How do i solve 2x=-3
i need answer ASAP
Answer:
[tex]x = \frac{-3}{2} \\or \\x = -\frac{3}{2}\\or\\-1.5[/tex]
Step-by-step explanation:
2x = -3
divide 2 from both sides
[tex]x = \frac{-3}{2} \\\\or \\x = -\frac{3}{2}[/tex]
Answer:
x=-1.5
Step-by-step explanation:
1. Divide on both sides to get the x alone; -3 divided by 2 is -.15 or -3/2

Slope 5, passing through (-4,1)
Answer:
y=5x+21
Step-by-step explanation:
right now we know y=5x+b, so all we need is b.
graphing it on paper starting at (-4,1), you can go up 5, right 1 because your slope is 5.
you'll get (-4,1) (-3,6) (-2,11) (-1,16) (0,21)
Once you reach x=0, your intecept is 21, completing the slope intercept form, making it y=5x+21.

you recieve a pay raise of 5% then recieve a pay cut of 5%. after the two changes in pay your salary is unchanged
Answer:
true
Step-by-step explanation:
False, receive a pay raise of 5% then receive a pay cut of 5%. after the two changes in pay, your salary is changed.
Given that,
To justify the given statement is false or true.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
here,
let the salary be x,
Salary after 5% raise = 1.05x
Salary after cut of 5% = [1 - 0.05] [1.05x]
Salary after a cut of 5% = 0.9975x
So the salary becomes 99.75% of the original salary x.
Thus, the given statement is false, receive a pay raise of 5% then receive a pay cut of 5%. after the two changes in pay, your salary is changed.

Dad's age is equal to the sum of Laura's, Jeri's and Theresa's ages. If Jeri is 4 years older
than Theresa and 3 years younger than Laura, and Dad's age is 38, how old is each
daughter?
Answer:
Jeri is 13, and thus Theresa is 9 and Laura is 16.
Step-by-step explanation:
Let's start by declaring variables
D - dad's age
L - laura's age
J - jeri's age
T - theresa's age
The first statement tells us that D = L + J + T
Jeri being 4 years older than Theresa gives us
J = T + 4
Jeri being 3 years younger than Laura gives us
J = L - 3
So notice that the common variable in these two equations is J. So if we can represent every girls age in terms of Jeri's, we will be down to one variable. So
T = J - 4
L = J + 3
Now, we can rewrite the original equation using only J's
38 = (J + 3) + J + (J - 4)
38 = 3J - 1
39 = 3J
13 = J
So Jeri is 13, and thus Theresa is 9 and Laura is 16.
The graph below could be the graph of which exponential function
Answer:
A
Step-by-step explanation:
The graph below could be the graph of A) F(x) = 2*[tex](0.7)^x[/tex] exponential function.
The graph of the function F(x) = 2 * [tex](0.7)^x[/tex] is a decreasing exponential function. This is because the base of the exponent, 0.7, is between 0 and 1. As x increases, the value of [tex](0.7)^x[/tex] decreases, so the value of F(x) decreases.
The graphs of the other functions are all increasing exponential functions. This is because the bases of the exponents, 2, 5, and 1.4, are all greater than 1. As x increases, the value of [tex]2^x[/tex], [tex]5^x[/tex], and [tex]1.4^x[/tex] increases, so the value of the functions F(x) = 2 * [tex]2^x[/tex], F(x) = 2 * [tex]5^x[/tex], and F(x) = 2 * [tex]1.4^x[/tex] increases.
Therefore, the graph of the function F(x) = 2 * [tex](0.7)^x[/tex] is the only graph that is decreasing. So the answer is A.
Here is a table that summarizes the properties of the graphs of the four functions:
Function Base of the exponent Graph
F(x) = 2 * [tex](0.7)^x[/tex] 0.7 (between 0 and 1) Decreasing
F(x) = [tex]2^x[/tex] 2 (greater than 1) Increasing
F(x) = 2 * [tex]5^x[/tex] 5 (greater than 1) Increasing
F(x) = 2 * [tex]1.4^x[/tex] 1.4 (greater than 1) Increasing

Given that f ( x ) = 3 x − 7 and g ( x ) = 3 x + 9 , evaluate f ( g ( 2 ) )
Answer:
38
Step-by-step explanation:
f ( x ) = 3 x − 7
g ( x ) = 3 x + 9
f(g(2))
First find g(2)
g(2) = 3(2)+9 = 6+9 = 15
Then find f(15)
f(15) = 3*15 -7 = 45 -7 =38

Answer:
y= [tex]\frac{2}{5}[/tex](x)+2
Step-by-step explanation:
First take two points from the line (x-int (-5,0) and y-int (0,2)). Once you get that you want to find the slope using the formula [tex]\frac{Y_{2} -Y_{1} }{X_{2}- x_{1} }[/tex]. Substitute the values and find the slope. Once you find the slope (m) to be [tex]\frac{2}{5}[/tex], take any of the two points and apply it to the slope intercept formula (y=mx+b) to find b. I took the point (0,2) and applied it to the formula. It should look like 2= [tex]\frac{2}{5}[/tex](0)+b. Solve for b by multiplying 2/5 by zero and your left with 2=b. Plugin the missing varibles for the equation and it should come out to be y= [tex]\frac{2}{5}[/tex](x)+2.

Find the diagram attached. From the diagram;
AG = 2GF
Given that:
AG = 5x + 4
GF = 3x - 1
Substitute the given parameters into the formula;
