Answer:

B) 15/(9+(-9))

Step-by-step explanation:

Be careful of the parentheses because if you just write out 15/9+(-9),

it's technically, saying that 15/9+(-9)=5/3+(-9)=5/3-9, and that's different from what you want to express, mathematically.

Given △MON≅△PQR with MO=20 , MN=32 and PR=3x−10. Find the value of x.<br><br> show your work

aliya0001 [1]

Answer:

$x=14$

Step-by-step explanation:

we know that

If two figures are congruent, then its corresponding sides and its corresponding angles are congruent

In this problem

△MON≅△PQR

corresponding sides

MO≅PQ

MN≅PR

ON≅QR

corresponding angles

∠M≅∠P

∠O≅∠Q

∠N≅∠R

therefore

MN=PR

substitute the given values

$32=3x-10$

solve for x

$3x=32+10$

$3x=42$

$x=14$

If a line has a slope of 4 and goes through the point open parentheses short dash 1 comma 1 close parentheses, then the equation

san4es73 [151]

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the line will be y =4x+5. Thus, the correct option is C.

<h3>What is the equation of a line?</h3>

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

Given the slope of the line is 4 and it goes through (-1,1), therefore, the equation of the line will be,

y = mx + c

y = 4x + c

Substitute the value of points,

1 = 4(-1) + c

1 = -4 + c

5 = c

Hence, the equation of the line will be y =4x+5. Thus, the correct option is C.

A quantity with an initial value of 4000 grows exponentially at a rate of 0.05% every 5 decades. What is the value of the quanti

icang [17]

The value of the quantity after 1 year, to the nearest hundredth is 4000.00

<h3>The exponential form of an equation</h3>

The standard exponential equation is eexpressed as:

$P(t)=P_0e^{kt}$

Given the following parameters

$P_0=4000\\r =0.0005\\t = \frac{1}{50} =0.02 (yearly)$

Substitute into the formula to have:

$P(t)=4000e^{0.0005(0.02)}\\P(1)=4000e^{0.00001}\\P(1)=4000$

Hence the value of the quantity after 1 year, to the nearest hundredth is 4000.00
