number we multiply our independent variable by to get the y. You can find this by simply dividing the y value by the x value!
Let's choose the first order pair (2, 3.76).
[tex]3.76 \div 2 = 1.88[/tex]
We can check that this table IS constant by doing the same with the other values... we should always get 1.88!
[tex]7.52 \div 4 = 1.88\\9.40 \div 5 = 1.88\\15.04 \div 8 = 1.88[/tex]
This is true for all values - which means our constant is 1.88

what is the domain of the function s=-4r^2 if the range is s <_ 0
Answer:
r≤0
Step-by-step explanation:
if the range is s≤0, (that means the value of s is all negative integers &0) to find the domain we have to replace that some negative integers &0.
we can replace some values of s as the following
s=‒4(0)^2 s=‒4(‒1)^2
=‒4(0) =‒4(1)
=0 =‒4
s=‒4(‒2)^2 s=‒4(‒3)^2
=‒4(4) =‒4(9)
=‒16 =‒36
so we can understand easly that the domain is negative integer&0,it can't be positive because the square of any integer is positive.
therefore the answer is r≤0
i think &i hope it is clear.
The domain is the set of values for which the given function is defined. The domain of the function s=-4r² if the range is s≤0 is r∈R. The correct option is B.
What are the domain and range of a function?The domain is the set of values for which the given function is defined.The range is the set of all values which the given function can output.For the given function s=-4r², the domain of the function when s≤0 will be all the real numbers. This is because, for any value of r whether it is positive or negative, the value of r² will be positive, but at the same time this quantity is needed to be multiplied by -4.
Thus, the result of -4r² will be always negative, which is less than zero.
Hence, the domain of the function s=-4r² if the range is s ≤0 is r∈R.

5+ 2/3×= -x+20. This is equations with variables in both sides pls help fast I'll mark as brainliest
Answer:
x = 9
Step-by-step explanation:
5+ 2/3x= -x+20.
Add x to each side
5+ 2/3x +x= -x+x+20
5 + 2/3x+3/3x = 20
5 + 5/3x = 20
Subtract 5 from each side
5+5/3x -5 = 20-5
5/3x = 15
Multiply each side by 3/5
3/5 * 5/3x = 15*3/5
x = 9
Answer:
Step-by-step explanation: 5+2/3x= -x+20

Simplify 4/7 / 3 over negative 8
Answer:
(4/7)÷ (3/-8). Division of fractions is the same as multiplying their reciprocals. So (4/7) x (-8/3). Now multiply the numerators together and denominators together (make sure you only use the negative sign once). (4 x -8) / (7 x 3) = -32/21.
