Find the slope of the line give these two points: (0,5) and (-7, -8) *

PSYCHO15rus [73]

Answer:

m=13/7

Step-by-step explanation:

the equation for slope (m) is (y2-y1)/(x2-x1)

the given points are (0,5) and (-7,-8)

we can label them:

x1=0

y1=5

x2=-7

y2=-8

now substitute into the equation

m=(-8-5)/(-7-0)

m=-13/-7

m=13/7

the slope is 13/7

hope this helps!

George was given 11 grams of medicine, but the full dose is supposed to be 25 grams. What percent of his full dose did George re

Bess [88]

Answer: George receive 44 % of his full dose .

Step-by-step explanation:

Given : The amount for full dose : 25 grams

The amount received by George = 11 grams

Now, the percent of his full dose received by George :-

$\dfrac{\text{Dose taken by George}}{\text{Full dose}}\times100$

$=\dfrac{11}{25}\times100=44\%$

Hence, George receive 44 % of his full dose .

Devon wants to write an equation for a line that passes through 2 of the data points he has collected. The points are (8, 5) and

iren2701 [21]

<span> If the model is good, then both points will check in the equation. Substituting 8 for </span>x <span>and 5 for </span>y<span> in the equation results in 56 – 50 = 3, which is not true. Therefore, the model is not good. Using (–12, –9) as a check results in –84 + 90 = 3. The constant value in the equation should be 6, not 3. In slope-intercept form, the </span>y<span>-intercept should be –3/5.</span>

Evaluate each expression.

KonstantinChe [14]

Answer:

Please check the explanation.

Step-by-step explanation:

Solving the expressions

7)

given the expression

$\left(-7\right)+\:\left(-10\right)\:-\:5\:+2$

$\mathrm{Follow\:the\:PEMDAS\:order\:of\:operations}$

$\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}\:\:$

$\mathrm{Apply\:rule\:}+\left(-a\right)\:=\:-a$

so

$=\left(-7\right)-10-5+2$

$=-17-5+2$

$=-22+2$

$=-20$

8)

$\left(-9\right)+4+\left(-8\right)-\left(-7\right)$

$\mathrm{Follow\:the\:PEMDAS\:order\:of\:operations}$

$\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}\:\:$

$\mathrm{Apply\:rule\:}+\left(-a\right)\:=\:-a$

so

$=-5+\left(-8\right)-\left(-7\right)$

$=-5-8-\left(-7\right)$

$=-13-\left(-7\right)$

$=-13+7$

$=-6$

9)

$\left(-6\right)\:-\:\left(2\:\times \:4\right)\:-\:\left(-1\right)\:$

$\mathrm{Follow\:the\:PEMDAS\:order\:of\:operations}$

$\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}\:\:$

so

$\left(-6\right)-\left(2\times \:4\right)-\left(-1\right)$

Calculate within parentheses

$=\left(-6\right)-8-\left(-1\right)$

$=-14-\left(-1\right)$

$=-14+1$

$=-13$

10)

$\left(-8\right)\:+\:\left(-4\:\div \:-4\right)\:-\:8$

solving

$\left(-8\right)+\left(-\frac{4}{-4}\right)-8$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a$

$=-8-\frac{4}{-4}-8$

$=-8-\left(-1\right)-8$

$\mathrm{Apply\:rule}\:-\left(-a\right)=a$

$=-8+1-8$

$\mathrm{Add/Subtract\:the\:numbers:}\:-8+1-8=-15$

$=-15$
