Answer:
X= -4
Step-by-step explanation:
Hello. For to solve that, you need to use the sustitution method:
1. You need clear X in the first equation and put in the second
X+Y = -10
X = -10-Y
2. Y = X-2, then you replaced the X in this equation:
Y = (-10-Y) - 2
Y+2=-10-Y
2Y=-10-2
2Y= -12
Y= -12/2
Y=-6
3. Now you use the Y value for to solve X:
X=-10-Y, then
X =- 10-(-6)
X = -4
write an equation for the line that passes through the given points (-2,9) And (1 ,-3)
Answer:
Finding slope: y2-y1/x2-x1
3-9/1+2
=-6/2
Divide 2 from both
=-3/1 or -3
Slope= -3
Finding y-intercept= y=mx+b
Choose any point on the line to plug in the x and the y then plug in the slope.
I choose (1,3)
3=-3×1+b
3=-3+b
Add 3 to both sides
6=b
Y-intercept=6
Equation: y=-3x+6

Use the expression to complete the statements. (0.5)10 (0.5)10 is the . (0.5) is the of (0.5)10. 10 is the of (0.5)10. A power is another way to write .
Question:
Use the expression to complete the statements.
[tex](0.5)^{10\\[/tex]
________ is the power .
(0.5) is the ________
A ______ is another way to write
Answer:
0.5 is the base
10 is the power
[tex](0.5)^{10\\ = (\frac{1}{2})^{10}[/tex] -- another way to write
Step-by-step explanation:
Given
[tex](0.5)^{10\\[/tex]
Required
Fill ion the gaps
[tex](0.5)^{10\\[/tex] is pronounced as; 0.5 raise to the power of 10
From the above statement, we can deduce the following:
0.5 is the base
10 is the power
Lastly, another way to write [tex](0.5)^{10\\[/tex]
Express 0.5 as a fraction
[tex](\frac{5}{10})^{10}[/tex]
Simplify the fraction
[tex](\frac{5/5}{10/5})^{10}[/tex]
[tex](\frac{1}{2})^{10}[/tex]
Hence:
[tex](0.5)^{10\\ = (\frac{1}{2})^{10}[/tex]

Find the value of x and the measure
Answer:
39°
Step-by-step explanation:
Complementary angles sum up to 90°
< JKL + < RST = 90
36 + x + 15 =90
51 + x = 90
x = 39°
2n + 3 = -3.2 what is the answer to n
Answer:n=-3.1
Step-by-step explanation:
2n + 3 = -3.2
Subtract 3 on both sides
2n+3-3=-3.2-3
2n=-6.2
Divide 2 on both sides
2n/2=-6.2/2
n=-3.1
Answer:
n= -3.1
Step-by-step explanation:

find the simple interest for having $2600 in the bank for 4 years the rate is 5%
Answer:
130 a year, so it would be $520 interest for 4 years in the bank.
Number the steps for balancing equations:
A gallon of gasoline cost $3.00 last year, and now costs 5% more. What is the cost of a gallon of gasoline now?
a) 4.50
b) 3.15
c) 3.05
Answer:
B
Step-by-step explanation:
We know that Last year one gallon costs $3.00
and we also know that it costs %5 more this year.
We know that %100 is always the same which is $3.00
Then since we know $3.00 is %100, we can add %5 to %100 to get %105.
Then you multiply 105/100 by 3 then you will get 3.15 which is what B is
So that means our answer is B

Answer:
radius: 4.2 cm
circumference: 26.376 cm^2
area: 55.3896 cm^2
Step-by-step explanation:
radius is half the diameter so 8.4/2 = 4.2
circumference: C = (2)(pi)(r) ---> (2)(3.14)(4.2) --> 26.376
area: (pi)(r ^2) --> (3.14)(4.2^2) --> 55.3896

Explain how to find vertical and horizontal asymptotes of a rational
equation.
Answer:
Step-by-step explanation: If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0).
If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.
Write the unit fraction depicted in the model as a percent.
One-fourth
Answer:
As
1/4×100 = 0.25×100
= 25%
Thus,
1/4 = 25%
Step-by-step explanation:
Given the fraction
1/4
In order to write the fraction 1/4 as a percent, all we need is to multiply 1/4 by 100.i.e.
1/4×100 = 0.25×100
= 25%
Therefore, we conclude that:
1/4 = 25%
