Answer:

See attached

Step-by-step explanation:

[] Using this equation and the y-intercept (when x = 0) we can solve for the table, and then plot the points on the graph.

[] We know that when x is 0 y will be -1 because of the intercept.

-> Then we can plug the rest of the points in.

y = 4(-1) - 1

y = -4 - 1 = -5

y = 4(1) - 1

y = 4 - 1 = 3

y = 4(2) - 1

y = 8 - 1 = 7

[] Last, we can graph the points we just found.

Have a nice day!

For trapezoid JKLM, A and B are midpoints of the legs. Find AB.

romanna [79]

Answer:

Step-by-step explanation:

The length of the median of a trapezoid equals one-half the sum of the lengths of the bases.

$\begin{array}{rcl}AB & = & \frac{1}{2}(JK + LM)\\\\& = & \frac{1}{2}(19 + 39)\\\\& = & \frac{1}{2}\times 58\\\\& = & \mathbf{29}\\\end{array}$

I need help with this question.

TiliK225 [7]

Answer:

See below ~

Step-by-step explanation:

Let the bases be x and x + 6.

Substituting the known values into the formula :

A = 1/2 x (a + b) x h
48 = 1/2 x (x + x + 6) x 4
2x + 6 = 24
2x = 18
x = 9

The base lengths are :

x = 9 inches
x + 6 = 9 + 6 = 15 inches

Larry is considering taking out a loan. He estimates that he can afford monthly payments of $265 for 10 years in order to suppor

spayn [35]

Answer:

option-C

option-D

Step-by-step explanation:

we are given

He estimates that he can afford monthly payments of $265 for 10 years in order to support his loan

so, firstly we will find total amount

$A=265\times 12\times 10$

$A=31800$

now, we can verify each options

option-A:

r=6.6% =0.066

Amount is same

$A=31800$

now, we can use APR formula

$A=P(1+\frac{r}{n})^{nt}$

It is compounded monthly

so, n=12

we can plug it and then we can solve for P

$31800=P(1+\frac{0.066}{12})^{12\times 10}$

$P=16465.6215$

we can see that it is less than 24418.05

So, this is FALSE

option-B:

r=6.2% =0.062

Amount is same

$A=31800$

now, we can use APR formula

$A=P(1+\frac{r}{n})^{nt}$

It is compounded monthly

so, n=12

we can plug it and then we can solve for P

$31800=P(1+\frac{0.062}{12})^{12\times 10}$

$P=17133.96$

we can see that it is less than 24418.05

So, this is FALSE

option-C:

r=5.2% =0.052

Amount is same

$A=31800$

now, we can use APR formula

$A=P(1+\frac{r}{n})^{nt}$

It is compounded monthly

so, n=12

we can plug it and then we can solve for P

$31800=P(1+\frac{0.052}{12})^{12\times 10}$

$P=18927.00451$

we can see that it is less than 24418.05

So, this is TRUE

option-D:

r=5.8% =0.058

Amount is same

$A=31800$

now, we can use APR formula

$A=P(1+\frac{r}{n})^{nt}$

It is compounded monthly

so, n=12

we can plug it and then we can solve for P

$31800=P(1+\frac{0.058}{12})^{12\times 10}$

$P=17829.66$

we can see that it is less than 24418.05

So, this is TRUE
