Find k if the slope of 4y= -kx - 2 is 4.

oee [108]

Answer:

k = -16

Step-by-step explanation:

Given formula:

4y= -kx - 2, where slope is 4

Slope-intercept formula is:

y = mx + b, where m is the slope

Finding slope by bringing the formula to the same format as above:

4y = -kx - 2
y = -k/4x - 1/2

Slope is -k/4 and comparing it with the given:

-k/4 = 4
k = 4*(-4) = -16

3+(2+8)2ndpower ÷4×(1/2) 4th power

PIT_PIT [208]

Answer:

412

Step-by-step explanation:

You have to follow PEMDAS and solve the problem carefully.

$\frac{3+(2+8)^{2} }{4*(\frac{1}{2} )^{2} } =\frac{3+(10)^{2} }{4*(\frac{1}{2} )^{2} } = \frac{3+100}{4*(\frac{1}{2} )^{2} } = \frac{103 }{4*(\frac{1}{2} )^{2} }$

$\frac{103 }{4*(\frac{1}{2} )^{2} } = \frac{103 }{4*(\frac{1}{16})} } = \frac{103 }{\frac{1}{4} } =\\103*4\\=412$

José put $1,500 into a savings account. He earns 3% interest every year. How much simple interest will he earn at the end of 3 y

stiv31 [10]

He would have a total of: $1639.09

In intrest alone he would've made 1639.09

Step-by-step explanation:

3%= 0.03

The first thing you do is multiply $1,500 by the %3 (0.03).

When your done multiplying, you should get 45.

Add 45 to 1500

Now you have 1545

Then you repeat the process over, two more times. However the numbers will change.
