Answer:

y = 2x + 15

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = 2 , then

y = 2x + c ← is the partial equation

to find c substitute (- 4, 7 ) into the partial equation

7 = - 8 + c ⇒ c = 7 + 8 = 15

y = 2x + 15 ← equation of line

What is 3/4- (-5 1/4) =<br><br> NEED HELP ASAP

Fantom [35]

Answer:

Step-by-step explanation:

$\frac{3}{4} - (-5\frac{1}{4})$

-5 1/4 is a mixed fraction. so we convert it into improper fraction

$-5\frac{1}{4}=-\frac{5*4 +1}{4}=-\frac{21}{4}$

$\frac{3}{4} - (-\frac{21}{4})$

negative and negative becomes positive

$\frac{3}{4} +\frac{21}{4}$

Both fractions have same denominators. so we can combine the numerators

$\frac{3+21}{4}=\frac{24}{4}$

Divide the fraction

$\frac{24}{4}=6$

Find the distance between the two points. (-2,1) (1,-2) Enter the number that goes beneath the radical symbol

qaws [65]

Answer:

4.242641

Step-by-step explanation:

d= $\sqrt{(1-(-2))^{2}+(-2-1)^{2} }$

d= $\sqrt{(3)^{2} + (-3)^{2} }$

d= $\sqrt{9+9}$

d= $\sqrt{18}$

d=4.242641

In ΔUVW, the measure of ∠W=90°, the measure of ∠U=40°, and WU = 1.8 feet. Find the length of UV to the nearest tenth of a foot.

Dmitry_Shevchenko [17]

Answer: 2.3

Step-by-step explanation:

1.8

\cos 40=\frac{1.8}{x}

cos40=

1.8

x\cos 40=1.8

xcos40=1.8

Cross multiply.

\frac{x\cos 40}{\cos 40}=\frac{1.8}{\cos 40}

cos40

xcos40

cos40

1.8

Divide each side by cos 40.

x=\frac{1.8}{\cos 40}=2.3497\approx 2.3\text{ feet}

cos40

1.8

=2.3497≈2.3 feet
