The points in the table lie on a line. Find the slope of the line.

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.

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.

Answer:

264 with a remainder of 4

Step-by-step explanation:

The solution is: 44 is 268 divided by 6 with a remainder 4.

Here, we have,

given that,

268 divided by 6

Given the following mathematical expression;

268 /  6

We would apply the law of division for fractions.

268 /  6

= 268 ÷ 6

= 44 + 4

the remainder is 4

Hence, The solution is: 44 is 268 divided by 6 with a remainder 4.

Based on the given diagram, the length of FA is 51 units

Find the diagram attached. From the diagram;

AG = 2GF

Given that:

AG = 5x + 4

GF = 3x - 1

Substitute the given parameters into the formula;

5x + 4 = 2(3x - 1)

5x + 4 = 6x - 2

5x - 6x = -2 - 4

-x = -6

x = 6

Get the FA = 5x + 4 + 3x - 1

Substitute the value of x into the expression:

FA = 8x + 3

FA = 8(6) + 3

FA = 48 + 3

FA = 51 units

Hence the length of FA is 51 units

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

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.

Answer:

the value of x is 1......

as we know B is the midpoint....

y= [tex]\frac{2}{5}[/tex](x)+2

Step-by-step explanation:

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.
